NWS STORM PREDICTION CENTER NORMAN OK
0532 PM CST TUE NOV 25 2025
AREAS AFFECTED...CENTRAL MINNESOTA INTO NORTHERN WISCONSIN
CONCERNING...HEAVY SNOW
VALID 252332Z - 260530Z
SUMMARY...HEAVY SNOWFALL WITH RATES UPWARDS OF 1-2 INCHES/HOUR WILL
SPREAD EAST/NORTHEAST ACROSS CENTRAL MINNESOTA INTO NORTHERN
WISCONSIN THROUGH THE EVENING HOURS. ADDITIONALLY, STRONG WINDS WILL
CONTINUE TO SUPPORT AREAS OF BLIZZARD CONDITIONS, ESPECIALLY IN OPEN
COUNTRY AND UNDER HEAVIER SNOW BANDS.
DISCUSSION...LATEST RADAR MOSAICS AND SURFACE OBSERVATIONS SHOW AN
INTENSE CYCLONE OVER THE TWIN CITIES AREA. ALOFT, ASCENT ASSOCIATED
WITH A NARROW, BUT STRONG, ZONE OF WARM ADVECTION BETWEEN 850-700 MB
IS OVERLAPPING WITH LIFT WITHIN THE LEFT-EXIT REGION OF A 500 MB
JET, WHICH IS SUPPORTING A BROAD SWATH OF MODERATE TO HEAVY SNOWFALL
RATES FROM THE SISSETON HILLS IN NORTHEAST SD INTO WEST-CENTRAL MN.
THESE ASCENT MECHANISMS WILL CONTINUE TO BE FAVORABLY PHASED OVER
THE NEXT SEVERAL HOURS, AND WILL SUPPORT 1-2 INCH/HOUR SNOWFALL
RATES ACROSS CENTRAL MN TO NORTHERN WI AND PARTS OF THE UPPER
PENINSULA AS THE CYCLONE AND SURFACE FREEZING LINE SHIFT EAST. GIVEN
THE FOCUSED CORRIDOR OF MESOSCALE ASCENT, SNOW BANDING WILL BE
POSSIBLE AND MAY SUPPORT LOCALLY HIGHER SNOWFALL RATES IN EXCESS OF
2 INCHES/HOUR.
IN ADDITION TO THE POTENTIAL FOR HEAVY SNOWFALL RATES, 25-35 MPH
SURFACE WINDS ON THE BACKSIDE OF THE SURFACE LOW ARE SUPPORTING
AREAS OF BLIZZARD CONDITIONS WITH VISIBILITY BELOW 1/4 MILE RECENTLY
NOTED ON SEVERAL WEB CAMS ACROSS WESTERN MN. ALTHOUGH TEMPERATURES
WILL REMAIN RELATIVELY WARM (30-32 F), THE COMBINATION OF STRONG
WINDS AND MODERATE/HEAVY SNOWFALL RATES WILL CONTINUE TO PROMOTE
AREAS OF BLIZZARD CONDITIONS, ESPECIALLY ACROSS OPEN COUNTRY AND
UNDER ANY HEAVIER SNOW BANDS THAT DEVELOP.
