Feeling like September in Montreal

Despite high pressure trying to nudge into southern Quebec, it remains partly cloudy and cool today. Cold air aloft has generated cloud cover this afternoon in Montreal, as well as a few showers. The temperature is cool for early August, sitting at 22C (72F). Skies will clear out after sunset tonight with cool overnight lows in the low to middle teens (50 to 60F). On Friday we should finally break away from the stubborn low in northern Quebec and see more sun than clouds. Temperatures will warm up to 25C (77F). At this time the weekend looks nearly perfect with abundant sunshine and high temperatures from 25 to 28C (77-83F). Overnight lows will range form 12 to 14C (52-56F) under clear skies with just some patchy fog possible.  A strong fall-like low pressure system is forecast to develop along the southeast coast of the US and move northeast affecting Atlantic Canada. At this time is is expected to remain well east of our area. With the exception of this upcoming Sunday when we may hit 28C (83F), the early September feel to the weather will persist well into next week. More rain is forecast next week as a surge of moisture moves north from the Gulf of Mexico.

Thunderstorms in southern Quebec on Wednesday afternoon developed north of Montreal and passed to our east. Large hail was reported along Highway 40 east of Repentigny as well as heavy rain. The bulk of the severe weather affected mainly the Townships and Beauce for the third day in a row.

Massive thunderstorms dropped tons of hail on Calgary late Tuesday afternoon. Widespread damage was reported.

In western Canada fierce thunderstorms swept through southern Alberta late on Tuesday, August 4th. In a matter of minutes the storms dumped heavy rain and hail on Calgary, knocking out power to over 35,000 customers and producing flash floods. Numerous roads were impassable and the ground was covered in a thick blanket of hail. The hail pounded trees, cars and gardens causing widespread damage and stranding motorists. Strong winds toppled trees, power line and utility poles. Another round of severe weather hit Calgary on Wednesday causing more flooding.
