AREAS AFFECTED...ERN WI...FAR NE IL...WRN LAKE MICHIGAN

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 242324Z - 250100Z

THE SEVERE THREAT SHOULD INCREASE ACROSS ERN WI...FAR NE IL AND WRN
LAKE MICHIGAN OVER THE NEXT FEW HOURS AS A LINE MOVES IN FROM THE
WEST. A WW SHOULD BECOME NECESSARY EARLY THIS EVENING ACROSS THE
REGION.

A LINEAR MCS IS CURRENTLY ONGOING IN SCNTRL WI AND SHOULD CONTINUE
MOVING EWD...AFFECTING THE WRN SHORELINE OF LAKE MICHIGAN LATER THIS
EVENING. THE AIRMASS AHEAD OF THE LINE IS MODERATELY UNSTABLE
SUGGESTING THE LINE SHOULD CONTINUE TO BE SUSTAINED THROUGH THE
EVENING. IN ADDITION...OBJECTIVE ANALYSIS SHOWS A 50 KT MID-LEVEL
JET NOSING INTO THE REGION FROM THE SOUTHWEST WHICH IS ENHANCING
VERTICAL SHEAR PROFILES. REGIONAL WSR-88D VWPS SHOW 40-45 KT OF 0-6
KM SHEAR SUGGESTING SUPERCELLS WILL CONTINUE TO BE POSSIBLE EMBEDDED
IN THE LINE. ALTHOUGH SOME WEAKENING OF THE LINE MAY OCCUR AS THE
LINE APPROACHES THE MORE STABLE AIR OVER WRN LAKE MICHIGAN...LARGE
HAIL AND WIND DAMAGE MAY CONTINUE WITH THE STRONGER CELLS UNTIL THE
LINE MOVES OFFSHORE.
