Area Forecast Discussion
National Weather Service Houston/Galveston TX
1242 PM CDT Tue Jul 13 2021

.AVIATION [18Z TAF Issuance]...

VFR this afternoon, with scattered showers and storms. Storms fall
apart as the sun goes down, with light/VRB winds. Some clouds at
MVFR expected towards dawn - a CIG is possible, but only
explicitly in the TAF at CLL, UTS, and CXO. Rinse and repeat
tomorrow.

.PREV DISCUSSION /Issued 403 AM CDT Tue Jul 13 2021/...

SHORT TERM [Today Through Wednesday Night]...

At 200 AM, high pressure was located over the eastern Gulf of Mexico
with a light onshore wind and temperatures generally in the lower
70's. Satellite derived PW imagery shows PW values around 1.70
inches over the SW zones with a minimum value of around 1.50 inches
over the Central zones and then back to around 1.60 inches over the
NE zones. Fcst soundings don't show a lot of saturation today with
Pw values hovering between 1.70-1.80 inches by mid afternoon.
Despite soundings showing a weak cap near 850 mb, the cap looks
breakable with some heating. Convective temperatures today are
around 90 degrees so there should be a few, mainly afternoon showers
and isolated thunderstorms. 850 mb temperatures are around 20.5 -
21.5 C so MaxT values should top out in the lower and mid 90's. Any
residual precipitation should wane early this evening with generally
clear skies overnight.

850 mb temps cool by 12z Wednesday with 850 temps around 19 C.
Capping in the 850 mb looks considerably lower on Wednesday with
convective temperatures in the upper 80's. Pw values look a bit
higher and show top out between 1.90-2.00 inches so feel rain
chances will be a bit higher on Wednesday than today. Will trend
MaxT a little cooler and PoPs a bit higher for Wednesday. Will carry
some residual PoPs into the evening over the western zones but feel
activity will end quickly with the loss of heating. Skies will clear
in the evening but clouds will increase after 06z into Thursday
morning. The cloud cover should allow for warmer MinT values by
Thursday morning. 43

LONG TERM [Thursday Through Tuesday]...

The synoptic pattern for the majority of the long term will be
remaining mostly the same meaning there will not be much variance
to our weather. A weak upper level trough will be moving across
the Upper Midwest into the Great Lakes region with one center of
high pressure located over the Desert Southwest and another
located over the Southeast. While there will not be much of
driving force for precipitation in our neck of the woods, PWATs
will be remaining around 2 inches through the weekend. So between
daytime heating and the seabreeze, expect showers and
thunderstorms to pop up along the coast each afternoon. The chance
of showers will be lowest (though not completely zero) Sunday
into Monday as the upper level high pressure to the east slides
westward across Texas. Meanwhile the ridge over the Desert
Southwest strengthens and extends across much of the western half
of the US by Monday. This shifting high pressure helps to dig a
trough across the Central Plains Monday into Tuesday bringing a
broad boundary extending across East Texas. This will increase
precipitation chances across the northern third of our area
starting Tuesday and beyond.

Temperatures will be not changing much through the long term with
afternoon high temperatures in the low to mid 90s (with heat
indices in the triple digits) and overnight lows in the mid to
upper 70s inland and near 80 at the coast.

MARINE...

Looking like a rather pleasant week across the waters. Light to
moderate onshore flow will continue through the start of next week
with seas remaining around 2 to 4 feet. Isolated to scattered
showers and thunderstorms will be possible each day, mainly during
the morning and early afternoon hours. Rip current threat will
remain low through the week.
