Cooler Canadian air will bring a taste of fall to the Midwest and Northeast, with lower humidity and crisp nights through midweek.
After a cold front moved through much of the Midwest and Northeast Saturday night into Sunday, cooler air from Canada will settle across the region early this week with high temperatures expected to be 5 to 10 degrees Fahrenheit below the historical average through the Wednesday.
Conditions in Detroit, Pittsburgh and Buffalo, New York, will be more typical of mid-September rather than late August. Cooler, less humid air has already reached parts of the Midwest as northerly winds have developed across the region.
“Dew points, which are a measure of moisture in the air, are expected to drop into the 40s and 50s through Tuesday, making conditions very comfortable by August standards,” AccuWeather Senior Meteorologist Brett Anderson said. “Morning fog may also reduce visibility for some motorists, especially near river valleys, as the ground remains nearly saturated from recent rainfall.”
