Mesoscale Discussion 0264
NWS Storm Prediction Center Norman OK
0425 AM CDT Mon Mar 16 2026
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.
