....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM LAKES
HUDSON AND ERIE WEST-SOUTHWESTWARD ACROSS THE MIDWEST...

....SUMMARY...
Strong/locally severe storms will be posible from Lakes Huron and
Erie southwesteward into the Midwest Friday.

....Synopsis...
An upper trough will continue moving slowly eastward out of the
north-central U.S. across the Great Lakes and Midwest on Friday,
though the more vigorous portion of the trough is forecast to eject
northeastward across Ontario into the Hudson Bay region.

At the surface, a cold front is forecast to continue eastward across
the Great Lakes region, southeastward across the Midwest, and
southward across the Plains.  By the end of the period, the front
should extend from the Lower Great Lakes west-southwestward across
the Ohio Valley, and into Oklahoma and northern Texas.

....Lower Michigan/northern Ohio/northwestern Pennsylvania across the
Midwest...
Afternoon destabilization across the Midwest ahead of the advancing
cold front will support development of scattered thunderstorms.
While stronger flow aloft will remain to the cool side of the front,
moderate low- to mid-level westerlies extending south into the
Midwest states should allow a few stronger storms to evolve,
including a few small clusters/line segments.  The strongest storms
will pose some risk for marginal hail and wind gusts capable of
mainly tree damage, into the evening hours before a nocturnal
convective decrease commences.
