.SHORT TERM...
(This evening through Tuesday Night)
Issued at 144 PM CST Mon Jan 13 2025

Fairly quiet weather is expected through tomorrow as high
pressure remains situated just to the north. Mostly clear skies
and breezy northeasterly winds will persist through the day today.
Cloud cover does begin to increase through beginning Tuesday
afternoon or evening as yet another coastal low begins to slide up
through the west-central Gulf. This disturbance may lead to some
isolated light rain showers along the coast late Tuesday night,
then increasing in coverage on Wednesday (but more on that in the
Long Term below).

High temperatures today and Tuesday will be in the mid to upper
50s. Overnight low temperatures tonight will get down into the mid
30s to low 40s for most of the area - but near freezing
temperatures are likely in the Piney Woods. Low temperatures
Tuesday night will rise around 5 to 10 degrees thanks to the
increased cloud cover with most of the region staying in the 40s:
low 40s to the north, mid to upper 40s down to the coast.

.LONG TERM...
(Wednesday through next Sunday)
Issued at 144 PM CST Mon Jan 13 2025

Look for increasing rain chances during the day on Wednesday and
Wednesday night as a coastal low develops over the Western Gulf of
Mexico, bringing an increase in low level moisture while a mid to
upper level trough moves across the Southern Plains. Due to
mostly the rainfall and cloudy skies, the highs on Wednesday will
be slightly cooler, with most of Southeast TX possibly seeing
highs in the low 50s. The coastal low is expected to track east
and move into the central Gulf waters Thursday. As it does so,
drier air will move into our local area, high pressure will build
over TX, and we will see a decrease in rain chances.

WAA increases Friday into Saturday as southerly flow quickly returns
and pushes in warm moist air from the Gulf. We may be seeing highs
in the mid to upper 60s for many locations on both days. Rain
chances are expected to return Friday and continue into Friday
night. Friday night into Saturday morning, an upper level trough is
expected to move across the Southern Plains and an associated cold
front will race across TX, possibly moving through Southeast TX
during the morning hours. A dry cold airmass will quickly spread
across the region in the wake of the front later on Saturday. Make
sure to bundle up, because we might see a 30 degree drop in
temperatures overnight Saturday. By sunrise, temperatures could be
in the 30s for most of the local area. CAA will continue on Sunday
night, resulting in even colder conditions with lows near or below
freezing for much of the region.

VFR conditions prevailing through the period. Winds will be light

.MARINE...
Issued at 144 PM CST Mon Jan 13 2025

Moderate to occasionally strong northeast to east winds and seas
generally between 3 to 6 feet are expected through Thursday. For
the bays, some spots could see low water levels during low tide.
Onshore flow will briefly return Friday, turning southwesterly
Friday night ahead of the next cold front. The front is forecast
to move across Southeast TX on Saturday, possibly reaching the
coast by late morning or early afternoon. Strong offshore winds
and elevated seas will develop in the wake of the front. In
general, Caution Flags and Advisories will continue throughout
much of the forecast period. In addition, expect periods of
showers mid week through the upcoming weekend.
