Severe Thunderstorm Watch

A severe thunderstorm watch is in effect for southern Quebec and eastern Ontario this evening. As expected warm air surged into the region today with the exception of here in the St. Lawrence Valley where we remain at a chilly 13C (55F) due to a persistent northeast wind. Meanwhile both Sherbrooke and Champlain, New York to our south hit 26C today or 79F. Meanwhile Ottawa was up to 22C. Tonight a cold front is slicing into that warm and humid air with heavy thunderstorms developing along the front in Ontario. The threat for severe weather will exist until midnight. Afterwards look for rain and moderating temperatures in Montreal overnight. Expect 25mm or more of rain with these storms in the next few hours.

A sever thunderstorm watch is also in effect for St. Lawrence, Clinton and Franklin counties in northern New York until 4am Thursday. Heavy rain along with snow melt at higher elevations has swollen many rivers and creeks in the region as well as Lake Champlain. Flood warnings remain in effect.
