KEY MESSAGES
ISSUED AT 1250 PM CDT TUE AUG 12 2025
- TYPICAL SUMMER-LIKE WEATHER IS EXPECTED THIS WEEK WITH ISOLATED TO
SCATTERED SHOWERS AND STORMS, WITH THE BEST CHANCES IN THE
AFTERNOON.
- HIGH TEMPERATURES MAINLY IN THE LOW TO MID 90S THROUGHOUT THE
WEEK WITH AN INCREASING TEMPERATURE TREND POSSIBLE OVER THE

DISCUSSION
ISSUED AT 1144 PM CDT TUE AUG 12 2025
THE PATTERN OF HEAT AND HUMIDITY WITH ISOLATED TO SCATTERED STORMS
CONTINUES WEDNESDAY THROUGH THE END OF THE WEEK AS WE REMAIN
STATIONED IN A WEAK UPPER LEVEL TROUGH. ELEVATED PWAT VALUES
(1.9-2.3" RANGE) ALONG WITH SURFACE CONVERGENCE AND SHORTWAVES
ALOFT WILL CONTRIBUTE TO SCATTERED SHOWERS AND THUNDERSTORMS
ACROSS THE AREA DURING THE AFOREMENTIONED PERIOD. EXPECT COVERAGE
TO START OUT OVER THE COASTAL WATERS DURING THE MORNING HOURS WITH
ACTIVITY SPREADING FURTHER INLAND DURING THE AFTERNOON HOURS.
RAIN CHANCES DECREASE LATER IN THE WEEKEND AND INTO NEXT WEEK AS
THE RIDGE BUILDS BACK IN FROM THE WEST. TEMPERATURES WILL BE ON
THE RISE AS A RESULT OF THIS. IN ADDITION TO THIS, ELEVATED
MOISTURE WILL CONTRIBUTE TO INCREASED HUMIDITY AND CONSEQUENTLY
HIGHER HEAT INDEX VALUES. HIGHS LATER IN THE WEEKEND AND INTO NEXT
WEEK WILL INCREASE INTO THE UPPER 90S WITH HEAT INDEX VALUES
TOPPING OUT IN THE 105-109F ACROSS MUCH OF THE AREA.
NHC HAS INTRODUCED A NEW AREA OF CONCERN IN THE SW GULF. AN AREA
OF DISORGANIZED SHOWERS AND STORMS IN THE NW CARIBBEAN WILL
GRADUALLY MOVE NW OVER THE NEXT SEVERAL DAYS. THERE IS A LOW (20%)
CHANCE OF TROPICAL DEVELOPMENT IN THE NEXT 7 DAYS AS IT MOVES INTO
THE SW GULF. AT THIS TIME IT IS TOO EARLY TO DETERMINE WHAT, IF
ANY IMPACTS WE WILL EXPERIENCE IN SE TEXAS. AS WE APPROACH THE
PEAK OF HURRICANE SEASON IT IS IMPORTANT TO REMAIN VIGILANT AND
PREPARED AND STAY UP TO DATE ON THE LATEST FORECASTS.
AVIATION
(12Z TAF ISSUANCE)
ISSUED AT 605 AM CDT WED AUG 13 2025
GENERALLY, LIGHT WINDS (VARIABLE IN THE MORNING, PREDOMINATELY
SOUTHEASTERLY IN THE AFTERNOON) AND VFR CONDITIONS WILL PREVAIL
THROUGH THE PERIOD. LIKE WE'VE SEEN THE PAST FEW DAYS, WE WILL SEE
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS OVER THE COAST IN THE
MORNING, THEN POP-UP THUNDERSTORMS INLAND IN THE AFTERNOON AND
EARLY EVENING. GUSTY WINDS AND HEAVY RAINFALL WILL BE POSSIBLE
NEAR ANY THUNDERSTORMS THE DEVELOP. A LULL IN THE ACTIVITY IS
EXPECTED LATE THIS EVENING THROUGH NEAR DAWN TOMORROW, THEN WE
START THE PROCESS AGAIN.

MARINE
ISSUED AT 1144 PM CDT TUE AUG 12 2025
OFFSHORE WINDS EARLY IN THE MORNINGS, AND ONSHORE WINDS IN THE
AFTERNOON AND EVENINGS CAN BE EXPECTED FOR THE NEXT SEVERAL DAYS
DUE TO SEA AND LAND BREEZES. LOW SEAS WILL ALSO PREVAIL THROUGH
MOST OF THE PERIOD. WITH ENOUGH MOISTURE AND THE PRESENCE OF A
WEAK SURFACE TROUGH ALONG THE COAST, ISOLATED TO SCATTERED SHOWERS
AND STORMS ARE EXPECTED EACH DAY, WITH THE BEST CHANCES/COVERAGE
THURSDAY AND FRIDAY.
