HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
1241 PM CDT THU APR 5 2001

...SEVERE THUNDERSTORMS ARE POSSIBLE TODAY AND TONIGHT...

FORECAST: THUNDERSTORMS WILL DEVELOP ACROSS NORTHEAST KANSAS AND
NORTHWEST AND NORTH CENTRAL MISSOURI THIS AFTERNOON. SOME OF THESE
STORMS COULD BECOME SEVERE POSSIBLY PRODUCING LARGE HAIL AND
DAMAGING WINDS.

DISCUSSION: A WARM FRONT ACROSS NORTHERN KANSAS AND NORTHERN
MISSOURI WILL SERVE AS A FOCAL POINT FOR THUNDERSTORM DEVELOPMENT
THIS AFTERNOON AND EVENING. VERY WARM...HUMID AIR WILL COUPLE WITH
AN UPPER LEVEL STORM SYSTEM TO HELP PRODUCE AN UNSTABLE ATMOSPHERE.
THE CURRENT WIND FIELD AT THE SURFACE AND ALOFT SUPPORT THE
POSSIBILITY THAT SOME STORMS COULD ROTATE. THE MAIN THREATS FROM
THESE STORMS WILL BE LARGE HAIL AND DAMAGING WINDS.

OUTLOOK:  AN OUTBREAK OF SEVERE WEATHER IS LIKELY LATE FRIDAY
AFTERNOON AND FRIDAY EVENING AS AN UPPER LEVEL STORM SYSTEM CROSSES
THE PLAINS.  THUNDERSTORMS WILL AGAIN BE POSSIBLE ON SUNDAY AND THE
BEGINNING OF THE WORK WEEK.
