Happy Canada Day!
Another long weekend is upon us, with an extended period of summery weather expected. Warm and humid air will stream into southern Quebec on Thursday and Friday, with temperatures approaching 30C on Canada Day. Humidex values will be in the middle 30s despite expected cloud cover on Friday. Thursday so far has been a touch cooler than expected as stubborn clouds have prevailed most of the day. We should see some breaks overnight and into Friday morning.
Winds will increase as well on Friday, out of the southwest 30 to 50km/h, drawing in the warm and sticky airmass from the southern US. A few showers and isolated thunderstorm are possible late Friday along a frontal boundary before sunshine returns on Saturday. We can then expect a stretch of ideal summer weather as high pressure builds into southern Quebec. Expect seasonable weather, with high temperatures in the upper 20s and lows in the teens. Sunshine is forecast into at least Tuesday of next week.

| Showers and thunderstorms move into Montreal on Wednesday afternoon. June has been a very wet month across southern Quebec, with 170mm of rain falling at Trudeau Airport. |
We can certainly use a break from the wet weather, with nearly 170mm of rain falling at Trudeau Airport during the month of June. The long-term normal for the month is 87mm. I have measured 175.2mm of rain at my home on Ile Perrot since June 1st.
Be safe and enjoy the Canada Day and July 4th long holiday weekend.
