A ridge of high pressure will provide southern Quebec and eastern Ontario with three days of near perfect summer weather. Temperatures will be near the normal high of 25C (77F) with perfect overnight lows near 16C (60F). The humidity levels will be low and no precipitation is forecast until Sunday for Montreal. As the ridge slides east on Saturday low pressure will approach from the Ohio Valley and Great Lakes. At this time this system appears to be rather strong for late June and will begin a period of unsettled weather into the middle portion of next week and possibly the Canada Day holiday. On Sunday expect steady rain, in excess of 25mm (1 inch), along with gusty winds and cool temperatures.

Manitoba Tornado
While we have decent weather forecast here in Montreal, strong thunderstorms will produce severe weather from the upper Midwest into the middle Atlantic states today. It has been a stormy few days from Saskatchewan and Manitoba south into the Dakotas and points east towards Illinois. Numerous tornadoes were observed over the last 48 hours including several in southern Manitoba on Wednesday. Large hail also fell along with heavy rain and flash flooding. At one point on Wednesday a massive swirling cluster of storms stretched over 50,000 feet into the atmosphere and covered the entire state of Iowa. Thousands were left without power in sweltering heat from Illinois to New Jersey as the storms pressed south and east. More are forecast today with millions in the path of the potential severe storms.
