Areas affected...Portions of southeastern Lower Michigan

Concerning...Severe Thunderstorm Watch 75...

Valid 302312Z - 310045Z

The severe weather threat for Severe Thunderstorm Watch 75
continues.

SUMMARY...A northeastward-moving MCS will continue to pose a
severe-wind and embedded/brief tornado risk across southeastern
Lower Michigan.

DISCUSSION...A long-lived MCS with an established 70+ kt rear inflow
jet and embedded mesovorticies is tracking northeastward across
southeastern Lower Michigan at around 50 kt. The DTX VWP indicates
40-50 kt of 0-6 km shear oriented perpendicular to the gust front,
which should support continued maintenance of this system. As the
strong cold pool continues tracking into lower 60s F dewpoints,
around 70 mph wind gusts will remain possible. However, locally
stronger gusts up to 80 mph (and a brief tornado) are possible with
any line-embedded mesovorticies and in the vicinity of the
established rear-inflow jet.
