ISSUED AT 520 PM CDT THU AUG 6 2026
AN OUTFLOW BOUNDARY IS MOVING TOWARD I-35 AND GENERATING ISOLATED
SHOWERS AND THUNDERSTORMS. WE'VE ADDED SOME ISOLATED CONVECTION
INTO THE CENTRAL I-35 CORRIDOR FOR THE NEXT FEW HOURS.
SHORT TERM
(TONIGHT THROUGH FRIDAY NIGHT)
ISSUED AT 1200 PM CDT THU AUG 6 2026
SCATTERED CUMULUS CLOUDS ARE MOVING FROM THE COASTAL PLAINS INTO
THE I-35 CORRIDOR AND HILL COUNTRY AS OF 12:30 PM CDT. OVER THE
DEL RIO AREA, A LOW OVERCAST DECK IS HANGING THERE, HOWEVER, THOSE
CLOUDS ARE FORECAST TO DISSIPATE IN THE NEXT FEW HOURS. FORECAST
HIGHS ARE ON TRACK WITH TEMPERATURES RANGING FROM THE LOW TO UPPER
90S AND UP TO 103 ACROSS THE SOUTHERN RIO GRANDE PLAINS. HEAT
INDEX VALUES ARE FORECAST TO REACH UP TO 107 ALONG THE I-35
CORRIDOR AND UP TO 108 OVER PARTS OF THE SOUTHERN RIO GRANDE
PLAINS. CAN'T RULE OUT A FEW SPOTS ACROSS THE FAR SOUTHEAST
COUNTIES OR EAST OF LA GRANGE TO GONZALES TO KENEDY LINE TO
BRIEFLY REACH HEAT ADVISORY CRITERIA. OTHERWISE, MOST AREAS OF
SOUTH-CENTRAL TEXAS ARE STAYING DRY FOR THE REST OF THIS AFTERNOON
AND EVENING. HOWEVER, ISOLATED SHOWERS OR THUNDERSTORMS ARE
POSSIBLE OVER PORTIONS OF THE COASTAL PLAINS FOR THE AFTERNOON
PERIOD. THE BEST PROBABILITIES STAY EAST OF THE I-35 CORRIDOR
ESPECIALLY EAST OF LA GRANGE TO GONZALES TO KENEDY LINE. THIS
ACTIVITY MAIN DRIVER IS THE SEABREEZE PUSHING NORTH TO NORTHWEST
FOR THE PERIOD. IF ANY OF THESE SHOWERS OR STORMS DEVELOP, THEY
ARE ENDING BY 7 PM OR SO AS THE SUN GOES DOWN.
CLOUDS BEGIN TO REDEVELOP LATE TONIGHT THROUGH FRIDAY MORNING WITH
A LIGHT SOUTHERLY WIND FLOW OVER MOST LOCATIONS. WINDS ARE
FORECAST TO HAVE AN EASTERLY DIRECTION ACROSS THE RIO GRANDE
PLAINS.
A SIMILAR WEATHER DAY LIKE TODAY IS FORECAST FOR FRIDAY ACROSS THE
LOCAL AREA WITH CLOUDS DISSIPATING LATE MORNING GIVING WAY TO
PARTLY CLOUDY TO MOSTLY SUNNY SKIES IN THE AFTERNOON. FORECAST
HIGHS IN THE LOW TO UPPER 90S AND UP TO 103 OVER PORTIONS OF THE
SOUTHERN RIO GRANDE PLAINS. HEAT INDEX VALUES IN THE 100 TO 107
RANGE OVER MOST PART WITH A FEW LOCATIONS HITTING HEAT ADVISORY
CRITERIA BRIEFLY.
LONG TERM
(SATURDAY THROUGH NEXT THURSDAY)
ISSUED AT 1200 PM CDT THU AUG 6 2026
THE WEATHER PATTERN DOES NOT CHANGE A WHOLE LOT FOR THE WEEKEND
INTO THE MIDDLE OF NEXT WEEK. CONTINUED HOT AND DRY WITH THE
EXCEPTION OF SEA BREEZE ACTIVITY EACH AFTERNOON OVER PORTIONS OF
THE COASTAL PLAINS. THE SUBTROPICAL RIDGE REMAINS IN CONTROL OF
THE LOCAL AREA FOR THE NEXT SEVERAL DAYS. BY THE WEEKEND, THE
UPPER LEVEL HIGH MOVES SLIGHTLY TO THE WEST AND ALLOWS AN INVERTED
UPPER LEVEL TROUGH TO PUSH ACROSS THE LOCAL AREA. THAT WEAKNESS
STAYS THROUGH TUESDAY AND THEN AN UPPER LEVEL RIDGE DEVELOPS OVER
GULF STATES TO KEEP SOUTH-CENTRAL TEXAS DRY AND HUMID. BEST
CHANCES FOR SHOWERS AND STORMS REMAIN ACROSS THE COASTAL PLAINS.
