Well if this is ever going to be true, temps are going to have to jump by 17 degrees. I'm near the lake and the thermometer is showing 10C - I can't see it being 17 degrees higher elsewhere in the city !

OK, looks like we're underway. Active watches now include the following: "The main concerns are large hail up to 3 centimetres and damaging wind gusts to 100 km/h. There will also be an increasing threat during the afternoon for an isolated tornado. This watch may be upgraded to a tornado watch as the storms develop, if their evolution dictate a higher tornado risk."

I don't see the numbers (in NAM, at 21Z) supporting large hail (in Eastern Ontario, anyway - not enough lift), but ran a thumbnail SWEAT index for that time and came up with a 449! If nothing else, should get a pretty good light show tonight. I think that northern NY state will see plenty of action tonight.

Get those cameras ready!

Not too sure why EC issued severe thunderstorm warnings for the hazards of large hail, damaging winds and reported tornadoes on April 27th....

Heck, a little girl was crushed by a fallen tree in Kitchener which some are speculating may have been a continuation of the Ayr tornado...

They should have issued a tornado warning for Perth, Oxford, Waterloo, Wellington, Brant, Hamilton, Halton, and Dufferin counties. Not all at once, but that is where each individual couplet was evident on Buffalo radar.

But, a tornado warning these days from Environment Canada is probably asking too much... especially since this blunder...

Maybe Environment Canada is now like pre 1950s America where they believed forecasting a tornado would cause panic...

Code:
SEVERE THUNDERSTORM WARNING
ISSUED BY ENVIRONMENT CANADA
AT 4:52 PM EDT SUNDAY 1 AUGUST 2010.
---------------------------------------------------------------------
SEVERE THUNDERSTORM WARNING FOR:
=NEW= WINDSOR - LEAMINGTON - ESSEX COUNTY.

---------------------------------------------------------------------
==DISCUSSION==
A FUNNEL CLOUD HAS BEEN REPORTED IN CENTRAL ESSEX COUNTY.  THERE IS
THE RISK THAT THIS FUNNEL COULD REACH THE GROUND AND CAUSE LOCALIZED
WIND DAMAGE.

I agree. There were some weird cloud formations were i was with some evidence of some rotation on radar. I didnt notice any rotation overhead though...
