.DISCUSSION...
Issued at 1205 AM CST Sat Nov 29 2025

The strong cold front we`ve been focused on the past few days
remains on track to surge through South Texas between midnight and 7
AM Sunday. Ahead of and along the front, environmental conditions
may be conducive for strong to severe storms, mainly over the
Victoria Crossroads where a marginal (level 1 of 5) severe risk is
intact. MUCAPE climbs to 1500-2000 J/kg with effective shear near 40
knots and mid-level lapse rates around 7 C/km, large hail and
damaging winds are the primary threats. The threat of high rain
rates with storms both ahead and along the front, also poses a
marginal risk of excessive rainfall over the same area.

Once the front passes, a surface low is expected to develop over the
northwest Gulf, keeping the boundary in close proximity to the Texas
Coast. This will allow for isentropic lift and mid-level PVA to
contribute additional medium to high (50-80%) chance of showers and
thunderstorms late Sunday night through Monday. A reinforcing surge
of high pressure will push through late Monday night into Tuesday
morning, diminishing rain chances significantly through Wednesday.

A surface coastal trough looks to develop ahead of the next cold
front late in the work week. Models are not in good agreement and
therefore confidence is low in timing/strength of this front.
Nonetheless, PWAT values will extend well above normal between 1.5-
2.0" and coincide with plenty of mid-level PVA downstream of a
positively tilted trough over the SW CONUS, allowing for a low to
medium chance of showers and thunderstorms late in the work week.

Below normal temperatures Sunday through Tuesday with highs in the
50s Monday and lows from the upper 30s to mid 40s. More seasonal
temperatures return late in the work week with highs back in the 60s
to lower 70s and lows from the upper 40s to around 60.

.AVIATION...
(12Z TAFS)
Issued at 456 AM CST Sat Nov 29 2025

MVFR conditions thanks to reduced CIGs are showing up throughout
South Texas, especially near the presence of this morning`s
scattered showers. This will continue through mid-morning with a
brief lull in the afternoon. CIGs then should raise to be marginal
VFR. Tonight from around 00Z, thunderstorm activity increases near
KVCT and locations to the northeast. In the vicinity of a
thunderstorm, gusty and erratic winds are possible. As the cold
front approaches the forecast area after 06Z, CIGs will drop into
MVFR/IFR territory as a line of showers and thunderstorms moves
south through the end of the TAF cycle.

.MARINE...
Issued at 1205 AM CST Sat Nov 29 2025

Southeasterly winds of 20-30 knots will continue through this
morning, before weakening slightly to fresh to strong (BF 5-6) this
afternoon. Although there will likely be a lull in Small Craft
Advisory conditions tonight, a Small Craft Advisory remains in
effect through Sunday as a strong cold front will push through early
Sunday morning and quickly return strong north to northeasterly
winds in the wake. Offshore winds fall to moderate to fresh (BF 4-5)
early next week with onshore flow returning Wednesday. Low rain
chances today will increase to a high, 60-90% chance, tonight
through Monday night. Medium to high chances of showers and
thunderstorms return mid to late next work week.

.FIRE WEATHER...
Issued at 1205 AM CST Sat Nov 29 2025

Minimum relative humidity will remain above 40% through next work
week with below normal temperatures Sunday through Tuesday following
a strong cold front early Sunday morning. Medium to high chances for
showers and thunderstorms tonight through Monday. A brief lull in
rain chances after a reinforcing surge of high pressure pushes
through late Monday night into Tuesday. Low to medium rain chances
return Wednesday through Friday. There are no elevated fire weather
concerns at this time.
