MESOSCALE DISCUSSION 2234
NWS STORM PREDICTION CENTER NORMAN OK
0442 AM CST WED NOV 26 2025
AREAS AFFECTED...PARTS OF NORTHERN WI INTO WESTERN UPPER MI
CONCERNING...HEAVY SNOW
VALID 261042Z - 261615Z
SUMMARY...MODERATE TO HEAVY SNOW WILL GRADUALLY SPREAD EASTWARD
THROUGH THE MORNING. BLIZZARD CONDITIONS ARE POSSIBLE.
DISCUSSION...MODERATE TO LOCALLY HEAVY SNOW IS ONGOING AT 10 UTC
ACROSS PARTS OF NORTHERN WI INTO FAR WESTERN UPPER MI, TO THE
WEST/NORTHWEST OF A 993 MB SURFACE LOW NEAR THE NORTHEAST
WI/SOUTHERN UPPER MI BORDER. THIS SURFACE LOW AND THE ACCOMPANYING
MIDLEVEL LOW/TROUGH ARE BOTH FORECAST TO STRENGTHEN AS THEY MOVE
EASTWARD TODAY. AS THIS OCCURS, CONTINUED STRONG ASCENT AND
LOW/MIDLEVEL COOLING WILL ALLOW FOR MODERATE TO LOCALLY HEAVY SNOW
TO GRADUALLY SPREAD EASTWARD ACROSS PARTS OF WESTERN UPPER MI
THROUGH THE MORNING.
SNOW RATES OF NEAR/ABOVE 1 INCH PER HOUR WILL BE POSSIBLE, WITH SOME
POTENTIAL ENHANCEMENT FROM LAKE SUPERIOR AS COOLER TEMPERATURES
ALOFT OVERSPREAD THE REGION. IN ADDITION, STRONG NORTHERLY LOW-LEVEL
FLOW (WITH 40-50 KT CURRENTLY JUST ABOVE THE SURFACE FROM THE KDLH
VWP) WILL ALSO SPREAD EASTWARD WITH TIME. THIS STRONG FLOW COMBINED
WITH INCREASING LOW-LEVEL COLD ADVECTION WILL SUPPORT STRONG GUSTS
TO NEAR/ABOVE 40 MPH, RESULTING IN REDUCED VISIBILITY WITHIN THE
HEAVIER SNOW BANDS AND AT LEAST LOCALIZED BLIZZARD CONDITIONS.
