Areas affected...Central Great Lakes

Concerning...Severe Thunderstorm Watch 402...

Valid 092242Z - 100015Z

The severe weather threat for Severe Thunderstorm Watch 402
continues.

SUMMARY...Marginally severe hail and wind remain possible for the
next few hours.

DISCUSSION...Deep cyclonic flow is decidedly westerly across much of
lower MI early this evening. Scattered thunderstorms have developed
in response to the cyclone, and are spreading east across eastern
portions of ww0402. However, diagnostic data exhibits poor buoyancy,
and MLCAPE is generally less than 500 J/kg ahead of this activity.
Most updrafts are struggling to maintain intensity, though
marginally severe hail might be noted within the strongest updrafts
at times. Current thinking is locally strong, to perhaps marginally
severe, thunderstorms will propagate across the remainder of ww0402
over the next few hours, and gradually weaken as they approach the
western shores of Lake Huron/Erie.
