Residents in Sarnia, Ontario, should prepare for a return to wintry conditions as a quick-moving weather system is forecast to bring significant snow to the region on Friday, March 13, 2026. According to The Weather Network, the area could see between 5 and 20 centimetres of snowfall throughout the day.
This cross-country low-pressure system is expected to make travel slick and difficult for local drivers. Forecasters warn that road conditions will likely become “dicey” as the snow spreads across Southwestern Ontario.
The upcoming storm is part of an unpredictable weather pattern that has seen temperatures in the province swing between warm and cold throughout the month. This sudden return to winter-like hazards follows a period of milder conditions in the region.
Local teams from the City of Sarnia and Lambton County public works departments will be monitoring the roads to manage safety as the system passes through. Residents are advised to leave extra time for their commutes and prepare for potential travel delays on Friday.
