| A pop-up thunderstorm moves into the Montreal burrough of Saint-Laurent on the afternoon of Monday, May 26. The storm produced torrential rain, hail and lighting. Fortunately the cell was fast moving and as a result the impacts were minimal. Monday was the 11th consecutive day with measurable precipitation at Trudeau Airport. (Valley Weather) |
Wednesday may have been the nicest day in May. Widespread sunshine allowed the temperature to rise to 27.4C (81F) at Trudeau Airport in Montreal. It was a rare moment in what has become a dull and wet spring. In May to date, 111.2mm of rain has fallen, that included precipitation on 11 consecutive days up to and including this past Monday. It has rained on 19 of the 28 days so far this month.
On Monday, some decent isolated, pop up thunderstorms put down heavy rain, lots of lightning and even some small hail during the afternoon hours. All the moisture has had at least a positive impact on the fire season in southern Quebec. There are only three active fires in the province at this time. Such is not the case elsewhere in Canada where massive wildfires have resulted in evacuations across parts of Manitoba and Saskatchewan.
The trend of unsettled weekend weather across southern Quebec will continue as we head into June. A weak warm front will lift north on Thursday, introducing some humid air. Spotty showers are possible into Friday. On Saturday, another unseasonably strong Nor'Easter will move north into New England, with abundant Atlantic moisture. At this time, it appears that Montreal and the Ottawa Valley will remain on the western edge of the storm. While heavy rain is expected in Vermont and the Eastern Townships on Saturday, Montreal should only have scattered showers and gusty northeast winds. Sunday should be partly cloudy, with perhaps a shower or two and milder temperatures.
Highs from Thursday into Sunday will drop into the upper teens from Wednesday's summer warmth. Lows will be in the lower teens. Briefly looking ahead to next week, we can expect warmer, but also a more humid airmass to arrive. As a result showers and thunderstorms will remain a real possibility in the St. Lawrence Valley.

I honestly didn't mind the rain and the clouds as well as the cooler temperatures. I am more affected by the extreme heat and humidity we get as well as the wildfires in Quebec.
