A storm system producing blizzard conditions on the Front Range will create a mess on the roadways in the Upper Midwest and Great Lakes. Ice and snow is ahead through Wednesday. Winter weather alerts are in effect from the mountains in the West to the Great Lakes. Up to a .10" of an inch of ice is possible in some areas. In the colder air, 6" to 12" of snow may accumulate. The low pressure center will push from the Front Range to the Great Lakes over the next 24 hours. Bands of heavy snow will fall further to the north, with a mix of freezing rain, sleet, and snow for locations to the south. As the system moves east by Wednesday, the wintry mixed precipitation will come to an end in the Plains but snow will continue for the Great Lakes. For WeatherNation: Meteorologist Mace Michaels
