....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
MINNESOTA...WISCONSIN AND MICHIGAN...

....SUMMARY...
Isolated strong to severe thunderstorms capable of producing
damaging gusts and hail are possible across parts of Minnesota,
Wisconsin and Michigan on Wednesday.

....Upper Midwest/Great Lakes...

Moderate northwesterly mid/upper level flow will overspread the
region as a shortwave trough migrates east/southeast across Ontario
and Quebec on Wednesday. A surface low will shift east across
Ontario during the afternoon, with a trailing cold front developing
southeast across the Upper Midwest. Ahead of the front, a corridor
of mid/upper 60s F surface dewpoints will reside across parts of
southern MN, WI, and the Upper Peninsula of MI. This will aid in a
corridor of moderate instability ahead of the front. Frontal
convergence will be weak, with southwesterly low-level winds
forecast across the warm sector. Stronger large-scale ascent also
will remain focused north of the international border. Nevertheless,
sufficient vertical shear and instability should support at least
isolated strong to severe storms capable of damaging gusts and
perhaps a few instances of hail.
