Areas affected...Parts of eastern WI and Upper MI

Concerning...Heavy snow

Valid 160925Z - 161430Z

SUMMARY...A swath of heavy snow with rates around 1 inch per hour
are expected through the morning hours.

DISCUSSION...Mosaic radar and satellite imagery show an increasingly
defined deformation zone and inferred strong ascent evolving in a
north-south corridor extending from parts of Upper MI across eastern
WI. Here, the GRB 06Z sounding sampled a cold and deeply saturated
profile, which combined with the strong ascent, will promote heavy
snowfall rates of 1 to locally 2 inches per hour through the morning
hours. Additionally, strong surface winds may lead to areas of
blowing snow and reduced visibility.
