Roller coaster week

The weather will improve today as the clean up continues at the St. Catherine Locks along the St. Lawrence Seaway on Montreal's South Shore. The CSL ship the Richelieu dumped about 75 tonnes of oil into the seaway on Monday forcing closure to all ship traffic. According to the St. Lawrence Seaway Management Corporation, the seaway should reopen by tomorrow. (Montreal Gazette photo)

The one constant this week will be the muggy and warm air. Otherwise showers, clouds and sun will mix for the balance of the week as a series of frontal boundaries affects eastern Ontario and Quebec. yesterday most of the the thunderstorm action remained well south and west of Montreal passing through the Seaway and south into New York State. The main feature of these storms was the very heavy rain and sporadic flash flooding. Over 40mm of rain fell in many locations from Cornwall and Massena south and east. Despite the ominous forecast Montreal had just a few millimetres of light showers late in the afternoon with a rumble or two of thunder. The storms that passed south of Montreal late Monday night produced an 80km/h wind gust at the airport in Dorval and snapped some hydro poles and tree branches. The threat for thunderstorms today is minimal, but hey you never know this summer.
