   Areas affected...Southeast Lower Michigan

   Concerning...Severe Thunderstorm Watch 466...

   Valid 272155Z - 272300Z

   The severe weather threat for Severe Thunderstorm Watch 466
   continues.

   SUMMARY...Isolated wind-damage threat will continue until about 23z.

   DISCUSSION...A broken band of storms is moving eastward across
   southeast Lower MI, with the effective front marked by the aggregate
   outflow boundary coincident with the storms.  Unidirectional wind
   profiles from the west-southwest around 30 kt, precipitation loading
   with moderate buoyancy, and lingering steep low-level lapse rates
   suggest some continuing potential for isolated wind damage prior to
   the convection moving into ON by about 23z.  Thereafter, the severe
   threat will have ended and the watch will likely be canceled prior
   to the scheduled 01z expiration.
