Mesoscale Discussion 2204
NWS Storm Prediction Center Norman OK
0847 AM CST Mon Nov 10 2025

Areas affected...northeast IL...northwest IN...and western Lower MI

Concerning...Heavy snow 

Valid 101447Z - 101945Z

SUMMARY...Brief periods of moderate to heavy lake effect snow may
impact southeastern Lake Michigan vicinity through the day as the
snow back shift east/southeast.

DISCUSSION...A band of lake effect snow is oriented from western
Lower MI to northeast IL this morning. This band is expected to
pivot east/southeast over time as low-level winds shift to
northwesterly with time and eastward extent. Areas along the
southeastern shore of Lake Michigan will see periods of moderate to
heavy snow as the band progresses east/southeast through the day. A
lack of stronger frontogenesis should temper overall snowfall rates,
but brief periods of near 1 inch per hour rates will be possible.
