Southern Ontario is bracing for what forecasters describe as significant winter weather, with snow squall warnings issued across various regions amounting to predictions of up to 60 cm of snow by the end of the week. Environment Canada has alerted residents from Bracebridge to Barrie, as well as parts of cottage country, to prepare for hazardous winter conditions starting Thursday.
The weather agency’s warning emphasizes the potential for blowing snow and dramatically reduced visibility, with northwest winds gusting up to 60 km/h contributing to treacherous conditions. "Northwest winds gusting up to 60 km/h can result in blowing snow and significantly reduced visibility at times," Environment Canada stated. This warning covers areas like Owen Sound and Kawartha Lakes, extending to major regions including Peterborough and Belleville.
Rain and snow from the preceding weather systems throughout the week have set the stage for this heavy lake-effect snow, expected to persist through the weekend. The advisory indicates regions, particularly near Georgian Bay, might see severe accumulations. "Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow," Environment Canada cautioned. Accumulating snow could make roadways difficult to navigate, affecting travel plans.
Across southern Ontario, including cities like Mississauga, Brampton, Halton, and Hamilton, snow accumulations of 5 to 10 cm are expected, as weather advisories have been issued to warn residents about slippery conditions. A travel advisory confirms heavy snowfall is also expected for these regions, forecasted to start Thursday morning and continue throughout the day. Environment and Climate Change Canada noted, "Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Take extra care when walking or driving in affected areas."
Travel conditions will likely worsen as snowfall intensifies. Drivers are advised to monitor road conditions and adjust their plans accordingly, particularly if traveling to areas farther north where up to 60 cm of snow may fall.
Reflecting on past weather events, Geoff Coulson, from Environment Canada, remarked, "Some of these accumulations are definitely historic; these amounts certainly rival many of the biggest storms we’ve ever had." He recalls how recent storms have dramatically shaken the expectations of winter weather this early in the season, emphasizing the unusual conditions following abnormally mild fall temperatures.
Global News meteorologist Anthony Farnell expressed disbelief at the rapid snow accumulation, stating, "These are numbers... occurring really early and all at once," which is notable for winter conditions. The warming before the storm resulted from record warm temperatures over the Great Lakes and Georgian Bay, creating the perfect mix for intense snowfalls.
The snow squalls not only impact driving conditions but will also likely lead to school delays or cancellations as the region adjusts to the results of this potent storm system. Parents and guardians should keep abreast of local advisories as conditions evolve. If driving is necessary, the agency advises drivers to exercise caution and avoid any non-essential travels due to the expected severe road conditions.
This winter storm is also part of broader weather activities stemming from polar air mass systems sweeping down from the Prairies. These weather patterns are indicative of climate influences causing erratic weather throughout the winter months. Coupled with high winds, snow squalls tend to lead to drastic changes, making conditions vary significantly over short distances.
Citizens planning to venture outside are advised to dress warmly and be prepared for sub-zero temperatures and wind chills. Friday and the weekend are expected to bring continued potential for snow and freezing temperatures, with weather forecasts showing lows hovering between -4 C and -9 C across the region, and daytime highs fluctuated around freezing.
Officials are advising residents to stay updated and prepared as communities brace for the impact of this storm. Monitoring local forecasts and respecting public safety recommendations will be key to ensuring safety throughout what is anticipated to be one of the more significant winter storms southern Ontario has seen this season.
Residents are reminded to take extra precautions when traveling or engaging outdoor activities as the winter weather persists, ensuring they remain safe during the upcoming snowstorm.
