Some thunderstorms may be severe in nature, bringing heavy downpours, gusty winds, and even the possibility for hail. There is even a slight chance for rotation in some of the thunderstorm cells.
The temperature in Montreal on Tuesday is expected to be a seasonable 26 degrees Celsius but humidity will make it feel more like 34.
The thunderstorm threat in Montreal will be present through Tuesday afternoon and early Tuesday evening. Skies will clear out through the evening hours of Tuesday and sunshine will return on Wednesday.
