The storm system that affected the region yesterday producing strong winds and heavy rainfall from Ontario to Atlantic Canada, continues to meander northeast of Montreal this morning. Light rain is still falling in the city after about 40mm in the last 36 hours. Peak winds in Montreal approached 70km/h with the storm. There were also some decent thunderstorms yesterday afternoon that developed in New York state and swept across the city from the south. They produced torrential rains and strong winds around 4pm. Some minor flooding along roadways was reported slowing the evening commute, but little else. In Ontario the storm produced heavy rain as well with 78mm at Hamilton. Peak winds in the GTA were around 80km/h, stronger along the immediate Great Lakes shorelines. Tree damage and power outages were reported. The same storm system also produced heavy rain in Atlantic Canada with 110.6mm of rain in Halifax.
The weekend in southern Quebec looks typical for late October. While it will not be a washout by any means, there will be a chance of a persistent annoyance shower or two on both Saturday and Sunday. We may see a few sunny breaks, but don't count on too much sunshine. Temperatures will be near normal with highs around 11C and lows around 6C.
