The same cold front that has hit parts of southwestern Pennsylvania with dangerous flash flooding will provide lower humidity for Chicago, Detroit and Minneapolis.
AccuWeather.com Senior Meteorologist Tom Kines said that Chicago and Detroit should be enjoying a less humid day on Thursday after the system moved through Minneapolis on Wednesday.
"It will feel like a breath of fresh air for a lot of folks," he said.
When dew points are in the upper 60s to 70s, people start to feel uncomfortable, Kines said.
Humid air has been the main story in the Northeast for days, so lower dew points behind the cold front will bring some relief.
Dew point temperatures are forecast to drop into the 50s over much of the area, away from the Atlantic Seaboard.
"This is huge news for the eastern part of the country," Kines said.
However, the humid air will return by next week. Minneapolis can expect a rise in the humidity to return by the weekend with Chicago and Detroit following early next week.
