Rare phenomenon sweeps rural Maryland leaving locals terrified Armageddon is about to strike
A scary-looking 'doomsday' cloud rolled through Maryland last week, leaving locals terrified a world-ending storm was brewing.
The ominous white tornado-shaped cloud funneled down from massive dark billows and swept through a field in Thurmont, Maryland, on May 5, according to AccuWeather.
Local meteorologist Justin Berk shared videos from the area after forecasting heavy rain, damaging winds and thunderstorms throughout the day.
Terrified commenters expressed their fears over the video and speculated on what exactly the formation could be.
'That would've terrified me lol,' one person said. 'New fear unlocked,' said a second person. 'Wow if I saw that I'd be heading the other way,' added a third.
'Looks like a [tornado] trying to form,' another person said. 'Super cool and almost scary!' said a fifth.
However, the strange formation was actually a scud vacuum, which is non-threatening and slow-moving fog bank that has very different characteristics to a tornado.
'Using the word "vacuum" isn't a good way to describe scud clouds, because there's really no sucking going on,' said Cowboy State Daily meteorologist Don Day.
Scud clouds, also known as pannus clouds, are a type of low-lying fractus cloud that form beneath storm clouds.
They are known as 'accessory clouds' that occur below the main base cloud, according to the International Cloud Atlas.
'When you get into a thunderstorm situation, there's a lot going on at the base of those clouds,' Day said.
'You can get these little vortices that will spin off the base of a cloud and take a piece of cloud with it. Scud clouds are basically pieces that have broken off larger clouds.'
AccuWeather claimed scuds often get called 'scary-looking clouds' by meteorologists because viewers report them as tornadoes or funnel clouds.
However, while scud clouds can appear like they are moving as they rise, they do not rotate like a tornado or funnel cloud, rendering them harmless, according to KBTX.
'You're going to get scud in a thunderstorm environment or a really strong cold front when there's a lot of turbulence and moisture in the air,' Day said.
'You can have scud in an environment where there could be or may have been a tornado, but it doesn't mean there's a tornado coming.'

Ping, ping ping. Here's what it's like to drive into a big hailstorm in the name of science
Wind roared against the SUV's windows as its tires sloshed through water dumped onto the road by the downpour. A horizon-wide funnel cloud loomed out the window, several miles away. Then came the loud metallic pings on the roof. First one, then another. Then it was too fast to count and too loud to hear much of anything else. Hailstones were pelting down, and the car was driving toward them. 'How big are they?' meteorology professor Kelly Lombardo asked from the passenger seat. 'Probably no more than a nickel or dime, but they're just flowing at 50 mph,' said fellow researcher Matthew Kumjian as he steered through the flooded road. Lombardo and Kumjian are part of a team of about 60 researchers chasing hail across the Great Plains to better forecast an underappreciated hazard that causes about $10 billion a year in damage in the U.S. The researchers brought along three Associated Press journalists to observe the first-of-its kind project called ICECHIP, including trips into the heart of the storms in fortified vehicles like the one driven by Kumjian. The payoff is data that could improve hail forecasts. Knowing what's going on inside a storm is crucial to knowing what's going to happen to people in its path, meteorologists said. 'We have a really tough time forecasting hail size,' said Northern Illinois University meteorology professor Victor Gensini, one of the project leaders. 'All scientific experiments start with data gathering, and without that data we don't know what we're missing. And so that's what this project is all about.' Inside a hail storm On this afternoon, Lombardo and Kumjian, Penn State University professors who are married to each other, were negotiating rapid weather changes while collecting their data. Minutes before the hail started, the couple were launching three-foot wide weather balloons designed to give scientists a glimpse of what's happening in the leading edge of the storm. A tornado in the distance was slowly getting closer. Soon cell phones blared tornado alarms, and a nearby town's storm sirens roared to life. The couple jumped in the car and drove into a part of the storm where they could collect hail after it fell, the same stretch of flooded road where they encountered the 50 mph winds. A wind-meter protruding from the black SUV's front captured data that was displayed on Lombardo's laptop. 'This is up there in terms of severity of winds and intensity of precipitation,' Kumjian told an AP reporter after finding a safe place to pull over. Elsewhere in the storm, Joshua Soderholm of the Australian Bureau of Meteorology launched weather balloons carrying devices built to mimic golf ball-sized hail and outfitted with microphones and special sensors. One flew up 8.9 miles at 163 mph. 'It's free floating. It does whatever the storm wants it to do,' Soderholm said. 'This is the only way you could actually get a measurement of what a hail storm might be doing.'' Researchers also deploy special funnels that capture pristine hail, crushers that measure how strong the ice balls are and other high-tech machinery, including radar and drones. Keeping storm chasers safe The teams also use a variety of gear and practices to stay coordinated and safe. At morning briefings, they review forecasts to plan the safest way to reach the storms producing the most hail. At their destination, teams set up at varying distances to the storms, with three fortified vehicles driving into the heart of the weather. Each vehicle has radar screens in the front seats showing brilliant reds, oranges and yellows of the storm they chase. Gensini is in a command vehicle that tracks and deploys the teams based on weather in real time. At times he has to rein in some enthusiastic chasers. So Northern Illinois meteorology student Katie Wargowsky radios a team deep inside a storm to find safety. Twice. The 21-year-old Wargowsky described how becoming a storm chaser began as an effort to overcome weather anxiety so intense she would dry heave while taking shelter in her family's basement. But confronting her fear helped her develop a deep curiosity that led her to chase tornadoes with her father. 'You get a rush of adrenaline,' she said. 'You really start to notice the little things around you, and your head just feels kind of light. Your natural survival instincts tell you, you need to take shelter, and you need hide from it. But you just know that it's about to be some good research, and you are changing the world one storm at a time.' The three fortified vehicles are equipped with special metal mesh to protect their windshields. But it's not foolproof. The SUV driven by the Penn State researchers lost its windshield in May to sideways-blowing hail that flew under the mesh just 15 minutes into their first storm chase. Another one of the fortified vehicles, called the Husky Hail Hunter, was pelted by three-and-half-inch hail during a trip into a storm with an AP photographer aboard. 'We're getting some new dents,' said Tony Illenden, the Northern Illinois student at the wheel. 'This is insane.' When he stepped out to collect a hailstone — wearing a helmet to protect his head — one slammed into his right hand, causing it to swell in what Gensini called the first hail injury of the season. A few days later Illenden, said his hand felt fine. Natural beauty and better roofing For the storm chasers, the payoff isn't just the data. It's also the natural beauty. Illenden's team, for example, collected a three-inch (81 millimeter) hailstone that looked like a rose. That same night a double rainbow emerged. After the storm passed, several vans descended on a Walmart parking lot to crush hailstones with special machines that measured how much force was needed to shatter them. 'In hailstones we have layers. So we start off with an embryo, and then you've got different growth layers,' said Central Michigan University scientist John Allen. Since May 18, while logging more than 5,700 miles, the team has collected, measured, crushed, weighed and sliced hailstones as big as 5.5 inches, about the size of a DVD. The study funded in part by $11 million from the National Science Foundation, which took eight years to plan, is already paying off even before researchers have had a chance to thoroughly review the data, scientists said. Gensini said one early data trend he's noticing is that 'the largest hail that we found is not where we thought it would be in terms of the Doppler radar.″ And that's an issue because Doppler radar is the only tool forecasters have been using across the country to say where the big dangerous stones should be falling, he said. Given the federal cuts to science, particularly related to the climate, Gensini said this is likely the first and last time a hail project like this can be done, at least for several years. Scientists from the insurance industry, which is helping fund the study, are testing new types of roof shingles that so far seem to resist hail better, said Ian Giammanco, a meteorologist at the Insurance Institute For Business and Home Safety. "One of our goals is to replicate all of this back at our lab so we can really understand how durable our roofing materials are to all the different flavors of hail,' he said. ___ The Associated Press' climate and environmental coverage receives financial support from multiple private foundations.

Mapped: Where three-day thunderstorm warning will impact UK this weekend
A three-day-long thunderstorm is set to sweep across the UK this weekend as temperatures are forecast to hit 30 degrees. Rising temperatures this week, brought on by a plume of humid air from Iberia, increases the risk of thunderstorms across the country. Yellow thunderstorm warnings are set to last from Thursday through to Saturday, with the Met Office warning of potential travel disruptions. On Thursday Wales and south-west England, including Devon, Somerset and parts of Cornwall, will be affected by a yellow weather warning until 7pm. Northern Ireland is also forecast to experience heavy rain until 9pm. The forecaster warned there was 'a good chance driving conditions will be affected by spray, standing water and/or hail, leading to longer journey times by car and bus', with delays to train services possible. Short-term power loss and other services are also likely. On Friday at 3pm until Saturday at 6am, London and the South East covering parts of Cambridgeshire, Norfolk, as well as Surrey, Kent and East Sussex, have been given a yellow weather warning. Heavy rain and thunderstorms are also expected in parts of Wales and south-west England with a yellow warning between 6am and midnight on Friday. On Saturday, in addition to the thunderstorm warning in London and the South East, the forecaster issued a yellow warning until 6pm spreading from sout-west England and Wales all the way across the West Midlands, Yorkshire and south-west Scotland. Some western areas could see 20 to 40mm of rainfall over just a few hours, with intense downpours moving northeasterly with lightning on Thursday. Meanwhile, the second band of thunderstorms is set to move in again from the South West on Friday and will cause intense rainfall into the early hours of Saturday. Most of England, Wales and parts of Scotland could see 30 to 50mm of rain in a few hours. The forecaster revealed there will be a chance of delayed public transport and power cuts, while homes and businesses could flood quickly with damage to buildings from floodwater, lightning strikes, hail and strong winds. But the spell of warm weather, which could see parts of England reach 30C, has also triggered a heat-health alert by the UK Health Security Agency (UKHSA) between 9pm on Thursday and 8am on Sunday. Under UKHSA and the Met Office 's weather-health alerting system, a yellow alert means that there could be an increased use of health care services by vulnerable populations, leading to an increase in risk to health for individuals over the age of 65 and those with pre-existing health conditions, including respiratory and cardiovascular diseases. Dr Agostinho Sousa, head of extreme events and health protection at UKHSA, said that even moderate heat can result in serious health outcomes, especially for older adults, making it important for people to take precautions in the sun. 'The forecasted high temperatures are expected to be short-lived but could primarily impact those over the age of 65 or those with pre-existing health conditions,' he said. 'If you have friends, family or neighbours who are more vulnerable, it is important to check in on them and ensure they are aware of the forecasts and are following the necessary advice.'' Met Office deputy chief meteorologist Mike Silverstone added: 'As temperatures rise this week, it is possible heatwave thresholds could be reached in some parts of the UK, particularly the north-west Midlands, north-west England and north-east Wales, however it is very dependent on cloud cover later this week, so it is not a certainty. 'This warm spell will feel different to the fine weather we experienced in May as the humidity will be much higher, making it feel more uncomfortable. Additionally, while in May the nights were still fairly cool, overnight temperatures this week are forecast to remain fairly warm, which can disrupt people's sleep.'
