CHICAGO — An arctic air mass that brought snow and ice to an area stretching from the Rocky Mountains to northern New England on Monday was poised to give way to record-breaking cold temperatures today.

In Chicago, where as much as 6 inches of snow fell, an Envoy Air flight from Greensboro, North Carolina, slid off an icy runway at O’Hare International Airport as it tried to land at about 7:45 a.m. None of the 38 passengers and three crew members were injured, according to the city’s aviation department. And in Kansas, the highway patrol reported that a truck driving on the highway lost control on an icy road and slammed head-on into another truck, killing a juvenile in the other vehicle.

Snowfall totals could reach up to a foot or more in some areas of Indiana, Michigan and Vermont, according to the National Weather Service.

A strong arctic cold front was expected cross West Virginia, bringing a dramatic drop in temperatures, along with winter weather and wind chill advisories from the National Weather Service in Charleston.

On Monday temperatures in the Huntington and Charleston region reached the mid-60s, but rain was predicted to switch to snow overnight and continue into part of Tuesday.

“Generally 1 to 2 inches can be expected, with amounts to 4 inches in the mountains,” the National Weather Service forecast said on Monday evening. “Roads may become slick by Tuesday morning, making for a treacherous commute.”

A wind chill advisory has also been issued for the region. As a result, Harmony House on 4th Avenue in Huntington made plans to be open at 6 a.m. Tuesday for those who are unsheltered.

“Very cold wind chills expected,” the advisory said. “Wind chills as low as 15 below zero.”

The winter weather advisory remains in effect from 1 a.m. to 7 p.m. Tuesday and the wind chill advisory remains in effect from 7 p.m. Tuesday to 8 a.m. Wednesday.

Forecasters also said if Huntington and Charleston receive an inch of snow Tuesday it would be the earliest inch of snow since November 2013.

Other places in the path of Monday’s air mass saw ice and rain. Denver saw just a few inches of snow but suffered numerous accidents on icy roadways because the snow fell during the morning commute.

More than 950 flights were canceled at Chicago’s airports and officials in the area opened warming centers. In Michigan, some schools closed early, as did dozens of schools in the St. Louis area.

The snow and ice was just the first punch from a weather system that pushed frigid air from Siberia across an area stretching from the Rocky Mountains to the East Coast. Temperatures below freezing were forecast as far south as Texas’ Gulf Coast.

“This is an air mass that’s more typical for the middle of January than mid-November,” said National Weather Service meteorologist Kevin Birk. “It is pretty much about the coldest we can be this time of year (and) it could break records all over the region.”

According to Birk, the lows on Tuesday could drop into the single digits or low teens in Illinois, Wisconsin and Iowa, with highs climbing no further than the low 20s. The forecast high of 21 degrees for Chicago would be a full seven degrees lower than the previous record set for Nov. 12.

In some areas, temperatures plunged quickly. Temperatures in Denver climbed past 70 degrees over the weekend only to fall to 14 degrees early Monday.

One area where the low temperatures was particularly concerning was in central Wyoming, where officials were searching for a 16-year-old autistic boy who went missing wearing only his pajamas on Sunday, prompting a search that included certified human trackers, helicopters, dogs, and planes.

The National Weather Service said areas west of the Rocky Mountains would be spared the arctic air, with above average temperatures expected in some of those places.
