Snow update for Saturday/Saturday night; who will see the most snow

Sunday looks quiet

Kids with sleds or snowboards will be happy with this forecast of fresh snow. People who are out driving in it will be dealing with slippery roads and reduced visibilities.

Snow timing

Snow has already moved into southwestern Minnesota and parts of south-central Minnesota this Saturday morning. The snow is expected to spread to the east and north this afternoon. A separate area of snow has begun in northeastern Minnesota.

The snow lingers through this evening in most areas, then it tapers off from west to east later tonight. Snow may linger a little past daybreak on Sunday in parts of northeastern Minnesota and far southeastern Minnesota plus western Wisconsin.

The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential precipitation pattern from noon today through noon on Sunday:
