EVENING OVER PARTS OF NORTHEAST AND WEST CENTRAL MISSOURI AN EAST
CENTRAL KANSAS...

TRIGGER THUNDERSTORMS AS IT MOVES SLOWLY SOUTHEAST. THE ATMOSPHERE
WILL CONTINUE TO BE VERY UNSTABLE THROUGH EARLY THIS EVENING AHEAD
OF THE FRONT. DUE TO WEAK ATMOSPHERIC WINDS...HAIL AND DAMAGING
WINDS ARE THE PRIMARY EFFECTS. IN ADDITION...DUE TO THE SLOW
MOVEMENT OF STORMS...HEAVY RAINFALL IS ALSO EXPECTED. THE STORMS
WILL DIMINISH THIS EVENING.

OUTLOOK: THUNDERSTORMS MAY RETURN LATE SATURDAY NIGHT AND THROUGH
