Arctic air will be on a southward move next week to bring Canada a major pattern changeup, a healthy reminder that winter is just around the corner. https://ow.ly/PFiR50Xtgis

Gobsmaking sea level rise coming folks.. sooner than you think 🌊 Calving icebergs unleash hidden wave forces that supercharge Greenland’s melt and push the ice sheet closer to collapse Massive hidden waves are rapidly melting Greenland’s glaciers www.sciencedaily.com/releases/202...

Pro tip: make sure to put coffee in your chemex/french press/machine before pouring the hot water through. It tastes much better that way.

November 17-19, 2014: A massive lake effect snow event impacted Buffalo, New York. Over the course of 3 days, bands from Lake Erie produced snowfall rates up to 3-6" per hour. Totals in many areas peaked at over five feet. Tragically, thirteen people were killed.

Can't even use Downdetector to see if #Cloudflare is down because Cloudflare is down 🤣

🥇With a mean wind of 28km/h, yesterday was #Ottawa's windiest Halloween since records began in 1953. #YowWx #OttWeather #YOW #OttNews #ONWx

We have graupel! Sounded like hail but my colleague told me it looks like graupel as there are steep lapse rates over Georgian Bay with cooler air aloft. #ONstorm #ONwx

Yes, we are developing several different types of wind estimation tools that can be used in cases where the traditional EF scale can’t or is limited. Expect progress on that in the off-season.

The CSSL/NTP assisted the US National Weather Service (NWS) with their upgrading of the official rating of the June 2025 Enderlin, ND tornado from EF3 to EF5. Announced by the NWS today, it’s the first EF5-rated tornado in the US since 2013. Details here: uwo.ca/ntp/blog/202... Image B. Emfinger

Here's the radar at right about the time of the the EF5 damage near Enderlin, ND, from KMVX (Fargo). Intense azimuthal shear. Given there was a massive, high-intensity QLCS bearing down on the area, I have to wonder if the QLCS had an influence on the supercell/tornado intensity at Enderlin. #NDwx

NTP partner 'The Weather Network' also has an article on the Enderlin, ND EF5 tornado that the NTP helped to rate. www.theweathernetwork.com/en/news/weat...

The @nytimes.com highlighted work from #WesternU's Northern Tornadoes Project to reclassify a tornado that tore through rural North Dakota in June as an EF5, the highest category on the Enhanced Fujita Scale. @westernuntp.bsky.social

The NTP has confirmed five concurrent tornadoes over water (waterspouts) over Lake Erie off Long Point on Oct 21. Details at the NTP blog here: uwo.ca/ntp/blog/202... #ONstorm

The NTP has confirmed a new tornado over water (waterspout) that occurred over Lake Huron northwest of Bayfield, ON yesterday. Details at the NTP blog here: uwo.ca/ntp/blog/202... #ONstorm

The NTP has confirmed a tornado over water (waterspout) that was reported off the coast of Nova Scotia near Rocky Bay on October 25. Details at uwo.ca/ntp/blog/202.... #NSstorm

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. Details: uwo.ca/ntp/blog/202... #meteoQC

Today we have a special blog post on a new NTP tool for AI-assisted satellite review, with the method described by its developer - the NTP's Daniel Butt. The tool is being used experimentally and is already producing results. More on that shortly! uwo.ca/ntp/blog/202...

🤯

Wish I had better shots of it, but it looks like it wasn't a Bridge Creek look-a-like just for show after all.

This is the first F5/EF5-rated tornado in North Dakota in almost 70 years (last F5/EF5 tornado was the Fargo tornado on June 20, 1957)

Yay! 👀

16-17 FEB 2022 - Tornado-Outbreak At least 32 tornadoes occurred over N Central Europe within 20 hours along cold-front storms. One tornado reached IF2.5, and 14 reached IF2 intensity @bramvantveen.bsky.social @federicopavan.bsky.social @alluringstorms.bsky.social @sarahhants.bsky.social

This is awesome!

For some areas, this weekend's atmospheric river event could produce a month's worth of rain in just a few days. #BCStorm

I had some curious onlookers stop by when I was on waterspout patrol early this morning. I don't think they were very interested and went on their way.

Conditions were just right for nearly two-dozen reported waterspouts to dance across portions of the Great Lakes on Sunday.

ESWD - AUGUST 2025: 2171 #severewx reports #wx Fatalities: 25 -- Ligthning: 11 | Floods: 9 | Winds: 5 @bramvantveen.bsky.social @federicopavan.bsky.social @alluringstorms.bsky.social @weatherhistory.bsky.social @rued.com @aaron-stormchase.bsky.social @kreisrhein.bsky.social @meteomabe.bsky.social

I’ll be real with you: not even a Cybertruck owner deserves this

Here's a wind swath for Hurricane #Katrina generated from a parametric model I coded up. Wind speed reduction over land is a generous 30% (the reduction is usually more, but south Florida and south Louisiana offer exceptions). @miamirosenstiel.bsky.social

I’m sure just like the UK this will be used only to protect the kids and will never give governments easy access to censoring what you can view on the internet entirely. 😐 I guess we’ll see how they go about this, if it’s the whole ID verification fiasco as the UK then rip internet.

Burning Man went from desert vibes to desert chaos real quick this week. A powerful dust storm ripped through Nevada’s Black Rock Desert on Monday, sending festivalgoers scrambling to hold down their tents. #BurningMan

It’s going to be really difficult to keep blaming other countries for their fossil fuel emissions when they keep converting to clean energy.

Making them wear high-visibility vests over camo is such a good joke you couldn’t write it

Ik this is probably satire or bait but no joke two restaurants I went too recently in the states had their meals frozen and heated up in an oven. Is this just the norm nowadays? 😭

A fantastic morning with 6 waterspouts counted off the shore of Presqu'ile Provincial Park. Lots of photos and some video to go through. All taken between 6am and 7am EST. Brighton, Ontario #onstorm

Waterspout at sunrise. Shaky video of one of the many waterspouts on Lake Ontario this morning. The one time I don't have my tripod with me. The rope out at the end is so cool. Brighton, Ontario #onstorm

Juicy cell moving S/E over Lake Ontario. 4:30pm Wicklow, Ontario #onstorm

There is a tonne of rain in these cells, but not much action that I can see. Grafton, Ontario #onstorm #shareyourweather

The NTP has confirmed three EF2 tornadoes that occurred in NE Ontario near Englehart on July 12. Satellite imagery was used to identify the tracks of significant tree damage. Details at uwo.ca/ntp/blog/202... #ONstorm

The NTP has confirmed four additional tornadoes over water (waterspouts) that occurred in the Canadian waters of the Great Lakes in August. See the following for details: uwo.ca/ntp/blog/202... #ONstorm

...meh...like other models, not much on the Euro Lightning potential 4cast. meh...🥱 #onwx #onstorm
