A cool mass of air heads toward the United States from the upper regions of Canada and Alaska this week according to the National Weather Service.
According to the NWS a mass of cold air will drop from the Arctic regions to Canada and then the upper Midwest next week.
Temperatures across the Midwest will drop into the 60s and 70s-a sharp difference from the 80 degree and 90 degree temperatures from recent weeks. And the relatively cooler air may be felt as far East as New York and Washington
The cool breezes may be a welcome relief this time around but remember the last few times we got hit with Arctic air？
Temperatures in cities including Chicago Cleveland New York and Louisville fell into single-digit and negative territory for long stretches during the harsh winter months of early 2014. But we’re sure you remember
According to the National Weather Service____A. the cool mass of air originates from Canada
B. a mass of cold air will affect both Canada and the U.S
C. the chilly weather is back to the globe
D. only the upper Midwest will be affected by the cool air
