Ontario will see a tale of two seasons this week. Some areas will see significant snowfall and some ice buildup, while others are on alert for multiple rounds of thunderstorms–some of which could be severe
In true spring fashion, Ontario is in the crosshairs of a potent storm that will deliver impacts of reflective of the current season and winter.
The storm’s clash of air masses will deliver summer-like warmth to some southern regions and lingering winter chill to others in northern sections. Rounds of snow, ice, rain, and thunderstorms will hit the province Monday, Tuesday, and into Wednesday morning.

As April approaches, spring’s inconsistent pattern looks set to persist. While temperatures will trend in the right direction, with warmer peaks and less intense cold dips, consistently warm, above-normal weather is not anticipated as we move deeper into the month.
Northern Ontario: Snow and ice risks Tuesday
A developing system will bring a mix of snow and ice to northern Ontario starting early Tuesday.
Snow is expected to spread across areas including Thunder Bay and regions east of Lake Superior in the pre-dawn hours, with varying intensities through the day as waves of precipitation move in. The heaviest snowfall is anticipated Tuesday afternoon near Lake Superior, with accumulations ranging from 5-15 cm across areas north and east of the lake.
Farther south, freezing rain and ice pellets may begin Tuesday morning in communities northeast of Georgian Bay, extending across the Nickel Belt.
