.SHORT TERM...
(Today through Tuesday)
Issued at 203 AM CST Mon Dec 30 2024
Key Messages...
-Red Flag Warning this afternoon for the southern Edwards Plateau,
and western Hill Country due to gusty west to southwest winds and
low relative humidity.
Developing low pressure in the Central Plains will increase the
pressure gradient over South Central Texas today. This will result
in gusty winds and low relative humidity, especially across the NW
half of the area. Afternoon highs will be nearly 20F above normal,
resulting in many daily maximum temperature records being tied or
broken for December 30th. Overnight lows tonight will be near to
slightly above normal, mainly due to elevated wind speeds from the
newly arrived front. With sunny skies and a somewhat low amplitude
upper trough pulling away from TX, Tuesday max temps will also fall
into the near to above normal value range due to the weakness of the
front.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 203 AM CST Mon Dec 30 2024
Key Messages...
- Cooler conditions for New Year`s Eve with temperatures in the lower
40s to lower 50s at midnight. Overnight lows in the mid 30s to mid
40s.
- New Year`s Day highs in the upper 50s to mid 60s.
- Slight warmup trend is forecast for the latter part of the work
week with temperatures back into the upper 60s and mid 70s by
Sunday.
- A cold weather pattern is forecast for next Monday and the rest of
the week.
In the wake of the cold front, a cooler airmass spreads across South
Central Texas to begin the 2025. Temperatures are forecast to range
from the lower 40s to lower 50s to welcome 2025. Much cooler
temperatures are forecast for the overnight hours and down to the
mid 30s across the Hill Country.
New Year`s Day highs are forecast to reach the upper 50s to mid 60s
under partly cloudy skies. Clouds increase during the evening into
Thursday morning with overnight lows in the upper 30s to upper 40s.
The cooler airmass stays across the local area for the latter part
of the week into Saturday. By Sunday, an upper level short wave
moves across the Southern Plains while at the surface, a cold front
pushes across the local area. Increased moisture is likely in place
ahead of the frontal boundary allowing temperatures to go up into
the upper 60s to mid 70s. A few showers may impact areas east of
Highway 77 but confidence is low at this time.
Global models including ensemble solutions are suggesting a cold
weather pattern for the beginning of next work week with lows in the
30s and highs in the 50s for the most part.
