SATELLITE ANALYSIS AND TRENDS...VIS AND IR IMAGERY SHOW TO AREAS OF
MOD TO HVY CNVTN. ONE IS A NARROW BAND EXTENDING FM VCNTY OF JKL ENE
ACRS THE KY/WV BORDER. THE OTHER AREA IS BROADER..ALSO WARM TOP..WHICH
CONSISTS OF EMBEDDED HEAVY CLUSTERS OVER SE KY TO THE SW VA BORDER AND
EXTENDS TO SE TN. CURRENT IR/VIS/WV TRENDS SUGGEST THAT THESE TWO AREAS

DUE TO WARM TOP NATURE OF THE CNVTN STLT ESTIMATES ARE DIFFICULT
TO ASCERTAIN ATTM. HOWEVER...WITH DEW POINTS IN THE 60S/PW'S AROUND
1.4-1.5"..HVY RAIN BURSTS CAN OCCUR IN SHORT PERIODS OF TIME..ESP WITH
MERGERS. 0.5-1" IN AN HR CAN OCCUR..WITH SOME LOCALIZED 1"+ IN AN HR PSBL.
.
WV IMAGERY SHOW UPPR FLOW BACKING IN RESPONSE TO SW-NE ORIENTED SHORT
WAVE NW OF THE DISCUSSION AREA. THIS SUGGESTS THAT WHILE THERE IS SOME
EWD PROGRESSION OF THE CNVTN NOW..THERE MAY BE SOME SLOWING DOWN LATER ON.
