Air Quality to Improve in Eastern U.S. as Storms Disperse Wildfire Smoke
Wildfire smoke from Canadian wildfires has significantly impacted air quality across the northern U.S. this week, with hazardous levels reported in the Upper Midwest and 'very unhealthy' conditions in the Northeast. However, relief is on the way as severe storms are expected to move into the eastern U.S. this weekend, helping to clear the smoke. Over 125 million Americans in 18 states remain under Air Quality Alerts as of Saturday, but shifting winds and a warm front are expected to bring cleaner air to major cities like Washington, D.C., Baltimore, and Philadelphia. New York City may experience lingering haze until the warm front fully passes. In the Midwest and Great Lakes, a cold front associated with a low-pressure system in Canada is also expected to clear smoke while bringing severe weather to the region. Source time: not specified.
