…MIXED PRECIPITATION INCLUDING FREEZING RAIN LIKELY OVERNIGHT
THROUGH MUCH OF SATURDAY…
.A storm system moves through the area late tonight through much of
Saturday. Initial impacts expected to reach counties in Northeast
Iowa early in the overnight hours, move into southeast Minnesota
shortly thereafter, followed by far southwest Wisconsin. As the
initial mix of snow, sleet, and freezing rain shifts northeast
through the early morning hours, the probability for freezing rain
increases. Current confidence suggests freezing rain onset near 3AM
lasting into the afternoon. Hourly ice accumulations above 0.02"
expected at the height through most of the morning hours.
Above freezing temperatures slowly build from south to north through
the afternoon and early evening, decreasing overall freezing
concerns. Highest overall ice accumulations near 0.2" are expected
in northeast Iowa and 0.05"-0.15" possible elsewhere from far
southwest Wisconsin through southeast Minnesota.
Freezing precipitation can quickly cause hazardous road conditions.
Higher ice amounts can also result in fallen trees and power lines
resulting in power outages.

to one inch and ice accumulations up to two tenths of an inch.
