Sunday snow; cold and windy Monday

Snow lovers will be smiling Sunday afternoon.

A low pressure system is expected to spread snow across Minnesota Sunday into Sunday evening.

Here’s the Saturday evening run of the National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model, showing simulated radar for Sunday and Sunday evening:

The snow could begin early Sunday morning in northwestern Minnesota, then spread to the east and south.

This model shows accumulating snow holding off until Sunday afternoon in the Twin Cities metro area and southeastern Minnesota.

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.

The highest snow totals, in the two to three inch range, are expected to be over eastern Minnesota and western Wisconsin:

NWS Twin Cities

The higher terrain along the north shore of Lake Superior, combined with enhanced moisture due to winds off of the lake, could lead to some three to five inch snow totals in Cook county of northeastern Minnesota.

The National Weather Service has issued a winter weather advisory from 10 a.m. to midnight on Sunday for that section of the north shore:

Here are details of the advisory:
