Rare November thunderstorms unleash hail in southern Ontario
On November 4, 2023, southern Ontario experienced a rare weather event as thunderstorms swept across the region, resulting in significant hail. This occurrence resembled summertime storms, complete with loonie-sized hail in areas like Brampton. Weather conditions were atypical for November, with radar images revealing a striking contrast to the usual winter landscape.
Unusual Thunderstorm Activity in Ontario
This widespread thunderstorm activity is particularly rare for November in southern Ontario. While seasonal temperatures largely prevailed, some areas in southwestern Ontario saw daytime temperatures approach 20 degrees Celsius. Meteorologists noted the unique atmospheric conditions that contributed to this phenomenon.
Factors Contributing to Thunderstorms
A warm front across the region played a crucial role. It lifted air into a pocket of unstable air aloft, where temperatures decreased significantly with altitude. This elevated instability facilitated the vertical growth of storms, even with limited surface heating typical for this time of year.
- Strong wind shear was a key factor, allowing storms to develop longer updrafts.
- These updrafts collect supercooled droplets, which, when combined with ice particles, contribute to the growth of hailstones.
- Low freezing levels ensured that hail could survive as it fell, despite environmental challenges.
As a result, the thunderstorms continued to thrive, extracting maximum instability from the upper atmosphere. While the Greater Toronto Area (GTA) experienced a dreary day, the sky above was incredibly active, producing hail normally associated with warmer months.
Impact on the Region
The storms were a surprise for many residents, as they defied typical November weather patterns. The event serves as a reminder of the increasingly unpredictable nature of weather systems in the region.
