HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
600 AM CDT MON SEP 23 1996

...THUNDERSTORMS LIKELY TODAY...SOME POSSIBLY SEVERE...

FORECAST...TWO WAVES OF THUNDERSTORMS ARE EXPECTED TODAY. ONE IS
OCCURRING EARLY THIS MORNING AS THUNDERSTORMS MOVE EAST ACROSS
NORTHERN MISSOURI. THE SECOND IS FORECAST FOR LATE THIS AFTERNOON.
SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON IN PREPARATION FOR
THE SECOND ROUND OF STORMS. THE MAIN THREAT FROM THESE STORMS
APPEARS TO BE DAMAGING HAIL...ALTHOUGH STRONG WINDS AND TORRENTIAL
RAINS MAY ALSO BE SUFFICIENT TO CAUSE DAMAGE.

DISCUSSION...SHOWERS AND THUNDERSTORMS WERE DEVELOPING ALONG AND
NEAR A WARM FRONT THAT EXTENDED FROM EXTREME NORTHEAST KANSAS
ACROSS FAR NORTHERN MISSOURI. A FEW THUNDERSTORMS DEVELOPED ALONG A
WEAK SURFACE BOUNDARY FURTHER SOUTH OVER THE KANSAS CITY METRO
AREA. LOW LEVEL MOISTURE CONTINUES TO STREAM NORTHWARD INTO THE
AREA ON STRONG LOW-LEVEL WINDS. A SURFACE COLD FRONT IS EXPECTED TO
MOVE ACROSS THE AREA LATE TODAY...PROVIDING A PRIME FOCUS FOR
AFTERNOON THUNDERSTORM DEVELOPMENT.. THUNDERSTORMS ARE EXPECTED TO
DEVELOP ALONG AND AHEAD OF THE COLD FRONT AS IT MOVES THROUGH THE
AREA.
