MD 0347 CONCERNING FREEZING RAIN FOR NORTHERN WISCONSIN AND THE FAR WESTERN UPPER PENINSULA OF MICHIGAN.
Mesoscale Discussion 0347
NWS Storm Prediction Center Norman OK
0928 PM CDT Tue Mar 29 2022
Areas affected...Northern Wisconsin and the far western Upper
Peninsula of Michigan.
Concerning...Freezing rain
Valid 300228Z - 300630Z
SUMMARY...Expect freezing rain, and possibly thunderstorms, to
develop in the next 1 to 2 hours.
DISCUSSION...A broad region of warm air advection showers and
thunderstorms is lifting north through Wisconsin. Currently,
temperatures are mostly at or above freezing where convection has
occurred, but dewpoints are quite dry which should yield some
evaporative cooling and cause temperatures to drop below freezing.
Forecast soundings show a thermal profile favorable for freezing
rain and potentially thunderstorms continuing into the overnight
period. The best chance for greater freezing rain accumulation will
likely be across northern Wisconsin where temperatures are already
below freezing with dewpoints in the 5 to 15F range. This should
lead to temperatures dropping into the mid to upper 20s once
precipitation begins. These temperatures, combined with moderate
surface winds should create an environment favorable for ice
accretion. Locally higher ice accumulation is likely in any areas of
thunderstorms.
