AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
300 AM EDT THU JUNE 21 2001

SHOWERS AND SCATTERED THUNDERSTORMS ACROSS WESTERN KENTUCKY AND
SOUTHERN INDIANA HAVE BEEN SLOW TO MOVE INTO OUR COUNTY FORECAST
AREA. I FEEL THIS PRECIPITATION WILL REMAIN ALONG AND NORTH OF THE
OHIO RIVER THIS MORNING AS IT DIMINISHES.

MODELS AREA IN AGREEMENT ON BRINGING A VIGOROUS S/W CURRENTLY OVER
SOUTH DAKOTA INTO THE UPPER OHIO VALLEY BY THIS EVENING. AN AREA OF
LOW PRESSURE WILL MOVE ALONG A WEAK FRONTAL BOUNDARY STRETCHED ALONG
THE OHIO RIVER AS WELL. SHOWERS AND THUNDERSTORMS WILL OVERSPREAD
THE CFA THIS AFTERNOON AND CONTINUE INTO THE EVENING. SOME OF THE
STORMS MAY BECOME SEVERE AND THE SPC HAS INDICATED A SLIGHT RISK
EXISTS FOR OUR CFA. THE BEST CHANCE FOR RAIN WILL REMAIN ALONG AND
NORTH OF THE OHIO RIVER AND SOME LOCATIONS MAY SEE AN ADDITIONAL
INCH TO ONE AND A HALF INCHES OF RAIN IN HEAVIER THUNDERSTORMS.

A SECOND S/W WILL DROP INTO THE EASTERN U.S. TROF ON FRIDAY BUT
MOISTURE WILL BE LIMITED AND I DO NOT EXPECT ANY MORE PRECIPITATION
AFTER TONIGHT.

MOS TEMPERATURES LOOK GOOD AND WILL REMAIN TRICKY DEPENDING ON CLOUD
COVER.
