As wildfire smoke worsens air quality this weekend, here's what to expect and when

More than 100 million Americans are currently under air quality alerts due to wildfire smoke originating from Canada and northern Minnesota. This smoke releases microscopic particles into the atmosphere, creating serious health risks for the population. Shifting wind patterns have pushed a thick haze into major metro areas throughout the Mid-Atlantic, Northeast, and Great Lakes regions. Residents are advised to monitor air quality as conditions worsen over the weekend across these affected areas.
