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.
The smoke is forecast to reach cities like Seattle; Helena, Montana, and Grand Forks, North Dakota.
The Northeast and Midwest won’t escape the week without smoke clouding the sky, either.
“Later this week, there is some smoke risk as well as the potential for poor air quality to return as a surface high slides into the Upper Midwest, bringing a northern wind into the region and in the Northeast,” said Joseph Bauer, AccuWeather Meteorologist.
“The general pattern through at least the middle portion of the month is supportive of having more episodes of smoke enter the Midwest and Northeast from Canada,” said Bauer. “As a result, more occurrences of poor air quality and hazy skies can occur in these areas more frequently.”
AccuWeather meteorologists are currently monitoring if the Northeast and Midwest will endure the same level of smoke that they did the previous week.
Over 500 active fires were burning across Canada as of Monday, according to the Canadian Interagency Forest Fire Centre (CIFFC). By Monday morning, the total acreage burned this year was over 20.7 million. For context, the state of South Carolina is approximately 20.5 million acres. The previous record was set in 1995 when wildfires burned more than 17.5 million acres across the nation.
Of the fires active on Monday, at least 284 were considered to be “out of control.” Since the start of the year, there have been 3,229 across Canada, according to the CIFFC, most of which started due to natural causes such as lightning strikes.
