KEY MESSAGES
ISSUED AT 1244 AM CDT FRI AUG 29 2025
- FLOOD WATCH IS NOW IN EFFECT UNTIL 1PM THIS AFTERNOON.
- THE BACKDOOR FRONT IS MOVING TOWARD I-10 NOW WITH NE WINDS, BUT
THE UPPER LEVEL WINDS FROM THE NW WILL LINGER FOR DAYS YET.
THIS WILL BE KEEPING SKIES MOSTLY GRAY FOR MUCH OF THE WEEKEND
WITH GENERALLY LIGHTER RAINFALL AMOUNTS THROUGH SUNDAY.
- LABOR DAY IS LOOKING MUCH DRIER WITH SUNSHINE RETURNING AND
JUST A SLIGHT CHANCE FOR SOME RAIN SOUTH OF I-20. THE BEST NEWS
IS THAT METEOROLOGICAL FALL IS A FEW DAYS EARLY.
DISCUSSION
ISSUED AT 1244 AM CDT FRI AUG 29 2025
THE NE WINDS HAVE RETURNED WITH OUR COOL FRONT/MCS OUTFLOW AND
ARE NOW BLOWING WELL SOUTH OF I-20 ALONG WITH COOLER READINGS IN
THE UPPER 60S AND LOWER 70S. SHOWERS AND THUNDERSTORMS CONTINUE
TO DEVELOP AND INTENSIFY MOVING ACROSS I-30 INTO SW AR AND N LA.
MEANWHILE, THE BIG LATE DAY INITIAL PUSH HAS MOVED THROUGH OUR
SOUTHERN TIER OF CO./PA. JUST OVER LAST FEW HOURS.
RAINFALL SO FAR HAS BEEN LIMITED BY THE PROGRESSIVE MOVEMENT, BUT
A FEW AREAS SAW SOME STORM TRAINING, BUT MUCH MORE OF THAT WILL
REMAIN POSSIBLE AS THE NW FLOW CONTINUES TO SEND WEAK DISTURBANCES
DOWN I-49 TONIGHT AND TO SOME EXTENT INTO THE WEEKEND. THE FLOOD
WATCH INDICATES WHERE MOST OF THESE HEAVIER ELEMENTS AND
POTENTIAL TRAINING WILL OCCUR THROUGH ABOUT LUNCH TIME. SKIES
WILL REMAIN CLOUDY AND RAIN REMAINS POSSIBLE FOR MOST OF THE
WEEKEND PROPER, BUT AMOUNTS WILL BE LIGHTER SATURDAY AND SUNDAY
OVERALL AS NE WINDS VEER TO E WITH A SURFACE LOW RIDING ALONG THE
FRONT TO OUR SOUTH.
THE WPC MAINTAINS MARGINAL RISK EROS FOR THE WEEKEND AS THE
GROUND CONTINUES TO WET. THE HEAVIER AMOUNTS WILL BE ENDING BY
THIS AFTERNOON, BUT THE UPPER LEVEL NW FLOW OVER THE COOLER AIR
MASS WILL KEEP SKIES GRAY AND RAIN POSSIBLE FOR THIS EXTENDED
PERIOD OF NEEDED RAINFALL. THE SPC CONTINUES A MARGINAL RISK FOR
MOSTLY TOLEDO BEND COUNTRY OF TX AND LA FOR THE DAY ONE OUTLOOK.
LABOR DAY IS LOOKING QUITE GRAND AS THE SUNSHINE RETURNS TO END
THE HOLIDAY WEEKEND AND THE BEST PART OF THIS EARLY FALLISH STORY
IS THE COOLER TEMPS IN THE LACK OF LATE SUMMER SUNSHINE UNTIL
MONDAY. THE NEW WEEK WILL SEE SOME RAIN IN THE SEPTEMBER BUCKET AS
A SECONDARY AIR MASS PUSHES OUT OF THE CANADA AND DOWN THE MS
RIVER VALLEY KEEPING THE BELOW AVERAGE TEMPERATURES ON A ROLL. /24/

THE EXCEPTION OF THE TYR/GGG AND LFK TERMINALS BUT CONVECTION IS
FORECAST TO EXPAND TO INCLUDE THOSE TERMINALS AS WELL NEAR OR

CONVECTION AND NORTH OF THE CONVECTION RANGE FROM LOW MVFR TO LIFR
CONDITIONS WITH IN AND OUT IFR/MVFR VSBYS WITH THE MORE INTENSE

LFK TERMINAL BY AFTERNOON/EVENING. MAY SEE A SLOW IMPROVEMENT TO
CEILINGS ALONG THE I-20 CORRIDOR BUY LATER THIS AFTERNOON. DID
REINTRODUCE VCSH LATE TONIGHT THROUGH THE END OF THE TAF PERIOD AS
