Special weather statement in effect for:
- Niagara Falls – Welland – Southern Niagara Region
- St. Catharines – Grimsby – Northern Niagara Region
Winter weather threatening this week.
Although it’s officially spring, winter weather is still normal this time of year around the Great Lakes. A weak disturbance will bring a little snow or rain to most of Southern Ontario today. However, a stronger low pressure system is expected to emerge from Colorado and affect the region Wednesday through Thursday.
Although there is uncertainty with the exact track of the storm, the latest guidance suggests significant snow is possible over areas extending from Lake Huron and Georgian Bay across Lake Simcoe into Eastern Ontario. Freezing rain and ice pellets will be possible across a large portion of Southwestern Ontario, the Golden Horseshoe and parts of Eastern Ontario. Rain is expected closer to Lake Erie.
Environment Canada meteorologists are watching the evolution of this storm closely. Even a slight northward or southward shift in the track of the low will affect how much snow, freezing rain or rain falls at any particular location.
Motorists should be prepared for a return to hazardous winter driving conditions this week, especially in areas that receive freezing rain or snow.
