The Calm After the Storm in Southwestern Ontario

Tornado warnings were issued in London and Oxford County yesterday evening.

OXFORD - It's the calm after the storm in southwestern Ontario.

We had quite the system move through the region yesterday evening. Environment Canada issued a tornado warning at around 5:20 p.m. in the London area and Warning Preparedness Meteorologist Monica Vaswani says that is where most of the damage occurred.

"There were reports of many downed trees and power outages. Even in places like St. Thomas we had a couple of reports of windows blown out in vehicles and there was also a semi truck on its side."

The storm system associated with the tornado warning headed east, and that's why a warning was issued in Oxford County at around 6:06 p.m.. This warning highlighted several locations where rotations were possible based on the radar, including Burgessville, but Vaswani says nothing was confirmed for those areas.

She adds the Northern Tornadoes Project investigates based on where the damage occurred.

"They are currently in the process of doing their damage surveys. Specifically, southeast of London there were reports of a tornado in the Belmont area, so I believe that general region is where they are canvassing to determine if a tornado did in fact occur."

Looking at the forecast, Vaswani says we should have a break from stormy conditions at least for a few days.

"We don't really have any threat of thunderstorms really for most of southern Ontario over the next couple of days. Saturday is the first day that looks like there is some potential because there is a new system coming in from the United States into southwestern Ontario, but it's too early to say if its going to be severe weather. Once we get into the work week next week, we start to get into temperatures in the 20s again, so I would say next week is when you need to keep an eye on the sky a little bit more again because those warmer temperatures will likely bring the threat of some showers or thunderstorms."
