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.
