MESOSCALE DISCUSSION 2278
NWS STORM PREDICTION CENTER NORMAN OK
0952 AM CST SUN DEC 28 2025
AREAS AFFECTED...NORTH CENTRAL IOWA...SOUTHERN AND EASTERN MINNESOTA
AND NORTHWESTERN WISCONSIN
CONCERNING...HEAVY SNOW
VALID 281552Z - 282145Z
SUMMARY...HEAVY SNOW, WITH RATES NEAR 1 INCH PER HOUR, IS EXPECTED
TO DEVELOP BY MIDDAY IN EAST CENTRAL MINNESOTA AND NORTHWEST
WISCONSIN. OCCASIONAL BLIZZARD CONDITIONS ARE EXPECTED INTO
SOUTHERN MINNESOTA AND NORTHERN IOWA.
DISCUSSION...GRADUAL EROSION OF A WARM NOSE (NOTED IN THE 12Z MPX
SOUNDING) WILL CONTINUE THROUGH THE AFTERNOON FROM EASTERN MN INTO
NORTHWEST WI AS A RESULT OF STRENGTHENING ASCENT AND
COOLING/SATURATION OF PROFILES TO THE NORTHWEST OF A DEEPENING
CYCLONE NOW NEAR THE IA/MO/IL BORDER. NEAR-SURFACE COOLING FROM
NORTHWEST-TO-SOUTHEAST WILL BECOME MORE FAVORABLE FOR
ACCUMULATING/HEAVY SNOW FROM EAST CENTRAL MN INTO NORTHWEST WI
WITHIN THE PRIMARY DEFORMATION BAND, WHILE SNOWFALL RATES WILL BE
LOWER FARTHER SOUTHWEST INTO SOUTHERN MN/NORTHERN IA. HOWEVER, A
STRENGTHENING PRESSURE GRADIENT AND RAPIDLY FALLING TEMPERATURES
INTO THE TEENS/SINGLE DIGITS WILL RESULT IN BLOWING SNOW AND
BLIZZARD CONDITIONS (FREQUENT GUSTS 35-50 MPH WITH VISIBILITY
REDUCED TO 1/4 MI OR LESS) FROM SOUTHERN MN/NORTHERN IA THROUGH THE
AFTERNOON.
