Cool air to visit parts of U.S.

Put away those shorts and tank tops, Chicago, and get ready for another “polar vortex.”

That’s what some people are calling the unseasonably cool temperatures expected to come to the northern and eastern United States next week, as a patch of cold air flows from northern Canada to the Great Lakes area.

The temperature in some areas will slide as low as 15 to 20 degrees below normal and some states are likely to see cold rain and thunderstorms.

The upper Midwest could see some of the coldest weather, with highs in the low- to mid-60s. Parts of the Chicago area could see lows overnight dip into the 40s.

The cool air isn’t expected to be anything like the polar vortex of this January, which brought record-breaking subzero temperatures.

“I wouldn’t call it a polar vortex,” Mike Gillispie, a meteorologist for the National Weather Service in Sioux Falls, S.D., said of the latest temperature shift.

“It’s going to be a shot of some colder air, but it’s not going to hang around for more than a few days.”
