MID-UPPER TROF WILL CONTINUE MAKING ITS WAY INTO THE PLAINS TODAY.
IN THE LLVLS, 25-35KT H85 WINDS WILL DRAW 1.5-1.8" PW'S AHEAD OF AN
N-S ORIENTED FRONTAL BOUNDARY THAT WILL BE MAKING ITS WAY TOWARD
WESTERN PARTS OF THE REGION LATER IN THE DAY. LOOK FOR SOME
SHRA/TSTM DEVELOPMENT ACROSS THIS BOUNDARY THIS AFTERNOON, AS IT
PROGRESSES TOWARD THE BRAZOS VALLEY AFTER ABOUT 2PM OR SO. MAIN
CONCERN, HOWEVER, WILL BE ANY DISCREET CELLS THAN INITIATE IN
ADVANCE. THERE WILL BE SUFFICIENT INSTABILITY AND SHEAR WHEREAS SOME
OF THESE ISOLATED CELLS MIGHT BE CAPABLE OF BECOMING SEVERE WITH ALL
MODES OF SEVERE WX A POSSIBILITY. LOCATIONS NORTH OF ABOUT COLUMBUS-
CLEVELAND MIGHT BE THE PLACE TO WATCH BETWEEN 2-10PM. ELSEWHERE,
THERE'S PROBABLY A LOWER, BUT NON-ZERO THREAT OF SOME STRONGER CELLS
MONDAY EVENING/NIGHT AS STORMS MAINLY CONSOLIDATE ALONG THE SURFACE
BOUNDARY AND THE THREAT OF THE DISCREET ACTIVITY LOWERS. THIS
BOUNDARY WILL BECOME ORIENTED MORE W-E WITH TIME, AND LLVL JET
WEAKENS AND BECOMES SW MONDAY NIGHT. THIS SHOULD LEAD TO DIMINISHING
INTENSITY AS REMNANTS TRACKS CLOSER TO THE COAST OVERNIGHT. SO
OVERALL, KEEP AN EYE ON THE STAND-ALONE CELLS THIS AFTERNOON &
EVENING WHERE SEVERE STORMS ARE MORE PROBABLE. ELSEWHERE ALONG THE
BROKEN BAND, I'D LOOK FOR THE MAIN ISSUES TO BE SOME 25-50MPH GUSTS
AND MAYBE SOME HAIL.
HIRES DATA SHOWS THIS FRONT SAGGING OFF THE COAST EARLY TUESDAY
MORNING ENDING THE POPS INLAND...THOUGH SOME OF THE GLOBALS SHOW IT
TEMPORARILY STALLING OUT DURING THE DAY WITH SOME LINGERING SCT SHRA
CHANCES IN THE COASTAL COUNTIES DURING THE DAY (KIND OF SIMILAR TO
THE LAST FRONT). DON'T HAVE STRONG CONFIDENCE EITHER WAY, THOUGH I'D
PROBABLY LEAN CLOSER TO THE HIRES GUIDANCE ATTM.
STRONGER PUSH OF COOL, DRY AIR ARRIVES LATE TUE NIGHT AND WED
MORNING WHICH SHOULD BRING SOME NICE SEASONABLE WX THROUGH TURKEY
DAY.
ONSHORE WINDS RESUME FRIDAY...DRAWING DEEPER GULF MOISTURE INTO THE
REGION (AND WARMER TEMPS) THIS WEEKEND. GLOBAL MODELS AND BLENDS ARE
ALL MOSTLY BULLISH SHOWING A FAIRLY WET WEEKEND...BUT WITH A MAINLY
ZONAL FLOW AND LACK OF A SURFACE BOUNDARY/FORCING MECHANISM IN THE
VICINITY, I HAVE A BIT OF SKEPTICISM AT THIS POINT FOR TOTAL
WASHOUTS. 47
AVIATION
(12Z TAF ISSUANCE)
ISSUED AT 546 AM CST MON NOV 24 2025
A MIX OF MVFR-VFR WITH ESE-SE WINDS AT 5-10KT CURRENTLY OVER SE
TEXAS TAF SITES. WINDS WILL INCREASE TO 10-15KTS TODAY AND GUSTS
COULD RANGE BETWEEN 20-25KTS. SOME LIGHT STREAMER SHOWERS HAVE
BEEN PASSING THROUGH THE AREA EARLY THIS MORNING AND ARE EXPECTED
TO CONTINUE THROUGH LATE MORNING. THEN, SHOWERS AND STORMS WILL
DEVELOP IN THE AFTERNOON AND TONIGHT AHEAD OF AND ALONG THE NEXT
COLD FRONT. SOME STORMS WILL HAVE THE POTENTIAL TO BECOME STRONG
TO SEVERE AND MAY PRODUCE BRIEF HEAVY RAINFALL, HAIL, STRONG VRB
WINDS, FREQUENT LIGHTNING, LLVL WIND SHEAR, AND TURBULENCE.
ISOLATED TORNADOES CANNOT BE RULED OUT. MAIN REGION FOR THESE
STRONG STORMS WILL BE ALONG AND NORTH OF THE I-10 CORRIDOR,
ALTHOUGH A FEW STORMS COULD CONTINUE TO BE STRONG AS IT MOVES INTO
THE COASTLINE. EXPECT LIGHT W-NW WINDS OVERNIGHT INTO EARLY TUE
MORNING. CHANCE FOR SHOWERS AND STORMS WILL DECREASE TUE
AFTERNOON/EVENING AS THE FRONT PUSHES FURTHER INTO THE GULF
WATERS.
COTTO
MARINE
ISSUED AT 1203 AM CST MON NOV 24 2025
LOOK FOR INCREASING SOUTHEAST AND BUILDING SEAS OVERNIGHT AND INTO
MONDAY. MAY NEED SOME CAUTION FLAGS WEST OF FREEPORT IN THE MORNING.
THE NEXT WEATHER SYSTEM WILL MOVE INTO SOUTHEAST TEXAS LATER TODAY,
WITH THE TAIL END OF SOME SHOWERS AND ISOLATED STORMS TOWARD THE
COAST MONDAY NIGHT. CAN NOT RULE OUT AN ISOLATED STRONG STORM IN THE
GALVESTON BAY AREA BETWEEN ABOUT 10PM AND 5AM. RAIN CHANCES START TO
TAPER OFF TUESDAY DEPENDING ON WHEN A WEAK COLD FRONT MOVES OFF THE
COAST. A SECONDARY, STRONGER PUSH OF COOL DRY AIR WILL MOVE INTO THE
WATERS LATE TUESDAY NIGHT AND EARLY WEDNESDAY MORNING. NORTH WINDS
SHOULD INCREASE TO 20 TO 25 KNOTS AS THIS OCCURS ALONG WITH BUILDING
SEAS OFFSHORE. SMALL CRAFT ADVISORIES WILL BE REQUIRED. ONSHORE
WINDS RESUME AND INCREASE LATER IN THE WEEK. 47
