As of Aug. 6, there are about 750 active Canadian wildfires, with at least 190 labeled “out of control,” according to the Canadian Interagency Forest Fire Centre. More than 16 million acres (6.8 million hectares) of land have been scorched this year, making this one of Canada’s worst wildfire seasons on record.

An upper-level ridge of high pressure will control the forecast all the way through the end of the week, but as a suddenly flow starts to move in by the time we get to Friday and looking ahead into the upcoming weekend, we will dial-in more summer heat, and more humidity into the forecast.
