Smoky Conditions Persist Across Large Parts of U.S.
At least 10 states from the Midwest to the Northeast on Friday will again face smoky conditions created by raging wildfires in Canada, capping a week in which millions of people struggled to cope with poor air quality.
Smoke that has obscured skylines and made it difficult for some to breathe was expected to linger into the long Fourth of July weekend, according to the National Weather Service. However, the air quality was expected to slowly improve as thunderstorms help disperse the smoke and possibly clear the way for Independence Day firework celebrations.
