MID-UPPER LEVEL RIDGING EXTENDING FROM THE CAROLINAS ACROSS THE DEEP
SOUTH AND INTO EAST TEXAS WILL PROVIDE ONE MORE HOT DAY ACROSS THE
REGION ON THURS WITH HIGHS AGAIN FLIRTING WITH THE TRIPLE DIGITS.
WE'VE BEEN MANAGING TO MIX OUT JUST ENOUGH DRIER AIR IN THE
AFTERNOONS TO KEEP HEAT INDICES MOSTLY BELOW THE 108F HEAT ADVSY
CRITERIA, AND THE HOPE IS WE CAN DO IT ONE MORE TIME. REGARDLESS,
IT'S PLENTY UNCOMFORTABLE OUT THERE AND ENCOURAGE THOSE OUTDOORS TO
TAKE THE USUAL HEAT PRECAUTIONS. UNLESS WE SEE SOME TRENDS THAT
POINT OTHERWISE LATER THIS AFTERNOON, THE PLAN IS TO FORGO A HEAT
ADVSY FOR THURS AND LET THE NIGHT CREW TAKE ANOTHER GLANCE AT
THINGS.
INVERTED TROF IS SITUATED SOUTH OF THE RIDGE MENTIONED
ABOVE...ROUGHLY FROM THE NORTHERN CARIBBEAN ACROSS CUBA-FL-AND INTO
THE ATLANTIC. THIS FEATURE WILL TRACK WESTWARD TOWARD THE TX AND
WESTERN GULF COAST FRI-SAT. CURRENTLY, THERE'S SOME ASSOCIATED
UNSETTLED WX, ALBEIT QUITE UNORGANIZED, TO THE EAST AND WEST OF
THE AXIS. NHC CONTINUES TO KEEP AN EYE ON THINGS AS SOME GUIDANCE
INDICATES THE POTENTIAL FOR A WEAK SURFACE REFLECTION/LOW TO
DEVELOP (AND THAT'S JUST A SUBSET OF ALL THE AVAILABLE ENSEMBLES).
SO MORE OR LESS, WE'RE CURRENTLY LOOKING AT AN AXIS OF DEEPER
GULF MOISTURE TO BEGIN MAKING ITS WAY INTO THE REGION FROM THE
EAST LATE THURS (EVENING- ISH) BRINGING SOME ISO-SCT PRECIP AROUND
THE GALVESTON BAY AREA. EVENTUALLY HIGHER PW AIR MAKES IT INTO
MOST OF THE AREA FRIDAY AND SATURDAY WHEN WE SHOULD SEE MORE
CLOUDINESS, LOWER DAYTIME HIGHS, AND BETTER RAIN CHANCES ACROSS SE
TX.
RIDGING SHOULD GRADUALLY BUILD BACK INTO THE REGION FROM THE
EAST/NORTHEAST LATER IN THE WEEKEND AND INTO NEXT WEEK.
CORRESPONDING RAIN CHANCES TREND DOWN AND TEMPS BACK UP. 47

(00Z TAF ISSUANCE)
ISSUED AT 619 PM CDT WED JUL 23 2025
WINDS CONTINUING THEIR SEASONAL CYCLE AGAIN, BUT PERHAPS WITH A
BIT MORE OF A PRONOUNCED SWING, WITH A DECIDED SW'LY DIRECTION
LATE TONIGHT, BECOMING SE OR EVEN ESE TOMORROW AFTERNOON. PRE-DAWN
STRATUS AND/OR FOG SHOULD MAINLY BE AN ISSUE AWAY FROM THE TAF
SITES, BUT DO HAVE A BRIEF MVFR CIG AT CLL, AND VSBY FOR SGR/LBX.
AT THE I-45 TERMINALS, I HOLD IN VFR, BUT WITH LIBERAL MENTIONS OF
FEW/SCT CLOUDS AT MVFR LEVELS THAT CAN BE STEPPED UP IF A BROADER
STRATUS DECK MATERIALIZES.

ISSUED AT 127 PM CDT WED JUL 23 2025

A WEAK TROUGH WILL PUSH TOWARD THE WESTERN GULF AND TEXAS COAST

WEATHER. 47
