Unsettled weather week ahead for Montreal

Above & below: This past weekend was near perfect with seasonable highs near 26C (79F) and comfortable lows around 15C (59F). Abundant sunshine and low humidity made it perfect for anything outdoors. The great weather brought plenty of cars and visitors to Sainte-Anne-de-Bellevue for the annual Cruisin at the Boardwalk car show. (ValleyWX Photos)

 Most of Ontario and Quebec remain in an active weather pattern with frequent frontal systems bringing us showers and thunderstorms. The intense heat and humidity with values exceeding 37C (100F) remains well south of our region across the middle Atlantic and southeast US states. This has left us with moderate temperatures in the middle 20's during the day and mid teens overnight.

Adding to the influx of moisture will be the development early this week of a tropical system in the Gulf of Mexico. This storm is expected to develop in the next day or so and move into east Texas or Louisiana. Tropical moisture will stream northeast along the frontal boundary and produce rainfall by next weekend. Until then we are looking at a mix of sunshine and clouds with frequent showers and thunderstorms today into late Tuesday and once again Thursday into Friday. No one period will be wet for too long but it wont be a perfect week either for outdoor activity. This pattern is expected to hold well into next week. Temperatures will try to reach the middle 20's but it will depend on how much sunshine we get.
