Less than a week after the last round of Canadian wildfire smoke blotted out the skies of the Midwest and Northeast, prompting numerous air quality alerts, more ground-level smoke will return to the United States. However, this time it may cover a broader scope across the northern states.
Air quality levels in the Northeast and Midwest had improved drastically by Monday following the latest incursion of wildfire smoke, thanks to thunderstorms across the regions that flushed the particles from the air. “The smoke is forecast to shift out of the Canadian Rockies and Prairies into the neighboring northern Plains and Northwest U.S. through at least Tuesday, leading to poor air quality and low visibility,” said AccuWeather forecasters.
