Tomorrow marks the first day of Astronomical Autumn! We will start
the next season off with another day of showers and thunderstorms
(though, PWATs are coming in a bit lower than initially
predicted). With lower PWAT values, not expecting coverage to be
as scattered, and coverage should mainly be along the coastal
counties; however any outflow boundaries along with the sea breeze
could create opportunities for storm development further inland
during the afternoon hours Sunday. Going into next week, moisture
does begin to increase as do the rain chances, particularly around
midweek. Models continue to show the potential for a midweek cold
front (looking like sometime Wednesday/Thursday). The FROPA could usher
in some drier and cooler air near the end of the week(yes,
please!).
Temperatures through midweek will be on the warmer side with highs
in the 80s to 80s and lows in the 70s. There is some uncertainty
with how the temperatures will respond to the midweek cold front.
There is a medium to high probability of temperatures dipping
below 70s degrees Wednesday during the nighttime hours for the
Metro through the Piney Woods and Brazos Valley. For the Coastal
locations...not looking likely (less than 10% chance).
As for daytime temperatures, there are similar probabilities that
the above locations will experience highs below 90 degrees
beginning Wednesday. This excludes the coastal areas which have
been observing temperatures in the 80s even without the impacts
from a frontal system.
While still not a "for certain" forecast, it is at least some
glimmer of hope for us cold weather folks that summer is coming to
a close and fall weather is on the horizon.

(00Z TAF Issuance)
Issued at 619 PM CDT Sat Sep 20 2025
Lingering isolated shra/tstm activity should dissipate in the next
few hours with the loss of heating. Like last night, light winds
may lead to some spotty fog development across parts of the region
overnight at non-metro sites. Locally, SREF seems to favor
CLL/UTS/CXO in the 9-13z timeframe. Closer to the coast and
offshore, we`ll probably see some sct tstms develop toward
morning...possibly intermittently impacting terminals from Hobby
southward into the late morning or noontime period. This will be
covered with some PROB30`s and/or TEMPOS in the TAFs. Further
north, only isolated late afternoon precip is anticipated (if at
all). 47

.MARINE...
Issued at 1113 PM CDT Sat Sep 20 2025
No major changes to the forecast to note. Light to occasionally
moderate southeasterly winds and 2 to 4 foot seas will prevail
going into early next week. Winds become southwesterly to westerly
around midweek as a frontal boundary approaches. Northerly flow
is expected towards the end of the work week. Chances for showers
and storms prevail through at least midweek.
Mariners should be advised that a couple of waterspouts were
reported earlier today (Saturday) in Galveston Bay. Model
guidance depicts some potential for showers/storms paralleling the
coastline as early as Sunday morning, so the waterspout potential
carries on into Sunday.
