Spring bites back with frost risk in Ontario this week

Well, Ontario spring is anything but consistent from 20° to negative temperatures. The next week we’ll be dealing with potentially both. We have a 0° forecasted low for April 25th, that’s Wednesday night. The latest 0° we’ve seen is May 28th, 1949. So we’re not doing too bad. But typically for Ontario, the frost season ends about the end of April to the beginning of May. However, it’s going to be a little bit extended potentially this week as we have a lobe of cold Arctic air descending over Ontario all the way down to regions like Lake Lake Erie. Bringing in some negative temperatures. So the low temperatures overnight for Wednesday is 0° in Toronto. As we head further north, you’ll see those -3 in Peterborough, Peterborough -4 in Huntsville. And as we really get into cottage country, we could get into those minus fives, but it is very short lived. We’re getting that push out of cold air and we’re getting a resurgence of nice warm air by the weekend and to finish off May. So although you see that dip there, just know we’re resurfacing to seasonal temperatures.
