SHORT TERM
(TONIGHT THROUGH TUESDAY NIGHT)
ISSUED AT 618 PM CDT SUN OCT 19 2025
CURRENT CONDITIONS ARE PLEASANT, WITH TEMPERATURES RANGING FROM
THE LOWER 70S TO THE LOWER 80S UNDER SUNNY SKIES. A SURFACE HIGH
PRESSURE SYSTEM IS MOVING TOWARD THE REGION FROM TEXAS, PUSHING
THE COLD FRONT CURRENTLY OVER THE GULF WATERS. NORTHERLY WINDS ARE
A BIT GUSTY THIS AFTERNOON AND WILL REMAIN BREEZY UNTIL THE HIGH
PRESSURE IS ATOP THE REGION LATER THIS EVENING AND INTO TONIGHT.
TONIGHT, LIGHT NORTHEASTERLY WINDS AND CLEAR SKIES WILL FAVOR
TEMPERATURES DROPPING INTO THE UPPER 40S TO MID 50S.
THE HIGH PRESSURE WILL BE SWIFTLY SHIFTING EASTWARD, LEADING TO
EASTERLY TO SOUTHEASTERLY WINDS RETURNING BY MONDAY MORNING, AND
THEN SOUTHERLY BY MIDDAY. AS A RESULT, GULF MOISTURE WILL RETURN
TO THE REGION AHEAD OF ANOTHER COLD FRONT THAT WILL SWEEP THROUGH
ON TUESDAY. THE COMBINATION OF THE FRONT AND THE RETURNING
MOISTURE WILL BRING ISOLATED SHOWERS BACK INTO THE FORECAST.
HOWEVER, THIS ACTIVITY WILL BE SHORT LIVED AS THE FRONT IS
EXPECTED TO MOVE THROUGH QUICKLY, WITH WINDS ONCE AGAIN RETURNING
FROM THE NORTH BY TUESDAY EVENING.
LONG TERM
(WEDNESDAY THROUGH NEXT SATURDAY)
ISSUED AT 618 PM CDT SUN OCT 19 2025
A SIMILAR PATTERN IS EXPECTED, WITH NORTHERLY FLOW NOT LASTING
LONG AS THE SURFACE HIGH MOVES OFF TO THE EAST. SOUTHERLY TO
SOUTHEASTERLY FLOW WILL ONCE AGAIN ADVECT GULF MOISTURE INTO THE
REGION. THIS RECOVERY COMES AHEAD OF YET ANOTHER COLD FRONT. THE
PRIMARY DIFFERENCE BETWEEN THIS AND THE SHORT TERM SETUP IS THE
HIGHER PWAT VALUES EXPECTED, THANKS TO THE SLIGHTLY LONGER
DURATION OF SOUTHERLY FLOW. ISOLATED TO SCATTERED SHOWERS WILL
MAKE THEIR WAY BACK INTO THE FORECAST FROM FRIDAY THROUGH
SATURDAY.
AVIATION
(00Z TAFS)
ISSUED AT 618 PM CDT SUN OCT 19 2025
NORTHEAST WINDS ARE BEGINNING TO DIMINISH AS HIGH PRESSURE BUILDS
IN ALOFT. WINDS WILL BECOME CALM AFTER SUNDOWN. RADIATIVE COOLING
MAY RESULT IN SOME PATCHY FOG BUT DUE TO DRY AIR IN THE REGION,
CONFIDENCE IS LOW FOR PLACEMENT AND VIS.
VFR CEILINGS WILL PREVAIL THRU THE PERIOD. WINDS SHIFT AROUND TO
THE SOUTHEAST AND THEN SOUTH ON MONDAY AS HIGH PRESSURE MOVES TO
THE EAST.
