DISCUSSION

ELONGATED, FLAT MID LEVEL RIDGE CURRENTLY STRETCHES FROM THE DESERT
SOUTHWEST EASTWARD ACROSS THE CAROLINAS. AN INVERTED TROF ACROSS THE
WESTERN GULF, ALONG WITH SOME TROFFINESS MOVING ACROSS THE NCNTL
U.S. SHOULD CARVE OUT A GENERAL WEAKNESS AND SPLIT THE RIDGE (TO OUR
EAST/WEST). THIS WEAKNESS SHOULD MOSTLY PERSIST INTO THE WEEKEND,
AND WITH A TOUCH LESS SUBSIDENCE TO OVERCOME, ALLOW FOR CHANCES OF
SCATTERED SHOWERS/THUNDERSTORMS ON A DAILY BASIS. WITH LACK OF
SIGNIFICANT FORCING OTHER THAN THE SEABREEZE/BAYBREEZE, THESE WILL
MOSTLY BE DIURNALLY DRIVEN WITH HIGHEST COVERAGE LATE AT NIGHT AND
MORNINGS OFFSHORE TRANSITIONING INLAND DURING THE DAY AFTER SOME
HEATING. PW'S OF 2.0-2.2" ACROSS THE SOUTHERN HALF OF THE AREA WOULD
SUGGEST THE PROBABILITIES OF THE HIGHER COVERAGE BEING SITUATED
THERE MORESO THAN IN THE BRAZOS VALLEY & PINEY WOODS.
THE EASTERN PORTION OF THE RIDGE LOOKS TO REGAIN ITS STRENGTH AND
GRADUALLY EXPAND BACK INTO THE REGION EARLY-MID NEXT WEEK...NOT
ELIMINATING RAIN CHANCES - BUT ALLOWING SUBSIDENCE TO PUT UP MORE
OF A FIGHT. 47
AVIATION
(06Z TAF ISSUANCE)
ISSUED AT 1217 AM CDT WED SEP 9 2026
WINDS CONTINUE TO RELAX AS THE OVERNIGHT HRS PERSIST. AS THE
MORNING ARRIVES, INCREASED COASTAL MOISTURE COUPLED WITH THE SEA
BREEZE BRINGS SHOWERS AROUND GLS/LBX. AS DAYTIME HEATING ENSUES,
PAIRED WITH THE SEA BREEZE PUSHING INLAND, THESE SHOWERS ARE
ANTICIPATED TO EVOLVE INTO ISOL-SCT CONVECTION. TIMING AND
PLACEMENT HAVE BECOME MORE CONCISE THUS TEMPO GROUPS BEING ADDED
FOR THE 1-10 CORRIDOR AND SOUTH. THE DEPTH OF THE SEA BREEZE STILL
REMAINS VARIED, THUS CONTINUED MONITORING WILL OCCUR TOMORROW FOR
WHEN/IF TEMPO GROUPS ARE ADDED. ALL ACTIVITY IS ANTICIPATED TO
DIMINISH AROUND SUNDOWN KEEPING PREVAILING VFR CONDITIONS WITH A
ESE BREEZE.
MARINE
ISSUED AT 1217 AM CDT WED SEP 9 2026
LIGHT ONSHORE FLOW AND LOW SEAS WILL PREVAIL FOR THE NEXT SEVERAL
DAYS, PERHAPS INCREASING A TOUCH BY THE END OF THE WORK WEEK AS THE
PRESSURE GRADIENT SLIGHTLY TIGHTENS. THE MAIN CONCERN FOR MARINERS
WILL BE DODGING THE LATE NIGHT AND MORNING SCATTERED SHOWERS AND
THUNDERSTORMS. WE HAD SOME REPORTS OF FUNNELS/WATERSPOUTS THE
PAST DAY OR TWO. ENVIRONMENT TODAY IS SIMILAR, WITH A LIGHT FLOW
REGIME IN PLACE SO WE WOULN'T BE OVERLY SURPRISED TO SEE A FEW
MORE REPORTS OF THESE. (NOT ABNORMAL IN THESE ENVIRONMENTS,
TYPICALLY SHORT-LIVED, AND OCCUR IN THE EARLY AND MID MORNING
HOURS). 47
