Major winter storm expected to hit much of US before Christmas

Heavy snow, powerful winds, and bitterly cold temperatures will potentially snarl holiday travel

A massive winter storm system is expected to strike much of the US days before Christmas, potentially snarling holiday travel as motorists and air travelers contend with heavy snow, powerful winds, and bitterly cold temperatures across several regions.

This sprawling storm system coincides with the arrival of an Arctic air mass that will consume much of the country “this upcoming week”, according to the National Weather Service. Between Tuesday and Saturday, temperature highs are expected to average from 10 to 35F below normal from the north-west to the eastern two-thirds of the US.
