In a repeat of Monday, storms will be likely in Saskatchewan again Tuesday and continuing into early Wednesday. This time, however, the threat has increased to a slight risk across a large swath of Southern Saskatchewan which could see as much as 100mm of rain, the occasional wind gust exceeding 90km/h, up to toonie-size hail and the possibility of an isolated tornado.
The initial storm activity is anticipated to start mid-afternoon Tuesday in the west with some isolated cells, but things will begin to ramp up as we approach the evening hours. This is when we expect these individual storm cells to begin to merge, creating clusters of storms that will push eastward across the southern half of the province throughout the evening and overnight and into the early morning hours of Wednesday.
The main threat from these storms will be the hail, with up to toonie-size likely, as well as wind gusts that could reach 100km/h. There is also the possibility of training thunderstorms, multiple storms that follow the same track, so flooding will be a concern as some areas could see up to 100mm of rain in only a few hours. It seems unlikely based on the data, but an isolated tornado can not be completely ruled out.
