Probabilistic Heavy Snow and Icing Discussion
NWS Weather Prediction Center College Park MD
321 PM EDT Sat May 09 2020

Valid 00Z Sun May 10 2020 - 00Z Wed May 13 2020

...Upper Midwest...
Day 1...
Low pressure will continue to track across southern Minnesota to
southern Wisconsin near the IL border early Sunday and the near
the MI/OH border region Sunday afternoon.  Low-to-mid level
frontogenesis and strong upper forcing will support bands of
precip north of the low in central to northern WI and northern
lower MI.  The probability forecasts indicate accumulations of 2
inches or more are likely in portions of northern Wisconsin.
Current forecasts indicate a band of an inch or two is expected in
part of northern lower MI.  The event ends as low pressure departs
from the region into the lower Lakes Sunday night.

The probability of significant icing is less than 10 percent.

This is the last scheduled winter weather discussion until around
October 1st.  Other discussions may be issued if other heavy snow
events are forecast between now and then.
