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.
