A northerly to northwesterly flow that ushered in rounds of smoke during the workweek is easing up this weekend, leading to an improvement in air quality readings for the coming week in the northern part of Georgia after several days of hazy conditions caused by wildfires in Canada.

Dozens of wildfires burning in southern Canada produced smoke that traveled over the Great Lakes and Northeast during the workweek.

The unhealthy air caused health advisories to be issued for many communities and more than 120 million Americans were put under Air Quality Alerts on Thursday, and unhealthy levels of air quality lingered across much of the inland Northeast, Great Lakes, and mid-Atlantic states early Friday morning.
