Area forecast discussion, Jun 22, 1:53 AM CDT, 1 hour 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
200 AM CDT SUN JUN 22 1997

MAIN FORECAST PROBLEM IS CONVECTIVE POTENTIAL NEXT 24 HOURS. 06Z KPAH
88D LOOPS INDICATED AN OUTFLOW BOUNDARY MOVED SOUTH INTO TENNESSEE.
AIR HAS STABILIZED ACROSS WRN KENTUCKY/SOUTHERN ILLINOIS/SW INDIANA
FOLLOWING PASSAGE OF THE OUTFLOW BOUNDARY. MAIN CONCERN IS THAT
SOUTHWEST LOW LEVEL INFLOW IS OVERRUNNING THE RAIN COOLED AIR MASS
OVER EASTERN MISSOURI. THIS IS CAUSING REGENERATION OF THE MCS ALONG
THE MISSISSIPPI RIVER. THIS PROCESS COULD RESULT IN A FLASH FLOOD
THREAT FOR PORTIONS OF SE MISSOURI THIS MORNING...WHERE 1 TO 2 INCHES
OF RAIN FELL BY 06Z.

IN THE LONGER RANGE...MODELS BUILD A DEEP LAYERED RIDGE EASTWARD ACROSS
THE FA THIS AFTERNOON AND TONIGHT. THIS SHOULD DECREASE THE THREAT OF
ANOTHER LARGE MCS OVER THE FORECAST AREA. 500 MB TEMPS ARE FORECAST TO
WARM A DEGREE OR TWO BY 06Z MONDAY. WOULD STILL EXPECT SOME SCATTERED
STORMS THIS AFTERNOON AND EVENING WITH LOW LEVEL BOUNDARIES FLOATING
AROUND. MCS DEBRIS OVER EASTERN SECTIONS OF THE FA SHOULD CONTINUE TO
THIN OUT AND DISSIPATE THIS MORNING...ALLOWING FOR SOME SUNSHINE.

TEMPS ARE A BIT OF A PROBLEM BECAUSE OF MCS ACTIVITY <LINGERING
ACROSS THE REGION. FWC TEMPS MATCH PERSISTENCE PRETTY WELL...AND
LOOK GOOD MOST PLACES. MAY WANT TO CUT TEMPS BACK ACROSS SE
MISSOURI WHERE HEAVY RAIN IS OCCURRING.
