Blazing hot summer across Canada from coast to coast

The searing heat continues to impact large areas of Canada, with a focus on the west this weekend. A cold front moved through southern Quebec late Thursday, with isolated thunderstorms. A fast moving storm put down 15mm of rain in 20 minutes across Ile Perrot and Vaudreuil. The cold front brought in the coolest air of the month, with a morning low of 16C (61F) in Montreal. More importantly, the week long oppressive humidity finally broke as well.

The upcoming weekend will be warm once again, close to 30C (86F), but humidity levels should remain manageable. Sunshine will dominate in southern Quebec through Sunday evening, when our next chance for showers should arrive.

In Western Canada, hot high pressure is shattering records form B.C. to Saskatchewan. On Thursday, over 40 record high temperatures were established across the three provinces, including 40.8C (106F) at Kamloops, B.C. As I am writing this blog, temperatures once again are in the high 30s and low 40s across western Canada. Accompanying the heat has been dense smoke from forest fires burning across B.C. The smoke has lowered visibility from B.C. to western Ontario. Air quality alerts are in effect across western Canada, and southward into North Dakota, Montana and Minnesota.

In B.C. over 475 wildfires are burning, many being started from lightning strikes associated with dry thunderstorms. Rain is desperately needed. The high heat and extremely dry weather stretches from southern Canada to California, with thousands upon thousands of acres being consumed by fire. While Quebec and Ontario have been dealing with high humidity, dangerously low levels are being recorded out west, in many case lower than 10 percent.
