THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL KENTUCKY AND SOUTH
CENTRAL INDIANA.

.DAY ONE...OVERNIGHT.

A WARM FRONT MOVED THROUGH THE OUTLOOK AREA DURING THE EVENING,
LEAVING BEHIND A MORE HUMID AND UNSTABLE AIRMASS. THIS ALONG WITH AN
APPROACHING UPPER LEVEL DISTURBANCE, WILL BE ENOUGH TO TRIGGER SOME
SCATTERED THUNDERSTORMS THROUGH THE OVERNIGHT HOURS. THE HIGHEST
CHANCES FOR STORMS EXIST NORTHWEST OF A BOWLING GREEN TO LEXINGTON
LINE. DUE TO RELATIVELY COLD TEMPERATURES ALOFT, LARGE HAIL IS
POSSIBLE OUT OF THESE STORMS, ALONG WITH HIGH WIND GUSTS SHOULD
THESE STORMS ORGANIZE INTO LINES. REMEMBER THAT DEADLY LIGHTNING IS
ALWAYS A THREAT ANYTIME THUNDERSTORMS ARE NEARBY.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

WITH SURFACE LOW PRESSURE IN THE VICINITY, SCATTERED THUNDERSTORMS
WILL AGAIN DOT THE AREA THURSDAY, WITH THE POTENTIAL FOR LARGE HAIL
AND HIGH WINDS ACROSS THE OUTLOOK AREA, WHERE THE STORM PREDICTION
CENTER HAS FORECAST A SLIGHT RISK OF SEVERE STORMS.

UNSETTLED WEATHER WILL RETURN OVER THE WEEKEND, AS ANOTHER LOW
PRESSURE SYSTEM HEADS OUR WAY. AS A RESULT, SEVERAL ROUNDS OF
THUNDERSTORMS WILL BE POSSIBLE THEN. HOWEVER, IT IS TOO SOON TO
CONFIDENTLY PREDICT SEVERE THUNDERSTORM POTENTIAL OVER THE WEEKEND.

.SPOTTER INFORMATION STATEMENT...
