Plumes of dense smoke from uncontained wildfires in Manitoba, Canada, will blow across more than a dozen central and eastern states Friday and Saturday.

A milky haze overtook Midwestern skies Friday, with the smoke low enough in the atmosphere to reduce air quality from Minnesota to Michigan. The smoke could push southward to Illinois and Indiana this weekend.
