MD 0331 CONCERNING FREEZING RAIN FOR CENTRAL AND NORTHEAST WISCONSIN


Mesoscale Discussion 0331

0727 AM CDT Thu Apr 02 2026

Areas affected...central and northeast Wisconsin

Concerning...Freezing rain 

Valid 021227Z - 021530Z

SUMMARY...Freezing rain will continue this morning across portions
of central and northeast Wisconsin.

DISCUSSION...Moderate to heavy freezing rain continues across
central and northeast Wisconsin this morning. Several ASOS/AWOS
sites have measured around 0.25" of ice accretion in the past 6
hours with 1 hour totals up to 0.1". Strengthening low-level
east-northeasterly flow should maintain below freezing surface
temperatures across this region this morning. Given the upstream
radar mosaic, expect similar ice accretion rates for at least a few
more hours, especially across northeast Wisconsin where temperatures
remain in the upper 20s and the heaviest precipitation should last
longer.
