.AVIATION...

VFR to start the 21/00Z TAFs. Areas of MVFR ceilings and possible fog
developing overnight with ESE to SE winds at 5 to 10 knots. MVFR ceilings

.PREV DISCUSSION... /ISSUED 314 PM CST Sat Feb 20 2021/

SHORT TERM [Tonight Through Sunday Night]...

Surface high pressure has moved off to the east allowing for
southerly winds and warmer temperatures to prevail across the
region. Tonight will be the first night in a long while where no one
across the CWA has freezing temps in the overnight forecast. Even
warmer conditions expected tomorrow, though we`ll see some
increasing cloudiness as shallow Gulf moisture continues its return
to the area. The cold snap has caused a significant drop in water
temperatures near the coast (40s-mid 50s) so would anticipate some
sea fog development later in the day and evening Sunday as warmer
air overspreads. The next front should be moving into northern parts
of the region Sunday evening and off the coast by 3am or so. Look
for a specking of -ra as it approaches...probably consolidating into
a thin band of -ra as it approaches the US59 & I-10 corridor
southward. (Nothing of significance & no threat of frozen precip.) 47

LONG TERM [Monday Through Saturday]...

A much welcomed warming trend is expected to take hold through the
middle of the upcoming week in the wake of the departing surface
cold front on Monday. We`ll see a bit of a drop off in high
temperatures (50s to low 60s) and some chillier lows (mid 30s to
lower 40s) come Monday as moderate northerlies behind the
boundary enhance CAA, though an onshore flow regime quickly
redevelops on Tuesday with surface high pressure behind the cold
frontal boundary departing eastward. As a result, conditions will
make a return to near-seasonable values by mid-week, with highs
reaching the mid 60s on Tuesday afternoon and the lower 70s at
most locations on Wednesday. While the increasing onshore winds
should work to also increase cloudiness during this time, we`ll
generally be seeing some of the most pleasant weather for the
region in quite some time.

Global models, while still divergent towards the end of the
extended forecast period, have come into a bit better agreement
with the 12Z suite of deterministic solutions. In general, the
arrival of the next surface front looks to be on track for
Wednesday Night into Thursday as a boundary extending from a
deepening low over the Great Lakes region traverses the South
Central CONUS. Moisture return ahead of the boundary`s approach
remains a bit stronger in the EC solution compared to the latest
GFS, however expected QPF values have come into a bit better
agreement with showers developing along and ahead of it. Have
continued to include chance PoPs as GFS fropa remains a touch
faster than the EC and Canadian fropa is much faster.

As the boundary reaches the coastal waters, it looks likely to
stall offshore before pushing back northward as a surface warm
front. Precipitation chances look to return headed into the
weekend as this occurs, aided by favorable upper jet dynamics.
Amounts and intensity of this precip event remain uncertain for
the time being, but early consensus seems to suggest a wet weekend
ahead next week.

MARINE...

Surface high pressure continues its eastward progression
overnight, and with deepening pressures over the Four Corners
region an increase in onshore winds is anticipated. By tonight or
early tomorrow, wind speeds are likely to require cautions in the
nearshore and offshore waters as a result. Increasing low-level
moisture combined with abnormally cold sea surface temperatures
will likely prove favorable for marine fog development on Sunday
prior to the arrival of a surface cold front during the overnight
hours. In the wake of this departing front, moderate offshore
winds will likely require another round of cautions. By late
Tuesday, onshore flow quickly redevelops and increasing winds and
seas will be in store before the approach of another surface
boundary towards the end of next week.

Thoughts: There was still some small amounts of snow left at my house, 

during the morning and early afternoon when I stopped by. I did 

not see any more snow when I arrived back my house in Coppefield,

during the early night. I believe all of the snow has melted.

But I will check again tomorrow.

.AVIATION...

Other than some patchy ground fog that might develop overnight and dissipate
around mid-morning tomorrow (mainly CXO area northward), VFR conditions
can be expected with light winds this evening and overnight becoming
SE to S (generally around 5 to 10 knots) late tomorrow morning through
tomorrow afternoon.  42

&&

.PREV DISCUSSION... /ISSUED 303 PM CST Fri Feb 19 2021/

SHORT TERM...(Tonight through Saturday Night)

Although still chilly, conditions have begun to moderate with the
help of abundant sunshine this afternoon. One more night of
freezing temperatures is expected as high pressure settles over SE
TX. Will maintain the Hard Freeze Warning for the N-NW zones but
models have trended a bit warmer for tonight. The rest of SE
Texas will endure a short period of freezing temperatures tonight.
Not real confident with regard to some patchy ground fog that
could develop but the ECMWF, NAM soundings and SREF data support
some freezing fog toward Saturday morning. The T/Td gap narrows
considerably tonight and felt it was best to at least mention some
potential for freezing fog over the northern half of the CWA in
the weather grids.

The surface high will shift east of the region on Saturday with an
onshore flow developing. This will lead to warmer temperatures and
a slight increase in moisture. Should start to see an increase in
clouds by afternoon as the moisture deepens. MaxT values will warm
into the upper 50`s central and south and we have not been that
warm since February 10th. The northern zones will probably remain
in the 40`s. Warm air advection will persist into Saturday night
and low temperatures will probably occur in the evening and either
hold steady or slowly rise as onshore winds continue to draw low
level moisture into the area. The WAA pattern will allow for
patchy fog and perhaps some drizzle late Saturday night. 43

LONG TERM [Sunday Through Friday]...

Some long-awaited warmth finally arrives on Sunday, when the return
of onshore flow should continue to promote WAA and push highs into
the 60s across the majority of SE TX. As a deepening surface low
approaches the great plains region, a cold front extending from this
feature will push through the central CONUS during the day on Sunday
and approach SE TX on Sunday night. With the boundary pushing
offshore by Monday, along with some isolated showers along and ahead
of it, another cooldown is expected. Fortunately, this will not be
close in magnitude to what we`ve experienced this week. That being
said, northerly winds behind the departing boundary will allow for
enhanced CAA and thus lows in the upper 30s to low 40s are on tap
for Sunday night and into Monday morning.

High pressure settles into the South Central CONUS following the
departure of the surface cold front, though its presence will be
short lived as its center advances fairly quickly into the central
Gulf by Monday. With onshore flow redeveloping at this time, a warm-
up into mid week will finally give us our first taste of seasonable
weather in quite some time. High temperatures will push into the
mid/upper 60s at most locations on Tuesday and the 70s across much
of the area Wednesday. Increasing cloudiness associated with onshore
Gulf moisture transport will inhibit nocturnal cooling by mid-week,
with lows on Wednesday and Thursday remaining in the upper 40s/low
50s.

Our next shot at widespread measurable rainfall (and perhaps some
isolated thunderstorms) looks to arrive on Thursday as our next
surface cold front pushes towards SE TX. Global models still not
fully on board in depicting this event with EC showing a slower
fropa than most recent GFS & Canadian solutions, though each
solution indicates more robust precip coverage/QPF with this
next system.

Cady

MARINE...

With winds and seas diminishing this afternoon, cautions and
advisories have been allowed to expire as the surface pressure
gradient continues to loosen. Furthermore, we`ve allowed the Low
Water Advisory for Galveston Bay to expire with the expected
improvement in wind conditions and upon today`s high tide.
Conditions remain calm through the weekend before an approaching
cold front in the overnight hours of Sunday will leave another round
of moderate offshore winds and building seas in its wake. Despite
this, the boundary is expected to be weaker than that experienced
this week and as a result conditions are unlikely to exceed caution
thresholds. Onshore winds will quickly redevelop by late Monday as
high pressure behind the departing front shifts quickly towards the
Central Gulf.

Thoughts: The last of the winter weather has finally departed Houston, TX

with the last of the hard freeze warnings expiring this morning and most 

of the ice/snow melthing. There is still some ice/snow on the ground!

Reminds me of when I use to visit my relatives in the northeast and

there would be ice/snow on the ground from a snow storm, or recent 

snow a couple of days, or a week ago. When I was a kid. Kind of

cool I think anyway.

Not much change in the forecast. Ceilings between 400 to 700 feet
will continue through the night with a breezy north wind. Scattered
light freezing drizzle possible across the northern half of the
area impacting generally IAH northward beginning around 6z
transitioning to scattered light snow showers by the early morning

.PREV DISCUSSION /Issued 301 PM CST Wed Feb 17 2021/...

.SHORT TERM...(Tonight through Thursday Night)

Low pressure over the western Gulf has moved east and colder air
will funnel into SE TX in the wake of the low. Colder temperatures
will continue to surge back into SE TX tonight and only persistent
cloud cover will mitigate a stronger temperature fall. That said,
MinT values will likely bottom out in the mid 20`s far NW to
around 30 over the south. Residual water on area roadways will
likely refreeze creating icy conditions on area highways/roads and
drivers should exercise extreme caution if venturing out tonight.
Ice that accumulated on trees and powerlines will not melt and
this could also create some trouble if branches should fall on
structures or take down power lines. Since the heavy icing that
occurred this morning has ended but the risk from residual icing
remains and additional light winter precip is expected later
tonight, feel a Winter Weather Advisory is more applicable than a
Winter Storm Warning in regards to discussing the ice hazard and
possible winter precip.

Most of the precipitation has exited the area but weak upper
level troughing remains over the state and a weak disturbance
embedded in the W-SW upper flow will bring additional
precipitation to the region later tonight into early Thursday.
Fcst soundings and thickness values support a mixture of light sleet
and snow changing to all light snow on Thursday morning. Moisture
levels look meager and fcst soundings show a lot of dry air in
the 850-700 mb layer so not expecting much more than a dusting.
That said, there is some fairly strong 850-700 mb frontogenetic
forcing from Columbus to Houston. Sometimes, the forcing is
strong to compensate for a lack of moisture so it`s something
that bears watching. MaxT values won`t warm much on Thursday and
will struggle to reach freezing at KCLL and probably only warm
into the upper 30`s at KIAH and points southward. Could get a peak
of sun late Thursday afternoon as subsidence develops in the wake
of the morning short wave.

Skies will clear Thursday night and temperatures will once again
plunge to very cold values with mid teens likely by sunrise
generally north of a Brenham to Trinity line. Temperatures will
fall into the lower and mid 20`s over the southern half of the
region. A Hard Freeze Watch will be in effect for Thu Night into
early Friday. SE TX will be looking at another 10-16 hours below
freezing and probably 8 to 10 hours below 25 degrees north of the
Brenham-Trinity line. Another Wind Chill Advisory or Warning may
also be required as Wind Chill values are expected to fall into
the single digits north and teens central. 43


.LONG TERM [Friday through next Wednesday]...

I`ll start off with the bad news. Hard freeze conditions return on
Friday morning as surface high pressure settles into the South
Central CONUS and northerlies strengthen, with residents of the
northern counties expected to experience temperatures in the teens
once again as the sun rises while the Houston metro unlikely to
break 30 degrees overnight. As a result, we have issued a Hard
Freeze Watch for all non-coastal counties during this time.
Residents impacted by the current power outage situation should plan
to continue to take protective actions as the subfreezing
temperatures continue. Highs on Friday afternoon will reach the mid
30s to mid 40s, a slight increase over the previous day as a
relaxing surface pressure gradient moderates CAA.

The remainder of the long-term forecast period brings some better
news. One more night of subfreezing temperatures will arrive on
Friday evening, with lows once again dipping into the upper teens to
20s at most locations as clearing promotes more efficient nocturnal
cooling. However, by Saturday, an eastward shift of surface high
pressure will bring about a long-awaited return to an onshore flow
pattern which will gradually work to increase temperatures and dew
points through the weekend. Most locations finally see the 50s on
Saturday and subfreezing overnight lows finally cease. More
seasonable, but still below average temperatures return on Sunday as
continued WAA allows for highs in the upper 50s to low 60s.

A developing lee cyclone will push into the Great Lakes region as
troughing becomes dominant over the Central CONUS by early Monday,
and a surface cold front extending from this feature will approach
SE Texas. Fortunately, the passage of this feature looks to be
relatively uneventful. The main question continues to be the extend
to which scattered showers will accompany the approaching front.
Latest GFS & Canadian solutions indicate more ample moisture return
and as a result more precipitation as the front pushes through the
area by Monday afternoon. The EC remains drier with less
precipitation coverage. Have included slight chance PoPs for most
locations for the time being, but this will likely need adjusting
based on model consensus over the next couple of days.

Temperatures cool a bit with the fropa though am not currently
carrying any subfreezing overnight lows on Monday. Clearer and
gradually warming conditions look to persist through mid week with
highs on Wednesday breaking back into the 70s.

Cady

.MARINE...

Strong winds continue over the NW Gulf in response to a very tight
pressure gradient surrounding the departing coastal low. Sustained
winds have been around 25 knots with gusts near Gale force. Seas
have increased to 13 feet near buoy19 and marine conditions will
not change much overnight with only a gentle relaxation of the
gradient expected. Will maintain an SCA for the Gulf and bays
through 10z Friday and will continue the SCA for the Gulf waters
through 18z. A 1035 mb surface high will build into the southern
plains on Thursday and surge into South Texas Thursday night keep
the gradient tight. The surface high will drift over the west Gulf
on Friday with offshore winds relaxing. The high will move east
toward the Tennessee Valley on Saturday. This will allow for
onshore winds to return and persist through Sunday. Another cold
front will move across the coastal waters late Sunday night with
an offshore developing in the wake of the front. Offshore winds
will prevail on Monday as surface high pressure settles over East
Texas. 43

Thoughts: Another round of freezing rain with some possible snow 
and sleet fell across the Houston, TX area this morning
and maybe early afternoon. I believe that my dad said that
he saw some snow flakes sometime this morning. There was
a new formed thin layer of ice covering my car this morning
but not enough to prevent me to try and go to work.
Was sent home from work due to a low grade fever.
but am doing ok now. Possibly from the dramatic
temperature changes that is all. Last round of
frozen precipitation expected to fall tomorrow
Thursday morning. My house in the Cooperfield area
has had power for most of the day. It went out
for a for more then a few hours during the 
monrning and afternoon but has stayed on since
sometime during the early or mid-afternoon.
I am hoping that the power continues to stay on
through the night but we will see. We still
have running and hot water. What a mess!!!!!
My heart goes out to everyone in this.

.AVIATION [00Z TAF Issuance]...

Another challenging TAF cycle ahead as another winter storm makes
its way into Southeast Texas. Conditions are VFR now, but will
degrade tonight with lowering CIGs and increasing rain chances
overnight. Think the pre-storm onshore flow will keep HOU, LBX,
and GLS warm enough to avoid FZRA, though HOU will particularly be
on a razor`s edge. SGR, IAH, and CXO are currently set to start
with FZRA, but transition to SHRA/RA as warmer air filters north.
A brief transition may be possible at CLL and UTS, but would be
short and go back to FZRA/SHSN as cold air surged in as the storm
exits. To simplify a complex TAF (too late!), I don`t bother to
show a transition from FZRA at those two sites.

Multiple amendments seem likely. However, it is worth mentioning
that communications and/or power problems have plagued multiple
sites, and we are currently unable to reach SGR or LBX. We will do
our best to keep the TAF current, but because of the lack of obs,
have added AMD NOT SKED to those two.

.PREV DISCUSSION /Issued 341 PM CST Tue Feb 16 2021/...

.SHORT TERM [Tonight Through Wednesday Night]...

Weather conditions will be deteriorating tonight as low pressure
develops south of the Matagorda Bay area. As this low moves into
our coastal waters overnight and on through the waters Wednesday
morning, light precipitation will develop and spread inland while
shortwaves from the upper trof to our west scrape across the northern
parts of our area. Some icing could develop this evening where
precipitation falls near areas around freezing. The real mess looks
to begin to develop after midnight as the freezing line moves slowly
inland. Expecting increasing precipitation coverage during the
overnight through morning hours with significant icing possible
the further north you go. After looking at area soundings and model
trends, it still looks like locations north of Highway 105 will have
the greatest potential for the highest ice accumulation totals of
around 1/4 inch or higher. If this occurs, there could be devastating
impacts to structures, powerlines and agriculture. Of course, driving
should not occur - Stay home! Even areas south of Highway 105 to the
I-10 corridor will be susceptible to icing with potential totals of
around 1/10 to 1/4 inch (1/10 closer to I-10 and 1/4 closer to Highway
105). Again, the safety risk is too great to get on the roads - Stay
home! Improving conditions do not look to occur until late tomorrow
morning or early tomorrow afternoon when activity starts to come to
an end from west to east. With temperatures not expected to rise much
above freezing tomorrow afternoon (especially up north), any freezing
ice that has accumulated will be sticking around, and any melted ice
will freeze over again tomorrow night through Thursday morning with
temperatures in the 20s/30s.

Hang in there...warmer temperatures are coming! 42


.LONG TERM [Thursday Through Monday]...

Residual moisture in the wake of the departing surface low/cold
front may result in some lingering wintry precipitation heading into
Thursday morning, with light snow showers/sleet/ice pellets a
possibility. That being said, impacts from this spotty precipitation
are likely to be minor in comparison to the weather we anticipate
impacting the area in the immediate term. Behind the departing
system, northerly winds will result in another frigid day across SE
TX, with highs in the mid-30s inland to low 40s near the coast and
widespread overnight lows in the upper teens to low 20s. Actions to
protect people, pets, plants, and pipes from the persistent extreme
cold should be continued during this time.

Yet another unseasonably cold day, though a drier one, is in store
on friday as high pressure remains dominant over the South Central
CONUS. However, as this surface high pushes eastward as we reach
Saturday, a long-awaited warming trend will begin as we finally see
the re-emergence of an onshore flow pattern. As a result, highs on
Saturday break into the 50s while on Sunday temperatures reach the
mid to upper 60s at most locations.

Increasing moisture upon the redevelopment of southerly winds will
push total PWs back towards the vicinity of 1.0 in on Sunday
afternoon. Our next chance at precipitation (thankfully, it looks
like purely a rain event this time) will come on late Sunday/early
Monday as a surface cold front traverses the area and produces
scattered showers. The surge of cold air behind this departing
boundary will be comparatively weaker and far less persistent, with
lows not reaching below freezing in its wake on Monday night and
highs returning to the upper 60s/mid 70s by Tuesday afternoon.

.MARINE...

Light to moderate east to northeast winds are expected this evening
with gusts from 15 to 20 knots. Marine conditions become hazardous
late tonight ahead of a coastal low moving northward along the upper
Texas coast through Thursday. Gusty conditions and seas from 5 to 8
ft are expected along with scattered showers and a few
thunderstorms. Behind this system, a strong surface high builds in
keeping moderate to strong northwest winds. Therefore, advisory
conditions due to both winds and elevated seas will persist through
late Thursday night. Marine conditions will improve Friday into the
weekend with light south winds and seas up to 3 ft. 05

...WINTER STORM WARNING REMAINS IN EFFECT FROM 6 PM THIS EVENING
TO 6 AM CST THURSDAY...

* WHAT...An approaching low pressure system tonight through
  tomorrow morning will bring a period of dangerous and
  potentially destructive freezing rain across the region with ice
  accumulation anticipated. Amounts are expected to range from a
  trace to a tenth of an inch along and around the Highway 59
  corridor with higher amounts expanding further northward. The
  highest totals from two tenths of an inch to in excess of one
  half inch will be to the north of a line from Bryan/College
  Station to Huntsville to Groveton. Some locations could see
  isolated higher amounts. These would be devastating amounts of
  ice with the potential to create additional power outages.


* WHERE...Inland areas of Southeast Texas.

* WHEN...Tonight through Wednesday morning.

* IMPACTS...Icy conditions will worsen quickly across the region
  tonight with the freezing rain. Very dangerous driving
  conditions from icy roads are expected. Travel should be
  avoided. Vegetation and powerlines will become coated with ice
  and as the ice accumulates will lead to breaking tree limbs and
  power lines. The power outages already present in many locations
  could well worsen. Even though some areas may thaw out briefly
  the potential for refreeze will be high Wednesday night with
  another cold front bringing subfreezing temperatures back across
  the region.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Winter Storm Warning means significant amounts of ice are
expected or occurring.

Travel is expected to become impossible across northern portions
of the area.

The latest road conditions for Texas can be found at
drivetexas.org.

Thoughts: Houston got 3 inches of snow!!!! The ice and snow are
still melthing from yesterday. Our power was out for a good 
32 hours where I live in Copperfield. Power finally came back 
on around 10:30 am today and had been out since around 1:30 am 
Yesterday, Monday morning. I slept under 10 blankets to keep
myself from freezing. There is another round of ice/sleet/
and snow coming to the Houston, TX area tonight and tomorrow
morning. I am excited for this to be over soon!

Area Forecast Discussion
National Weather Service Houston/Galveston TX
544 PM CST Sun Feb 14 2021

.AVIATION [00Z TAF Issuance]...

Major winter storm beginning to unfold, with mix of rain and
wintry precip already occurring as far south as CXO. Houston
terminals should join that crew this evening, and spread even to
GLS overnight. Have gradual transition to FZRA, mixing to SNPL,
and finally SHSN by early tomorrow morning before precip comes to
an end late tomorrow morning or early afternoon. Low MVFR CIGs at
the very best through all of this, but do hint at the back end
some sign of improvement, particularly in the IAH extended
tomorrow evening.

&&

.PREV DISCUSSION /Issued 259 PM CST Sun Feb 14 2021/...

.SHORT TERM [Tonight Through Monday]...

Major winter weather event (a mix of rain, freezing rain, sleet and
snow) will continue to unfold during the remaining afternoon hours,
on through this evening and overnight, and then come to an end from
west to east during the morning hours on Monday as the storm system
moves into and across the state. Look for precipitation coverage on
radar to continue to increase this afternoon and peak during the
overnight and early morning hours. Locations that are already at
or below freezing (mainly northern and western areas) can expect
to see mainly sleet and snow while locations that are near or slightly
above freezing (mainly southern and eastern areas) can expect rain
and freezing rain to more gradually transition to sleet and snow
as temperatures work their way downward. Models generally support
locations up north (CLL to Crockett areas) to receive the higher
snowfall totals of 4 to 6 inches with locally higher amounts,
locations around and to the north of the I-10 to I-59/69 corridor
to receive 1 to 3 inches with locally higher amounts, and near the
coast light accumulations. Areas that remain near or above freezing
the longest have the potential to receive the highest and most
dangerous ice accumulation potentials of 1/10 to 1/4 inch (again,
locally higher amounts possible), and this looks like it might set
up near/around the Houston area and especially for locations off
to their east and southeast. As usual, winter precipitation forecast
is quite challenging for Southeast Texas, and would not be at all
surprised if there are slight shifts in the exact higher amount
locations. With the entire area under a Winter Storm Warning, a
Hard Freeze Warning and a Wind Chill Warning, everyone should rush
to completion all preparations for this major winter weather event.
After the precip event comes to an end from west to east on Monday
morning and afternoon highs struggle to remain in the upper teens
to mid 20s (maybe near 30 at the coast), bitterly cold temperatures
and wind chills will become our next concern as we head on into
Monday night.

Please stay safe out there, remain home and do not travel! 42


.LONG TERM [Monday Night Through Sunday]...

Round one of the winter precipitation will have come to an end by
Monday night. Monday night/Tuesday morning will feature extremely
dangerous arctic temperatures. Low temperatures will be in the
single digits for our northern and western counties, 10-12 degrees
around the Houston metro area, and in the teens further to the south
and along the coast. Wind chill values will be well below zero out
to the north and west and in the single digits elsewhere. Please
take these hazards seriously. The ice and snow will not melt and
hazardous travel conditions will remain in place. Travel is HIGHLY
discouraged through at least Tuesday. Minimize your time outdoors
and wear proper attire if you go outside. You will be at risk of
hypothermia if outdoors for an extended period of time. Afternoon
temperatures on Tuesday are not expected to get above freezing for
most locations north of I-10, so the ice and snow will remain in
place on the roads. It`s not until Wednesday where a brief period of
above-freezing temperatures come into the area as another coastal
low develops and initially pushes in some slightly warmer air. High
temperatures on Wednesday will be in the 30s/40s for inland areas
and in the 50s along the coast. Model consensus is not entirely
there as far as who gets freezing rain and who gets liquid rain
initially on Wednesday morning along with the extent of the
moisture. Our northern counties have the highest chance of seeing
freezing rain in the morning hours before a transition over to rain
as temperatures warm above freezing. Favorable jet mechanics will be
in place with divergence aloft, but differences remain in models on
how quickly the moisture moves out of the area. Current thinking is
that moisture sticks around into Wednesday night/Thursday morning,
so as temperatures drop below freezing we will see a transition over
to winter precipitation at the tail end on Thursday morning for
areas north of I-10. Uncertainty remains on if the winter
precipitation will be freezing rain, sleet, or snow, but leaning
more towards another freezing rain event.

High pressure moves into the area on Thursday and we`ll see clearing
skies with temperatures in the 30s and 40s. Below freezing
temperatures likely to remain in our far northern counties due to
the CAA over the frozen ground. Thursday night/Friday morning will
feature another hard freeze with temperatures dropping into the
teens up north and into the 20s further to the south due to
radiational cooling underneath the mostly clear skies. We won`t be
trapped in this cold weather pattern all week though...warmer
temperatures are on the horizon! High pressure shifts to the east on
Friday afternoon and reintroduces onshore flow to the area.
Resultingly, temperatures will rise into the 40s and 50s across the
area on Friday. If that`s not warm enough for you, temperatures will
be back into the 60s by next weekend as onshore flow persists. 26


.MARINE...

Offshore northeasterly winds of 15-20 knots continue to prevail.
Winds will increase going into the nighttime hours eventually
reaching Gale force tonight through Monday. This is the result of a
coastal low developing in the western Gulf. As it passes through the
area, periods of winter precipitation are anticipated. Additionally,
seas will build up to 10-12 feet offshore and 6-7 feet nearshore
with the strong northeasterly winds. As the low transitions to the
east, strong offshore flow returns in its wake and seas will
gradually decrease on Monday. Low water conditions will be possible
during low tide periods. Another potential hazard for this event
will be freezing spray with the prolonged period of freezing
temperatures through Tuesday before coastal temperatures begin to
rebound. Another coastal low will develop on Tuesday night/Wednesday
morning and bring another period of strong offshore winds.  26

  rain, sleet and snow. Snowfall accumulations of 2 to 6 inches
  are expected north of Highway 105 tapering down to 1/2 to 2
  inches down to the Highway 59 and Interstate 10 corridor.
  Locally higher amounts are possible. This will be on top of a
  layer of ice between 1/10 to 1/4 inch thick. Additionally, it
  will become extremely cold with long stretches of the week spent
  below freezing. Minimum wind chills will fall below zero.

* WHERE...Portions of Southeast Texas.

* WHEN...Though Monday Morning.

* IMPACTS...Travel will continue to be very difficult...if not
  impossible...through Monday morning. Many roads have been
  reported as ice covered and closed this evening. The extremely
  low wind chills as low as 15 below zero will become life
  threatening to people and animals outside without adequate
  warmth or shelter! The strong winds could also result in blowing
  and drifting of snow creating near white out conditions with
  visibility less than 1 mile at times.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A major winter storm is forecast to occur. Preparations to
protect life and property should be rushed to completion. Prepare
for power outages and have non-perishable food and water on hand.
Do not travel unless it is an emergency. If you must travel, keep
an extra blanket, flashlight, food, and water in your vehicle in
case you become stranded.

The latest road conditions for Texas can be found at
drivetexas.org.

A Winter Storm Warning means significant amounts of snow...
sleet...and ice are expected or occurring. Strong winds are also
possible. This will make travel very hazardous or impossible.

A Wind Chill Warning means the combination of very cold air and
strong winds will create dangerously low wind chill values. This
will result in frost bite and lead to hypothermia or death if
precautions are not taken.
