SHORT TERM
(TONIGHT THROUGH THURSDAY NIGHT)
ISSUED AT 110 PM CDT WED AUG 5 2026
LOW TO MID LEVEL CLOUDS ARE LINGERING AROUND THROUGH EARLY THIS
AFTERNOON. HOWEVER, LATEST SATELLITE IMAGES ARE SHOWING SMALL BREAKS
IN CLOUD COVERAGE, ESPECIALLY ALONG THE I-35 CORRIDOR. OUT WEST
ACROSS THE RIO GRANDE PLAINS AND PORTIONS OF THE SOUTHERN EDWARDS
PLATEAU, CLOUDS ARE STILL ABUNDANT, HOWEVER, THE FORECAST CALLS FOR
THOSE CLOUDS TO BURN OFF FOR THE MOST PART IN THE NEXT FEW HOURS.
ARE WE CALLING FOR DRY CONDITIONS FOR THE REST OF TODAY? YES AND NO.
YES, BECAUSE MOST OF SOUTH CENTRAL TEXAS IS LIKELY TO STAY DRY. THE
NO PART, IS BECAUSE AN ISOLATED SHOWER OR TWO OR AN ISOLATED STORM
OR TWO COULD DEVELOP THIS AFTERNOON ACROSS PORTIONS OF THE COASTAL
PLAINS AND THE RIO GRANDE AREA. AS A MATTER OF FACT, A QUICK SHOWER
FORMED OVER GOLIAD COUNTY AROUND 11 AM CDT (CRP CWA) AND THEN MOVED
OVER KARNES COUNTY AT THE TOP OF THE HOUR. OTHERWISE, HOT WITH HIGHS
IN THE 90S FOR MOST AREAS AND UP TO 103 DEGREES ACROSS THE SOUTHERN
PART OF THE RIO GRANDE PLAINS. ELEVATED HEAT INDEX VALUES ARE
FORECAST FOR MOST OF SOUTH CENTRAL TEXAS THIS AFTERNOON ESPECIALLY
THE COASTAL PLAINS, WHERE A FEW LOCATIONS COULD HIT THE 108 TO 112
FOR AN HOUR OR TWO.
CLOUDS REDEVELOP TONIGHT INTO THURSDAY MORNING WITH OVERNIGHT LOWS
RANGING FROM THE LOW TO MID 70S AREAWIDE. LIKE TODAY, CLOUDS STAY
UNTIL LATE MORNING OR EARLY AFTERNOON FOLLOWED BY BREAKS RESULTING
IN PARTLY CLOUDY TO MOSTLY SUNNY SKIES. WITH INCREASED MOISTURE
ARRIVING FROM THE GULF, WE ARE EXPECTING FOR THE SEABREEZE TO
PROVIDE ENOUGH LIFT TO CREATE ISOLATED SHOWER ACTIVITY INCLUDING
THE POSSIBILITY FOR A STORM OR TWO IN THE AFTERNOON. HIGH
TEMPERATURES REACHING THE 90S FOR MOST LOCATIONS AND EVEN HOTTER
ACROSS THE SOUTHERN PART OF THE RIO GRANDE PLAINS.
LONG TERM
(FRIDAY THROUGH NEXT WEDNESDAY)
ISSUED AT 110 PM CDT WED AUG 5 2026
SIMILAR WEATHER CONDITIONS OF THOSE IN THE SHORT TERM TIME FRAME ARE
FORECAST FOR THE EXTENDED PERIOD WHICH INCLUDES THE WEEKEND INTO
EARLY NEXT WEEK. THE SUBTROPICAL RIDGE CONTINUES TO DOMINATE THE
LOCAL AREA WEATHER PATTERN FOR THE NEXT WEEK WITH SURFACE
SOUTHERLY FLOW BRINGING INCREASED MOISTURE TO ACTIVATE SEABREEZE
SHOWER/STORM ACTIVITY ACROSS PORTIONS OF THE I-35 CORRIDOR AND THE
COASTAL PLAINS EACH AFTERNOON. HIGHS IN THE 90S FOR THE MOST PART
WITH OVERNIGHT LOWS IN THE 70S.
AVIATION
(18Z TAFS)
ISSUED AT 110 PM CDT WED AUG 5 2026
MVFR CIGS CONTINUE TO LIFT AND SCATTER AT THIS HOUR, AND A REPEAT
TREND IS EXPECTED THURSDAY MORNING WITH MVFR STRATUS IMPACTING ALL
AIRPORTS FOR A FEW HOURS. OTHERWISE, OCCASIONALLY BREEZY WINDS THIS
AFTERNOON WILL NOT BE AS STRONG THURSDAY AFTERNOON.
ISOLATED SHOWER ACTIVITY IS EXPECTED ACROSS THE REGION THROUGH
SUNSET THIS AFTERNOON AND EVENING, BUT COVERAGE IS NOT ENOUGH TO
INCLUDE A MENTION ON THE TAF.
