.SHORT TERM...
(Tonight through Saturday night)
Issued at 149 PM CDT Fri May 9 2025

Latest satellite imagery shows increasing cumulus clouds across
South Central Texas. Some of these clouds are showing some sort of
elevation that could end up in a shower or even a thunderstorm at
any time within the next hour. The atmosphere stays very similar
through early evening with the possibility of a stray shower or two
or an isolated thunder across the Hill Country and vicinity. There
is a slight chance for a shower or two along the Rio Grande through
the period. Breezy northerly winds stay through early this evening
and then dropping to 10 mph or less late tonight to the overnight
into Saturday morning. Overnight lows are forecasted to range from
the mid to upper 50s across the Hill Country to lower 60s across the
rest of the local area.

Saturday morning starts with mostly sunny skies across most of the
local area. By mid to late morning, clouds begin to build as wrap
around moisture arrives for most of the local area due to an upper
level low pressure circulation over Arkansas/Louisiana. There will
be enough instability along and east of Highway 281 for the
possibility of an isolated shower or two or a thunderstorm late
morning into the afternoon. Saturday`s highs will be cool ranging
from the upper 70s over the Hill Country to near 90s along the Rio
Grande. Most of the evening should by clear to partly cloudy skies
across the Hill Country. Increased moisture arrives from the
northeast late into the overnight period. Overnight lows in the
lower 50s across the southern Edwards Plateau to upper 50s along the
Coastal Plains.

(Sunday through Friday)
Issued at 149 PM CDT Fri May 9 2025

Key Message:

- Increasing temperatures may bring heat-related impacts next week.

A slow moving upper low will be located over Louisiana Sunday,
eventually shifting east Sunday night into Monday allowing ridging
to build over the area next week. Sunday will be the last day with
seasonable high temperatures before a steep warm up is seen by mid-
week. Moderate southerly flow Monday through late week will allow
temperatures to rise into the 90s to over 100 degrees by Wednesday.
Highs peak on Wednesday with only a slight reduction in temperatures
for Thursday and Friday. Record daily high temperatures may be
reached as well mid to late week across the area. Moderate HeatRisk
is expected across almost all of the area Wednesday with major
HeatRisk in the west by Thursday. Those without effective cooling or
adequate hydration should plan for these hot temperatures and make
any arrangements to stay safe. With lows in the 70s mid to late week,
little reprieve from the heat is expected overnight. Dry weather
continues through the period.
