.DISCUSSION...
Issued at 1200 PM CST Wed Jan 14 2026

Generally near to below normal temperatures will continue through
mid week next week across Deep South Texas due to the passage of
a pair of cold fronts, with the exception being this afternoon and
Friday afternoon. Highs this afternoon will warm into the mid to
upper 70s region wide, which is 5 degrees above normal for mid
January. The first of a pair of cold fronts will reach the region
late this afternoon and evening, which will bring temperatures
slightly below normal on Thursday. Given the relatively dry
airmass ahead of this boundary, no precipitation is expected with
the frontal passage. Highs on Thursday will remain mostly in the
mid to upper 60s, although a few areas may reach 70 degrees.
Afternoon relative humidity values will range from 20-30 percent
across the region tomorrow, but wind speeds below 10 MPH should
preclude elevated fire weather concerns.

Along the Lower Texas beaches, the combination of increasing winds
and elevated seas will result in a high risk of rip currents this
evening through tomorrow evening. Additionally, a High Surf
Advisory will be in effect from 3 AM to 12 PM Thursday as surf
ranging from 6-8 feet cannot be ruled out in response to the cold
front.

Low level southerly flow briefly returns late Thursday evening
into Friday morning. This will allow for a brief warm up on
Friday, with highs in the upper 70s and perhaps a few areas
reaching 80-81 degrees. Fortunately, this warm up will be fairly
short-lived, as the second cold front will sweep across Deep
South Texas late Friday into Saturday. There are still some
discrepancies among deterministic, ensemble, and probabilistic
guidance on the frontal timing and overall evolution of the
system, so expect adjustments to the forecast over the next 48
hours. Looking ahead into early next week, a weak upper level
system may bring low (20-30%) rain chances late Monday into
Tuesday across portions of the region.

(00Z TAFS)
Issued at 515 PM CST Wed Jan 14 2026

VFR will prevail at the aerodromes through the next 24 hours,
with clear skies and breezy winds becoming light for the overnight
hours and through Thursday.

.MARINE...
Issued at 1200 PM CST Wed Jan 14 2026

Generally favorable marine conditions will continue through this
evening, but the passage of a cold front will bring Small Craft
Advisory conditions over the Gulf waters and the Laguna Madre
beginning late this evening and continuing through at least
tomorrow evening. Favorable conditions should return by Friday,
but the passage of another cold front will bring Small Craft
Advisory conditions once again this weekend. Otherwise, low rain
chances (20-30%) return on Saturday with the cold front.
