Wintry mix Sunday evening into early Monday; heavy snow in northern Minnesota

Parts of northern Minnesota will see heavy snow Sunday evening into Monday, while a wintry mix of light rain/light freezing rain, sleet and light snow moves across central and southern Minnesota.

The wintry mix is expected to bring an icy glaze to untreated roads, streets and sidewalks.

The big picture

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern from Sunday evening through Monday afternoon:

…FREEZING DRIZZLE EARLY THIS EVENING…
…FREEZING RAIN LIKELY AFTER MIDNIGHT…

.A Winter Weather Advisory has been expanded further to the west
and north across central Minnesota due to more freezing
precipitation expected vs, snow for later this evening, through
Monday morning. Also Freeborn County was added to this advisory
due more ice accumulation. Chippewa County in Wisconsin has been
cancelled due to much warmer conditions expected overnight,
limiting the potential of freezing precipitation.

Conditions will slowly deteriorate overnight as light precipitation
begins to develop across Iowa, and expand northward across
southern, and central Minnesota, as well as west central
Wisconsin. Initially, temperatures will hold, or remain nearly
steady above freezing across portions of south central, east
central Minnesota, and west central Wisconsin through midnight.
Once winds become more west or northwest overnight, temperatures
will begin to drop below freezing. Thus, freezing precipitation is
expected. Further to the west and north, temperatures will remain
below freezing leading to icy conditions developing faster.

Road conditions…based on the latest road sensors from the
Minnesota Department of Transportation, indicated above freezing
sensors from south central to east central Minnesota, as well as
west central Wisconsin.
