Sep. 27 20

 Not sure how the sky looked but the sun was out, at my house in northwest Houston, TX, during the early morning. The sky looked to be clear with some altostratus clouds scattered across, at my house, during the mid-morning. Alto stratus clouds started to cover most of the sky, during the early afternoon, or maybe late morning, at my house in northwest Houston, TX. Alto stratus clouds were scattered across the sky, at my house in northwest Houston, TX and the Heights, during the early afternoon. Alto stratus clouds were scattered across the sky in West Houston, TX and Katy, TX, during mid and late afternoon and early evening. Alto stratus clouds looked to be scattered across the sky, at my house and neighborhood in northwest Houston, TX, during the late evening. The sky looked to be clear with only one or two alto stratus clouds scattered about, at my house in northwest Houston, TX during the night. The wind speeds were light with some moderate gusts throughout the day. The day very warm, almost hot. There was no rain for the Houston, TX area that I know of. I did not see, or feel any rain drops. There was a 30 percent chance for rain for the Houston, TX area, during the night but I am not sure about the day. May have been a 10 to 20 percent chance.

(Edit: High white alto stratus clouds looked to cover most of the sky, while I was driving my mom around trying to find a open gas station, in my neighborhood in northwest Houston, TX, during 11 pm.)

.AVIATION [00Z TAF Issuance]...

VFR conditions with light to moderate southerly flow will continue
through midnight tonight, but an approaching cold front will bring
a northerly wind shift, MVFR CIGs of around 1500-2000ft, and a
line of showers and thunderstorms to the area late tonight and
into the first part of tomorrow. Looks like this line will be
through CLL around 7-8z, through IAH around 11-12z, then through
GLS and off the coast by 14-16z. As the front passes, it will
bring a line of precipitation with it. Have just kept the VCSH
wording, but an isolated thunderstorm can not be ruled out. Gusty
northerly winds will continue through the day behind the front
with gusts up to 20 to 30mph with the strongest gusts near the
shore. Expect clearing skies through the day as well. Winds relax
a bit overnight tomorrow night, but may still be sustained around
10 to 15 mph.

Important information for our users, the NWS will be completing
some maintenance on our internal network between 1am and 4am CDT.
This will result in a data outage of many of our products and many
products will not be transmitted to external users. Because of
this, all of our TAF sites will include "AMD NOT SKED 2806/2809"
in the 6z package. Unfortunately, this will be when the cold front
will be moving through CLL and UTS, so please be advised that
amendments may not be issued if conditions become unrepresentative.

.PREV DISCUSSION /Issued 305 PM CDT Sun Sep 27 2020/...

.SHORT TERM [Rest of Today through Monday Afternoon]...

Fair but breezy weather conditions will continue today through early
tonight. Partly cloudy skies and winds of 10-15 MPH are expected to
prevail this afternoon with high temperatures reaching the upper 80s
to low 90s. Rain chances will increase tonight into Monday morning
across SE Texas as a cold front moves through the local area.
Locally, we will see showers and possibly isolated thunderstorms
ahead and along the boundary beginning along the northern areas
closer to midnight CDT, spreading into the central areas overnight
and reaching the southern areas early Monday morning. In the wake of
the front, rain chances will dissipate and winds will turn northerly
and increase to around 15 KTS with gusts of around 25 KTS. By Monday
late morning into afternoon, drier air will filter into the region
allowing skies to lift and scatter out starting along the northern
region spreading southward into the rest of the CWA Monday
afternoon/evening. No significant threat is expected with this
frontal passage, but the drier and cooler air mass will decrease
overall temperatures on Monday. High temperatures look to only reach
the mid to upper 70s across areas north of I-10 and the low 80s
across areas south of I-10. Very nice for September in SE Texas! 24


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

The main weather feature in the long term period will be the cooler
overnight low temperatures and the lower daytime humidities. On Tuesday,
Wednesday and Thursday lows will be mostly in the 50s inland and in
the 60s at the coast with Wednesday probably being the coolest as surface
high pressure settles into the area. Tuesday`s highs looks to stay
in the upper 70s to around 80, and then a warmup begins with readings
probably reaching the mid to upper 80s on Thursday. The next cold front
(much weaker and much less breezy/windy than Monday`s front) will work
its way through the area Thursday night through Friday morning. High
pressure behind this front will be centered well to our north as it
moves eastward, and this will bring area winds back around to the
southeast and south for the weekend. Friday`s low temperatures should
be a little cooler than Thursday morning`s readings, and then the area
can expect a gradual rising trend (both temperatures and humidities)
over the weekend.

Do not think anyone would be upset if record low temperatures were reached
during this cooldown, but sorry to say that`s not gonna happen.

.MARINE...

Onshore winds will prevail tonight ahead of a strong cold front that
will move into the coastal waters on Monday morning. In the wake of
the front, strong northerly winds, with gusts possibly close to gale
force, can be expected later in the day and on into Monday night as
cooler air temperatures move across the warmer water temperatures.
Winds and seas should begin subsiding late Tuesday into midweek as
high pressure settles into the area. A reinforcing but much weaker
cold front is forecast to move into the waters late Thursday night
or Friday morning. Onshore flow returns to the area over the weekend
as surface high pressure behind the second front quickly moves off
to the east.
