Tomball, TX, during the mid-afternoon.


Summary: The day was hot, sunny, and dry. Some isolated moderately heavy to really heavy showers and thunderstorms in the Houston, TX area, during the morning, afternoon, evening, and maybe night. There looked to be some isolated moderately heavy to heavy and maybe really heavy, showers and thunderstorms in the Woodlands, TX area, during the evening. I was told that there was fog in the early morning, in the Woodlands, TX area. I don't know if there was any fog in the Houston, TX area. I didn't see, feel, or hear any rain drops, or see any fog. Alto stratus, stratus and stratocumulus clouds looked to be scattered across the sky, during the early and mid-morning. Alto stratus, stratus, and stratocumulus clouds looked to be widely scattered across the sky, during the late morning, afternoon, and early evening. The sky looked to be clear, or maybe mostly clear, during the late evening and early night. The wind speeds looked to be calm with maybe some gentle to moderate gusts and maybe some moderately strong gusts. It felt warm, during the early morning and night. It felt very warm, almost hot, during the mid-morning. It felt hot, during the late morning, afternoon, and early evening. It started to feel warm, from feeling hot, during the late evening. There were no watches, warnings, alerts, advisories, or weather statements/outlooks issued for the Houston, TX area, that I know of. The low temps looked to be in the 70's and the high temps looked to be in the 90's, for the Houston, TX area.


Houston, TX and The Woodlands, TX Storm Summary: There looked to be some isolated moderately heavy to really heavy showers and thunderstorms in the Houston, TX area, during the late morning, afternoon, evening, and maybe night. There looked to be a few isolated moderately heavy to heavy and maybe really heavy showers and thunderstorms in the Houston, TX area, during the evening. I also heard that there was some fog in the Woodlands, TX area, during the early morning. I didn't hear about any flooding, or storm damages. There are still roads closed because of Harvey in the Houston, TX area. I do not know if these closed roads still have water covering them.


My Storm Summary: I didn't see, feel, or hear any rain drops. I didn't see any storm clouds, wet roads, flooding, or lightning strikes. I didn't hear any rumbles of thunder. I may have seen a few small puddles of water on the sides of streets, but I don't remember. I did see a Animal Hospital that looked to be closed because of Harvey, in northwest Houston, TX, on my way to The Woodlands, TX.


Locations: Nortthwest, west, and southwest Houston, TX, Tomball, TX, Woodlands, TX, and maybe Klien, TX.


Thoughts: It felt pretty hot today. The pool water actually felt nice, even though the thermometer only read 82 degrees. Which can sometimes feel really cool in a pool. 85 degrees is the ideal warm temperature in a swimming pool.

.DISCUSSION...
Quick update to clear out skies and lower pops overnight.

&&

.AVIATION...
Skies clearing out rapidly and expect winds to decouple at most
sites by 06z. Patchy fog a good bet at the rural sites and may see
some MIFG at IAH. By 13-14z skies become CU filed with SCT
possibly BKN VFR CIGS for a few hours 14-16z. Narrow band of
moisture lingers along the I-10 corridor and could get a few
showers or even a thunderstorm but coverage looks less than today
with subsidence increasing on northeasterly flow aloft edging down
over the region. Will hold off on VCSH/VCTS as expectation for
coverage is so low.

.PREV DISCUSSION... /ISSUED 335 PM CDT Fri Sep 22 2017/

DISCUSSION...
Best shower/thunderstorm coverage so far today has been in/around
the Matagorda Bay and Jackson County areas where the highest moisture
levels have been found. Isolated to widely scattered storm development
is still possible across the rest of our area over the next several
hours (peak heating) with all activity expected to dissipate early
this evening. The area still looks to be on the warm and dry side
over the weekend with only spotty mainly daytime shower/thunderstorm
development anticipated. Models are generally trending next week`s
increasing rain chances associated with an approaching storm system
and accompanying cold front to be setting up across the western and
central parts of the state as weak mid/upper level ridging centered
out in the Gulf tries to be a player for our area. Once the ridging
breaks and we do get the front on through, look for some drier and
slightly cooler weather to eventually work its way into our area. 42

MARINE...
Light to moderate onshore winds, seas around 2 to 3 feet,
and periods of showers and thunderstorms are expected across
the waters this weekend and into next week. A cold front may
push off the coast late in the week next week. Tides continue
to run about 0.5 to 1 foot above normal but should remain
below any critical thresholds for impacts.

PREV DISCUSSION... /ISSUED 1238 PM CDT Fri Sep 22 2017/

AVIATION...
A few isolated showers and storms will be possible across the
western portion of the area today, but coverage is expected to be
too low to include in the tafs. Expect some fog/low stratus once
again overnight tonight and into tomorrow morning, with the
greatest potential north of KIAH. Conditions will probably be
slightly better than what occurred this morning due to slightly
less available moisture. Any fog/low cigs that do develop will
improve around mid-morning, with VFR conditions expected for the
rest of the period. Isolated showers and storms will be possible
once again tomorrow afternoon, but coverage is expected to be too
sparse to include in this taf package.

Northwest Houston, TX, during the early evening.
Northwest Houston, TX, during the late evening.


Summary: The day was mostly cloudy, mostly wet, and warm. Isolated to scattered moderately heavy to really heavy showers and thunderstorms passed over the Houston, TX area, during the late morning, afternoon, evening, and  maybe night. A moderately heavy to heavy thunderstorm passed over where I work, in northwest Houston, TX, during the early afternoon. Alto stratus, stratus and stratocumulus clouds looked to cover most of the sky, during the morning, afternoon, evening, and maybe night. The wind speeds looked to be calm with gentle to moderate gusts with some moderately strong gusts, and maybe some occasional really strong (20 mph) gusts. It felt warm, during the early morning, afternoon, evening, and night. It felt very warm, during the mid-morning. It felt hot, during the late morning. There was a Flash Flood Warning and Advisory issued, along with probably many other advisories, warnings, and watches, for the Houston, TX area. There was also a Hazardous Weather Outlook issued for the Houston, TX area, by NOAA. The low temps looked to be in the 70's and the high temps looked to be in the 80's with maybe some 90's, for the Houston, TX area.


Houston, TX Storm Summary: Isolated to scattered showers and thunderstorms passed through the Houston, TX area, bringing moderately heavy to really heavy rain to some areas of Houston, TX, during the late morning, afternoon, evening, and maybe night. Flash flooding did occur in some areas of Houston, TX. I didn't hear about any storm damages.


My Storm Summary: A moderately heavy to heavy thunderstorm passed over where I work, in northwest Houston, TX, during the early afternoon. I saw a few big puddles, but no flooding. I didn't see any storm damages. I saw a few lightning strikes. I may even have saw some cloud-to-ground lightning strikes, that may have caused a few car alarms to go off. Near where I work, in northwest Houston, TX. I heard a few loud and deep rumbles of thunder, during the early and maybe mid-afternoon.


Locations: Northwest and west Houston, TX.


Thoughts: More rain for the Houston, TX area. I didn't see as much rain, as some Houstonians saw today.

.AVIATION...
Some changes with the 00Z TAFS - lowered CIGS/VIS a bit for to-
night/early Fri morning for some sites and added the mention of
VCSH for most sites tomorrow afternoon. Widespread showers this
afternoon should give way to clearing skies,light winds and wet
grounds across the area tonight. These conditions will be favo-
rable for the development of some patchy fog/low clouds tonight
through sunrise tomorrow morning...in particular locations just
north of IAH. While most models are drying things out tomorrow,
still not confident enough to not mention at least VCSH for the
afternoon hours tomorrow. Of note, NAM is the lone outlier, and
has a slug of 2" PWs moving in from the west tomorrow afternoon.
41

.PREV DISCUSSION... /ISSUED 332 PM CDT Thu Sep 21 2017/

Scattered to numerous slow moving showers and thunderstorms
continue across Southeast Texas this afternoon as a disturbance
moves eastward across the area. The slow moving activity and
precipitable water values above 2 inches have brought locally
heavy rainfall to the area resulting in several
advisories/warnings. At one point, a Harris County Flood Warning
System rain gage (Cypress Creek at Huffmeister) had rainfall rates
of 0.48 inches in 5 minutes and 0.80 inches in 10 minutes. Expect
decreasing coverage/intensity late this afternoon through early
this evening. The area remains on the southern fringes of ridging
both at the surface and aloft, and enough heating should allow for
some mainly daytime shower and thunderstorm development over the
next several days. But compared to today, expect to see much less
coverage for the end of the week and over the weekend with lower
precipitable water values. Still looking at an eventual increase
in rain chances next week as mid/upper level ridging edges
eastward and a western U.S. trough gradually works its way toward
the east. Will be carrying higher rain chances as we head on into
the middle to end of the week when the trough and associated slow
moving cold front begin to work their way toward our area. Will
need to keep a close eye on model trends over the next several
days as some have precipitable water values approaching a very
high 2.50 inches under the persistent onshore flow ahead of the
slow moving boundary. This potential heavy rain event is still
many days away, and a lot can change with the models. Obviously,
our area does not need to see another significant rainfall event
as the Harvey recovery continues. 42

Area Forecast Discussion
National Weather Service Houston/Galveston TX
652 PM CDT Tue Sep 19 2017

.AVIATION...
Widely scattered storms winding down this evening with the loss of
daytime heating. Will be keeping an eye out west with the activity
associated with an eastward moving shortwave, but will also be ex-
pecting this activity to die off shortly after sunset. MVFR to IFR
CIGS will be possible across the area overnight (particularly over
our northern inland sites)...but the best chances for some ISO WAA
type showers will be closer to the coast. With a slightly more ac-
tive southern stream jet have added the mention of VCSH for all of
the TAFS tomorrow. 41

&&

.PREV DISCUSSION... /ISSUED 316 PM CDT Tue Sep 19 2017/

More typical late summer weather in Southeast Texas for the next
several days. Several very subtle features will impact the
forecast into early next week. This makes the forecasting process
intriguing, but the impacts appear to be mostly limited to
temperature changes of a few degrees and just how scattered the
scattered showers and storms will be. Based on how how these
subtleties play out, things like preferred days for more numerous
showers may shift a bit in the coming days. However, the broad
concept of typical late summer weather seems clear. Of course,
"typical" does not always mean "no hazards". The strongest of each
day`s storms can be capable of some gusty winds and/or locally
heavy rainfall. This is the type of setup in which one gauge might
see 4 inches of rain, while another gauge nearby sees about a
third of an inch.

NEAR TERM [Through Tonight]...

A subtle, but readily apparent shortwave ridge is beginning to exit
Southeast Texas per analysis and water vapor imagery. Its impact on
today`s convection has been similarly apparent, with considerably
fewer showers and storms so far today. However, it appears the next
weak shortwave trough will begin to approach the region, and is
attended by an uptick in convective activity to our west. This may
mean a little more activity for the late afternoon until we lose
heating this evening, but we still look unlikely to match
yesterday`s activity. Temperatures today have been a little higher
than forecast as convection so far has been even more limited than
already expected. But with thoughts that clouds may tick up in the
next few hours and our lows look to be governed at least in part by
the high dewpoint floor, don`t think it will have a very significant
effect outside of these first few hours of the forecast.

SHORT TERM [Wednesday Through Thursday Night]...

By Wednesday, a new shortwave trough will be crossing the area,
which should provide some upward boost to that day`s convection.
Now, that said, this doesn`t seem to appear in all of the guidance,
which ranges from virtually dry (NAM) to decently wet. It`s worth
noting that guidance does seem to step precipitable water values
down a little from the two inch numbers we`ve seen of late, and
there may be some timing issues - a slightly faster shortwave may
put us just on the subsident side of the trough by late afternoon.
This could hamper convective development as well.

Probably don`t want to get too terribly wrapped up in the details as
the difference in impacts isn`t huge. What there does seem a clearer
signal of in the guidance is that a coastal boundary looks to be the
primary focus for convection, and we still have enough moisture to
produce locally heavy rainfall. The NCAR WRF ensemble shows a fair
to strong signal for some locally heavy rain along the coast. The
strongest signal looks to lie just east of our area closer to the
TX/LA border, but there`s surely some potential for cells dropping a
quick few inches here.

For Thursday, cyclonic flow aloft looks to stay in place, and give
us stable or slightly falling midlevel heights over the area again
on Thursday. This would bolster the idea the previous shift had that
Thursday could see one more day of relatively higher coverage in
showers and storms. This may be somewhat subject to change as the
broad eastern US ridge will be starting to amplify, and could see a
scenario in which we actually are drier on Thursday. However, given
the relative consistency in seeing a developing upper low on the
Gulf Coast in the models, will hold onto the idea of a wetter
Thursday.

LONG TERM [Friday Through Tuesday]...

Guidance continues to show a trend to an amplifying west trough/east
ridge pattern, but also with an upper low developing along the
northern Gulf Coast. Farther to the east, Jose and Maria continue to
have a tricky interaction - this dance of tropical cyclones won`t be
directly impacting our weather, but I do wonder how it may impact
the aforementioned upper low, as our precip chances this weekend
into early next week may be influenced by just how far west it gets
before being drawn back up into the northern stream westerlies.
Because of this, I try to work in broad strokes on the PoPs with
less variation than I might normally. In general, go a little lower
Friday and Saturday, and a bump up for the rest of the weekend into
early next week. This is not a significant difference from the
previous shift, which had similar trends. As far as temps go, I
don`t see heights going low enough to really imply a big shift in
temperatures, but do get a couple degrees cooler on highs as we head
deeper into the weekend.

It`s beyond the scope of the forecast, but models diverge
significantly later next week as a cold front drags into Texas and
potentially towards the area. There is precious little agreement in
the models outside of the existence of a front, however, so details
on this will have to be sussed out in the coming week.

Alto stratus and stratus with maybe some stratocumulus clouds looked to cover most of the sky, during the morning and early and mid-afternoon. Stratus and nimbus clouds looked to cover the whole sky, during the late afternoon and early evening. Stratus and nimbus clouds looked to cover only most of the sky by the late evening and early and maybe late night. The wind speeds looked to be calm with maybe some gentle to moderate gusts. It felt very warm, during the early and mid-morning. It started to feel hot, during the late morning. It felt very warm, maybe hot, during the early and mid-afternoon.

The low temps looked to be in the 70's with maybe some 60's and the high temps looked to be in the 80's with maybe some 90's, for the Houston, TX area.


Houston, TX Storm Summary: Scattered showers and thunderstorms dumped moderately heavy to really heavy rain causing flash flooding, back into the Houston, TX area. I didn't hear about any storm damages. A few roads are still closed because of Harvey.


My Storm Summary: I first started to see some moderate to moderately heavy rain while at work in northwest Houston, TX, during the late morning and early afternoon. Moderately heavy to really heavy rain was falling on my home and to Great Clips in northwest Houston, TX, during the late afternoon and evening. I was going to go to the Great Clips in west Houston, TX, that I normally go to, but the rain and traffic were really bad. I saw some flash flooding, but no storm damages from the showers and thunderstorms. I did find a knocked over street sign today, lying in a ditch next to where I work, which I assumed was from Harvey, or from something else, like vandalls, or maybe road construction. 


Locations: Northwest Houston, TX.


Thoughts: A lot heavier rain than I expected to see today.

.UPDATE...
A little bit of action early this evening as a cluster of
thunderstorms slowed over southern Harris...northern Fort Bend
and Brazoria Counties and produced a quick 2 to nearly 5 inches
of rain in about two hours. These high rainfall rates lead to
minor street flooding/ponding from downtown Houston across southeast
Houston through the 8 PM hour. This first mentionable post-Harvey
thunderstorm activity quickly weakened through 8 PM hour and radar
has since become very quiet. Lower rain chances forecast Tuesday
as a relatively drier air mass just offshore of the upper Texas
coast comes onshore tomorrow. Flat zonal upper ridging with
surface high pressure parked over the northern Gulf should aid in
suppressing areawide TSRA activity. Anticipating more localized
-TSRA tomorrow (along local breezes?) with 30% areal coverage or
less from returning late morning through afternoon convection. 31

AVIATION...
Cluster of storms, producing heavy rain (lightning and reduced
visibility) around the Hobby and Sugarland terminals will last
for another hour or two. Do expect all precip to taper off fairly
quickly with the loss of heating. VFR conditions for the remainder
of the evening. But with wet ground from todays precip, along with
light wind and mclr skies, would anticipate some fog to develop.
Confidence on timing/location/significance isn`t all that high but
initial thoughts are reflected in the TAFs. Suspect they may need
to be amended to be more pessimistic if anything. Otherwise, not
quite as much available moisture is expected on Tue compared to
today. So although we`ll probably see some sct tstms with daytime
heating, areal coverage probably won`t be as widespread. Similar
pattern should exist going into midweek. 47
