.DISCUSSION...
Issued at 1208 AM CST Sun Nov 30 2025

The cold front is currently moving southward stretched W to ENE
across the Hill Country south of San Antonio into Southeast Texas.
Latest CAM guidance shows a slightly later progression through
South Texas, mainly between 2-8 AM early this morning. Ahead of
and along the front, there is a medium to high chance of showers
and thunderstorms, with an environment marginally conducive for
strong to severe storms mainly focused over the Victoria
Crossroads. It`s been a slow and dry start of the overnight hours,
but do expect convection to increase over the next couple of
hours. There is a marginal risk of severe storms, capable of
producing large hail and damaging winds, as well as flash flooding
with high rain rate slow moving cells. Farther westward, the
environment is more capped and will struggle to tap into any
instability capable of producing strong to severe storms.

A lull in rain chances is expected in the wake of the cold front
Sunday afternoon, before medium to high rain chances return late
tonight through Monday as a surface low develops over the northwest
Gulf. The proximity of the boundary and low inducing moist
isentropic lift, in combination of a more amplified mid-level
shortwave, warrants medium to high rain chances. Rain chances
diminish once again Monday night as a reinforcing surge of high
pressure pushes through. Surface high pressure shifts eastward
thereafter, returning onshore flow Wednesday along with a coastal
trough. The coastal trough will remain intact ahead of our next cold
front passage late in the work week Thursday - Friday, allowing for
medium (40-60%) chance of showers and thunderstorms to persist until
the passage. This late week front isn`t in as good of model
agreement, nor look as strong as this morning`s, and therefore kept
low chances of showers and thunderstorms to close out the week.

Below normal temperatures are expected Sunday through Tuesday, with
highs mainly in the 50s to the lower 60s and lows in the 40s, with
the exception of early Tuesday morning in the upper 30s over
northern counties. More seasonal-like temperatures are expected
mid to late in the work week.

.AVIATION...
(12Z TAFS)
Issued at 519 AM CST Sun Nov 30 2025

The cold front will continue moving south through the region this
morning. Ahead of the front winds will be out of the S at 5-10 kts
but behind the front winds will rapidly switch to be more out of
the N at 15-20 kts gusting as high 30 kts. Rain will be scattered
in coverage with the cold front passage, but remain dry throughout
most of the day. After 06Z, rain returns to most terminals,
dropping MVFR CIGs down to IFR by the end of the TAF cycle.

.MARINE...
Issued at 1208 AM CST Sun Nov 30 2025

A fresh (BF-5) south to southeasterly breeze will quickly change
north to northeasterly and strengthen to 20-30 knots in the wake of
a cold front later this morning, mainly between 4-7 AM. There is a
marginal risk for strong to severe storms ahead of the front,
capable of large hail and damaging winds, mainly north of Port
Aransas. A Small Craft Advisory remains in effect through Sunday
night, before a moderate to fresh (BF 4-5) northerly breeze takes
over. Rain chance increase to a medium to high (50-75%) chance
tonight through Monday night. By Monday night, high pressure surges
in bringing with it drier air and reduced rain chances through
midweek. The surge of high pressure will also return a strong
northerly breeze through Tuesday morning. Onshore flow returns
briefly midweek. Medium to high chances of showers and thunderstorms
return mid-to-late in the week in association with our next frontal
system.

.FIRE WEATHER...
Issued at 1208 AM CST Sun Nov 30 2025

Minimum relative humidity will remain above 40% through this next
week along with below normal temperatures Sunday through Tuesday
following a strong cold front early this morning. Medium to high
chances for showers and thunderstorms are forecast through Monday in
association with the frontal passage as well as the formation and
subsequent stalling of a surface low off the coast. Additionally,
north-northeasterly winds will increase to 15-25 mph behind the
front. A brief lull in rain chances is expected after a reinforcing
surge of high pressure pushes through late Monday night into
Tuesday, but low to medium rain chances return Wednesday through
Friday as additional disturbances arrive. There are no elevated fire
weather concerns at this time.
