"Paul, where should I turn: local TV meteorologists, computer models, or plowing companies, who seem to have some of the best information?" All of the above.
Take all the snowfall predictions and divide by 2. That will be closer to reality.
Beware of models; they're only as good as the physics involved, and the quality of weather data feeding these simulations. The art is knowing which model to believe, and when. I've discovered (the hard way) that it's better to be conservative with snowfall predictions. Because Mother Nature always finds a new and creative way to trip you up.
Travel won't be a problem today; a surge of snow pushes in from the south late tonight. Rush hour tomorrow may be anything but with some 2-5 inch amounts possible (over 6" parts of southern MN).
As I've mentioned in the past - the air temperature during a storm is as important as "how many inches?" I expect 20-25 F tomorrow, a colder snow. Wheel tracking glazing, from traffic compacting snow, may result in glaze ice, especially Friday AM.
The storm next Tuesday doesn't look quite as impressive; a couple inches of slushier snow?
This may be one of the best weekends of winter to get out and PLAY in that snow!
- 67 percent of U.S. counties and 43 states were affected by “billion-dollar damage” extreme weather events in 2011 and 2012.
- 1,107 fatalities resulted from these 25 extreme weather events in 2011 and 2012.
- Up to $188 billion in damage was caused by these severe weather events in 2011 and 2012.
- $50,346.58 was the average household income in counties declared a disaster due to these weather events—3 percent below the U.S. median household income of $51,914. 
- 356 all-time high temperature records were broken in 2012.
- 34,008 daily high temperature records were set or tied throughout 2012, compared to just 6,664 daily record lows—a ratio of 5-to-1.
- 19 states had their warmest year ever in 2012.
