115 PM CDT THU JUN 14 2001
TWO AREAS OF THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND EVENING
AS A COLD FRONT APPROACHES IOWA FROM THE WEST. THUNDERSTORMS ARE
LIKELY TO PRODUCE SMALL HAIL AND VERY HEAVY RAIN TO THE SOUTHEAST

EXPECTED TO BECOME MODERATELY UNSTABLE OVER WESTERN IOWA AS SOUTH
WINDS TRANSPORT MOISTURE FROM THE KANSAS CITY AREA. BY LATE
AFTERNOON...SCATTERED THUNDERSTORMS SHOULD DEVELOP IN A NORTH TO
SOUTH LINE OVER WESTERN IOWA AHEAD OF THE FRONT. THE STRONGEST
STORMS ARE EXPECTED TO BE OVER SOUTHWEST IOWA...CLOSER TO THE
INSTABILITY AND INFLOW. SOME STORMS MAY PRODUCE LARGE HAIL AND
HEAVY RAIN...ALONG WITH GUSTY WINDS. THUNDERSTORMS IN WESTERN IOWA
SHOULD GRADUALLY WORK INTO CENTRAL IOWA DURING THE EVENING HOURS AS
THE FRONT MOVES EAST...WHILE TRAINING OF THUNDERSTORMS AND REPEAT
HEAVY RAINS ARE MORE LIKELY EAST AND SOUTHEAST OF DES MOINES.
