AREAS AFFECTED...NORTHEAST ILLINOIS INTO WESTERN INDIANA
CONCERNING...SEVERE THUNDERSTORM WATCH 455...
VALID 042051Z - 042215Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 455
CONTINUES.
SUMMARY...LOCALLY DAMAGING WIND GUSTS REMAIN POSSIBLE FROM
EAST-CENTRAL ILLINOIS INTO WESTERN INDIANA. A NEW WATCH MAY NOT BE
NEEDED DEPENDING ON TRENDS.
DISCUSSION...CONVECTION INCREASED AHEAD OF THE MCV MOVING OUT OF IA,
BUT HAS GENERALLY MOVED SLOWLY, PRODUCING HEAVY RAIN. THE AIR MASS
ACROSS THE REGION CONTINUES TO HEAT AND DESTABILIZE, AND REMAINS
SUFFICIENT FOR AT LEAST LOCALIZED SEVERE WIND GUSTS. RECENT RADAR
TRENDS HAVE SHOWN SOME BOWING STORMS, WHICH MAY BE CAPABLE OF
DAMAGING GUSTS. UNLESS STORMS BECOME BETTER ORGANIZED, AN ADDITIONAL
WATCH MAY NOT BE NEEDED DOWNSTREAM.
