Areas affected...Southern Lower Michigan...northeast Indiana...and
northwest Ohio

Concerning...Severe Thunderstorm Watch 552...

Valid 270002Z - 270130Z

The severe weather threat for Severe Thunderstorm Watch 552
continues.

SUMMARY...Strong to locally severe convection will spread across
southern lower MI and northeast Indiana/northwest Ohio early this
evening. Gusty winds remain the primary risk.

DISCUSSION...Progressive short-wave trough has advanced to southwest
lower MI/northern IN early this evening. Convection has recently
expanded in areal coverage ahead of this feature along the back edge
of earlier complex of storms. Low-level warm advection appears to be
instrumental as modest southwesterly flow is noted atop the
aforementioned rain-cooled air mass. Majority of convection is
likely slightly elevated in nature and should remain concentrated
along/north of the old outflow boundary. Although marginally severe
hail could be noted with the strongest updrafts, gusty winds should
be the primary risk as this maturing MCS spreads across southeast MI
toward the western portions of Lake Erie.
