.SHORT TERM...
(Tonight through Thursday night)
Issued at 1206 PM CST Tue Jan 13 2026

High pressure extends across the southeast CONUS with light winds
at the surface. Aloft, our flow is mainly zonal with a 500mb low
pressure located to our west, over Texas. As the low-pressure
system moves closer to our area, sky cover will increase, and we
could see a few light showers in the evening and overnight. As the
disturbance moves across our region, its associated cold front
will bring a surge of dry, cold air to the region. With no
moisture return ahead of the front, rain chances will be very low,
around 10%, with no measurable rain expected. Forecast soundings
along with ensemble tables show a very dry environment behind the
front, with ensemble tables showing moisture values below the 10th
percentile aloft and RH values dropping below 30%. PWAT values
are also very low dropping below the 5th percentile.


The extended forecast will remain on the cooler side as post-
frontal high pressure builds overhead, keeping winds light and
variable.

.LONG TERM...
(Friday through next Monday)
Issued at 1206 PM CST Tue Jan 13 2026

A short period of warm air advection and moisture return will
occur on Friday before the next cold front moves through the
region on Saturday. Similar to the previous front, this will be a
dry cold front with rain chances near zero. Low temperatures will
drop below freezing in central Louisiana and parts of southeast
Texas and reach the 30s farther south.

.AVIATION...
(18Z TAFS)
Issued at 1206 PM CST Tue Jan 13 2026

VFR conditions will continue for the rest of the forecast period.
Winds will be light to calm with a high cloud deck. Light showers

.MARINE...
Issued at 1206 PM CST Tue Jan 13 2026

Surface high pressure and upper-level ridging will keep conditions
calm with winds below 10 knots and seas below 3 feet. After the
passage of a cold front on Wednesday, winds will be offshore and
will rapidly increase, and a Small Craft Advisory will be in
effect starting Wednesday morning for the coastal waters, then the
lakes and bays by Wednesday afternoon. Winds will peak near 30
knots on Thursday, and a Low Water Advisory may be needed during
low tide. Waves will build in response to the winds, building to 7
feet. Winds will begin to weaken Thursday evening and will become
light and onshore on Friday.

&&

.FIRE WEATHER...
Issued at 1206 PM CST Tue Jan 13 2026

A dry cold front moving across the region on Wednesday will create
concerning fire weather conditions, and a Fire Danger Statement is
in effect for Wednesday. The rest of the week will have elevated
fire weather concerns as RH values will be in the 20 to 40 percent
range starting on Thursday and staying that low through the
weekend. A second dry cold front on Friday will bring another
surge of north winds, and a Red Flag Warning may be needed.
