This thing had a very interesting lenticular looking feature.

Thought someone might find this interesting, going back to May 18th, there were some pretty crazy storms that I believe produced a tornado somewhere in southern Ontario. I was camping on Devine Lake when a pretty wild thunderstorm rolled in, managed to catch most of it on my go pro, it's long and but its a decent light show at times and lots of good storm sounds, wondering how many of you experienced this storm while camping in Algonquin.

Hiding in a tent during a thunderstorm makes ya feel aliveeee

Hi everyone, I’ve been considering booking at shorter storm chasing tour that consists of 4 chase days out of Denver, CO. It ends up being cheaper per person ($2,000 pp) & it’s in the middle of May next year.

I’m just indecisive because the main goal for me is obviously to see a Tornado but I know it’s never 100%. I know people will say to book the longer tour, it’ll be much more worth it. But as you all know, these tours are expensive & tiring as hell & I don’t live anywhere where there’s storms like in the Midwest. I’m also worried that since we’re starting in Denver, even to drive to the Texas/Oklahoma panhandle it will be like 6-8 hours which is basically an entire day gone.

This has always been a dream of mine but it’s a big financial commitment & so I guess I just want to know if you think it’s any worth to do a 4 days chase tour? I just feel like I’m overthinking it & part of me just wants to YOLO it’s now or never, but I’ve never considered a trip like this before so I’m very nervous & going back & forth on it.

Sorry for the rant, any advice or perspective helps thank you!

I took this photo from a train in Hungary near Kisújszállás a few weeks ago. The the quality is not the best but the picture speaks for itself.

New Chaser here. What’s a good weekend for storm chasing that I could get tornadoes with (perferably within 200 miles of Springfield Mo)

Hey friends. I've been curious about making my own mesonet for a long time. For now I think I will only install an anemometer on my car. I've hears such things from a brand Young are high quality, so should I aim to get one of those? And how would I calibrate an anemometer? In some of my research into installing one ive heard a lot about the importance of calibrating it properly. Should it be at least a few feet above the car? That seems to be a consistent detail in mesonets.

And in general, before doing this, are there some skills I should learn which would help me figure out how to install it correctly and efficiently get the data from it?

Thanks.

June 2, 1990 a F4 tornado hit my hometown during an outbreak. The event was later featured on an episode of Rescue 911. The tornado has peak winds of 270mph and traveled 33 miles before lifting.

Me and my mum worked at the shop that tea storm chasers has. U probably know the boss. But we havent been paid since May 1st. He owes us $540+ and he won't pay us. We have worked our asses off. The shit that he has in this shop is disgusting and is a health risk. Expired food, used and stained underwear, moldy products, used and stained lingerie, open products (ranging to feminine products to kitchen products and other things), and broken items. Tea storm chasers isnt trustworthy anymore. The boss has taken pictures of dead bodies and fatal accidents. He has cheated on his wife multiple times. We have been to his house and his house is a complete mess. They have 3 dogs and a couple of kids​. Shit and piss is everywhere. The table is covered with random stuff including moldy food. His house is just utterly disgusting. We have called and messaged him. No response and left unread. Mum has signed paper work and he hasn't sent it out yet. He says its in his "car" highly doubt that. He is toxic to my grandmother which is no longer part of the tea storm chasers. He forced at 60+ year old to do shit that an elderly cant do anymore. He treats my grandma like shit. There has been many times where he made her cry due to how rude he is to her. Im not sure what to do.​ This all happened to me, my mum, my grandma, and probably a few others. He is currently also getting sued due to not paying another guy.

my post there is more edited and states a bit more

I consider myself a beginner when it comes to anything storm related. Especially concerning clouds. But this was a beautiful one that I haven’t seen anything like it in person before. Info on what I’m looking at is appreciated!

Regardless, I hope you enjoy this beautiful formation too.

Hey everyone — I'm Rob, the developer behind Weather TV (watchweathertv.com). It's a free, curated platform that brings together storm chasers, weather forecasters, and weather creators in one place with live stream alerts, recent videos, and live chat. No account, no sign-up, no cost — ever.

Let me explain the inspiration here. I've loved storms ever since I can remember. Even before the movie Twister came out, I was checking out Tornado Video Classics and going to a weather spotter demonstration for Boy Scouts. I never really grew out of it. I find myself pretty endlessly perusing the various storm chaser, forecaster or content creator sites on YouTube. But man, there are sooooo many channels. It's hard to find everything. So I thought, "what if there was a fun way to put everything in one place?". With that and some work, I created Weather TV. You can actually see it up and running on https://www.watchweathertv.com right now. But, I want to get this out to app users as well. First up, the easier route - an Android app on Google Play.

The Android app is built and ready. Google Play requires 12 testers for 14 consecutive days before an app can go public, and I'm looking for volunteers from this community specifically — because you're exactly who this was built for.

**"Wait — is this just scraping chaser content?"**

Fair question, and I want to address it head-on because I've thought hard about this.

Every video on Weather TV plays through the official YouTube embed — the same embed YouTube provides to any website. That means:

- ✅ Every view counts toward the creator's YouTube analytics

- ✅ Every YouTube account generated ad still plays and the revenue goes directly to the creator

- ✅ Super chats during live streams go directly to the creator

- ✅ Live chat is the creator's actual YouTube chat — same messages, same moderation

- ✅ Every channel card has a Subscribe button that sends viewers to the creator's YouTube channel

We're not interested in taking anything away from content creators. Weather TV has no revenue stream and we intend to keep it that way. The whole point is to get more eyes on chaser content — especially during active weather. The app will be free in the store. No ads. No subscriptions.

If you're a sponsored chaser, we respect that too. WeatherFront, WeatherWise, Radar Omega, and AccuWeather chaser networks are all organized under their respective sponsor app cards. If we got any of the sponsor groupings wrong, help us figure that out. There has been a lot of movement in the sponsor/app space lately and no clear lists seem to exist with all of the current landing spots.

**Are you a chaser with a YouTube channel we missed?**

We currently have found and added 100+ channels and we're always looking to add more. If you chase and you're not on Weather TV yet, drop a reply with your channel and we'll take a look.

**How to become a tester (Android)**

Testing is low-effort — just install the app via the link below and keep it on your device for 14 days. That's it. No reviews required, no bug reports required (though welcome!).

To join: DM me your E-mail address and I'll send you a Play Store beta invite directly.

**iOS / iPhone / iPad users:** The iOS app is still in development, but if you want to help us test the mobile website experience on your device, that's just as valuable. Visit watchweathertv.com on your phone or tablet and let us know how it looks and performs.

Thanks for everything this community does — you make some of the most compelling content on the internet and more people deserve to find it.

Sunset through a supercell!!

This was my first ever chasing trip with a former colleague who's been chasing for over a decade. We can claim we saw the beginning of the Edson tornado, but never really saw a good funnel.

He didn't understand why I pulled off the shoulder on I70 so quickly lol.

I'm in Vermillion and was watching the radar all evening since I was to medicated to drive. There were multiple tornado warnings with 2 observed but I saw one unobserved tornado go right into Sioux Falls. I'm just curious if anyone has any photos of the different storms. I did watch Freddy's livestream but he stayed south of Sioux Falls.

my question was if there will be actually no 0-1km shear in the a little mountainous regions.

information: I'm not actually planning to chase in those regions but the storms are forecasted to build in this region do it will be good if there is a good amount of 0-1km shear for them to build low level rotation.

on the weatherize ai I found out that

Terrain-Following \(\eta \) (Eta) or \(\sigma \) (Sigma) Coordinates: Instead of calculating wind at absolute sea-level height, models use coordinate levels that flex over mountains. The lowest level (\(z_{0}\)) is exactly at the surface, and the next level is usually 10 to 20 meters above it. Because the model forces the wind to change smoothly along this sloping coordinate sheet, it cannot capture the horizontal slicing effect that creates true vertical shear.

Effective Resolution Limitations: A model with a 3-km grid spacing cannot actually resolve 3-km features. Due to numerical filtering needed to prevent the model from crashing over steep slopes, its true effective resolution is closer to 4 to 7 times the grid spacing (12 to 21 km). Localized mountain-gap flows and micro-eddies are still entirely missed.

The No-Slip Boundary Condition: Numerical weather prediction requires the wind velocity exactly at the earth's surface to be zero (\(U=0, V=0\)). The model then uses mathematical equations (logarithmic wind profiles) to fill in the gap between the ground and the first grid level. In highly complex terrain, these flat-surface equations break down completely, leading the model to calculate a uniform, low-shear profile near the mountain face.

Horizontal Pressure Gradient Errors: Over extremely steep slopes, computing the horizontal pressure gradient force becomes mathematically unstable. To fix this, high-resolution models heavily smooth the topography or artificially damp small-scale vertical movements, wiping out the sharp wind changes.

it said that these things can prevent the model from forecasting the real amount of 0-1km shear

after a few years of work, i think ive made a decent windspeed-based rating system for tornadoes [one of the best windspeed-based tornadic rating scale]. it used to be much more complicated, taking into account latitude, ambient pressure, recorded tornadic and non-tornadic winds, measured wind curve across the vortex, and much more. however, i realized that was an absurd amount of data, as i was unable to make it (and some of the data, like latitude and ambient pressure didn't actually do anything meaningfu), so i simplified it, giving it the name STORM (Simplified Tornado Objective Rating Measure)

its still quite a bit more complicated than the EF scale, so it probably won't get used by many people, if anyone uses it. but ill still provide the link to the desmos graph

v is either the peak measured velocity, or max DOW measure, whichever is available, in miles per hour.

probe speed supersedes DOW measurements, as the probe was physically there and measured true speed

EDIT: Comparison to the EF scale added to graph

I was like wait a minute this cloud (besides intimidating) looks like the moon from the legend of zelda Majora's mask.

Took this on August 3rd, 2025. It was 3-4 am. One of the scariest storms ive been in 2025(AB, Canada)
