Thunderstorms are possible across Northern Ontario in the morning and later in the day. The first round of storms will come just after midnight in Northwestern Ontario as a line of storms tracks into the region from Manitoba. These storms will slowly decay as they move eastward throughout Thursday's overnight and early morning hours.
A more potent storm threat is expected to materialize by the afternoon in Northeastern Ontario. Isolated severe storms will develop somewhere around Chapleau and Timmins and track to the east/southeast during the late afternoon and early evening. The strongest threat is right along the Quebec border with up to 3cm size hail and wind gusts in excess of 100km/h.
An isolated tornado can’t be ruled out in locations including Timmins, Cochrane, Englehart and Kapuskasing (as shown below).
