Arctic air mass ushering in below-zero wind chills this week

A man is bundled up against the cold in downtown Chicago, Sunday, Jan. 27, 2019. More than with many snowstorms Chicagoans have endured in recent history, where you live will greatly impact how much snow you arise to Monday morning, forecasters said.

It’s going to be cold Monday morning, and the afternoon’s brief reprieve of above-freezing temperatures will give way to frigid Arctic air set to hang around for several days, local meteorologists said Sunday.

“We’re going to have a pretty good little bit of warming through Monday with highs right around 38 degrees,” said John Darnley, of the National Weather Service in Moon Township. “Then we just go downhill from there.”

Tuesday will see its high temperature, about 38 degrees, at around midnight, Darnley said, “and from there, it just nose dives.”

He said the temperature will drop about 5 degrees every six hours all the way through Thursday morning, when the low will be about minus 5 degrees.

The feels-like temperature at that point will be around minus 22 degrees, he said.

Wednesday could be a record-breaking day in terms of the lowest high temperature. The record for Jan. 30 was set in 1977 at 10 degrees. The high temperature Wednesday, according to the NWS forecast, will be about 7 degrees.

The system ushering in the Arctic air mass could result in some snow Tuesday or Wednesday, “but don’t let anyone tell you it’ll be 4-6 inches,” Darnley said.

At most, he said, accumulation could total 2 inches.
