What a storm!

Just check out these pics of Saturday night’s storm. That cold front pushed in quick with winds clocking in over 100 km/h. Cold air, being dense, displaces warm air which is less dense and forces it aloft. When a cold front moves in that fast it pushes the retreating warm air aloft, allowing for the formation of massive storm clouds called cumulonimbus clouds. These clouds can reach as high as 50, 000 feet where they tap into strong mid-level jet streams that really get things spinning. Saturday’s front pushed in very quickly and packed a lot of energy. Very exciting for weather nerds but very damaging to people’s property and very dangerous. The Port Perry Curling Club will need extensive repairs to their roof and the vehicle to the left…well, that’s a write off. Even here in Peterborough, though less intense, localized wind gusts were strong enough to take out a massive tree. (My condolences to Lori and Gary of Peterborough on the loss of their tree.

Well looking at the latest GFS run to the left, things are looking oddly similar. Just check out Friday’s blog where we first talked about the possibility of a weekend storm and you’ll notice a lot of similarities. A strong Bermuda high is kicking in warm air from the south making for a great daytime high…but another cold front looks to displace that warm air tonight with showers and the possibility of some thunderstorm activity. The good news is that this frontal precipitation is short lived and things look to be clear again tomorrow night into Wednesday.

See you tonight on Newswatch at 6pm.
