First summer warmth of the year for Montreal

Warmer, summer-like temperatures are expected for the long holiday weekend across southern Ontario and Quebec. Enjoy! 

It has certainly been a chilly April and May to date, with temperatures stuck in the low to middle teens most days. While not unpleasant, many have been waiting for shorts and sandals weather to arrive, and it is here just in time for the Victoria Day long weekend.

The temperature reached 25.6C (78F) in Montreal on Thursday afternoon, the warmest so far in 2024. A weak frontal boundary will lift across the region on Friday, and we are already seeing some south to north moving showers and isolated thunderstorms across eastern Ontario this morning. That threat remains with us most of the day, but any precipitation will be widely scattered in nature.

Late this evening through midnight, another weak boundary will slide across the region, with an increased threat of showers and perhaps a thunderstorm for southern Quebec. Temperatures will remain very mild, 24C (75F) Friday, with a low into early Saturday morning of 15C (60F).

Skies will clear out Saturday morning as a ridge of high pressure moves into the region. Warmer temperatures will develop, along with light winds. Highs will be near 27C (80F), Saturday and Sunday. By Monday southerly winds will develop, with and increase in temperatures and humidity. Expect summer-like highs in the upper 20s, along with humidex values climbing into the low 30s.

By Wednesday of next week, we will see a frontal system and low pressure arrive from central Canada, along with showers and thunderstorms. Temperatures will drop to more seasonable levels.

Of note, with the warmer weather arriving, many will be enjoying the parks and waterways around the region. Keep in mind that water temperatures are still very cold, and hypothermia can occur quickly.
