| From weather.com, strong storms are possible today from the St. Lawrence Valley into New England and New York. |
5pm Update: Most of the activity with today's cold front is well east of Montreal and into Vermont and eastern New England. The watch for Montreal and points west has been allowed to expire. Some strong storms did occur, especially in the north end of Montreal and the Richelieu Valley. Some hail and heavy rain was observed. Here on the West Island we had some gusty showers with winds over 55km/h, but no thunder or lightning. I have yet to hear thunder this year.
We have a very humid and foggy morning in Montreal today as an unstable, mild and moist air mass is in place. Temperatures are around 13C here on L'Ile Perrot with a forecast high of 22C. The fog will burn off by mid morning and sunshine and warm temperatures are expected into the early afternoon. A strong cold front with a history of severe weather is forecast to move into Eastern Ontario around 2pm and sweep southeast across the St. Lawrence Valley and into upstate New York by 6pm. Yesterday this same front prompted tornado and severe thunderstorm warnings for northwest Ontario including Timmins. Along and ahead of the front look for showers and the occasional strong thunderstorm to develop. The storms will be capable of strong winds and even hail. The cold front should clear the area overnight with clearing skies on Thursday and much drier and cooler weather. At this time the long Victoria Day weekend looks awesome with sunshine and temperatures warming to the high 20's by Monday.
