...SEVERE THUNDERSTORMS POSSIBLE THIS AFTERNOON AND THIS EVENING...

FORECAST: WIDELY SCATTERED THUNDERSTORMS WILL LIKELY DEVELOP OVER
EXTREME NORTHWESTERN PORTIONS OF MISSOURI EARLY THIS AFTERNOON.
THUNDERSTORMS WILL LIKELY FORM A BROKEN LINE OF STORMS AND DROP TO
THE SOUTHEAST DURING THE AFTERNOON. AS THIS LINE DROPS TO THE SOUTH...
STORMS WILL INCREASE IN COVERAGE AND INTENSITY. SOME STORMS WILL BE
CAPABLE OF PRODUCING WIND GUSTS IN EXCESS OF 70 MPH. LARGE HAIL WILL
ALSO BE A THREAT. SEVERE STORMS WILL BE MOST LIKELY BETWEEN 3 PM AND
9 PM.

DISCUSSION:  A COLD FRONT STRETCHED FROM NEAR LA CROSSE WISCONSIN TO
OMAHA TO HILL CITY KANSAS LATE THIS MORNING. THIS FRONT WILL MOVE TO
THE SOUTH DURING THE AFTERNOON. THIS FRONT AND OTHER BOUNDARIES
CAUSED BY THUNDERSTORMS OVERNIGHT WILL TRIGGER STORM DEVELOPMENT
THIS AFTERNOON. A VERY DEEP LAYER OF MOISTURE OVER THE REGION WILL
CONTRIBUTE TO SEVERE STORM POTENTIAL. LOCALIZED DAMAGING WINDS AND
LARGE HAIL ARE THE MAIN THREAT.
