Weather Alert: Brace for 30-50cm Snowfall and Strong Winds
A significant weather event is on the horizon for the Waterloo Region, as Environment Canada has issued a snow squall watch. This alarming forecast warns of snowfall accumulation ranging from 30 to 50 centimeters.
Possible Impact of the Upcoming Storm
The weather phenomenon is anticipated to commence on Thursday morning and last until Saturday. Residents should prepare for variable snowfall totals across different areas.
In addition to heavy snowfall, strong wind gusts are also expected. These winds could reach speeds between 70 to 80 kilometers per hour. Such conditions could lead to local utility outages and pose risks for high-sided vehicles. Loose objects may be displaced by the high winds.
Weather Conditions and Causes
The storm is influenced by a “wobbly polar vortex” moving from the Prairies, along with an Alberta clipper system. This combination is expected to affect both northern and southern regions of Ontario.
- Start Date: Thursday morning
- End Date: Saturday
- Snowfall Amount: 30 to 50 cm
- Wind Gusts: 70 to 80 km/h
Chief Meteorologist Natasha Ramsahai noted that the unusual weather event results from sudden stratospheric warming (SSW). This phenomenon weakens the typical wind patterns, allowing for cold air spills.
Ramsahai indicated that occurrences of SSW at this time of year are rare, having happened only a few times in the past seven decades. Furthermore, the ongoing La Niña is contributing to this shift toward colder conditions.
Winter Outlook
The winter outlook for the Great Lakes region suggests that the first part of winter will be considerably cold. However, a milder climate is expected in early 2026. Residents should remain vigilant as the winter season progresses, particularly with the snow squalls returning starting Thursday.
