An arctic air mass settled over City and much of the country Sunday evening, bringing a deep freeze and the chance of more snow than the city has seen in three years.

A potent shot of Arctic air starts settling in Monday as a massive dip in the jet stream pulls in frigid air across the entire eastern half of the country. Temperatures are set to drop as low as 20 degrees below average Tuesday and Wednesday with highs only reaching the teens, with lows in the single digits and even plunging below zero.

Seasonable, soggy at times this weekend before the coldest weather of the season arrives into the upcoming week.

But it likely will be they worst for people without shelter. There are limited places in metro Detroit to seek shelter. They also, according to the National Coalition for the Homeless, face the real danger of frostbite and even dying from hypothermia.

After days of balmy weather, City is slated to get buried in snow and then hit with an arctic blast expected to unleash a potentially life-threatening chill.
