DISCUSSION
ISSUED AT 100 PM CDT TUE AUG 11 2026
REMNANT WEAK VORT LOBE NEAR THE BRAZOS VALLEY, DAYTIME HEATING,
SEABREEZE, AND 2" PW'S ARE ALLOWING FOR SOME SCATTERED SHOWER AND
THUNDERSTORM ACTIVITY TO GET GOING THIS AFTERNOON. THIS PRECIP
WILL TAPER OFF TOWARD EARLY EVENING WITH THE LOSS OF HEATING.
RIDGING, BOTH IN THE LOWER AND UPPER LEVELS SITUATED ACROSS THE NE
PARTS OF THE GULF WILL VERY SLOWLY TRACK AND EXPAND WESTWARD FOR
THE REMAINDER OF THE WEEK AND WEEKEND. WITH BUILDING HEIGHTS COME
SLIGHTLY WARMER CONDITIONS...BUT JUST BACK INTO THE "SEASONABLY
AUGUST HOT" TERRITORY. GOOD NEWS IS WE SHOULD SEE SOME INCREASED
WIND SPEEDS TO PARTIALLY MITIGATE THOSE READINGS IN THE MID AND
UPPER 90S WED-FRI.
IN TERMS OF RAIN CHANCES, SLIGHTLY LOWER PW AIR IS FORECAST TO
MOVE INTO THE AREA WEDNESDAY SO WE SHOULD SEE LOWER (BUT NOT NIL)
SHRA/TSTM CHANCES AND LESS AREAL COVERAGE COMPARED TO WHAT WE SAW
MONDAY AND TODAY. ATMOSPHERE APPEARS EVEN DRIER THURSDAY. WE'LL
REMAIN WITHIN A CORRIDOR OF SOUTHERLY WINDS OFF THE GULF, AND
MINOR FLUCTUATIONS OF MOISTURE AVAILABILITY WILL DRIVE ANY DIURNALLY
DRIVEN SEABREEZE POPS INTO THE WEEKEND. THAT SAID, WE'RE STILL
ONLY TALKING <30% CHANCES...SO MOST OF US WILL PROBABLY REMAIN
DRY. 47

(00Z TAF ISSUANCE)
ISSUED AT 607 PM CDT TUE AUG 11 2026
LINGERING ISOLATED SHRA/TSRA WILL QUICKLY DISSIPATE THIS EVENING
AS WE LOSE DAYTIME HEATING. WINDS OVERNIGHT BECOME LIGHT, WITH
SOME MVFR CIGS DEVELOPING IN OUR NORTHERN ZONES BY EARLY MORNING.
SOUTHERLY WINDS ARE EXPECTED TO BE GUSTIER ON THURSDAY, POSSIBLY
GUSTING OVER 20 KNOTS. WINDS MAY BECOME MORE SOUTHEASTERLY IN
BY LATE THURSDAY AFTERNOON.
MARINE
ISSUED AT 100 PM CDT TUE AUG 11 2026
A PREVAILING SOUTHERLY FLOW WILL CONTINUE FOR THE NEXT SEVERAL
DAYS. WIND SPEEDS SHOULD INCREASE WEDNESDAY NIGHT INTO FRIDAY AS
THE PRESSURE GRADIENT TIGHTENS AND ALLOW FOR SEAS TO BUILD INTO
THE 3 TO 5 FOOT RANGE. CAUTION FLAGS MAY BE NEEDED AT TIMES. AS
HIGHER PRESSURE BUILDS INTO THE REGION FROM THE EAST, WINDS AND
SEAS SHOULD DIMINISH THIS WEEKEND. 47
