A 'classic' spring storm is heading to Ontario later this week, bringing rain to the south and snow to the north.

Here are four things you need to know.

1. TIMING
"The system is is expected to move into southern Ontario Thursday afternoon, where it will persist until very early Saturday morning," says Weather Network meteorologist Dayna Vettese.

"It will hit northern Ontario Thursday evening and remain in the area until Saturday afternoon."

2. PRECIPITATION AMOUNTS

Between 15 and 30 mm of rain will fall across southern Ontario, with 30+ mm expected in the Niagara region and along the Lake Erie shoreline.

"Higher amounts are possible in southwestern Ontario if a thunderstorm occurs," Vettese adds.

Further north, between 15-30 cm of snow is forecast to fall.

3. WILL THERE BE WIND?

Yes.

"Strong, gusty southwest winds will accompany this system with gusts between 70 and 90 km/h over Lake Huron and Georgian Bay shorelines and gusts between 50 and 70 km/h along Lake Erie and Ontario shorelines, increasing up to 80 km/h on Saturday," Vettese says.

Wind gusts will be in the 20 to 40 km/h range across northern Ontario.

4. WHAT IS THE FORECAST CONFIDENCE?

"Forecast confidence is high that a Colorado Low will bring classic spring conditions to Ontario," Vettese says, "but forecast confidence is low regarding the occurrence of thunderstorms on Friday."
