CENTRAL KENTUCKY AND SOUTH-CENTRAL INDIANA SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE LOUISVILLE KY
530 AM EST WED FEB 20 2002

THE STORM PREDICTION CENTER HAS INDICATED THAT A SLIGHT RISK OF
SEVERE THUNDERSTORMS EXISTS ACROSS CENTRAL KENTUCKY AND SOUTH-CENTRAL
INDIANA FOR THIS AFTERNOON.

DEVELOPING LOW PRESSURE...LOCATED OVER NORTHERN ILLINOIS...WILL MOVE
TO THE GREAT LAKES REGION TONIGHT. A COLD FRONT IN ASSOCIATION WITH
THE LOW PRESSURE WILL MOVE ACROSS THE AREA THIS AFTERNOON. AHEAD OF
THE COLD FRONT...STRONG WINDS IN THE LOW LEVELS OF THE ATMOSPHERE
WILL DRAW MOIST AND UNSTABLE AIR INTO CENTRAL KENTUCKY AND SOUTHERN
INDIANA. MANY PRIME INGREDIENTS ARE IN PLACE FOR THE DEVELOPMENT OF
SEVERE WEATHER. HOWEVER...EXTENSIVE CLOUD COVER WILL LIMIT THE
AMOUNT OF HEATING TODAY. BECAUSE OF THIS...ISOLATED STRONG
THUNDERSTORMS WITH DAMAGING STRAIGHT LINE WINDS...AND SMALL HAIL...
WILL BE POSSIBLE.

BECAUSE OF THE PROXIMITY TO THE STRENGTHENING LOW PRESSURE...
SOUTHWEST WINDS TODAY WILL BE 20 TO 30 MPH...WITH HIGHER GUSTS AT
TIMES. CITIZENS SHOULD PREPARE BY TYING DOWN LOOSE HOUSEHOLD ITEMS.
MOTORISTS SHOULD ANTICIPATE THE STRONG WINDS...ESPECIALLY IF DRIVING
A VEHICLE WITH A HIGH CENTER OF GRAVITY...AS CROSS WINDS WILL MAKE
IT DIFFICULT TO NAVIGATE.

THIS IS A PRELIMINARY OUTLOOK. STAY TUNED TO NOAA WEATHER RADIO FROM
THE NATIONAL WEATHER SERVICE...OR THE LOCAL MEDIA...FOR THE LATEST
INFORMATION ON THIS WEATHER SITUATION. SKYWARN SPOTTER ACTIVATION IS
NOT ANTICIPATED AT THIS TIME.
