.DISCUSSION...
Issued at 1156 PM CDT Sun Mar 15 2026

The cold front is currently about to exit the offshore Gulf
waters and strong northerly winds are starting to ramp up over
Southeast TX. We are observing winds at 20-25 with gusts of 30-40
mph inland. These speeds are expected to prevail into the morning
hours as a 50-60 knot low level jet moves overhead behind the
frontal passage tonight. The Wind Advisory will continue in effect
through 6 PM Monday. Make sure loose and light outdoor objects
have been secured. Strong winds could also lead to power outages
at times. Cold, dry air will also move in quickly behind the front
tonight, with temperatures dropping into the upper 30s to mid 40s
by sunrise. Taking into account the strong northerly winds,
temperatures will feel closer to the upper 20s to mid 30s. Thus,
make sure to bundle up during the early morning hours.

Colder conditions prevail Monday, with sunny skies and highs in
the 50s areawide. Very nice :P. The one thing we will have to
monitor closely on Monday is the potential for elevated to
critical fire weather conditions given how dry and windy we will
be (more details on the Fire Weather Discussion below). Winds
begin to relax by late afternoon to evening.

CAA will continue on Monday night and will give us the coldest
temperatures for this week. The lows will be in the lower 30s
(near freezing) over the Piney Woods, the mid 30s to lower 40s for
the rest of the inland portions, and the mid to upper 40s along
the coasts. Fair weather will prevail for the rest of the work
week. Southerly flow will return Tuesday and continue into the
rest of the work week, resulting in another warming trend with
highs will be back in the 80s by Thursday and the upper 80s to
lower 90s this weekend.

.AVIATION...
(00Z TAF Issuance)
Issued at 607 PM CDT Sun Mar 15 2026

A broken line of thunderstorms is quickly moving through the area
this evening along a cold front. Strong northerly winds should
develop in the wake of the front with gusts approaching 40-50
knots. Even if the strongest gusts aren`t mixing down, vertical
wind shear will be present to a degree with northerly winds of
40-45 knots around 2,000 ft. Winds should ease down slightly
overnight, generally 18-23 knots prevailing with gusts up to
around 30-35. Winds at KGLS will take more time to taper down.
Overall strong northerly winds and VFR conditions should prevail
into Monday and through the remainder of the TAF period.

.FIRE WEATHER...
Issued at 1156 PM CDT Sun Mar 15 2026

Very dry air will filter across Southeast TX in the wake of
Sunday`s front. Expect elevated to critical fire weather
conditions as afternoon RH values lower into the upper teens to
lower 20s on Monday and northerly winds are around 20-25 mph with
gusts of 25 to 35 mph. A Fire Weather Watch will be in effect for
most of Southeast TX on Monday. Dry conditions prevail on
Tuesday, but winds will veer southeasterly and be much lighter. RH
values will begin to increase mid week into the end of the work
week as south-southeasterly winds prevail and low level moisture
recovers.
