THUNDER BAY — The heat dome that moved into Northwestern Ontario on the weekend broke temperature records in Thunder Bay and several other locations in the region.
Environment Canada recorded a high of 34.3 C at Thunder Bay Airport on Saturday, surpassing the previous record established in 2012.
Pickle Lake and Geraldton also established new maximums for Saturday, with highs of 35.2 C and 33.6 C respectively.
At Red Lake, the existing record of 32.7 C for July 3 was tied.
More records may be threatened across the region on Monday, but a dramatic cooling will quickly take place Tuesday, with Thunder Bay projected to reach only 19 C.
Temperatures are expected to rebound to the mid-20s by the weekend.
Environment Canada's outlook through mid-July suggests above-normal temperatures and drier-than-normal conditions in Northwestern Ontario.
June was considerably warmer than normal in Thunder Bay, with a monthly mean temperature of 17 C, three degrees higher than the long-term average.
