SHORT TERM
(TONIGHT THROUGH SATURDAY NIGHT)
ISSUED AT 1217 PM CDT FRI AUG 8 2025
SUMMER-LIKE TEMPERATURES CONTINUE THIS AFTERNOON AND TONIGHT AS THE
SUBTROPICAL RIDGE OVER NEW MEXICO CONTINUES TO SLOWLY LOOSEN ITS GRIP
OVER MOST OF SOUTH CENTRAL TEXAS AS IT SLIDES WESTWARD. AIR TEMPERATURES
SHOULD BE A FEW DEGREES COOLER (IN THE UPPER 90S) SATURDAY. HOWEVER, WITH
THE INCREASED MOISTURE OUR FEELS LIKE TEMPERATURES WILL BE ABOUT THE
SAME AS TODAY (100-105 RANGE). WITH THE RIDGE MOVING WESTWARD THIS
OPENS UP THE DOOR FOR COASTAL AFTERNOON SHOWERS AND THUNDERSTORMS FOR
OUR FAR EASTERN COUNTIES DUE TO THE SEABREEZE HOWEVER, EVERYWHERE
ELSE SHOULD REMAIN DRY WITH LOWS MAINLY IN THE 70S.
LONG TERM
(SUNDAY THROUGH FRIDAY)
ISSUED AT 1217 PM CDT FRI AUG 8 2025
AN INCOMING INVERTED TROUGH MAKES ITS WAY WESTWARD FROM THE
SOUTHEAST STATES ARRIVING OVER THE TEXAS COAST BY SUNDAY. THIS TROUGH
WILL BRING WITH IT HIGHER CHANCES FOR AFTERNOON COASTAL SHOWERS AND
STORMS MAINLY STAYING EAST OF THE I-35 CORRIDOR AND IN THE COASTAL
PLAINS DURING THE AFTERNOON HOURS.
LOOKING AHEAD TOWARDS EARLY NEXT WEEK, SOME GLOBAL MODELS ARE
SUGGESTING THIS INVERTED TROUGH LINGERS OFF THE TX COAST AND MOVES
NORTHWARD THROUGH OUR AREA. WE WILL HAVE TO WATCH THIS CLOSELY DUE
TO WEAK STEERING CURRENTS AS OUR AREA WILL BE SANDWICHED BETWEEN THE
WEAKENING HIGH TO OUR WEST AND A DEVELOPING HIGH IN THE SOUTHEASTERN
GULF STATES. CONTINUED CHANCES FOR AFTERNOON SHOWERS AND STORMS
RESUMES FOR THE REST OF THE PERIOD MAINLY FOR THE COASTAL PLAINS.
HOWEVER, IF THE INVERTED TROUGH GETS HUNG UP OVER OUR AREA THEN
SHOWERS AND STORMS COULD BE POSSIBLE FOR AREAS FURTHER WEST EACH
AFTERNOON THROUGH WEDNESDAY. BEYOND WEDNESDAY SHOWERS AND STORM
CHANCES RETREAT BACK TOWARD THE COASTAL PLAINS. TEMPERATURES REMAIN
SEASONABLY HOT SUNDAY THROUGH NEXT WEEK WITH HIGHS IN THE MID TO
UPPER 90S AND HEAT INDICES IN THE 100-105 RANGE WITH LOWS GENERALLY
REMAINING IN THE LOW TO MID 70S.
