DISCUSSION
ISSUED AT 1139 AM CDT SUN AUG 31 2025
CONTINUING TO DEAL WITH A POCKET OF HIGHER ATMOSPHERIC MOISTURE IN
THE FORM OF HIGHER PWATS FROM FAR N TX INTO OUR PORTION OF DEEP
EAST TEXAS EXTENDING SOUTHWARD INTO SE TX AND ITS THIS REGION
WHERE WE CONTINUE SEEING SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS. AS WAS THE CASE ON SATURDAY, THIS WILL LIKELY BEGIN
DISSIPATING IN COVERAGE AND INTENSITY MUCH LATER THIS AFTERNOON
INTO THE EVENING HOURS, WITH THIS AXIS BEING A FAVORABLE LOCATION
FOR RENEWED DEVELOPMENT AFTER MIDNIGHT OR CLOSER TO SUNRISE BUT
NOT NEAR THE EXTENT OR COVERAGE WE'VE WITNESSED THE LAST 2
MORNINGS. NORTHWEST FLOW ALOFT IS PROVIDING THE NECESSARY UPPER
FORCING TO GENERATE THIS NOCTURNAL ACTIVITY WITH THE PRECIPITATION
SUSTAINING ITSELF DUE TO DIURNAL DAYTIME HEATING.
FOLLOWING THIS PWAT PATTERN THROUGH THE SHORT TERM HAS BEEN A
REALLY HANDY FORECAST TOOL LATELY AND HAVING SAID THAT, WE SHOULD
SEE A SPLIT IN THIS MOISTURE AXIS FOR LABOR DAY WITH MUCH HIGHER
MOISTURE ONCE AGAIN ACROSS OUR PORTION OF DEEP EAST TEXAS AND A
SECONDARY AREA OF A MORE SUBTLE PWAT MAXIMUM NEAR OR NORTH OF THE
I-30 CORRIDOR OR ACROSS THE MIDDLE RED RIVER VALLEY OF NE TX, SE
OK AND SW AR. FOR THIS REASON, I HAVE SPLIT HIGHER CHANCE POPS FOR
MONDAY ACROSS THESE TWO LOCATIONS WITH ONLY ISOLATED CONVECTIVE
COVERAGE POSSIBLE ALONG THE I-20 CORRIDOR OF NE TX INTO NW LA.
BEYOND LABOR DAY, A STRONG UPPER LEVEL TROUGH, EMBEDDED IN
NORTHWEST FLOW ALOFT, WILL RAPIDLY MOVE SOUTH AND EAST ACROSS THE
UPPER MIDWEST INTO THE TENN VALLEY LATE TUE INTO TUE NIGHT. A COLD
FRONT WILL BE ASSOCIATED WITH THIS UPPER LEVEL TROUGH AND THIS
DISTURBANCE SHOULD HAVE JUST ENOUGH MOISTURE AVAILABLE SUCH THAT
ISOLATED TO SCATTERED CONVECTION WILL BE POSSIBLE WITH THE HIGHER
POPS WARRANTED WHERE THE HIGHER MOISTURE CONTENT AND UPPER
FORCING WILL BE LOCATED ACROSS OUR NORTHERN AND EASTERN MOST
ZONES. THAT FRONT WON'T HAVE MUCH IN THE WAY OF COOLER AIR SO TO
SPEAK BUT IT WILL HELP TO DRY OUR ATMOSPHERE OUT BY THE TIME THE
NEXT COLD FRONT MAKES ITS WAY INTO OUR REGION DURING THE DAY
THURSDAY.
IT'S THE THURSDAY COLD FRONT THAT WILL HAVE A GLANCING BLOW OF
SOME MILDER AIR ASSOCIATED WITH THIS POST-FRONTAL AIRMASS AND THE
MOST NOTICEABLE DIFFERENCE WILL BE FELT AT NIGHT AND MORE SO
ACROSS OUR NORTHERN AND FAR NORTHEASTERN ZONES WHERE IT WILL BE
POSSIBLE FOR TEMPERATURES IN THE UPPER 50S FOR OVERNIGHT LOWS BOTH
THU NIGHT AND AGAIN FRI NIGHT.
IT APPEARS THIS NORTHWEST FLOW ALOFT UPPER LEVEL PATTERN WILL
FLATTEN OUT BY NEXT WEEKEND WITH MAYBE A LITTLE MORE FORCING
MOVING ACROSS TEXAS TO ENCOURAGE AT LEAST SLIGHT CHANCE TO LOW END
CHANCE POPS ACROSS OUR WESTERN HALF WITH RETURNING NEAR NORMAL
EARLY SEPTEMBER TEMPERATURES FOR LATE THIS WEEK INTO NEXT WEEKEND.

AVIATION
(00Z TAFS)
ISSUED AT 635 PM CDT SUN AUG 31 2025
FOR THE 01/00Z TAFS, REMAINING LOWER VFR CLOUDS WILL MAKE WAY FOR
HIGH CLOUDS TO PREVAIL THROUGH MUCH OF THE NIGHT. ANOTHER AREA OF
SHOWERS AND STORMS IS MOVING EAST ACROSS NORTH TEXAS, AND MAY
IMPACT KTXK LATE OVERNIGHT TONIGHT. TERMINALS WHICH SAW
PRECIPITATION TODAY MAY SEE PATCHY FOG DEVELOPMENT TOWARDS DAWN.
CARRYING IMPACTS FOR KTYR AND KLFK. FURTHER RAIN IMPACTS ARE
POSSIBLE INTO TOMORROW, BUT CURRENT CONFIDENCE DOES NOT YET MERIT
INCLUDING PREVAILING CONDITIONS. EAST WINDS WILL BECOME LIGHT
OVERNIGHT, BECOMING MORE SOUTHEASTERLY TOMORROW AT SPEEDS OF NOT
MUCH MORE THAN 5 KTS, BECOMING MORE VARIABLE IN DIRECTION TOWARDS
THE END OF THIS FORECAST PERIOD.
