HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
100 PM CDT THU JUN 1 2000

...SEVERE THUNDERSTORMS POSSIBLE TONIGHT...

FORECAST: STRONG TO SEVERE THUNDERSTORMS ARE POSSIBLE TONIGHT ACROSS
EXTREME EASTERN KANSAS AND NORTHWEST MISSOURI. THUNDERSTORMS ARE
EXPECTED TO DEVELOP AS EARLY AS 6 PM ALONG AND WEST OF I-35 FROM
BETHANY SOUTHWESTWARD THROUGH THE KANSAS CITY METRO AREA AND BETWEEN
7 AND 9 PM FURTHER TO THE EAST. DAMAGING WINDS AND HAIL ARE THE
PRIMARY SEVERE WEATHER THREATS ACROSS THE OUTLOOK AREA. LOCALLY
HEAVY RAINFALL IS ALSO A POSSIBILITY WITH STORMS TONIGHT. THE THREAT
OF SEVERE THUNDERSTORMS SHOULD DIMINISH BY MIDNIGHT ALONG AND WEST
OF I-35 AND LINGER UNTIL 2-4 AM IN LOCATIONS TO THE EAST. EMERGENCY
MANAGERS SHOULD PREPARE THIS AFTERNOON FOR POSSIBLE SPOTTER
ACTIVATION TONIGHT.

DISCUSSION: A COLD FRONT OVER SOUTHEAST NEBRASKA THIS AFTERNOON WILL
SLOWLY SWEEP ACROSS THE OUTLOOK AREA TONIGHT. VERY MOIST AND
UNSTABLE AIR IN PLACE OVER THE REGION AHEAD OF THE FRONT WILL
PROVIDE THE NECESSARY FUEL FOR THUNDERST]ORM DEVELOPMENT THIS EVENING
AS LOW LEVEL WINDS CONVERGE JUST AHEAD OF AND WITH THE FRONTAL
PASSAGE. COOLER AND MORE STABLE AIR WILL FOLLOW THE FRONT LATER
TONIGHT.
