AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
305 PM EDT MON AUG 4 1997

SECOND SHORT WAVE DIVING SOUTHEAST FROM WESTERN LAKES WILL HELP TO
CARVE OUT UNSEASONABLY DEEP TROF OVER EASTERN U.S. MOST OF
THUNDERSTORM ACTIVITY SO FAR HAS BEEN ASSOCIATED WITH FIRST SHORT WAVE
AND PRE-FRONTAL TROF. WE ARE STILL SEEING SOME DEVELOPMENT ALONG
BOUNDARIES FROM EARLIER CONVECTION. UNTIL WE CAN GET FRONT THROUGH
WILL NEED TO KEEP A CHANCE POP FOR SOUTHEASTERN KY EARLY PART OF FIRST
PERIOD.

WITH SHORT WAVE...INSTABILITY AND UPSLOPE FLOW ON TUESDAY COULD SEE
SOME THUNDERSHOWERS NEAR VA BORDER...BUT FOR NOW PREFER DRY FORECAST
FOR TUESDAY.

UNSEASONABLY COOL AIR TO MOVE INTO REGION...AND FWC TEMPERATURES LOOK
PRETTY GOOD.
