Nice evening kayak on the Humber River near Lake Ontario yesterday. The fall colours are really starting to come into the Toronto area now.

Some very warm weather in Eastern Ontario and Southern Quebec with temps into the mid 20s. The edge of the unsettled weather is now nosing into the GTA with a squall riding the leading edge of the cold front. High winds and local isolated damage possible #ONstorm

Happy #Thanksgiving!

Enjoying the #Woodbridge #Fair today 😀

Frost risk for #Toronto proper and much of the #GTA again tonight. I’ve temporarily stuffed all the overwintering plants into the greenhouse. I’ll have to organize it in the coming days when I have some time. They should be able to go back outside tomorrow.

Please note: During today's attack by the Russian Federation targeting targets located in Ukrainian territory, our airspace was repeatedly violated by drones. An operation is underway to identify and neutralize the targets. At the behest of the Operational Commander of the Armed Forces,

Here are some photos I took of the #Toronto #CNE #Airshow #CIAS showing Mike and Samantha Tryggvason doing their Wingwalker thing. This was my favourite part of the show today.

Photos are with a Canon 5DSr and 800mm lens. 📷 🔭

These kids were really into jumping off the rail bridge in Port Credit. What can I say, I'll never forgo a good show while kayaking.

All that rain did wonders yesterday.

Rain and crepuscular rays... I'm so excited, it's like a tornado for me LOL

Rain two days in a row is godsend…

I was reading this book and I've found more similarities than differences...

Oh this polygon is small compared to some of the warning polygons in northern and Northwestern Ontario that are HUGE.

The obvious problem is that you have one singular storm but you're putting a warning out for areas that could be almost one hundred km away.

A few images from different social media platforms of the tornado near Goderich earlier this evening associated with a supercell as it came ashore.

Milton storm is all but dead... just rainy mush at this point.

Still plenty of time for some hidden surprises but the overall risk is relatively low.

Hard to tell based on radar alone but the supercell between Bayfield and Goderich is certainly struggling now, rotation still present but radar shows a diminished (for the moment) threat.

Rotation on the Bayfield storm waning, but the Milton storm looking more tight.

Might have to go for a drive shortly. At dinner with the wife at Beertown... LOL

Another storm to keep an eye on that could potentially start wrapping up nd tightening is just north of Milton. No risk attm, but needs to be observed.

Now that's a solid tornado vortex signature if I've ever seen one out over Lake Huron.

Like I said, warm front doing all the heavy lifting as far as wind shear is concerned.

The 12Z WRF-NAM is painting a supercell on the warm front tomorrow afternoon running from Flint Michigan into Chatham-Kent Ontario.

What's more important is to understand that the environment along the warm front features good shear and winds veering to the ESE + jet support #ONstorm #ONWX

I was debating heading to SW Ontario yesterday. I decided against it due to overall timing. Had a weak shelf in the GTA but zero severe weather.

Tornado warnings ahead of the storm complex making landfall near Britt, ON. The rotation does not show up well in the base velocity product but shows up well in the storm relative velocity product.

Risk of rain-wrapped fast moving tornadoes in cottage country today (and Algonquin Park), high winds and flooding rain in other areas. The biggest risk today appears to be wind damage. Those out camping need to stay especially weather aware. #ONstorm #ONwx
