Smoke from wildfires over Canada's Northwest Territories has been drifting thousands of miles to the southeast and high over head in the north-central and northeastern portions of the United States.
According to AccuWeather Senior Meteorologist Brett Anderson, "Through the weekend, the sky may appear to be overcast at times from high-flying clouds and at other times it may be barely noticeable."
The smoke, cruising along at 25,000 feet, is being carried along by strong upper level winds, known as the jet stream. The dip in the jet stream is forecast to continue into Sunday over the mid-Atlantic and Northeast U.S.

The smoke is originating too far away and occurring too high in the atmosphere to significantly affect air quality and should not be a problem for people with respiratory problems.
In fact, much of the air quality from the Great Lakes to the Northeast will be good through this weekend, due to lower-than-average humidity levels for the middle of August.
The particulates are scattering light and at certain times of the day the landscape may seem to have a yellowish tint. Near sunrise and sunset, the sky may have more orange and red hues, compared to usual. The smoke can also affect the appearance of this month's Supermoon.
