.SHORT TERM...
(Tonight through Friday night)
Issued at 150 PM CST Thu Nov 21 2024

Surface high pressure today brings clear skies and light and
variable wind over South Central Texas with mild highs in the upper
60s to mid 70s. High pressure will continue to influence the area
through the short term period with northwest flow aloft. These
conditions will keep quiet and dry weather prevailing in the short
term period. Overnight lows into Friday morning should be a few
degrees warmer than last night, mainly in the upper 30s to mid 40s.
Light easterly to southeasterly wind Friday afternoon will lend
itself to a slight uptick in afternoon highs from the low to upper
70s with some high clouds overhead. Stronger southeasterly wind
Friday night may allow for some deeper moisture and patchy clouds to
the west overnight. Lows will largely be in the 40s early Saturday
morning.

.LONG TERM...
(Saturday through Thursday)
Issued at 150 PM CST Thu Nov 21 2024

Dry and warm weather is forecast for the weekend into early next
week. Saturday`s highs are likely to range from the mid 70s to mid
80s across the southern Rio Grande. Sunday`s overnight lows are
expected to range from the 50s and 60s. Sunday`s highs are forecast
to be above normal values from the upper 70s across the Hill
Country, mid 80s along and east of Interstate 35 and even lower 90s
over some locations across the southern part of the Rio Grande.
Southerly winds are forecast to be moderate 10 to 15 mph with gusts
of 20 to 30 mph based on the national blend model guidance. Partly
cloudy skies are expected to develop overnight through the early
Monday morning period. Lows are likely to range from the 50s and 60s.

Another warm day is in store for Monday across south central Texas
with highs reaching the upper 70s to mid 80s to the lower 90s. A
cold front is forecast to push across the local area sometimes on
Monday night into Tuesday morning. A cooler airmass spreads across
the local area to bring high temperatures down to the 70s and lower
80s across the coastal Plains. The boundary pushes back to the north
into central Texas during the day on Tuesday with southerly winds
returning to south central Texas.

With southerly winds in place, Wednesday`s highs go back to the
upper 70s to the mid and upper 80s. And guess what? Another cold
front is forecast to push across the local area throughout the day
on Thursday. It is a dry front so far with the GFS solution coming
in a bit faster than the ECMWF as far as the northerly wind shift.
Thursday`s highs are forecast to range from the upper 60s across the
Hill Country to mid 70s along Interstate 35 and lower 80s across the
coastal Plains.
