DISCUSSION
ISSUED AT 230 PM CDT FRI SEP 12 2025
WITH DOMINANT HIGH PRESSURE AT THE SFC AND ALOFT, WE'VE STILL
MANAGED TO DERIVE A FEW VERY ISOLATED SHOWERS NEAR TOLEDO BEND
THIS AFTERNOON, LIKELY THE RESULT OF WEAK DIFFERENTIAL HEATING.
OTHERWISE, IT'S A CONTINUATION OF THIS STAGNANT LATE SUMMER HEAT
PATTERN COURTESY OF A STUBBORN UPPER-LEVEL RIDGE THAT REMAINS
ANCHORED ACROSS MUCH OF THE SOUTHERN AND CENTRAL U.S. THEREFORE,
PERSISTENCE IS THE NAME OF THE FORECAST GAME THROUGH THIS WEEKEND
WITH HIGH TEMPERATURES STILL CLIMBING INTO THE LOWER AND MIDDLE
90S WHILE LOWS WILL RANGE FROM THE UPPER 60S TO MID 70S WITH SOME
PATCHY FOG POSSIBLE ONCE AGAIN IN ISOLATED LOCATIONS.
AS THIS PERSISTENT PATTERN CARRIES INTO THE NEW WORK WEEK, SOIL
MOISTURE WILL BECOME FURTHER DEPLETED THROUGHOUT THIS PERIOD OF
EXTENDED HEAT AND DRYNESS. ALTHOUGH FIRE WEATHER CONDITIONS ARE
NOT PARTICULARLY CONCERNING RIGHT NOW, THIS COULD BECOME MORE
PROBLEMATIC IF A PATTERN CHANGE DOESN'T MATERIALIZE LATER ON THIS
MONTH. FORTUNATELY, THERE ARE SUBTLE SIGNS THAT RIDGE MAY BEGIN TO
SLIGHTLY WEAKEN AS WE PROGRESS FROM MID TO LATE NEXT WEEK. THIS
IS THE FIRST REAL INDICATION OF SOME POSSIBLE RELIEF IN THE OFFING
BY THE END OF NEXT WEEK WITH AN UPPER-LEVEL TROUGH AND ACCOMPANYING
COLD FRONT SPILLING SOUTH FROM THE PLAINS AND MIDWEST BY THURSDAY
INTO FRIDAY.

AVIATION
(18Z TAFS)
ISSUED AT 1236 PM CDT FRI SEP 12 2025
FOR THE 12/18Z TAFS...A SCATTERED CU FIELD IS DEVELOPING ACROSS
THE REGION AND WILL CONTINUE INTO THE AFTERNOON. SHORT-RANGE
GUIDANCE HAS CLOUD COVER DECREASING THROUGH THE DAY, WITH A FEW
HIGHER LEVEL CLOUDS BEING THE ONLY COVERAGE FOR MUCH OF THE
OVERNIGHT HOURS. THE SAME GUIDANCE HAS CLOUD COVER INCREASING
TOWARDS THE END OF THE PERIOD WITH SOME MOISTURE ADVECTION. BUT
I'VE KEPT THE FORECAST TO THE TYPICAL CU FIELD DEVELOPMENT FOR
NOW DUE TO UNCERTAINTY. WINDS WILL GENERALLY STAY LIGHT/VARIABLE
THROUGH THE PERIOD.
