Smoke from wildfires in Alberta is still detectable across most of the Eastern United States today, but the Canadian government’s smoke forecast expects a significant decrease throughout the lower 48 states on Monday.
Cooler weather along with a slight chance of showers off and on in Alberta over the last several days has slowed the progress of the wildfires, including the 230,000-hectare (568,000-acre) Chuckegg Creek Fire at the town of High Level. Those conditions are expected to continue during this week, so it appears that U.S. residents will get a respite from polluted air that at times has been very unpleasant in the Northwest, especially along the Canadian border in Montana and Idaho.
The map above represents conditions today, Sunday June 2. The map below is the Canadian government’s forecast for smoke tomorrow, June 3. The Canadian system does not predict smoke conditions in the south half of the U.S. (outside of the box with the black lines).
