KEY MESSAGES
UPDATED AT 124 AM CDT WED AUG 5 2026
- CONTINUED HOT AND DRY FOR MOST OF SOUTH-CENTRAL TEXAS FOR THE NEXT
SEVEN DAYS.

CRITERIA BRIEFLY THIS AFTERNOON.
- THERE WILL BE A SLIGHT CHANCE FOR SHOWERS OR THUNDERSTORMS OVER

SHORT TERM
(TODAY THROUGH THURSDAY)
ISSUED AT 124 AM CDT WED AUG 5 2026
THE SUBTROPICAL RIDGE IS CENTERED OVER AZ/NM THIS EVENING WITH WEAK
ANTICYCLONIC FLOW OVER TEXAS. HIGH PRESSURE OVER THE GULF IS
PRODUCING SOUTHEASTERLY FLOW IN THE LOW LEVELS. THE AIRMASS OVER
SOUTH-CENTRAL TEXAS REMAINS HOT AND MOIST, ALTHOUGH IT IS A LITTLE
BIT COOLER AND A LITTLE BIT MOISTER THAN 24 HOURS AGO. IN THE SHORT
TERM THE THE CENTER OF THE UPPER RIDGE WILL DRIFT TO THE NORTH.
TODAY THAT WILL HAVE LITTLE AFFECT ON OUR WEATHER. EXPECT ANOTHER
HOT AND DRY DAY WITH HIGH TEMPERATURES ABOUT THE SAME AS TUESDAY.
THE COMBINATION OF HEAT AND HUMIDITY MAY BRING A FEW SPOTS OVER THE
COASTAL PLAINS TO HEAT ADVISORY LEVELS FOR A COUPLE OF HOURS, BUT WE
DON'T EXPECT ENOUGH COVERAGE TO ISSUE AN ADVISORY. WE HAVE KEPT RAIN
OUT OF THE FORECAST THIS AFTERNOON, BUT THERE IS A NON-ZERO CHANCE
FOR A SHOWER OR THUNDERSTORM OVER THE COASTAL PLAINS. AS THE UPPER
HIGH MOVES A LITTLE FARTHER AWAY TO THE NORTH TONIGHT AND THURSDAY
THERE WILL BE SOME MINOR HEIGHT FALLS OVER TEXAS. THIS WILL RESULT
IN SOME SLIGHTLY HIGHER POPS OVER THE COASTAL PLAINS THURSDAY
AFTERNOON. STILL MOST PLACES WILL BE DRY. HIGH TEMPERATURES WILL BE
ABOUT THE SAME AS TODAY. SOME INCREASE IN HUMIDITY MAY ALLOW FOR
WIDER COVERAGE OF HIGH HEAT INDICES AND POSSIBLY THE NEED FOR A HEAT
ADVISORY OVER THE COASTAL PLAINS.
LONG TERM
(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 124 AM CDT WED AUG 5 2026
THE UPPER RIDGE WILL REMAIN NEAR THE FOUR CORNERS REGION THROUGH THE
LONG TERM PERIOD. THIS WILL LEAD TO A FAIRLY STAGNANT FORECAST. HIGH
TEMPERATURES WILL STAY HOT AND NEAR NORMAL EACH DAY FRIDAY THROUGH
MONDAY. HUMIDITY WILL REMAIN LOW ENOUGH TO KEEP HEAT INDICES BELOW
HEAT ADVISORY CRITERIA, HOWEVER A FEW SPOTS IN THE COASTAL PLAINS
COULD BRIEFLY REACH CRITERIA EACH AFTERNOON. WITH UPPER RIDGE
FARTHER NORTH A FEW SHOWERS OR THUNDERSTORMS COULD MOVE OVER THE
COASTAL PLAINS EACH AFTERNOON. IF ANY PLACE GETS ANY RAIN, IT WILL
BE LUCKY.
AVIATION
(06Z TAFS)
ISSUED AT 1212 AM CDT WED AUG 5 2026
HAVE KEPT THINGS MOSTLY THE SAME AS THE PREVIOUS FORECAST. THE
PRIMARY CHANGE WAS TO INTRODUCE A TEMPO AT AUS FOR MVFR CEILINGS
BETWEEN 12-15Z AS HREF GUIDANCE INDICATES A 40-60% CHANCE FOR MVFR
DURING THIS TIMEFRAME, WHEREAS AT SAT AND SSF, IT IS GREATER THAN
A 90% CHANCE FOR MVFR CEILINGS. OTHERWISE, THE REST OF THE
FORECAST IS UNCHANGED OTHER THAN SOME MINOR TWEAKS TO WIND SPEEDS
AND GUSTS.
