Many Americans are reaching for their jackets less than a week after a sweltering heat wave pushed temperatures to record highs, as a cold front sweeps across the country
Many Americans are reaching for their jackets less than a week after a sweltering heat wave pushed temperatures to record highs, as a cold front sweeps across the country that's expected to last up to two weeks.
The cooler weather, which will sink temperatures between 5 and 20 degrees lower than July averages, will primarily affect the Upper Midwest, causing thunderstorms from Michigan to Illinois to eastern Missouri on Friday.
Temperatures on Friday will average 75 degrees Fahrenheit in Chicago, 70 degrees in Boston and 86 degrees in Charlotte, N.C. Saturday looks to be a little cooler than Friday.
'The quick change of air mass to cool Canadian air is unusual in that the northwest flow is also going to last a week or two,' said Bill Karins, a meteorologist for NBC News. 'Typically a cool spell in the summer would last one or two days.'
The cool air comes as a relief after a week of excessive warmth that baked every region of the country with several days of record-breaking highs pushing the heat index above 100 degrees.
Last week should be the worst of the summer in terms of heat, according to Boston meteorologist
David Epstein.
Saying that he believes the worst of the heat is over, Epstein explained that severe heatwaves aren't sustainable as the summer wears on due to a number of factors including less daylight and the sun being at a lower angle, 'the likelihood of a weeklong heat wave starts to diminish.'
