Winter storm slows Friday travel; temps rebound after cool Saturday

Twin Cities metro area highs are projected to be around 30 on Sunday

Allow extra time to get to your destination through Friday evening. Snow will cause slippery roads and reduced visibilities across much of Minnesota and parts of west-central and southwestern Wisconsin.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern from 10 a.m. Friday to 11 p.m. Friday:

Notice that the Twin Cities metro area rides the eastern edge of the snow, so the northeastern part of the metro area will see lower snow totals than the southwestern half of the metro.

How much snow?

Parts of southwestern Minnesota could see 6 to 10 inches of snow by Friday evening, with lower totals to the east. The area shaded in red has the best odds of 6 or more inches of additional snow:

By Friday evening, it looks like Twin Cities metro area snow totals could range from 1 to 2 inches in eastern Anoka County and northern Washington County to 4 to 5 inches in Carver, Scott, Hennepin and western Dakota counties.

Thursday snow map

Northeastern Minnesota already has plenty of snow cover, but much of southwestern and south-central Minnesota had little or no snow cover on the Thursday report from the Minnesota State Climatology Office:

I imagine that many cross-country skiers, snowboarders and kids with sleds will be out this weekend enjoying the snow that’s falling today.

Saturday highs will be mainly in the teens:

Forecast wind gusts are in knots, with 20 knots equal to 23 mph.

Back to temperatures, Sunday highs are expected to reach the 30s in many areas, with 20s in northeastern Minnesota and western Wisconsin:

Twin Cities metro area highs are projected to be around 30 on Sunday, followed by upper 20s on Monday, which is Martin Luther King Day.

After highs in the lower 30s Tuesday, it turns much colder Wednesday and Thursday, with highs in the single digits. We’ll have a chance of light snow Sunday and Tuesday.
