UPDATE: Winter Storm Watch Upgraded to Warning

A major winter storm is moving in on the Twin Cities region — just in time for the afternoon rush hour. 

At noon, the National Weather Service in Chanhassen bumped a "Winter Storm Watch" up to a "Warning" in anticipation of storm that will sweep across central Minnesota and western Wisconsin. The storm will be preceded by a blast of warm air, bringing with it a "mixed bag" of precipitation that runs the gamut between rain, snow and ice.

Snow forecasts are similarly variable. Across the region, estimates range from eight to 14 inches of snow in central Minnesota and northwest Wisconsin to almost nothing in southern Minnesota. The Twin Cities and neighboring cities will likely see one to four inches, with heavier snowfall possible in the northern suburbs.

The most severe weather will likely occur Tuesday night through Wednesday morning, with the most intense precipitation and gusty winds rolling in as the storm tracks east. These conditions could greatly reduce visibility on roads and highways around the Twin Cities region.

The Minnesota State Patrol issued the folowing advice to motorists:

• Buckle up, of course, and drive slow. Leave ample time for delays when traveling.

• Layer a bulky winter coat or blankets over a child's safety harness to ensure that the restraints fit properly.

• Don't tailgate. Leave more stopping distance between your vehicle and others than you normally would. Keep even more distance between your car and snowplows — at least five car lengths.

• If you go into a skid, take your foot off the gas and steer in the direction you want the nose of your vehicle to go. 

• Apply steady, firm pressure when braking. No sudden stops. Don't pump the brakes.
