Non-zero tornado threat over central parts of southern ON with this convective line developing now. I've found that the SPC Mesonanalysis 'tornadic tilting and stretching parameter' seems to work well in such situations. And it's showing enhanced potential. Will be keeping an eye on this... #ONstorm

Deskilling is real.
This is the world generative AI peddlers long for, one where people are incompetent without their service.
Don't outsource your brain to this shit. You'll regret it.

✈️ Wheels up for a 10-day vacation in northern Italy!
How long into the flight should I wait to show my wife this image of the Po Valley during peak season? I can feel the eye rolls already

Hold up, there is a peculiarity in the footage with boosted contrast. This slender elephant-trunk-looking feature was present for 30sec and is in the right spot to be a funnel cloud. Inflow is entering the tor-warned circulation from the right side of the photo. #onwx thoughts?

Some great lightning from the weekend's SW Ontario chase! This is from the backside of the decaying tornado-warned circulation.
It was great to return to the area (first chase there since 2020) and arrive *just* in time for the action.

The tornado-warned circulation from a couple of evenings ago in SW Ontario. The drone recorded the storm circulation for +20mins and it did not indicate any touchdowns (even with boosted contrast). Tricky when the circulation was often obscured by heavy rain #onwx

Beautiful shelf passing north of Hanover from a couple of nights ago. This is looking northwest towards Chesley where notable radar-indicated rotation was buried deep in the precipitation. #onwx

Sunday was well spent in the Adirondacks High Peak district.
Hard to believe that these views are only a four-hour drive away, and a reminder not to take them for granted. Tbh this trail kicked my ass...3500 steep feet of elevation gain over rough, untamed forest terrain

Clearing is moving into Central Ontario. I won’t make it to the jungles of Haliburton-Bancroft but a safe bet for Sev Tstorms is the OTT River Valley where there is a boundary, and marginally enhanced moisture pooling/directional shear. Good chase terrain nearby in Shawville QC. Lets go

Ah yes, the classic westward cutoff low moving from *check notes* Labrador to Pikes Peak...

Tues chasing expectations: low, considering the narrow time window for SFC-based severe in Central Ontario. As usual with these early-season setups, the CAPE may not advect quite as far north as modelled. It's April afterall...
Tues chasing excitement: high. Because it's April?!

What an unreal couple days in the Texas panhandle for chasing slow-moving tornadic supercells. This is the stuff I use my PTO for

I acknowledge this is a “way-too-soon” post. But hey, it’s April, and we’re jonesing for a chase.
The last few GFS runs have hinted at the season’s first substantial severe threat next week for the Canadian side of the lower Great Lakes. Keep an eye on the trough’s evolution through the weekend.

One year ago I got to witness my favourite spectacle, but better yet, this time it was with my favourite people. They rallied hard when I told them we have to leave Belleville immediately in order to make it to Quebec’s Eastern townships and avoid being clouded over.

"White Lightning"
A March thunderstorm sending bolts over the melting ice of Lake Huron near the Bruce Peninsula with the shoreline lined with nature’s rare blue ice sentinels.

Drone timelapse of massive HP tornado warned supercell as it came into Hughes Springs, TX, that I tracked down using the @RadarOmega app earlier this evening.
Check out that incredible rain cooled air inflow channel feeding into the massive rain wrapped circulation. Pure meteorological beauty.

The NTP has completed a third Tornado Warning Performance Assessment for Canada, this time covering 2023-2024. It includes a 'report card' on progress.
And we're happy to report that there has been progress - the overall score has improved enough to earn a 'C'.

Going to be hard for anyone to beat this footage in 2025. Insane yet composed.
BREAKING NOW: Massive tornado on the ground in Arkansas.
A TORNADO EMERGENCY is underway for Blytheville, Trumann, Lake City and Gosnell, Arkansas
