Heavy Rain along the 401 at Brockville on Saturday

Deja Vu

We remain in a very moist and unstable air mass this morning with temperatures approaching 25C and Relative Humidity's in the 70 and 80 percent range. It very steamy and the risk of thunderstorms is very real across Ontario, Quebec and the northern US. A severe thunderstorm watch is in effect for Kemptville and Eastern Ontario, while a flash flood watch has been posted for Eastern New York and Northern Vermont. There is a serious threat that some of these storms will produce heavy flooding rains. The potential exists for more than 25mm in an hour.

Yesterday another 15mm of rain fell in Kempville as our wet June moves on. Overnight a line of fierce thunderstorms moved through Kemptville and other parts of the region. The lightning cut power in places and triggered some fire alarms. KFD was called out to South Branch Elementary around 2:30am where they encountered broken windows. I am not clear if it was storm related, at this time, but the OPP were called as well. Edwardsburg-Cardinal firefighters were called to a potential fire in Cardinal. Again it may be weather related. The lightning was intense and frequent with these storms. More are expected today.
