Heaviest snow in northern Minn. Sunday night into Monday; a wintry mix, then light rain for the metro area

The latest computer model info still indicates that the heaviest snow Sunday night and early Monday will be over northeastern Minnesota.

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

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of snow or rain.

How much snow?

Drizzle/light rain/snow showers move into the Twin Cities metro area Sunday evening and that mix is expected to change to light rain overnight into early Monday. A light coating of snow is possible, especially in the north metro, but that light coating could disappear by early Monday.

The highest snow totals this Sunday evening into Monday morning will be over north-central and northeastern Minnesota:

NWS Duluth

"Tonight" in the graphic title refers to the overnight hours of Sunday night.

The heavy snow, plus blowing snow and reduced visibilities will make travel difficult in those areas.

Northwestern Minnesota will probably see a combination of snow, sleet and light freezing rain:

Winter storm warnings run from Sunday evening through Monday morning in northeastern Minnesota and parts of north-central Minnesota, plus Douglas county of northwestern Wisconsin:

URGENT - WINTER WEATHER MESSAGE

153 PM CST Sun Jan 6 2019

...A PERIOD OF FREEZING RAIN, MIXED WITH SNOW THIS

EVENING, THEN CHANGING TO A MIXTURE OF RAIN AND SNOW LATE...

.A Winter Weather Advisory has been expanded further to the west

and south for later this evening, through Monday morning. The

areas now in effect include cities north of a line from Morris,

St. Cloud, and Cambridge in Minnesota, and north of Taylor Falls,

Rice Lake and Ladysmith in Wisconsin.

Precipitation will develop this evening in the advisory area. A

period of freezing rain, sleet and snow, will change to rain,

sleet or snow overnight, before ending Monday morning.

Due to the warmer conditions aloft, the precipitation may become

more freezing rain, or rain vs snow overnight, especially in west

central Minnesota where the nose of the warmest air exists. The

area where most of the snow will fall will be in west central

Wisconsin, especially north of east of Ladysmith. Locally two to

four inches will fall in this area. Further to the west, snowfall

amounts will be less than two inches. Due to the freezing rain

possibilities, up to a tenth of an inch of ice may occur before

temperatures warm above the freezing mark. Travel will become

hazardous across these advisory area, especially on untreated

roads.
