THE SUBTROPICAL RIDGE REMAINS CENTERED OVER NEW MEXICO TODAY AND
FRIDAY. SUBSIDENCE UNDERNEATH THE RIDGE ALONG WITH A DRYING AIRMASS
KEEP RAIN OUT OF THE FORECAST. HOWEVER, CANNOT RULE OUT A SHOWER OR
TWO OVER LAVACA COUNTY EACH AFTERNOON WITH THE SEABREEZE. SEASONABLE
TEMPERATURES AND HEAT INDICES CONTINUE.
LONG TERM
(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 110 AM CDT THU AUG 7 2025
AN UPPER LEVEL TROUGH MOVING TO THE EAST OVER THE NORTHERN PLAINS
AND AN INVERTED TROUGH OVER THE NORTHWESTERN GULF WEAKEN THE RIDGE
THIS WEEKEND. SUBSIDENCE WEAKENS WHILE A MOISTER AIRMASS RETURNS TO
OUR EASTERN AREAS. THIS LEADS TO SLIGHT CHANCES OF AFTERNOON SHOWERS
AND THUNDERSTORMS EAST OF I-35 MAINLY NEAR THE COASTAL PLAINS DUE TO
HEATING AND THE SEABREEZE ON SATURDAY AND SUNDAY. THE INFLUENCE OF
THE RIDGE OVER OUR AREA WEAKENS FURTHER EARLY TO MIDDLE OF NEXT WEEK
AS THE INVERTED TROUGH CONTINUES TO DRIFT TO THE WEST WHILE PART OF
THE NORTHERN STATES TROUGH MAY EXTEND TO NEAR OUR AREA. THE MOISTER
AIRMASS REMAINS IN PLACE ESPECIALLY OVER OUR EASTERN AREAS WHERE THE
SLIGHT CHANCES FOR AFTERNOON SHOWERS AND THUNDERSTORMS CONTINUE EACH
DAY. HOWEVER, A POTENTIAL FOR SHOWERS AND THUNDERSTORMS MAY DEVELOP
FARTHER WEST FROM THE I-35 CORRIDOR TO THE RIO GRANDE PLAINS AS THE
MOISTER AIRMASS MAY SPREAD OVER THOSE AREAS. THOUGH TEMPERATURES
"COOL" A LITTLE, THE INCREASED MOISTURE KEEPS THE HEAT INDICES ABOUT
THE SAME.
