Selon Brett Anderson: Based on our latest thinking, here is my best estimate for the time window of severe thunderstorms in selected cities for Friday. Keep in mind, there could be spotty storms before and after these times. This is an estimate for most likely period for the strongest storms. Ottawa, Ontario..... 2-6 p.m. Friday Toronto, Ontario.... 4-7 p.m. Friday Windsor, Ontario..... 3-6 p.m. Friday London, Ontario.... 4-7 p.m. Friday Barrie, Ontario..... 3-5 p.m. Friday Hamilton, Ontario.... 5-8 p.m. Friday Peterborough, Ontario... 4-7 p.m. Friday Kingston, Ontario.... 6-8 p.m. Friday Montreal, Quebec.... 5-8 p.m. Friday Quebec City, Quebec... 4-7 p.m. Friday northwest New Brunswick... 6-8 p.m. Friday The front does slow its forward speed a little more than what we thought for Saturday, which is not surprising since it is July and the strength of the high pressure ridge to the south. With that in mind, we may see some thunderstorms early Saturday across extreme southern Ontario as the cold front approaches then pushes south later in the afternoon, though the main threat for severe weather will be across the Northeast U.S.
