Mesoscale Discussion 0244
NWS Storm Prediction Center Norman OK
1217 PM CDT Wed Mar 19 2025

Areas affected...Central WI...southern MI Upper Peninsula

Concerning...Heavy snow=20

Valid 191717Z - 192015Z

SUMMARY...Heavy snow, with rates of 1 to 2 inches per hour, will
continue and expand northeast across the discussion area this
afternoon.

DISCUSSION...Upper-level low pressure over northeast KS will
continue moving steadily east as an accompanying surface low moves
from northern MO into northern IL by late afternoon. As surface
temperatures cool, snow will expand in coverage in response to
increasing large-scale ascent and spread northeast through late
afternoon. Intensifying frontogenetic forcing within the 850-700 mb
layer will contribute to snowfall rates of one inch per hour
becoming widespread, and weak elevated buoyancy/embedded convective
elements will result in areas of locally higher rates of up to 2
inches per hour.

As the surface low moves east-northeast, strong/gusty north to
northeast winds of 30 to 45 mph with higher gusts will result in
areas of whiteout conditions.
