.SHORT TERM...
(Tonight through Friday night)
Issued at 106 PM CDT Thu Apr 24 2025

Upper level ridging looks to build across the Southern Plains
through the short term period, support broad subsidence across the
area. Sustained southeasterly low level flow will continue to advect
warm and humid air to the region. This pattern will allow for
increased cloud cover overnight tonight and Friday night as
overnight cooling and light to moderate winds support the
development of some low stratus. Cloud cover is expected to
dissipate during the day Friday, with mostly sunny skies Friday
afternoon. Rain chances are expected to remain near zero through the
period. Low temperatures are expected to be in the low to mid 70s
tonight and Friday night, while high temperatures Friday afternoon
are expected to reach the upper 80s to low 90s.

.LONG TERM...
(Saturday through next Thursday)
Issued at 106 PM CDT Thu Apr 24 2025

The subtropical ridge gradually drifts south into mid next week as
multiple troughs swing into the Southern Plains. This will
maintain southwesterly flow aloft and generally dry conditions
across Deep South Texas through Tuesday, with near to slightly
above normal temperatures. Shortwaves Wednesday and Thursday
enhance lift and instability, bringing a low 20 percent chance of
thunderstorms, mainly across the northern ranchlands. Expect
breezy to windy conditions each afternoon.

Issued at 102 AM CDT Fri Apr 25 2025

MVFR ceilings will persist through the early to mid morning hours
at all TAF sites. VFR should return by mid morning and persist
through the late evening before another round of MVFR ceilings
develop once again. Southeast winds will continue through the

knots.

Issued at 106 PM CDT Thu Apr 24 2025

Tonight through Friday night...Generally favorable marine
conditions are expected through much of the period, however Small
Craft Should Exercise caution headlines may be needed for the
Laguna Madre this evening. Wind speeds are expected to decrease
overnight, though they may briefly exceed 15 kts over portions of
the Laguna Madre Friday, possibly requiring additional Small Craft
Should Exercise Caution headlines.

Saturday through Thursday...Moderate to fresh southeasterly winds
continue into late next week, with SCEC conditions likely across
the bay nearly every afternoon. Seas are expected to gradually
build, reaching SCEC conditions next week.
