Twin Cities metro area highs are expected to reach the upper 30s on Monday, followed by lower 40s Tuesday and upper 40s on Wednesday. The metro area could touch 50 degrees on Thursday, followed by middle 40s on Friday.

Sunday and Sunday night snow  

Snow is expected to move into west-central and southwestern Minnesota Sunday morning, then spread eastward.

Snow will probably arrive in the Twin Cities metro area and most of eastern Minnesota Sunday afternoon. Periods of snow will continue Sunday night over most of Minnesota, with the snow ending Monday morning

The National Oceanic and Atmospheric Administration's North American Mesoscale forecast model shows the potential snow pattern Sunday through Monday morning:

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.

Here are the snow totals that area generated by the NAM forecast model:

The Twin Cities metro area could see an inch or so of snow by Sunday evening, and then another couple of inches during the overnight hours Sunday night…so between two and three inches are possible by Monday morning in the metro area. We might see a few four inch snow reports in the far southwest corner of the metro.

Higher snow amounts are expected in southwestern Minnesota and parts of west-central and south-central Minnesota.
