Raging wildfires in Western Canada have spread smoke over much of the northern/central U.S. this evening. The plume of smoke now extends over 2000 km, and it will likely move into the Eastern U.S. over the next few days, with the summer blue skies turning a milky white. You can see what the smoke looks like from Fargo, ND here. Very dry conditions coupled with recent extreme heat have caused the fires to become quite large.
The 60 Day rainfall across Western Canada has been way below average, as the map from Agricultural Canada shows:
Some good news: The rain chances will rise and temperatures will drop over the next 3 days, and this should allow firefighters to get better control of the fires.
