Forecaster: Brennen Perry

A system that initially appeared likely to track through our region and bring widespread 6-12cm of snow accumulation on Thursday is now trending further south resulting in much less of an impact on Southern Ontario. The heaviest precipitation will be found along the Lake Erie shoreline and into Eastern Ontario where 6-12cm of accumulation is still expected as the system focuses on Upstate New York with heavy snowfall. Snowfall will begin just before midnight for the Windsor area and slowly encompass areas along the northern Lake Erie shoreline early Thursday morning. A secondary area of snowfall will sweep through Southern Ontario from Northeastern Ontario bringing snowfall accumulation between 2-4cm (maybe 6cm closer to the GTA and Lake Huron) early in the morning.

Persistent snowfall will continue for most of the morning along the Lake Erie shoreline and into Extreme Eastern Ontario although accumulation will be quite light. Another push of snowfall will come during the afternoon as snowfall tracks across Lake Huron from Michigan which could bring a few centimetres of additional snowfall to areas south of Lake Simcoe. Snow will begin to taper off for most areas by the dinner hour. Although we may see snow squalls develop overnight and into Friday for areas southeast of Lake Huron as cold Arctic air flows into the region. More details on that in a separate outlook for Friday.
