Area forecast discussion, Jul 21, 1:00 AM CST, 10 hours 52 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 200 AM CDT FRI JUL 21 2006 .DISCUSSION... THE BRIEFING WAS THAT THE GFS WAS SCREAMING CONVECTIVE FEEDBACK BUT IT SURE IS HANDLING NEAR TERM CONVECTION WELL...BETTER THAN WRF. MAIN COMPLEX OF TSMS IN VCNTY OF SURFACE LOW...SHOULD CONT ESE SLIDE AND AFFECT MAINLY NERN PTNS PAH FA EARLY THIS AM. AFTER THAT IS WHEN MAYBE THE FEEDBACK COMES INTO PLAY AND AS SUCH WELL USE GFS W/ CAUTION AND IN TANDEM W/ WRF. BOTH MODELS DIVE FRONT SOUTH ACROSS FA BY LATE FRIDAY-FRIDAY NIGHT...WITH CONVECTION DEVELOPING JUST TO THE WEST DURING THE HEAT OF THE DAY AND EXPANDING EAST OVER ENTIRE QUAD STATE OVERNIGHT. AS A RESULT WEVE UPPED POPS TO CATEGORICAL FRI NIGHT W/LOWEST MODEL MOS OUTPUT OF ANY KIND IN THE HIGH LIKELY CATEGORY. THE FRONT WILL BE DRIVEN THRU BY THE PASSAGE OF THE UPPER TROF FAIRLY EARLY IN THE DAY SATURDAY...THEREFORE WEVE ELIMINATED POPS AFT 18Z. GFS IS FASTER THAN WRF BUT BOTH ARE QUICK AND HAVE BEEN TRENDING FASTER SO WERE REASONABLY COMFORTABLE EXITING PCPN BY THEN. CERTAINLY NUMERICAL MOS OUTPUT OF ALL MODELS SUPPORTS DOING SO. AFTER THAT THERE IS LITTLE CHANGE OTHER THAN THE ELIMINATION OF A SLGT CHANCE TUE. WE CONSIDERED SHIFTING IT TO TUE NIGHT BUT THEN WE REALLY COULDNT RULE OUT 20 POPS DEFINITIVELY FOR SEVERAL TIME PERIODS. GIVEN THE DRY POST FRONTAL REGIME IN THE NEAR TERM...WE DECIDED TO JUST WAIT TIL THE MODELS BEGIN TO OUTPUT A MORE CONDUCIVE TO PCPN PATTERN. THIS LOOKS LIKE IT COULD BE COMING TOGETHER BY DAY 7 BUT WELL FOLLOW THE USUAL ROUTINE AND WAIT FOR SOME CONSISTENCY ON THIS OUTPUT BEFORE INTRODUCING IT. NEAR TERM NGM MOS LOOKS GOOD BLENDED INTO MAV/MEX MOS AND THE COLLABORATIVE PICTURE IN THE MEDIUM-LONG RANGE. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE. IN...NONE. &&
