.KEY MESSAGES...

- Low chance of isolated showers over the Coastal Plains Friday
afternoon/evening.

- Dry weather over the weekend into next week with elevated heat
  index values through the period

&&

.SHORT TERM...
(Tonight through Friday night)
Issued at 119 PM CDT Thu Jul 17 2025

Quiet weather conditions are forecast for the rest of today into
this evening and overnight periods. You may see scattered to broken
upper level clouds moving from east to west associated with the
tropical disturbance across the northern Gulf waters. By the way,
the latest information about this disturbance (AL93) as of 1 PM CDT,
shows a disorganized system with low chances for tropical cyclone
formation in 48 hours.

Tropical moisture is forecast to move along the Gulf coast and into
the east and middle Texas coast by Friday. The combination of the
seabreeze and this increased moisture could help isolated to
scattered showers and thunderstorms to form over portions of the
coastal plains. Other than that expect partly cloudy skies for the
eastern two-thirds of South Central Texas with highs in the upper
80s to near 100.

&&

.LONG TERM...
(Saturday through Thursday)
Issued at 119 PM CDT Thu Jul 17 2025

The weekend forecast calls for dry weather with humidity values
increasing resulting in elevated heat index values in the 100 to 107
range with a few places getting into the 108 to 109. By Monday into
Tuesday of next week, an upper level ridge takes control of the
local area for plenty of dry weather conditions and the opportunity
for a warming trend.

.AVIATION...
(18Z TAFS)
Issued at 119 PM CDT Thu Jul 17 2025

Few changes to the going forecast with VFR ceilings expected through
the period. Expect winds to remain around 7-10 kts out of the south
to southeast this afternoon before letting up somewhat this evening
after sunset. There is a low chance, about 20-40% per SREF guidance
that MVFR ceilings could develop at SAT, SSF, and AUS, particularly
SSF, but will opt for VFR ceilings for now. Winds shift to more
southeasterly by midday Friday at all sites.
