SEVERE THUNDERSTORM WATCH
Deepening low pressure is moving into southwest Ontario this morning. This system is trailing a potent cold front behind it that has been the focus for severe thunderstorms. This morning we have already had some thunder in Montreal, but the main event will occur later this afternoon along the cold front. For that reason Environment Canada has taken the unusual step of issuing a severe thunderstorm watch several hours before the effective threat. The watch is in effect for most of southern Quebec from 2pm until 8pm. The main area of low pressure will lift into the Ottawa Valley with heavy rain, up to 50mm. This morning thunderstorms are spreading across Ontario and into the National Capital Region. The threat for severe weather also applies to New England. The strong storms will move into Vermont later today and this evening. In advance of the system this morning, strong southerly winds will develop and gust over 50km/h in Montreal and up to 70km/h in the Richelieu Valley. Temperatures will warm into the mid to upper 20's today before a sharp drop this evening and Sunday into the teens. It will feel like fall on Sunday with a cold northwest wind, showers and high of only 19C
