SW ON, Eastern ON, S PQ Summer Heat, Weekend of May 26-27

Hi All,

Just curious about something...EC and TWN are calling for temperatures on the 26-27th of May to be in the low 30°'s C. When I look at the GFS , it shows temps in the low-mid 20's, and MyForecast also shows this. Which models are EC and TWN using, and what do folks more knowledgeable than me have to say about next weekend's forecast? What are the chances of T-storms? I'm seeing a slight chance based on the convective and CAPE, but if it is going to be that hot with more humidity (maybe up to 80% on Sunday), is there a greater chance than what the early models are showing?

I'm learning a lot about meteorology and forecasting from this forum, and I appreciate any guidance that those with more experience can provide.

March 9 Snow Squalls

EC has posted snow squall warnings in Ontario for areas from London-Middlesex up to the Bruce, over to Orilia, and across to Niagara. 2-4 CM, but higher amounts I suspect in some areas. Post your observations and pictures. Predictions?

Environment Canada's Special Weather Statement (non S. Ontario information deleted)

"Discussion of thunderstorm potential.

Form a squall line and become severe with damaging winds large hail
and heavy downpours. An isolated tornado is also possible.

Tonight..Scattered thunderstorms over Southern Ontario. There is a
risk of severe thunderstorms from London to Niagara including Lake
Erie in the evening with damaging winds, hail and torrential
downpours as the main threats. An isolated tornado is also possible
early in the evening. Thunderstorms over southcentral and Eastern
Ontario may approach severe limits due to torrential downpours and
gusty winds."

Post your observations. I'll upload any interesting pictures that I may take during the day. I'd be interested in seeing shots taken by other folks around the region.

Stay safe!

July 17 S. Ontario T-storms

Just west of London the rumbles of thunder have been continuous - literally - for the past 45 minutes. Severe thunderstorm watches have been issued and the sky is getting really dark to the NW. Looks like a great show is about to begin!

Comments? Forecasts? How does it look for the London region? The wind direction looks like it's lining up to potentially hit Kitchener/Waterloo and London like it did a couple of years ago. It would be nice, though not so nice for the commuters.
