Warm and humid weekend for Montreal

Heat and humidity will surge into southern Ontario and Quebec this weekend. (AccuWeather)
After a couple of cooler days with lower humidity levels in southern Quebec, the heat will begin to build once again today heading into the weekend. We are starting what is typically the biggest holiday period in Quebec as many take summer vacations. The weather will also be typical for middle July as warm and very humid air invades southern Quebec and Ontario. Today will be sunny but with increasing clouds as a warm front moves east from the Great Lakes, the high should be from 25 to 28C (77 to 82F). Showers and even an isolated thunderstorm will develop overnight and Saturday across eastern Ontario into Quebec and New York as temperatures remain mild overnight at 19C (66F). Saturday will be muggy and warm with showers and thunderstorms and a high near 27C (81F). Sunday and Monday look similar with more scattered storms, warm and humid with highs in the upper 20's.

There is a risk of some severe weather late Sunday and Monday. I understand that I have mentioned this often this summer and seemingly the storms have avoided metro Montreal. They have however affected other portions of southern Quebec, eastern Ontario and northern New England/NY. It is important to remember that thunderstorm activity can be very isolated. That does not diminish the dangers from lightning, hail  and winds. If storms are forecast, or a weather watch or warning is in effect, and you have any outdoor activity planned, be aware of the sky. Also when the thunder roars go indoors. Lightning injuries and fatalities have been on the rise across North America this year.
