.SHORT TERM...
(Tonight through Thursday night)
Issued at 249 PM CDT Wed Sep 25 2024

A few showers and thunderstorms will develop along a southward
advancing cold front through early evening. Some of these could be
on the strong side with gusty winds being the primary hazard.
Otherwise, most locations stay dry with the exception being those
with that 20% chance south of Highway 90/I-10. Temperatures have
still managed to warm into the upper 80s to mid 90s despite the
passage of the front. North to northeasterly winds will bring in
drier air overnight, but the relatively cooler air is nowhere to be
found. Sadly, this front won`t bring significant relief in terms of
afternoon temperatures, however, it will bring much-needed cooler
and more comfortable mornings for the region both tonight and
Thursday night. Expect lows in the 50s for the Hill Country, with 60s
elsewhere by tonight and tomorrow night. Otherwise, breezy northerly
winds look to continue tomorrow with highs in the mid to upper 80s
and lower 90s.

.LONG TERM...
(Friday through Wednesday)
Issued at 249 PM CDT Wed Sep 25 2024

A mid and upper level low combined with the remnants of `Helene`
will remain anchored over the southeastern U.S. into the middle
Mississippi River valley through the end of the week. On the
backside of this low, north to northwest flow remains intact on
Friday with the medium range models showing a weak upper disturbance
dropping southward into the region into the upcoming weekend. Dry
air on the backside of this should limit any rain chances in the
long-term portion of the forecast. The dry air in the low-levels
combined with clear skies will allow for overnight lows will dip
into the mid to upper 50s over the Hill Country, with lower to mid
60s elsewhere. Daytime highs will range from the mid 80s to mid 90s,
with the warmest temperatures out west along the Rio Grande.

For the early portion of next week, the mid and upper level ridge
axis begins to build eastward into the southern U.S. plains.
Temperatures may warm slightly on Monday, with models still showing
a surge of cooler air possibly moving into the region on Tuesday.
