Warmer - humid weather for Ontario & Quebec

A spectacular shot of a massive waterspout (tornado over water) in the Gulf of Mexico moving inland near Grand Isle, Louisiana on Wednesday afternoon. The storm was as much as 1 mile wide and damaged one home and power lines.

Summer heat and humidity will begin building into Ontario and Quebec as early as Friday. Today will be spectacular in Montreal with warm temperatures near 25C, light winds and abundant sunshine. On Friday a warm front will begin to lift across Ontario and Quebec with showers and thunderstorms developing. They won't reach Montreal until early Saturday. The weekend at this time looks ok, with more sun than clouds. There will be periods of thunderstorms especially in the late afternoon, but it will not be a washout. This will be typical late June & July weather with humidity on the rise and high temperature pushing 30C (86F) by Sunday and into next week. Overnight lows will warm as well to nearly 20C by Monday.

There has been plenty of strong thunderstorms across western Canada over the last 48 hours. Heavy rain, in some cases over 75mm has produced flash flooding in southern Alberta. Meanwhile tornadoes and hail have been reported in southwest Saskatchewan near the Cypress Hills. Slow moving low pressure has been the culprit with more strong storms expected today in southern Saskatchewan and Manitoba.

Tropical Storm Barry
The tropics are active once again with the development of tropical storm Barry in the southern Gulf of Mexico. The system is small in nature with 45mph winds, located about 30 miles east of Veracruz, Mexico. Landfall is expected today with the main threat being heavy rains and flash flooding. Forecasters expect 5-10 inches of rainfall along Barry's path which is more than enough to cause deadly flash floods and mudslides.
