Southern Ontario can expect 5-15 mm of rainfall, while regions east of Georgian Bay could see 15-30 mm.
Northeastern Ontario, including areas like Timmins, is forecast to see 5-15 cm of snowfall as cold air interacts with the system. Residents in these areas should prepare for potentially hazardous road conditions.
More potent system arrives Saturday
A strengthening Texas low will move across Ontario on Saturday, bringing significant moisture and varying weather impacts across the province. This system will deliver another round of rain to parts of southern Ontario, while high pressure from the north keeps temperatures below freezing, resulting in widespread snowfall for northern regions.
Central Ontario is expected to see 10-20 cm of snow, though locations within this heavy snow band will be refined closer to the event. Residents in southern and eastern Ontario should also prepare for the possibility of freezing rain through Saturday afternoon and evening, with cold surface air in place.
