Toronto and Montreal have felt the impact of an unusual weather pattern this September, marked by an extended dry spell. After weeks of rain, the cities have seen their longest stretch of clear skies in 2024. But relief may finally be on the way, as experts predict rain for the weekend, breaking the lengthy drought.
Longest Dry Streak Finally Ending
Both Toronto and Montreal experienced a remarkable change in weather this month. As of September 20, Toronto recorded 11 consecutive days without rain, surpassing its previous dry streak of seven days from early February. Montreal has seen an even longer stretch, remaining dry for 16 days. Ottawa, while slightly better off, has gone a week without measurable precipitation.
- Toronto Dry Days: 11
- Montreal Dry Days: 16
- Ottawa Dry Days: 7
The absence of rain has been particularly striking following the cities’ wettest summer on record. Toronto exceeded its average summer rainfall, accumulating more than 475 millimeters by mid-August—well above the previous record of 396.2 millimeters.
What’s Causing the Dry Weather?
Meteorologists attribute the persistent dry conditions to a resilient high-pressure ridge that settled over Eastern Canada. This created a blockage, preventing storm systems from moving through the area. However, this pattern is now beginning to break down, promising a shift in the weather.
Bill Coulter, a meteorologist with CP24, discussed the potential for changing conditions. “Expect more seasonable temperatures with the risk of showers late in the day. Tuesday and Wednesday look damp, with an early autumn fresh feel,” he said.
Set for a Stormy Weekend
The forecast suggests that the dry spell will likely end this weekend. A weak disturbance crossing the Great Lakes could bring showers and thunderstorms to southern Ontario.
- Storm Timeline:
– Saturday: Chance of rain and thunderstorms, mainly in southwestern Ontario and the Greater Toronto Area.
– Monday: An increased likelihood of rain as more systems move towards the region.
– Tuesday/Wednesday: Precipitation expected to reach Montreal as well.
While Saturday’s thunderstorms might bring heavy rain and gusty winds, it is not predicted to ruin the day completely. Residents are advised to carry an umbrella as they go about their plans.
Looking Ahead: Rainfall Predictions
Despite the uncertainty regarding the exact timing and amount of rainfall, indications are clear that both Toronto and Montreal should brace for wetter weather. This change is a welcome relief after such a dry September.
- September Rainfall Stats:
– Historically, Toronto sees about 75 millimeters of rain in September.
– This month, the recorded rainfall has been less than five millimeters, raising concerns about setting records for dryness.
Both cities will likely see a shift next week with the passage of multiple low-pressure systems sweeping across from the U.S. By Tuesday and Wednesday, rain is anticipated to extend towards Montreal.
Meteorologists will continue monitoring the weather patterns over the weekend and into next week, providing updates as new information becomes available.
What to Expect Post-Rain
Following the precipitation is a return to more seasonal temperatures, which many residents are looking forward to. As fall approaches, the blend of rain and cooler air will contribute to a refreshing change after the dry spell.
As we transition into autumn, it’s clear this month has presented unique weather challenges for both cities. Residents in Toronto and Montreal can look forward to the rain returning and the hope that it will bring much-needed relief to the nearing end of a lengthy dry stretch.
