Washington Post calls it a “Poor man’s polar vortex.”
A cool mass of air will drop from the Arctic regions to Canada and then to the upper Midwest in the coming days, according to the National Weather Service.
With temperatures forecast to be roughly 10 to as much as 30 degrees below average, thermometers across the Midwest could drop into the 50s and 60s instead of the usual 80s and 90s at this time of year.
The unseasonably chilly air may even move into parts of the northern and northeastern United States, including New York and Washington, D.C.
“Remember, this is July!”
“Wednesday morning’s lows may drop into the 40s over a large part of the central U.S.” says the Washington Post. “Remember, this is July!”
“The pattern will probably set some records, especially around the Plains and Great Lakes – where water temperatures are still depressed from the frigid winter in which ice remained on Lake Superior into June.”
In Chicago, overnight lows could reach the low 50s downtown and sink into the low 40s further away from the city on Tuesday and Wednesday, according to Mark Ratzer, a meteorologist with the National Weather Service in Romeoville.
It’s possible the city could reach record lows for July, Ratzer said, though he cautioned the forecast could change before then.
“Temperatures in the far northern Plains into the upper Midwest might even flirt with the low-40s, possibly even into the upper-30s if there will be clear skies,” warns weathercentre.
This will bear “a haunting resemblance to January’s brutally cold weather pattern,” says the Washington Post.
Indeed, several National Weather Service offices are calling this a “polar vortex” event. However, many meteorologists disagree with that terminology.
