Be careful out there. Snow will cause slippery roads and reduced visibilities across much of Minnesota and parts of west-central and southwestern Wisconsin into Friday evening.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern from 6 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 can expect less snow than the southwestern half.

How much snow?

Parts of southwestern Minnesota could see 7 to 11 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 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.
