.SHORT TERM...
(Tonight through Friday night)
Issued at 114 PM CDT Thu Apr 30 2026

Latest visible imagery shows cloudy skies across most of South
Central Texas with some breaks over the Coastal Plains. A mid to
upper level shortwave moving across the Hill Country is helping
shower and thunderstorm activity across the Hill Country especially
over portions of Burnet, Blanco, and soon over Travis counties as
of 1 PM CDT. This activity could be enhanced as the afternoon
progresses with more activity expanding over parts of the southern
Edwards Plateau. Main hazards are large hail, strong to damaging
wind gusts, and localized heavy rain. We may have a lull in
activity later this afternoon into the early evening, but showers
and thunderstorms return over the Rio Grande mid to late evening
and then move eastward overnight into Friday afternoon and
possibly through early Friday evening. These storms will have the
support of an upper level short wave pushing from Baja California
into northern Mexico into west Texas and then over our local area
throughout the day Friday. There is a moderate to high confidence
on locally heavy rain across a good portion of South Central Texas
late this evening through Friday evening as several rounds of
heavy rain affect the local area. A Flood Watch is in effect from
9 PM CDT this evening through 9 PM CDT Friday. Rainfall amounts of
2 to 4 inches are forecast with isolated 6 inches for the
duration of the Flood Watch. Remember to promote the following:
Stay weather aware and away from flooded areas. As the wave moves
to the east of the local area Friday afternoon through the
evening, rain chances come to an end from west to east. Breezy
north winds are forecast to prevail late Friday afternoon through
the overnight hours with gusts of 30 to 40 mph.

&&

.LONG TERM...
(Saturday through next Thursday)
Issued at 114 PM CDT Thu Apr 30 2026

By Saturday morning, dry and cooler weather conditions are in store
as a surge of cooler airmass pushes from the north resulting in lows
around the mid 40s over the Hill Country to mid 50s across the
Coastal Plains. Saturday's highs are forecast to range from the
upper 60s to mid 70s. A surface high pressure system over South
Central Texas Saturday evening pushes to the east overnight into
Sunday and brings back a southerly flow to the local area. With the
return flow in place, a warming trend begins on Sunday with forecast
highs in the mid to upper 70s to low 80s along the Rio Grande.
The warming trend and dry weather conditions continue at least
through next Wednesday.
