Currently at Toronto Pearson: 11. High today: 23.
In Environment Canada's list of Ontario weather stations that broke high temperature records for today, there are eighteen (!) that broke the old record by more than ten degrees (!). (Some of these may not have records going back very far, but some--e.g., Kapuskasing--go back as far as Pearson.) EC is calling for a high of 26 in Toronto on Wednesday, which would be twenty degrees above normal. That's pretty hard to do, and would be right around the highest temperature ever recorded in March at Pearson, which was 25.6, on March 28, 1945. (March is actually the only month that Pearson has recorded a high temperature more than twenty degrees above the average high for the month.) The snow is gone from Accuweather's forecast for next week; now it's just down to the high side of normal.
Curious thing: despite the general rise in average temperatures over the last couple of decades, there hasn't been a monthly-record high set at Pearson since 1988, when it hit 37.6 in July. Two more monthly records were set in the '80s, none in the '70s (which isn't surprising; what is surprising is that only one monthly-record low was set in the '70s), one in the '60s, five in the '50s, and two in the '40s (including the all-time high of 38.3 on August 25, 1948). At the downtown weather station (which has records back to the mid-19th century, as opposed to Pearson's going back to the '30s), the last monthly-high record was set in December of 1982; there's one in the '70s, four in the '60s, two in the '50s, one in the '40s, one in the '30s (the all-time record of 40.6 on July 8, 1936), one in the '10s, and one in the 1840s. (Ten of the twelve monthly-record lows downtown are from the 19th century. If Toronto weather reports used the downtown station as the default station of record rather than the airport, it would be much more difficult to set "record low temperatures" in Toronto. The last monthly-low record downtown was set in 1933: -30 on December 29. The other 20th-century one was in 1923: -15 on April 1.)
