Near record warmth surges into Ontario & Quebec

What a difference just a few days can make. The same regions that had frost warnings Monday night are now looking at high heat and humidity, possibly record breaking. Montreal is forecasting a high of 30C today, the record is 31.5C set in 1978, and 32C or 90F forecast for Friday. Along with the heat will come summer like humidity that will push humidex values close to 40C. There may be isolated thunderstorms each afternoon as the heat builds. Yesterday strong storms swept across the central portion of the city as well as through Vaudreuil and Valleyfield. The storms that affected those regions even produced a funnel cloud late in the afternoon near Cassleman, Ontario. The storms that rolled across Montreal brought about 6mm of rain here on L'Ile Perrot but as much as 25mm fell in the West Island and Downtown core during the evening rush hour. Strong storms also affected New England with numerous reports of hail, flash flooding and a possible tornado in southern Vermont.

The rain that fell in Burlington, Vermont helped them to establish a new record for the wettest May ever. This month 8.74 inches has fallen so far surpassing the 2011 record of 8.67 inches. Record keeping dates back to 1884. Keep in mind how dry, almost drought like the first two weeks of the month were for all of us.
