AREAS AFFECTED...NRN/CNTRL WI...WRN U.P. OF MI
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 032033Z - 032200Z
LATEST VIS IMAGERY SUGGESTS ELEVATED CONVECTION ALONG ERN EDGE OF
STRONG CAP MAY BE GRADUALLY INTENSIFYING OVER SCNTRL MN. ALTHOUGH
ECHOES ARE WEAK WITH THIS CONVECTION...THERE IS A NOTABLE WIND SHIFT
WHICH SUPPORTS A MORE SUSTAINED ORGANIZED UPDRAFT. THIS ACTIVITY IS
MOVING RAPIDLY NEWD AT ROUGHLY 45-50KT TOWARD A FAIRLY
MOIST/UNSTABLE ENVIRONMENT OVER CNTRL/NRN WI WHERE INTENSIFICATION
MAY OCCUR. WHILE INHIBITION REMAINS STRONG WITHIN THE WARM
ADVECTION ZONE OVER WI...SUSTAINED ASCENT MAY ULTIMATELY LEAD TO
SUFFICIENT COOLING ALONG THE EDGE OF THE CAP FOR DEEPER UPDRAFTS TO
ROOT INTO MOIST BOUNDARY LAYER. IF SO...SUPERCELL STRUCTURES
CAPABLE OF PRODUCING LARGE HAIL AND EVEN TORNADOES ARE POSSIBLE. WW
MAY BE NEEDED ACROSS THIS REGION TO ACCOUNT FOR THIS INCREASING
SEVERE POTENTIAL.
