.SHORT TERM...
(Tonight through Monday night)
Issued at 1149 PM CDT Sat Apr 4 2026

Showers and storms beginning to weaken this morning causing the
severe storm risk to lower. The cold front is currently from
Natchez to Alexadria then down into SE TX with sh/ts well ahead of
it. This activity will slowly sink to the coast today with some
lingering showers at the coast by sunset. Everyone should get some
rainfall today that has been much needed. A sfc low will get
organized along the thermal gradient near Brownsville this morning
and start to move east. The sfc front will be well out over the
gulf by Monday but the sfc low will sling a lot of moisture over
this shallow isentropic boundary to keep the cloud cover in
through Monday. High pressure will continue to slowly press south
through the day Monday sending the cloud cover into the gulf by
Monday night or Tue. Highs today and Monday will be brought back
to around 70F with a bit of a chill to the lows in the lower 50s
and even some upper 40s north tonight and Monday night.

.LONG TERM...
(Tuesday night through Saturday night)
Issued at 1149 PM CDT Sat Apr 4 2026

The biggest concern in the long term will be a continued threat of at
least minor coastal flooding due to a spring tide cycle combined with
persistent east to southeasterly winds. Though it`s too soon to say
exactly how high water levels may rise before high tides start
lowering, those who live in low lying coastal areas should continue to
monitor the forecast.

Otherwise, a continued gradual warming trend and a return to much
warmer than normal temperatures can be expected to end the work week.
Afternoon temperatures will warm into the low to mid 80s by Saturday,
which is about 10 degrees above normal for this time of year. Morning
lows will be similarly anomalous, only cooling into the low to mid 60s
by Saturday morning.

Regarding rain chances, latest trends have been toward a slightly
wetter forecast, especially Wednesday night through Thursday night as
moisture streams northward in response to a weak mid level disturbance
lifting from northern Mexico toward the Great Lakes region. Still quite
a bit of spread in the ensembles regarding where the best moisture
convergence will be, and thus, where the greatest rain chances will be.
Current forecast calls for best rain chances to be west of the local
area with generally isolated coverage locally. However, these values
could be adjusted upward if disturbance is a little slower to lift
northward.

.AVIATION...
(12Z TAFS)
Issued at 543 AM CDT Sun Apr 5 2026

A mix of IFR and MVFR cigs will lift to VFR by noon today. There
will remain a high chance of SHRA with isolated TSRA through the
afternoon hours which could cause some tempo IFR conditions. Cigs
will be over the area all day and most of tonight but should be in
MVFR to VFR range by mid to late afternoon. All of the sh/ts
activity should move to the coast by sunset today with only
showers lingering near coastal terminals. Fropa will bring
norherly winds to the area today and this will be timed in the
current taf package.

.MARINE...
Issued at 1149 PM CDT Sat Apr 4 2026

Southeast winds around 15 knots and seas of 2 to 4 feet will
lower today as a cold front approaches the coastal waters. Behind
the front, north to northeast winds will increase to 20 to 25 knots
for most waters, and Small Craft Advisories have been posted for
this Sunday night through Monday. Northeast winds will start the
week and slowly become easterly through the week remaining moderate
to high, ranging from 15 to 30kt, through much of the week bringing
hazardous marine conditions and headlines for much of the week.
