FORECAST DISCUSSION
A decaying line of thunderstorms is expected to cross into Northwestern Ontario from Manitoba just after midnight during the early hours of Monday morning. There is an isolated severe risk associated with this line, but the timing should limit the overall severe threat to 90 km/h wind gusts and quarter-sized hail.
Later on Monday, there is an additional severe risk to the east around Armstrong and west of Thunder Bay. An isolated tornado can’t be ruled out. Non-severe storms are also possible around the Quebec border in Northeastern Ontario.
