FRONTAL WAVES EXIST ALONG STRONGLY CURVED AND SEGMENTED WARM FRONT
FROM THE SOUTH SHORE OF LAKE MI...ACROSS SCNTRL MI...TO THE ST.
CLAIR RIVER/WRN LAKE ERIE. TSTM COMPLEX NOW MOVING ACROSS ERN LOWER
MI APPEARS LINKED TO FRONTAL WAVE NOW MOVING ACROSS THE THUMB AREA.
A FEW SUPERCELLS HAVE BEEN CO-LOCATED WITH THIS IMPULSE. FARTHER
WEST...CONVECTIVE OVERTURNING AND HEAVY RAIN HAVE STABILIZED THE
AIRMASS OVER SRN LOWER MI BUT SLY WINDS AND WARM AIR ADVECTION AHEAD
OF THE MAIN LOW WERE RESULTING IN AIRMASS RECOVERY FROM NERN IL
ACROSS NRN IND. THIS AREA WILL CONTINUE TO BE MONITORED FOR
ADDITIONAL STORM DEVELOPMENT AS FORCING WITH THE UPPER TROUGH AND
SURFACE LOW MOVE EAST LATER THIS EVENING.

ADDITIONALLY...STRONG CELLS HAVE ERUPTED OFF THE WARM FRONT AND
MOVED OVER CNTRL LAKE MI OVER THE PAST HOUR. THIS ACTIVITY WILL
LIKELY MOVE ACROSS AREAS OF NRN LOWER MI...NORTH OF THE SURFACE WARM
