Showers continue this morning across a wide swath of southern Ontario and Quebec as a warm front lies over the region. There is even some strong thunderstorms embedded in the rain including one just moving ashore of Lake Ontario into the GTA. Some of theses storms even have the likelihood of a waterspout, primarily over Lakes Erie and Huron, closer to the spin of low pressure. This front will be the focus for heavy showers and storms most of the day into the overnight and Saturday. It won't rain all the time, but when it does it could be heavy. A general, and much needed, 25-50mm (1-2 inches) is forecast by Saturday evening. More is possible in training thunderstorms, especially across the mountains of New York and Vermont. Yesterday flash flooding was even reported in Essex County, New York. That same treat remains possible today. Sunday will feature more clouds and showers before the low pressure and fronts move east of the region late in the day. Temperatures will remain warm and muggy during the weekend with highs along and south of the front up near 25 to 27C (75-80F) in Montreal and warm lows around 20C (68F).
Montreal was warm on Thursday despite the clouds with a high here on L'Ile Perrot of 27C and about 5.3mm of rain. I could almost here my lawn saying thank you.

Atlantic Update:
The tropics have become very active as we head into the heart of the hurricane season. Tropical Storm Ernesto is raining out over Veracruz State in Mexico. Meanwhile tropical depression 7 should become Tropical Storm Gordon sometime over the weekend while following a path very similar to Ernesto towards the Windward Islands and off towards Jamaica and the Yucatan. There is also another area of interest just moving off the African coast heading west that shows signs of development according to the NHC.
