STORM2K

Tomorrow is the 26th anniversary of the May 31, 1985 Ontario/USA tornado outbreak, which 12 died in Ontario and over $100million in damage.

Anyway, we have a see text risk tomorrow, but The Weather Network said a severe weather scenario might develop tomorrow over southern Ontario with even the possibility of tornadoes. All thanks to a cold front or something.

Is that true? How bad could it get here tomorrow. I have no school tomorrow, so I could do a chase if it looks promising.

88 people died in the entire outbreak, and it is the 21st anniversary of the outbreak. It is a very difficult call IMO. I believe that if everything lines up perfectly, we could see a large-scale event. However, that is a huge if.

Most of the activity today is daytime heating convective, so tornadoes IMO are not a major threat (large hail and straight-line winds primarily).

Watches are starting to be issued. The SPC is slower now...

TORNADO WATCH



People across southwestern Ontario are being urged to keep an eye on the sky.

Tornado watches and warnings are in effect across large stretches of the region.

Environment Canada says its radar picked up what seems to be a tornado about 30 kilometres west-northwest of Toronto's Pearson airport.

There have been no reports of an actual tornado touching down anywhere.

Environment Canada warns that weather conditions can change on a dime.

The agency says people in the affected region should stay alert and be close to appropriate shelter.

It was exactly 21 years ago today that a tornado ripped through Barrie, killing eight people and destroying 300 homes.

These tornadoes were probably landspouts or gustnadoes. I just don't see how the environment today can produce a legit tornado with the weak shear and low SRH.

Oh, I think lake breeze convergent thunderstorms played a role. This storm was apparant with a few that formed. Unique to southern Ontario. Funnel clouds were spotted in Wellesley Township just west of Kitchener and here.

A large funnel cloud was spotted 200 feet from the ground for 10 minutes just west of Waterloo a few kms during the tornado warning. I had no way to know that a big tornado could have hit.

This city really needs tornado sirens, the power was out for the warning so no one had warning. There has been 12 tornado warnings since 2000 for this county, that is 2 a year. That sounds like enough to warrant tornado sirens for here.

Every community in a tornado zone should have one. That is most everyone east of the Rockies.
