Severe Weather possible today in Ontario

Keep a weather eye on the sky today in Ottawa, Montreal and along the Seaway. There is a moderate risk of severe thunderstorm activity as a strong cold front moves into very muggy air. This morning the temperature in Kemptville rose from 12C (54F) at 6am to 22C (72F) at 8am. You could smell the warm air flooding in on southeast winds. It will reach 31C today before the cold front moves in. The front has a history of severe weather across the Great Lakes and Midwest US. Environment Canada has already posted a Watch for our area at the following link:

And from the National Weather Service Office in Vermont

The best threat will be between 3-7pm in our area. Strong winds, heavy rain and even hail are possible.
