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.
