SHORT TERM
(TONIGHT THROUGH TUESDAY NIGHT)
ISSUED AT 1247 PM CDT MON AUG 3 2026
IF YOU WERE AROUND THE HILL COUNTRY ESPECIALLY THE FREDERICKSBURG
AND KERRVILLE AREAS THIS MORNING, THEN YOU ENJOYED THE LOWEST LOW
TEMPERATURES IN WEEKS. LOWS GOT DOWN TO THE LOW 60S OVER THOSE
LOCATIONS. THE REST OF THE LOCAL AREA OBSERVED LOWS IN THE MID TO
UPPER 60S TO LOW 70S, WHICH WAS ALSO NICE FOR THIS TIME OF THE YEAR.
UNDER SUNNY/PARTLY CLOUDY SKIES EARLY THIS AFTERNOON WITH TREND
STAYING THROUGH THE PERIOD, TEMPERATURES CONTINUE TO GO UP WITH
FORECAST HIGHS RANGING FROM THE MID TO UPPER 90S ACROSS PARTS OF
THE HILL COUNTRY AND SOUTHERN EDWARDS PLATEAU TO 100-102
ELSEWHERE. HEAT INDEX VALUES ARE FORECAST TO STAY CLOSE OR
SLIGHTLY ABOVE THE AMBIENT TEMPERATURES. HOWEVER, THERE ARE
PORTIONS OF THE COASTAL PLAINS WHERE DEWPOINT TEMPERATURES ARE
LIKELY TO RANGE FROM THE LOW TO MID 70S RESULTING IN INDEX VALUES
BETWEEN 108 TO 110 FOR FEW HOURS. SINCE THIS LOOKS TO BE OVER
ISOLATED SPOTS, I AM ISSUING A SPECIAL WEATHER STATEMENT INSTEAD
OF HEAT ADVISORY FOR A WIDESPREAD AREA. OTHER THAT THE HEAT,
INCREASED MOISTURE BEGINS TO REACH THE LOCAL AREA OVERNIGHT INTO
TUESDAY MORNING WITH SOME LOW CLOUDS DEVELOPING THROUGH THE
PERIOD. CLOUDS BREAK MID TO LATE MORNING GIVING WAY TO MOSTLY
SUNNY TO SUNNY SKIES ON TUESDAY. FORECAST HIGHS ARE VERY SIMILAR
TO THOSE TODAY WITH SIMILAR HEAT INDEX VALUES. WE WILL MONITOR
CLOSELY THOSE AFTERNOON DEWPOINT VALUES IN CASE REACHING HEAT
ADVISORY CRITERIA OVER A WIDESPREAD AREA.
LONG TERM
(WEDNESDAY THROUGH NEXT MONDAY)
ISSUED AT 1247 PM CDT MON AUG 3 2026
CONTINUED HOT AND DRY FOR THE MOST PART THROUGH THE WORK WEEK INTO
THE WEEKEND. SOME MODELS INDICATE THE SEABREEZE PUSHING ACROSS THE
COASTAL PLAINS THURSDAY AND FRIDAY AFTERNOONS. THE COMBINATION OF
THE SEABREEZE AND INCREASED GULF MOISTURE COULD BE ENOUGH TO
GENERATE ISOLATED SHOWERS AND EVEN AN ISOLATED THUNDERSTORM OR TWO
OVER PORTIONS OF THE COASTAL PLAINS.
