AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
105 PM CDT MON MAY 26 1997

MAIN PROBLEM TONIGHT IS THUNDERSTORM RE-DEVELOPMENT.

MCS HAS MOVED EAST OF FORECAST AREA AND FRONTAL BOUNDARY WAS FROM
NEAR BWG TO CGI AT NOON.  WITH FRONT FORECAST TO REMAIN QUASI STNRY
THROUGH TUESDAY AND PIECES OF ENERGY BREAKING OFF THE MAIN UPPER LEVEL
SYSTEM EJECTING EASTWARD WE ARE LIKELY TO SEE MORE BOUTS OF STORMS.

STAGE BEING SET TODAY WITH VERY UNSTABLE AIRMASS OVER SOUTHERN PART OF
AREA AS PARTIAL CLEARING HAS TAKEN PLACE.  HOWEVER...WE APPEAR TO BE IN
AN AREA OF SOME DOWNWARD MOTION BEHIND THE MCS.  MODELS DISPLAY THIS
WITH GENERALLY NVA ACROSS THE AREA THROUGH EVENING.  HOWEVER...AS PER
SPC MCD...BOUNDARIES DO EXIST AND EXPECT DEVELOPMENT THERE LATER.
ANOTHER SPOKE OF VORTICITY PROGGED TO CROSS THE REGION LATE EVENING/
OVERNIGHT AND THINK CHANCES OF ANOTHER MCS ARE HIGH.  SUGGEST USING
LIKELY POPS TONIGHT.
.
COULD SEE MORNING STORMS SUBSIDING WITH PERHAPS ANOTHER BREAK THEN
SCATTERED STORMS AGAIN BY AFTERNOON...ALL LEADING TO HIGH DAILY POP.

AT THIS TIME WILL NOT ARGUE WITH FWC TEMPERATURES.  WITH FRONT HOVERING
IN VICINITY WILL NEED TO SPLIT ZONES BASICALLY BY EXPECTED ^TEMP
GRADIENT.
