Thunder Bay and northwestern Ontario face an October heat wave this weekend with temperatures up to 10°C above average, Environment Canada warns.
Record-High Temperatures Expected This Weekend
Thunder Bay and much of northwestern Ontario are set to experience unseasonably warm weather this Saturday and Sunday. Environment Canada forecasts daytime highs reaching the upper 20s Celsius, about 10 degrees above the seasonal average.
Warm Air Brings Extended Comfort Day and Night
Meteorologist Steven Flisfeder explained that the warmth will persist not only during the day but also overnight. “The biggest story for this weekend across most of the northwest and much of the north in general will be very warm temperatures,” he said.
Southern Systems Drive Heat Northward
Flisfeder said two unique weather patterns are responsible for the influx of warmth. “High pressure southeast of northwestern Ontario combined with low pressure to the north is pushing moist, warm air up from the southern United States and even the Gulf of Mexico,” he said.
Weekend Activities May Benefit from the Heat
For those with docks to remove at campsites or gardens to tend, the weekend offers ideal conditions. The warm, sunny weather provides a rare October opportunity for outdoor tasks.
Heat Wave Expected to Be Short-Lived
Residents should not expect the warmth to last beyond the weekend. Daytime temperatures are forecast to return to seasonal norms by the middle of next week, Flisfeder noted.
