Severe Thunderstorm Warning 19, NWS Louisville, KY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
230 PM EST FRI MAR 15 2002

A VERY INTERESTING FORECAST IS SHAPING ACROSS THE LOWER OHIO VALLEY
FOR THE NEXT 48 HOURS. SEVERAL PERIODS OF RAIN SHOULD HELP ALLEVIATE
RAINFALL DEFICIENT ACROSS THE REGION. AT 19Z A COLD FRONT STRETCHED
FROM JUST SOUTH OF PADUCAH ACROSS DUBOIS COUNTY IN SOUTHERN INDIANA
AND NORTHEAST TO EXTREME NORTHWEST OHIO. SOUTH OF THE FRONT
TEMPERATURES WERE IN THE MID AND UPPER 60S WITH READINGS TO THE WEST
OF THE FRONT IN THE UPPER 40S AND LOWER 50S.

ALTHOUGH THE MODELS ARE IN GENERAL AGREEMENT ON THE SYNOPTIC PATTERN
EXPECTED OVER THE NEXT SEVERAL DAYS THE TRACK AND STRENGTH OF S/W
ENERGY MOVING THROUGH THE MID LEVEL SOUTHWEST FLOW DIFFERS. THE
FIRST WAVE IS EXPECTED ALONG THE FRONT OVERNIGHT. THE FRONT SHOULD
DROP INTO CENTRAL KENTUCKY THIS EVENING BEFORE BECOMING STATIONARY
AS THE WEAK LOW MOVE UP FROM ARKANSAS. PERIODS OF HEAVY RAIN WILL BE
POSSIBLE ALONG THE FRONT OVERNIGHT AND A LARGE AREA OF BETWEEN 1/2
AND 1 INCH AMOUNTS ARE EXPECTED OVER THE SOUTHERN AND EASTERN
PORTIONS OF THE CFA.

THE THREAT OF SEVERE WEATHER LOOKS TO COME FROM EITHER MARGINALLY
SEVERE WINDS JUST AHEAD OF THE FRONT OR HAIL WITH THE ELEVATED
STORMS TO THE NORTH AND WEST.

THE MID LEVEL SOUTHWEST FLOW WILL REMAIN IN PLACE THROUGH THE
WEEKEND AND THE SURFACE FRONT WILL BECOME MORE DIFFUSE ACROSS
SOUTHERN KENTUCKY AND TENNESSEE. A SECOND WAVE WILL MOVE ACROSS THE
REGION SATURDAY NIGHT AND SUNDAY WITH A THIRD EXPECTED ON MONDAY.

BECAUSE OF THE TIMING DIFFERENCES IN THE MODELS MOS TEMPERATURES
BEGIN TO VARY AFTER 36 HOURS.

.SDF...NONE.
