...STRONG THUNDERSTORMS THIS AFTERNOON AND EVENING...

A LOW PRESSURE SYSTEM WILL MOVE FROM EASTERN SOUTH DAKOTA EAST TO
NORTHERN WISCONSIN TODAY...CAUSING ITS ASSOCIATED FRONT TO MOVE TOWARDS
THE AREA.  AHEAD OF THIS FRONT...STRONG SOUTHERLY FLOW WILL BRING VERY
WARM...HUMID AIR INTO THE REGION. BY MID AFTERNOON...THIS FRONT WILL
MOVE CLOSE ENOUGH TO THE AREA TO SERVE AS A FOCUS FOR THUNDERSTORMS AS
IT INTERACTS WITH UNSTABLE AIR MASS OVER THE AREA.  IT WILL CONTINUE TO
SHIFT SOUTHEAST INTO THE AREA INTO THE EVENING. THERE WILL BE SUFFICIENT
INSTABILITY AND WIND SHEAR FOR THE STORMS TO BECOME QUITE STRONG...WITH
THE MAIN THREAT BEING DAMAGING WINDS AND LARGE HAIL...THOUGH TORNADOS
ARE ALSO A POSSIBILITY.  LATER THIS EVENING AND OVERNIGHT...
THUNDERSTORMS REMAIN A POSSIBILITY AS THE FRONT SETTLES SOUTH TO DRAPE
FROM NEAR KANSAS CITY TO NEAR CHICAGO.  AS INSTABILITY DECREASES IN
THE EVENING AFTER SUNSET...THE THREAT CHANGES TO VERY HEAVY RAIN...
WHICH MAY LEAD TO LOCALIZED FLOODING.

THE FRONT WILL CONTINUE TO DROP SOUTH...AND ON THURSDAY WILL LAY ACROSS
NORTHERN MISSOURI INTO CENTRAL ILLINOIS.  IT WILL CONTINUE TO PROVIDE A
CHANCE FOR SHOWERS AND THUNDERSTORMS FOR THURSDAY THROUGH FRIDAY.

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND EVENING...MAINLY FOR
LOCATIONS ALONG AND NORTH OF HIGHWAY 34.
