Record high on Monday for Montreal

SEVERE THUNDERSTORM WATCH metro Montreal for the day today for strong thunderstorms capable of heavy rain.

It has been a rather warm and muggy 24 hours in southern Quebec with temperatures in the low 30's on Monday afternoon. The warmth included a record 30.4C (87F) in both Ottawa and Montreal breaking the record high of 30C set back in 1970. Overnight lows remained very warm between 19C and 22C (66-72F). Today the region is expecting a cold front to slice through the muggy air this afternoon producing widespread showers and thunderstorms. I am not expecting severe weather with the storms today, that is hail or very strong winds, but the rain will be heavy. Some of the storms may produce upwards of 25-50mm (1-2 inches) of rainfall locally which could lead to some flash flooding in poor drainage areas. A watch or warning may be needed later today for portions of eastern Ontario and southwestern Quebec. Watch my Twitter feed for more details. Some sunshine may push us up to a muggy high of 27C (81F) today.

Once the front clears the region we can expect cooler temperatures on Wednesday, 22C, with showers and unsettled weather into Friday. The weekend is expected to be sunny both days with warm high temperatures of 27 to 30C (80-85F) both days.
