Tornado Watch for Eastern Ontario

There are already some big thunderstorms developing over northeastern Ontario along a cold front. This afternoon as the front settles into the hot and unstable air mass in eastern Ontario, strong thunderstorms and isolated tornadoes are possible. This is only a watch at this time. It is very hot already with temperatures over 30C in Montreal and humidex values pushing 40C before noon. The dew point at my house on L'Ile Perrot is a tropical 25C (77F) highest this summer. Strong winds are gusting over 60km/h in Montreal as well.
