DISCUSSION
ISSUED AT 1201 AM CST WED NOV 19 2025
AREAS OF FOG COULD MAKE FOR A SLOWER THAN NORMAL MORNING COMMUTE.
IT SHOULD GRADUALLY BURN OFF TOWARD MID MORNING. WITH SOME HIGHER
PW'S TRANSITIONING INLAND TODAY, SOME OF US MAY SEE SOME ISOLATED
TO MAYBE SCATTERED SHOWERS AROUND - ALBEIT MOSTLY INSIGNIFICANT IN
REGARDS TO AMOUNTS AND OVERALL DURATION. OTHERWISE, A WARM START TO
THE DAY WILL LEAD TO SOME MORE RECORD HIGHS BEING THREATENED THIS
AFTERNOON (CLL-86, IAH-85, HOU-84, GLS-81, PSX-82). SOMEWHAT SIMILAR
SET UP FOR TONIGHT INTO THURS, THOUGH FOG COVERAGE ISN'T ANTICIPATED
TO BE QUITE AS WIDESPREAD OR VSBY AS LOW.
UPPER LOW SEEN ON WATER VAPOR IMAGERY NEAR SOCAL WILL WEAKEN AND
KICK OUT INTO THE PLAINS THURS NIGHT & FRI. WOULD ANTICIPATE SOME
INCREASING SHRA/TSTM COVERAGE THURSDAY AFTERNOON FROM THE BIG BEND
AREA INTO OKLAHOMA AS DAYTIME HEATING, SURFACE TROF/FRONT, AND
LARGER SCALE LIFT WORK THEIR MAGIC. THEY'LL PROBABLY BEGIN
APPROACHING THE I-35 CORRIDOR LATE IN THE DAY AND EVENTUALLY INTO
OUR NECK OF THE WOODS THURSDAY NIGHT. BEST OVERALL DYNAMICS SHOULD
BE SITUATED TO OUR NORTH...AND WITH THE PRECIP MOVING INTO A
SOMEWHAT MORE STABLE ENVIRONMENT AS WE LOSE HEATING, I'D
EXPECT OVERALL INTENSITY TO BE WANING WITH TIME. WE WILL STILL NEED
TO KEEP AN EYE OUT ON THINGS SHOULD THINGS DECIDE TO ACCELERATE, BUT
OVERALL SEVERE RISK LOOKS FAIRLY LOW TO ME GIVEN THE CURRENT MODEL
CONSENSUS. THIS SYSTEMS ASSOCIATED FRONTAL BOUNDARY WILL SAG CLOSER
TO THE COAST ON FRIDAY AND COULD SERVE AS A WEAK FOCUS FOR SOME
ADDITIONAL SHRA/TSTM ACTIVITY IN ADVANCE DURING THE DAY. THE FRONT
WILL BE LOSING ITS SOUTHWARD MOMENTUM WITH TIME AND IT REMAINS TO BE
SEEN IF IT CLEARS THE COAST OR NOT BEFORE EVENTUALLY STALLING &
WASHING OUT.
ANOTHER WESTERN MID-UPPER TROF WILL SINK SOUTHWARD INTO BAJA
SATURDAY THEN BEGIN ITS EASTWARD JOURNEY TOWARD AND INTO TEXAS ON
MONDAY. THIS SYSTEM LOOKS TO BE DEEPER, AND SHOULD PROVIDE BETTER
CHANCES OF STORMS TO THE REGION MON AFTERNOON-TUE MORNING. 47

ISSUED AT 545 PM CST TUE NOV 18 2025
VFR CONDITIONS AND LIGHT SOUTHERLY TO SOUTHEASTERLY WINDS WILL
PREVAIL OVER THE NEXT FEW HOURS, THEN WINDS WILL BECOME LIGHT AND
VARIABLE AREAWIDE AFTER ~03Z. CEILINGS AND VISIBILITIES ARE
EXPECTED TO RAPIDLY DECREASE ACROSS THE REGION AFTER 06Z LEADING
TO WIDESPREAD IFR/LIFR CONDITIONS. THE WINDOW OF HIGHEST
CONFIDENCE FOR LIFR CONDITIONS IS ~09Z TO 13Z. LOW LEVEL CLOUD
CEILINGS WILL LIKELY STICK AROUND THROUGH 17/18Z BEFORE IMPROVING
TO VFR, SO EXPECT A GRADUAL CLIMB FROM IFR TO MVFR TO VFR BY THE
EARLY AFTERNOON HOURS. SOUTHEASTERLY WINDS AROUND 7-10 KT WILL
PREVAIL THROUGHOUT THE DAY ON WEDNESDAY. FOR WESTERN TERMINALS,
SOME ISOLATED TO SCATTERED RAIN SHOWERS ARE EXPECTED TO DEVELOP IN
THE EARLY TO MID AFTERNOON HOURS. THIS HAS BEEN HINTED AT FOR
CLL/SGR/LBX WITH A PROB30. ANOTHER ROUND OF WIDESPREAD REDUCED
VISIBILITIES AND CEILINGS IS EXPECTED WEDNESDAY NIGHT INTO
THURSDAY MORNING.

ISSUED AT 1201 AM CST WED NOV 19 2025
AREAS OF INLAND FOG MAY BLEED INTO PORTIONS OF GALVESTON BAY AND
THE NORTHERN HOUSTON SHIP CHANNEL OVERNIGHT CAUSING REDUCED
VISIBILITY. FOG SHOULD BURN OFF TOWARD MID MORNING. AREAS OF FOG
LOOK TO BE POSSIBLE AGAIN WEDNESDAY NIGHT, THOUGH NOT AS PREVALENT
AS TONIGHT. OTHERWISE, LIGHT TO MODERATE ONSHORE FLOW SHOULD
CONTINUE THROUGH THURSDAY NIGHT WITH GULF SEAS OF 2 TO 4 FEET. A
VERY WEAK FRONTAL BOUNDARY WILL SAG CLOSE TO THE COAST LATE FRIDAY
NIGHT OR SATURDAY MORNING THEN WASH OUT. ONSHORE WINDS QUICKLY
RESUME LATE IN THE DAY SATURDAY THEN INCREASE SUNDAY. 47
