.SHORT TERM...
(Tonight through Wednesday night)
Issued at 1203 PM CST Tue Nov 11 2025
Light west-northwesterly flow is noted on regional water vapor
imagery early this afternoon. Very dry air is noted on the 12Z
sounding at DRT and that is clearly depicted on satellite imagery
this afternoon. Surface RH values will fall to between 15-25%, and
in combination with S to SSW winds of 10-20 mph and gusts up to 30
mph, critical fire weather conditions will continue through the
early evening hours. Temperatures should respond/warm rather
quickly given southerly flow and dry air, with highs topping out
in the lower to middle 70s.
Tonight, a rapid increase in surface moisture is expected as
southeasterly return flow ramps up and surface dewpoints climb
from the 20s/30s to the 40s/50s Wednesday morning. With the
increasing moisture, it won`t be nearly as chilly tonight, as
temperatures fall into mid 40s to mid 50s. Afternoon highs on
Wednesday will be quite warm after a chilly couple of days to
end the weekend and start the work week. Most, if not everyone
will warm into the lower to middle 80s Wednesday afternoon with
plenty of sunshine and comfortable humidity.

.LONG TERM...
(Thursday through next Tuesday)
Issued at 1203 PM CST Tue Nov 11 2025
The longwave pattern remains rather benign through the remainder
of the work week with mild mornings and warm afternoons continuing
through Friday. This weekend, a surface low will develop over the
Panhandle, increasing southeasterly flow over eastern and central
Texas. Our next trough approaches late Saturday into early Sunday,
but models differ on the strength of this trough and how far south
it will move. The further south it moves, the better the rain
chances. For now, PoPs remain low, between 20-40%, as we await
better model agreement on the placement of the trough.
After this system, we look towards the middle to end of next week
for the next shot at rain and storms and the CPC has issued a low
to moderate risk for heavy rain for the eastern half of our area
November 20-21st with another trough that looks a bit more
promising for precipitation. This is still 10 days out, so we will
have to give it some time before confidence can increase in much
needed rainfall.

.AVIATION...
(18Z TAFS)
Issued at 1203 PM CST Tue Nov 11 2025
VFR conditions are forecast for the local area
terminals through Wednesday evening. Breezy and gusty southerly
winds are in control for the rest of this afternoon. Then, the
southerly flow diminishes to 10 knots of less this evening into
Wednesday morning. By Wednesday afternoon, the southerly flow picks
up again with breezy and gusty conditions.
&&
.FIRE WEATHER...
Issued at 1203 PM CST Tue Nov 11 2025
A Red Flag Warning is in effect through 6pm this evening for all
of South Central Texas. With south to southwesterly flow picking
up this afternoon at 10-20 mph along with gusts up to 30 mph, and
minimum relative humidities falling to 15-25%, critical fire
weather is expected through the late afternoon/early evening. Any
fire weather concerns should rapidly decrease after sunset as
winds relax and surface dewpoints rapidly rise back into the 40s
and 50s after midnight as southeasterly return flow increases.
This will result in a warmer day Wednesday along with no fire
weather concerns.
