Severe Thunderstorm Warning 189, NWS Wichita, KS

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE WICHITA KS
1150 AM CDT WED JUN 25 2003

SENDING A GRIDS/ZONE FCST UPDATE MAINLY TO INCREASE PRECIP CHANCES
OVER S-CNTRL AND SERN KS. AT 16Z THE COLD FRONT WAS ALONG A LINE
FROM JUST W OF MANHATTAN TO HUTCHINSON, TO JUST W OF MEDICINE LODGE.
THE FRONT WILL GRADUALLY SLOW A BIT THIS AFTERNOON AS IT ENCOUNTERS
STRONGER HEATING/MIXING, HOWEVER IT SHOULD BE EAST OF THE TURNPIKE
BY LATE AFTERNOON. VERY TROPICAL DWPTS ALONG AND AHEAD OF THE FRONT
AND PLENTY OF CLOUD COVER. THINK THE MAIN THREAT IS SHIFTING TO
LOCALLY HEAVY RAINFALL WITH ISOLATED STORMS PERHAPS PRODUCING
DOWNBURST WINDS/HAIL.
