.SHORT TERM...
(Tonight through Saturday night)
Issued at 1213 PM CDT Fri Jun 27 2025

Partly cloudy skies can be detected by visible satellite photos across
the eastern two-thirds of South Central Texas early this afternoon.
Area Doppler radars are showing light shower activity across the
southern part of Lavaca County and a few thunderstorms to the south
over Corpus Christi CWA. This activity could push to the north with
the aid of the seabreeze during the next several hours to affect
a greater portion of the coastal plains area but staying to the south
of the I-35 corridor. Hires models suggest very isolated shower
activity just to the south of the I-35 corridor between 3 pm and 6
pm. Therefore, expect dry conditions for most of the period with low
probability of seeing a passing shower or storm for a short
period of time. Otherwise, highs are expected to reach the lower
to mid 90s over most places with upper 90s into 100 along the Rio
Grande.

Mostly clear to partly cloudy skies are forecasted for tonight into
Saturday with overnight lows in the 70s. Clouds are likely to burn
off by mid morning with mostly sunny to partly cloudy skies expected
for the afternoon. Drier airmass should be in place and therefore,
expect dry conditions for most places with a slight chance of a
shower or two or a storm over Lavaca County or nearby locations.

Saturday evening starts with a dry airmass, however, as the night
progresses, increased moisture arrives across the coastal plains as a
tropical disturbance over the southwest Gulf waters moves to the
northwest over the Bay of Campeche.

.LONG TERM...
(Sunday through Friday)
Issued at 1213 PM CDT Fri Jun 27 2025

Chances of showers and thunderstorms are forecasted for areas along
and south of the I-35 corridor on Sunday as increased tropical
moisture arrives across the middle Texas coast and moves inland. By
Sunday night, moisture pushes to the north and a dry and dusty
airmass spreads across most of the local area associated with a
Saharan Dust episode. Can`t rule out some hazy skies as early
Saturday night into Sunday, but the better dust signal looks to be
for Sunday into Monday and continues into mid week. Low chances for
showers and storms are forecasted for early next week mainly across
the coastal plains area and then over the Rio Grande on Wednesday
and again over most areas on Thursday. A new wave of Saharan dust
could arrive across the local area next Friday (fourth of July) into
the weekend with a warming trend in store with highs reaching the 100
mark for several places from next Sunday and beyond.

.AVIATION...
(00Z TAFS)
Issued at 640 PM CDT Fri Jun 27 2025

Now that afternoon convection has remained at a good distance from
the I-35 terminals, a more persistence trend on overnight clouds and
diurnal wind changes can be assumed. Some gusty breezes to around
20 knots are possible at any site over the next 2-4 hours with
a general trend toward fewer breezes expected by around 04Z.
Overnight stratus should reach SAT/SSF in the 06-08Z time frame and
the AUS vcnty in the 07-10Z time frame. No low cigs are expected at
DRT based on blended guidance and the trend from this morning.
