Wildfire Smoke Chokes Midwest And Northeast, Relief Expected For Fourth Of July

A change in wind direction across different layers of the atmosphere will be responsible for the relief from the dangerously smoky air, but experts caution that the return of an air mass with higher humidity and thunderstorms will replace one hazard with several others.ACCUWEATHER

“Poor air quality as a result of smoke from the record-setting wildfires in Canada has been plaguing portions of the Midwest and Northeast this week,” said AccuWeather forecasters, but some relief is expected ahead over the early parts of the Fourth of July holiday week,” said AccuWeather. 

As of Thursday morning, air quality alerts from the National Weather Service were in effect across more than a dozen states from Minnesota to Rhode Island. “Pollution from the smoke was in the ‘unhealthy’ to ‘very unhealthy’ range in cities such as Chicago. Detroit and Pittsburg,” said Plume Labs, an AccuWeather-owned air quality company.
