.SHORT TERM...
(Tonight through Thursday night)
Issued at 209 PM CDT Wed Sep 28 2022

Upper level high pressure system continues in control across the
Rockies and Southern Plains. At the surface, a ridge of high
pressure is forecast to dominate the local area through the short
term period. The combination of the above mentioned features will
promote sunny skies during the days and clear skies during the
nights. Light winds, clear skies and low dewpoint temperatures will
result in efficient radiational cooling. Therefore, expect another
cooler night with lows in the mid 50s across the Hill Country, lower
60s along I-35 corridor and mid 60s along the Rio Grande. For
Thursday, highs are forecast to range from the mid 80s to mid 90s.
Dry airmass stays in place across the area with dewpoints lowering a
few degrees less than those forecast for tonight. Therefore,
Thursday`s overnight lows are forecast to be even cooler with some
spots getting to the lower 50s across the Hill Country and between
the mid 50s and mid 60s elsewhere.

.LONG TERM...
(Friday through Wednesday)
Issued at 209 PM CDT Wed Sep 28 2022

A comfortable but rain free weather pattern with low humidity will
continue across South-Central Texas this weekend as another bout of
some even drier air arrives from out of the northeast by late Friday
with surface high pressure being pushed westward as Ian moves inland
into portions of Georgia/South Carolina. This drier air is expected
to keep our stretch of seasonably warm afternoons and cool mornings
going with an abundance of sunshine in the afternoon and clear skies
at night. The morning lows this weekend fall into the mid 50s over
portions of the I-35 corridor while low-lying drainage valleys could
drop into the mid to upper 40s in a few spots. Winds should remain
generally light from out of the northeast to east-northeast.

Rain free conditions are likely to continue through early to middle
of next week with a very gradual recovery in dew points once surface
winds become more easterly compared to northeasterly. Temperatures
will otherwise remain near seasonal averages. Latest model guidance
continues to show some considerable disagreement on the evolution of
invest 97E in the Eastern Pacific. The latest GFS continues to show
that this disturbance could potentially hook into the Southern Baja
California peninsula near Cabo San Lucas before reaching and quickly
dissipating into mainland Mexico for early next week. Whereas other
model solutions indicate that this system could continue westward
across the Pacific basin with little to no impact to Mexico. If the
storm does impact and dissipate into Mexico, then we can anticipate
at least some increased cloudiness across the region from out of the
west. While the rainfall chances still look quite unlikely in this
scenario, virga and/or very light sprinkles may be possible embedded
within any thicker mid to high level cloud cover.

.AVIATION...
(00Z TAFS)
Issued at 636 PM CDT Wed Sep 28 2022

VFR conditions under clear skies through the TAF period. Winds will
become calm to variable at less than 5KT after sunset. After 15Z
Thursday, I-35 terminals will see E/NE winds turning E/SE late in the
day. DRT will continue their typical SE or SSE wind directions.
Midday winds should be mostly near 10 knots or below, but a few gusts
to 18 knots or more are possible during the warmest part of the day.
