DISCUSSION
ISSUED AT 225 AM CDT MON OCT 6 2025
A COLD FRONT OVER THE PLAINS AND VORT MAXES ASSOCIATED WITH A
BROAD MID-LEVEL TROUGH WILL BRING A PERIOD OF WET WEATHER TO THE
FA TODAY INTO TUESDAY. HRRR MODEL SOUNDINGS SHOW A 30 KT
NOCTURNAL LLJ AROUND 925 MB THAT WILL SUPPORT A ROBUST MOISTURE
TRANSPORT. THE NAEFS AND ECMWF ESAT NOW BOTH INDICATE 10-YEAR
RETURN INTERVALS FOR PWATS REACHING 1.75 TO 2.00 INCHES. MEAGER
INSTABILITY AND SHEAR CONTINUE TO FAVOR HEAVY RAINFALL BEING THE
MAIN CONCERN WITH THE BULK OF PCPN FALLING OVER A 36 HOUR
PERIOD. THE GENERAL CONSENSUS IS FOR SHOWERS AND THUNDERSTORMS
TO QUICKLY DEVELOP THIS MORNING AND TURN MORE WIDESPREAD IN THE
THE AFTERNOON AND EVENING. SOMEWHAT OF A LULL WILL THEN OCCUR
AT NIGHT BEFORE THE MOST NUMEROUS PCPN THAT WILL POSE THE
GREATEST RISK OF HEAVY RAIN OCCURS TUESDAY MORNING INTO EARLY
TUESDAY AFTERNOON.
THE 0Z HREF PMM FOR QPF IS MORE CONCERNING IN SHOWING AN AXIS
OF 3.0 TO 5.0 INCHES ACROSS THE KENTUCKY PENNYRILE WHILE 0.5 TO
2.0 INCHES OVER THE REMAINDER OF THE FA DUE TO A SHARP GRADIENT.
THE HRRR AND ARW IN PARTICULAR IS HINTING AT THE POTENTIAL FOR
EVEN LOCALLY HIGHER AMOUNTS. OVERALL, THE RISK OF FLOODING HAS
INCREASED DUE TO THE WETTER SIGNAL WITH A SLIGHT ERO NOW
PROGGED BY THE WPC. THE GREATEST CONCERN WILL BE PRIMARILY OVER
THE KENTUCKY PENNYRILE TUESDAY MORNING WITH TRAINING CONVECTION
ALONG A BAROCLINIC ZONE AS FRONTOGENESIS INCREASES WITH A COLD
FRONT APPROACHING FROM THE WEST. ALTHOUGH THE RISK IS LOWER,
MINOR ISOLATED FLOODING ISSUES DUE TO RUNOFF WILL ALSO BE
POSSIBLE ACROSS THE REST OF THE FA. OVERALL, THE GENERAL
CONSENSUS IS NOW FOR 1 TO 3 INCHES OF RAINFALL OVER MUCH OF THE
REGION, WITH LOCALLY HIGHER AMOUNTS.
TEMPERATURES WILL BE MUCH COOLER FROM THE THICK CLOUD COVER TO START
OFF THE WEEK WITH HIGHS ONLY IN THE 70S. LOWERED NBM TEMPS FOR TODAY
WITH A BLEND OF THE CONSSHORT AND HREF THAT IS MORE IN LINE WITH MOS
GUIDANCE. AFTER THE COLD FRONT SWEEPS THROUGH TUESDAY NIGHT,
TEMPERATURES WILL REMAIN NEAR TO SLIGHTLY BELOW NORMAL THROUGH THE
REMAINDER OF THE WEEK WITH 850 MB TEMPS AROUND 8 TO 10C. A 1030 TO
1034 MB SFC HIGH PRESSURE OVER THE GREAT LAKES REGION WILL ALSO
SUPPORT AMPLE DRY WEATHER, SUPPRESSING ANY MOISTURE TO THE SOUTH AS
A 500 MB LONGWAVE TROUGH DIGS ACROSS THE EASTERN CONUS NEXT
WEEKEND.
