AREAS AFFECTED...SCNTRL WI

CONCERNING...SEVERE THUNDERSTORM WATCH 514...

VALID 232334Z - 240130Z

WIDESPREAD WIND DAMAGE WILL BE LIKELY AS A BOW ECHO RACES SEWD AT 50
KT ACROSS SCNTRL WI. A NEW WW IS BEING ISSUED.

SFC ANALYSIS SHOWS A SFC LOW ACROSS NW WI WITH A WARM FRONT
EXTENDING SEWD ACROSS SCNTRL WI INTO THE CHICAGO AREA. A BOW ECHO IS
CURRENTLY NEAR THE SFC LOW AND SHOULD TRACK SEWD ALONG THE WARM
FRONT OVER THE NEXT SEVERAL HOURS. SFC DEWPOINTS ARE IN THE LOWER
60S F ACROSS SERN WI AND THE BOW ECHO SHOULD CONTINUE TO ORGANIZE AS
IT MOVES INTO INCREASING LOW-LEVEL MOISTURE. THE LINE IS JUST AHEAD
OF A 80 KT MID-LEVEL SPEED MAX. AS THIS FEATURE PUNCHES SEWD...DEEP
LAYER SHEAR WILL INCREASE. IN ADDITION...OBJECTIVE ANALYSIS SHOWS
INCREASING MID-LEVEL LAPSE RATES WHICH WILL ALSO AID INTENSIFICATION
OF THE LINE. AS A RESULT...WIDESPREAD WIND DAMAGE IN A NARROW
CORRIDOR FROM NW TO SE APPEARS LIKELY ACROSS SCNTRL WI.
