A tornado in northeastern Tennessee near La Follette produced a strong debris signature on Doppler radar imagery around 600PM EDT on Sunday. The tornadic storm occurred as part of an unusually strong severe weather outbreak taking place across the easternmost third of the country this afternoon.

A severe weather outbreak is ramping up over parts of the eastern United States this afternoon, with an area that doesn't typically see much severe weather bearing the brunt of today's action. The risk for EF-2 or stronger tornadoes is 1000 times higher than normal in some spots.

A large part of the eastern United States is on track to see two distinct and very dangerous severe weather events both today and tomorrow, with the worst outbreak expected to occur tomorrow over the Ohio Valley and Mid-Atlantic regions.

Tara Reid recently said in an interview that a sharknado really could happen. Contrary to all you sharknado truthers making fun of Reid, I agree with her assessment. The real question is to figure out where a sharknado is most likely to occur. Let's take a look at the science.

The makers of Reynolds Wrap are thrilled to announce the latest loony chapter in the long running battle against chemtrails, with residents of Shasta County, California DEMANDING that their county stop the federal government from spraying them with non-existent chemicals. L'horreur!

A tornado struck a campground in Cheriton, Virginia around 9:00 this morning, killing two campers and injuring 26 more as the storm swept through the area. A news helicopter flying over the Cherrystone Campground for WAVY shows dozens of trees torn down along with many tents destroyed and strewn about.

Twister is arguably the most popular weather movie ever made, and it sparked an interest in meteorology in both kids and adults alike. While the movie is incredibly entertaining, it's also on some pretty solid ground when it comes to the science. Just how much did the creators of Twister get right and wrong?

Over the past twelve years, we've seen tens of thousands of tornado warnings across the United States. Almost every major city east of the Rocky Mountains has seen a tornado warning at some point since 2002, and the resulting maps are pretty cool looking.

A meteorologist for a television station in Ohio Anthony Weinered himself on Twitter this morning when he sent out a shirtless selfie, only to delete it a few minutes later and then blame his wife for doing it on a dare.

Out of the comfort and into the fire went the central United States this week as the latest NotReallyAPolarVortex left in a hurry. Temperatures themselves are hot enough — topping 105°F in places — but as the old phrase goes, it's not the heat that gets you, it's the humidity. On days like today, the heat index is crucial.

The vast majority of Tweets are useless. Twitter feeds are an endless stream of #random and #unnecessary hashtags, shady shortened links, and poorly-made pictures hawking one's favorite political candidate (who probably sucks). And yet, we keep Tweeting. Why?

A system in the middle of the Atlantic Ocean has a high chance of developing into a tropical cyclone over the next few days as it moves west towards the Caribbean. If it develops into a tropical storm, its name will be Bertha.

It's killing season in Washington, and no monument is safe. After a climate scientist loses his funding and then his mind, a senator is in a fight for his life after the jilted whiz creates a device that controls the weather. This 2011 made-for-TV movie is...something, for sure, and I watched it so you don't have to.

The Weather Channel premiered a new show this afternoon called WXGeeks, which has all the potential to bring the network back to its weathery roots. Did it hit the mark? It's hard to tell — the show was over before it began.

Over the next few days, meteorologists will make a fuss about "record low maximum" temperatures being achieved in cities across the southeast. What does that term mean, anyway?

Super Typhoon Rammasun made landfall in southeastern China earlier on Friday with winds of 155 MPH, making the storm equivalent to that of a borderline category 5 hurricane in the Atlantic. Satellite and radar imagery coming from the storm are downright impressive, showing Rammasun's nearly-perfect structure.

Remember all the soccer fans who chewed out a New York TV station for preempting the World Cup final for a tornado? Here are a bunch of soap opera fans doing the same thing to NBC for covering the crash of Malaysia Airlines 17, which claimed 295 lives. It's not just the weather that brings out the worst in people.

While people along and east of the Rockies seem to have thunderstorms almost every other day this time of year, folks along the West Coast never see our level of exciting weather. Putting aside the ongoing drought, why doesn't the West Coast ever seem to see thunderstorms?

On its website yesterday, Fox News published a groundbreaking report that the cold temperatures accompanying this week's polar vortex might cause an uptick in heart attacks. Since, y'know, that bitter 70-degree weather is hell on the ol' ticker.

Slow-moving thunderstorms around Colorado Springs this afternoon dumped enormous amounts of rain over the region in a short period of time, leading to dangerous flash flooding across the area. One resident of the city took this incredible video of the water pounding a bridge with the fury of Niagara Falls.
