The birth of a storm
Here is a very busy graphic from the Chanhassen NWS office. Previously I posted a graphical forecast from Duluth.
Here's the deal. A major winter storm will hammer a large part of Minnesota, Wisconsin and Upper Michigan later tonight and all day Saturday.
We expect clouds to gather snowflakes this afternoon in the Dakotas. Snow will increase in coverage and intenity later this afternoon in western Minnesota. Snow begins in the Twin Cities after the rush hour. Heavy snow falls overnight and begins to taper in the west.

As the storm system strengthens tonight and Saturday morning winds will howl and temperatures will plummet. We should find ourselves in very difficult to perhaps nearly impossible travel on Saturday in a large part of Minnesota and western Wisconsin.
Pay heed to local authorities on travel advice on Saturday. Total snowfall accumulations on the average of six to twelve inches are likely from Willmar to the Twin Cities to Hayward.
Lake enhanced snowfall of greater than sixteen inches will be possible in Ashland and Superior.
Strong northwest winds will make it extremely challenging to measure the snow. Expect drifts several feet high by Saturday afternoon. Visibilities will be at or below a quarter mile at times.
