While the first of two clipper storms this week will stay weak until swinging east of New England, the second clipper storm rolling in this weekend will strengthen significantly.
People on weekend ski trips or partaking in other travel from the Great Lakes to New England will run the risk of getting stuck in the storm and the frigid air moving in.
According to AccuWeather.com Senior Meteorologist Henry Margusity, "The storm could bring life-threatening conditions, especially in New England with very low temperatures and strong winds combining with snow to bring blizzard conditions."
Initially, light snow will move across the Midwest Friday night into Saturday. However, winds will increase after the snow begins as bitterly cold arctic air arrives and AccuWeather RealFeel® Temperatures plunge below zero F.

Even where a small amount of snow falls, there will be extensive blowing and drifting of the snow on the ground as the storm progresses and in its wake.
Roads may get snow covered and very slippery in some areas. The frigid air moving in will render most inexpensive ice-melting compounds ineffective. Areas of slush and standing water will freeze.

Whiteout conditions are possible in parts of northern Indiana, Michigan, southwestern Ontario and upstate New York.
Some lake-effect snow will also occur off Lake Erie even though this shallow water body is mostly frozen over.
