AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
235 PM EDT TUE JUN 5 2001

MAIN FORECAST PROBLEM THIS AFTN CONTINUES TO BE CHANCES FOR RAIN
THROUGH THE PERIOD.

AT 18Z WARM FRONT IS JUST NORTH OF FORECAST AREA (FA) IN SOUTHERN
IN. TEMPERATURES ACROS THE FA WERE IN THE 80S WITH DWPTS AROUND 70.

AVN SEEMS TO BE THE ODD MODEL OUT LATER IN THE FORECAST PERIOD BY
SWINGING FRONT THROUGH THE FA AND DRYING THE FA OUT FASTER THAN
EITHER THEN NGM OR ETA. WILL USE AN ETA/NGM BLEND THIS FCST.

WITH INSTABILITY ACROSS THE FA...WEAK VORT ACROSS SRN FA...AND WMFNT
VCNTY NRN FA...COULD BE SCTD CONVECTION THIS EVENING. ANOTHER CHANCE
FOR RAIN OCCURS LATER TONIGHT AND IN THE MORNING AS STORMS MAY MOVE
ALONG WARM FRONT TO THE N. 850 THETAE RIDGE MOVES OVER FA BY MORNING
AS WELL. WILL GO CHC POPS ALL AREAS.

WILL CONTINUE LIKELY POPS WED AND WED NIGHT ACROSS FA. STORMS IN THE
MORNING MAY LEAVE BOUNDARIES FOR MORE AFTN CONVECTION ACROSS FA.
ALSO...FRONT TO THE NORTH BEGINS TO MOVE SOUTH AGAIN LATE IN THE
DAY.  THIS FRONT WILL MOVE INTO NRN FA BY THU MORNING. WILL GO CHC
POPS THU ALL AREAS.

TEMPS WILL DEPEND ON CLOUD COVER AND ANY TSRA. FWC LOOKS DECENT AND
SEE NO REASON TO DEVIATE TOO MUCH FROM THOSE VALUES.

.SDF...NONE.
