LOW END POPS HAD BEEN ADDED AND MAINTAIN INTO THE EARLY EVENING
ACROSS PORTIONS OF THE COASTAL PLAINS WHERE ISOLATED SHOWERS AND
STORM ACTIVITY HAVE REACHED INTO PORTIONS OF KARNES, DEWITT AND
LAVACA COUNTIES. THERE IS ADDITIONAL ACTIVITY TO THE EAST TOWARD

BEFORE ENDING WITH LOSS OF DAYTIME HEATING.

- LOW TO MEDIUM CHANCES FOR AFTERNOON SHOWERS AND THUNDERSTORMS
SUNDAY THROUGH WEDNESDAY.
SHORT TERM
(TONIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 115 PM CDT SAT AUG 9 2025
HOT AND MOSTLY DRY CONDITIONS ARE EXPECTED FOR THE REST OF THE
WEEKEND AS THE SUBTROPICAL RIDGE CONTINUES ITS WESTWARD
PROGRESSION. TONIGHT, AN INVERTED TROUGH WILL MOVE OVER THE
TX COAST AND REMAIN OVER THE AREA SUNDAY. THIS FEATURE WILL
BRING SOME INCREASED MOISTURE ALLOWING FOR LOW TO MEDIUM
PRECIPITATION CHANCES FOR THE COASTAL PLAINS DURING THE
AFTERNOON. OTHERWISE, ANOTHER HOT DAY IS FORECAST WITH HIGHS IN
THE MID 90S TO AROUND 100 DEGREES. WITH THE LOSS OF HEATING
CONVECTION WILL END SUNDAY EVENING LEAVING A DRY FORECAST
OVERNIGHT. LOW TEMPERATURES WILL BE WITHIN A COUPLE OF DEGREES
OF NORMAL.
LONG TERM
(MONDAY THROUGH SATURDAY)
ISSUED AT 115 PM CDT SAT AUG 9 2025
THE INVERTED TROUGH WILL MOVE FURTHER INLAND MONDAY WHILE
ANOTHER UPPER LEVEL TROUGH MOVES ACROSS THE CENTRAL US TUESDAY
AND WEDNESDAY. DIURNAL HEATING AND SOME SUPPORT ALOFT WILL
COMBINE WITH A SURGE OF MOIST AIR FROM THE GULF SPREADING
PRECIPITATION CHANCES ACROSS NEARLY ALL OF SOUTH-CENTRAL TEXAS
EACH AFTERNOON MONDAY THROUGH WEDNESDAY. THE BEST CHANCES WILL
BE IN THE EAST OVER THE COASTAL PLAINS. THE SUBTROPICAL RIDGE
WILL BUILD BACK OVER THE REGION STARTING THURSDAY AND ANY
SHOWER OR THUNDERSTORM ACTIVITY WILL RETREAT BACK TO THE COASTAL
PLAINS FOR THE REST OF THE WEEK.
HIGH TEMPERATURES ARE FORECAST TO BE IN THE 90S TO AROUND 100
DEGREES EACH DAY NEXT WEEK WITH LOWS MAINLY IN THE 70S. HEAT
INDICES WILL CONTINUE TO BE BELOW HEAT ADVISORY CRITERIA,
GENERALLY FALLING IN THE MID 90S TO AROUND 106 DEGREE RANGE.
ALTHOUGH THESE TEMPERATURES ARE FAIRLY TYPICAL FOR THIS TIME OF
YEAR, CONTINUE TO PRACTICE HEAT SAFETY MEASURES.
