Thick Smoke from Major Canadian Wildfires Blankets Great Lakes, Mid-Atlantic, and Northeast US

Major Canadian wildfires are causing thick smoke to blanket the Great Lakes, Mid-Atlantic, and Northeast U.S. Visibility has significantly degraded in many areas, with Washington D.C. experiencing 2-mile visibility and Michigan around 1-mile visibility. While much of the thickest smoke remains aloft, it is mixing down to the surface. Showers and storms in Michigan are expected to help cleanse the atmosphere. Smoke is expected to continue impacting air quality through the weekend to varying degrees across these regions.
