   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.
