An intense, nearly stationary lake-effect snow band sets up off southern Lake Huron overnight and some models (like the Canadian HRDPS) give London perhaps 30+ cm by late Tuesday morning. Given so many leaves still on trees this could be a major problem. Keeping an eye on this! #ONstorm #LdnOnt

A lesser-known Farmers’ Almanac will fold after 2 centuries, citing money trouble
The Maine-based publication, not to be confused with the even older Old Farmer’s Almanac in neighboring New Hampshire, was first printed in 1818.

It’s begun. Just saw the first snowflakes of the season in Londontario. Could see up to 10 cm by Tuesday, and likely more in typical snowbelt areas. #WinterIsComing

A lot of folks in Ontario seem to have missed this news. There is no good take on it. The CAs are science based with domains defined by watersheds and they are locally accountable.

The details may be different, but all models are in agreement that the lake-effect snow machine kicks in early next week. Will very likely be 15+ centimetres in some of the snowbelt regions. Get those winter tires on! :-) #WinterIsComing #ONstorm

A few surprise low-CAPE high-shear supercells yesterday NW of Toronto. Weak rotation aloft and not much at lower levels. But severe hail reported at various locations. Maybe up to 3 cm diameter. In some places covering the ground. Among the most severe storms of the year in those areas. #ONstorm

It's been interesting watching what the various models do with the remnants of #Melissa - the Canadian GDPS has been persistent with a western track through Newfoundland. All other models took it east, but are now bending toward the GDPS solution, and taking aim at St. John's early Sun morning.

Claims to be from #HurricaneMelissa in the town of Black River, Jamaica - which is on the southwest side of the island. If so, that's some catastrophic surge. Thoughts are with all Jamaicans!

The worst of storm surges - 200mph winds literally blowing the sea onto the land. #HurricaneMelissa

The NTP has confirmed nine new Quebec tornadoes for 2025 based on our end-of-season satellite review, assisted by an AI detection algorithm. The damage in each case was only to trees, with one tornado rated EF2 and eight rated EF1.

Attended the closing night of Shakespeare's As You Like It last night at Stratford, ON's Festival Theatre. All the world's indeed a stage, and I was pleasantly surprised at the production. In particular, the songs that @ronsexsmith.bsky.social had a hand in creating - just the right touch. Congrats!

If Carney is waiting for a sign, this is it - the orange tyrant can cut off good-faith negotiations whenever his feelings get hurt, whenever he likes. He could do the same *after* an agreement is 'signed'. There's no point in negotiating with the US to try to save the trade relationship. It's over.
