AREAS AFFECTED...LOWER MI

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 132355Z - 140130Z

...STRONG THUNDERSTORMS WILL MOVE INTO NWRN LOWER MI BY 01Z.  WW MAY
BE REQUIRED...

WELL DEFINED VORT CENTER HAS EVOLVED IN CONJUNCTION WITH MCS OVER
CNTRL WI.  LEADING EDGE OF THIS ACTIVITY IS SPREADING NEWD AT
ROUGHLY 40-45KT ACROSS LAKE MI.  RECENT REPORTS SUGGEST THIS
CONVECTION HAS PRODUCED DAMAGING WINDS ACROSS ERN WI...AND LOW LEVEL
LAPSE RATES REMAIN SUFFICIENTLY STEEP DOWNSTREAM TO MAINTAIN ONGOING
ACTIVITY.  THERE IS SOME CONCERN WITH DIURNAL COOLING AND WEAKENING
INSTABILITY THAT SQUALL LINE WILL GRADUALLY WEAKEN WITH TIME. 
HOWEVER...RADAR TRENDS SUGGEST THIS HAS YET TO COMMENCE.  WW MAY BE
REQUIRED IF CONVECTION DOES NOT BEGIN TO DECREASE IN INTENSITY.
