Southern Ontario is set to experience significant snowfall and rain after enjoying some milder days, as two weather systems move through the region, with snowfall accumulating over the course of the week.
According to Environment Canada, the first wave of winter weather began on February 27, 2025, and is already causing headaches for commuters. The initial system is bringing periods of snow across southern Ontario, particularly impacting areas like Brampton, Mississauga, and Hamilton, with projections of snowfall measuring up to five centimeters. Meanwhile, the weather advisory warns travelers of slippery roads resulting from the melting snowpack. "Be prepared to adjust your driving with changing road conditions. If visibility is reduced... slow down, watch for tail lights ahead and be prepared to stop," said Environment and Climate Change Canada (ECCC).
The Greater Toronto Area (GTA) isn't exempt from these harsh conditions. The potential for more snow continues as Thursday progresses, transitioning to light rain or freezing drizzle along the Lake Ontario shoreline. Residents should expect difficult driving conditions as the accumulation creates challenges for evening commuters.
Looking forward to later this week, heavier snowfall is expected on February 28. Reports suggest this system originated from the Pacific Ocean and has since reorganized, set to deliver up to 10-15 cm of snow to southern Ontario. The Weather Network has indicated, "The snow will reach the GTA by late Friday afternoon, just in time to impact the evening commute," calling attention to the potential difficulties faced by those heading home from work.
Many areas, particularly north of the QEW, can expect significant wet snow accumulation. Estimates for parts of northern Ontario, such as Thunder Bay, predict measurement between 20-25 cm, leading to impactful travel disruptions along key routes including the Trans-Canada Highway.
Though the weekend doesn't appear to bring any relief, with forecasts predicting persistent cold and flurries, residents are reminded to stay wary of changing weather patterns. The unusual convergence of temperatures gives way to continued winter weather, forcing commuters to plan accordingly for any potential delays.
On February 27, areas like Pickering and Oshawa are also facing the onslaught of winter precipitation, with similar forecasts of 5 cm of snow throughout the day. Conditions will worsen as the temperature drops to -6°C overnight, accentuated by significant wind chill factors making it feel as cold as -12°C.
Environment Canada's predictions are clear: winter is not finished yet. It is recommended for all residents to stay updated on their local weather alerts and check the latest road conditions before heading out to avoid hazardous situations.
The alerts serve as grave reminders as southern Ontario gears up for the heaviest snowfall this winter. With travel advisories already issued, many are reflecting on just how quickly the winter grip has reasserted itself.
Indeed, locals are expressing feelings of frustration as they transition from warmth back to enduring wintery conditions. Some took to social media, posting joking remarks, "Auuuuughhhhhhh! It’s back! The snow is back! More snow! Noooooooo!" highlighting the abrupt return of winter.
This week's changing weather transforms fully what only earlier seemed like the arrival of spring. Local forecasts will continue tracking this pattern, guiding residents as they navigate through potentially treacherous conditions.
With the latest forecasts showing no signs of easing soon, it's becoming clear: winter weather is ensemble at play, reinforcing the necessity for caution on the road as southern Ontario braces for anticipated snowstorms throughout the weekend.
