Unsettled weather expected for Canada Day in Montreal

Happy Canada Day!
Saturday turned out to be a decent day across Eastern Ontario and Southern Quebec. Montreal managed to slip into the warm sector in the afternoon, with clearing skies and quickly warming temperatures into the upper 20s. We have a warm, muggy and at time thundery week ahead. (Valley Weather Photo)

The heavy rain expected over the weekend managed to fall mainly north of the Montreal region, leaving us in the warm sector of the system on Saturday afternoon. The result was a muggy high of 28C (83F) and a rather pleasant afternoon after the morning thundery rains. In terms of rainfall, between 15 and 20mm fell across the city, bringing the monthly total for June up to 40mm, which is still well-below the long-term average of 83.6mm.

We will end the month of June with plenty of sunshine and very warm temperatures, into the low 30s for many on Monday. The warm and humid air will remain through the evening and into the Canada Day holiday, with lows of only 21C (70F) forecast for Montreal. An advancing frontal boundary will set the stage for more widespread showers and thunderstorms from late this evening into Tuesday. Mother Natures fireworks!

Temperatures will remain warm along with muggy conditions Tuesday, with highs reaching 26C (79F). The balance of the week will be rather unsettled, with temperatures at or slightly above normal for early July, along with the risk of afternoon showers or thunderstorms. Humidity levels will remain moderate, so while conditions will feel muggy, it will not be oppressive like last week. In other words, typical July weather for Montreal. The warm and muggy air will persist into next weekend, with a renewed threat of thunderstorms arriving by Sunday.

Enjoy the Canada Day Holiday!
