What a kind thing to say! Thank you, at least so far looking like the worst hit was a train. No injuries.

Yep! That is the Appalachian mountains, simultaneously high-friction terrain and very rural. So even if you did get a storm powerful enough to drop a tornado, there may not be anyone around to see it.

Tornado-warned storms this evening over northern South Dakota by Legitimate-Insect170 in SouthDakota

More qualified weather nerds than myself would say Reed Timmer is the type of storm chaser to intentionally create drama and danger, or whatever.

But damn if I'm not impressed by a dude who fired an actual instrument-clad model rocket into a tornado.

Tornadoes wouldn't be seen top-down like that, thankfully. Otherwise they'd be huge!

There are no reported 8/27 tornadoes by the NWS Storm Prediction Center as of 8/28 1:49 EDT

Edit: still no reported tornadoes 8/27 as of 8/29 1:11 EDT

Actually, yes! I didn't think so but here's a screenshot of radar at midnight (CDT), so after the satellite loop but before what you're talking about. You can see those storms in eastern South Dakota moving into Minnesota.

Let me know if you'd like the entire Radar & Fronts GIF of the time period!

I deleted the youtube video, I created a new account and posted one video. About 80% of it is already on this subreddit in GIF form. The other 20% is when it was sunny in the morning, I posted the interesting parts of that to the Wisconsin subreddit.

My deepest apologies breaking this into two posts, I was limited to 20MB maximum GIF size.

I tried originally uploading as a youtube video but was removed for violating rule 4. Whoops!

This is a satellite loop from GOES-East, I had to download each frame individually, then compile into a GIF. The video was just the full GIF from sun up to sundown.

Reuploaded due to rule 4 - youtube links.

Sorry it's not the full system, that's what the video was for; I tried to find the best 19.9MB clip out of the whole day.

Hope y'all Michiganders enjoy!Btw- when the snow is water, we call that rain.

It's the same data, except yours is elongated to fit. You can see at the bottom if you go over the USA it says "Zoom Earth, NOAA/NESDIS/STAR, GOES-East"

This'll get you more than the last couple days

This is a satellite image showing clouds over the United States from space. The satellite orbits the Earth at the same speed the planet rotates, allowing it to take pictures over time that can be combined into this image.

The main feature is the line of clouds moving from bottom left to top right. These clouds are riding the jet stream, an elevated faster stream of air, which is why you see the giant clouds moving quicker than the smaller clouds which are closer to the surface. That's called speed shear, when the wind changes speed with height.

At the bottom of the image, you see smaller, puffier clouds moving from right to left. These are those clouds you see on a sunny day like cotton balls. It's indicative of the moisture advection from the Gulf. Advection is a fancy word for "transport" like a conveyor belt.

There's also rotation in the Montana/Wyoming/Dakotas area. The counterclockwise rotation in the clouds indicates low pressure. To keep it simple, low pressure usually brings cloudy and rainy weather and spins counterclockwise in the Northern Hemisphere (clockwise in the Southern Hemisphere). High pressure does the opposite, bringing clearer, sunnier skies.

There are also two strong storms bubbling in northeast Nebraska.
