We Have a Week of Wild Weather Ahead of Us

A kinky jet stream will bring a week of extreme weather to the United States, promising a grab-bag of atmospheric excitement that ranges from mountain snows and Plains tornadoes to the East Coast’s first decent heat wave of the season. The coming storm systems exemplify the feast-or-famine nature of springtime weather, especially as we get closer to the peak of tornado season at the beginning of June. You might either be begging the sky for a little water in your garden or sprinting for your basement as yet another tornado warning blares from your cell phone.

Most of the significant weather events we experience throughout the year are the result of the jet stream, a fast-moving river of air that generally makes itself at home around 30,000 feet above sea level. It doesn’t seem like winds roaring along six miles above our heads can make much of a difference on the ground, but winds that blow in the middle- and upper-levels of the atmosphere are the driving force behind just about every major weather feature.

Pivotal Weather

These upper-level patterns are the reason it’s going to get toasty along the East Coast this week. High temperatures in the 90s are likely as far north as New England as a ridge of high pressure builds in place. Ridges, or northerly kinks in the jet stream, are the reason heat waves can get so intense. Ridges foster subsidence, or sinking air that clears the sky of clouds and makes the air quite toasty. The buildup of air at the surface leads to the formation of a high-pressure center. The more intense the high-pressure, the more intense the heat wave. It’s neither uncommon nor unprecedented to see summer-like heat in May, but it’s still uncomfortable nonetheless. The heat will be accompanied by humidity on Thursday and Friday, so those high temperatures hovering around the 90°F mark will feel even warmer thanks to the heat index.

Ridges are resilient. They don’t like to budge once they form, and this often leads to unsettled weather along the outer periphery of high-pressure systems. Several troughs will dig south out of the Rocky Mountains this week and lead to multiple opportunities for severe weather and heavy rain in the Plains and Upper Midwest. Significant severe weather is possible on Tuesday in the area traditionally known as Tornado Alley—storms from western Texas through western Nebraska could produce some violent tornadoes on Tuesday afternoon. More severe thunderstorms are possible in the central United States toward the end of the week.

One the storms are finished tormenting the central Plains, they’ll continue raining as they travel around the edge of the heat dome over the East Coast. NOAA’s Weather Prediction Center expects that two to four inches of rain will fall across a swath of land from central Texas to Lake Superior, falling over areas that really don’t need rain these days. Rivers in the Midwest are still trying to recover from flooding rains earlier this month. Any additional heavy rainfall will make the situation worse. Precipitation at higher elevations in the Rocky Mountains will fall in the form of snow, with mountain peaks possibly seeing several feet of snow before the weather settles back down.

The lack of rain is making things worse in Florida, where the resilience of the ridge and prolonged summer-like heat will send Florida and Georgia deeper into drought. While the rest of the country has largely recovered from any sort of lasting drought, the extreme southeast hasn’t been so lucky.

Large sections of Florida were in a severe or extreme drought according to the U.S. Drought Monitor’s update on May 11. The dryness isn’t only affecting agriculture—it’s also allowing wildfires to quickly spread out of control.

A lightning strike at the beginning of April sparked the West Mims Fire, a blaze located right on the border between Florida and Georgia northwest of Jacksonville, Florida. Officials reported on May 15 that the fire had burned about 237 square miles of land—an area more than three times larger than Washington D.C.—and was only 18 percent contained. Crews likely won’t receive any natural help in fighting the fire until the weekend, when the stubborn weather pattern breaks and showers and thunderstorms are once again possible.

Divers Swim With What Could Be the Biggest Great White Shark Ever Filmed

New pictures and video taken by divers show what could possibly be the largest great white shark ever caught on camera, CNN Travel reports.

Deep Blue, a 50-plus-year-old great white first documented 20 years ago, was spotted off the coast of Hawaii recently in a rare close encounter. Divers were filming tiger sharks feeding on a sperm whale carcass south of Oahu when Deep Blue swam up and began scratching herself on their boat. They accompanied the shark in the water for the rest of the day, even getting close enough to touch her at times.

"She swam away escorted by two rough-toothed dolphins who danced around her over to one of my [...] shark research vessels and proceeded to use it as a scratching post, passing up feeding for another need," Ocean Ramsey, one of the divers, wrote in an Instagram post.

Deep Blue is roughly 20 feet long and weighs an estimated 2 tons—likely making her one of the largest great whites alive. (The record for biggest great white shark ever is often disputed, with some outlets listing an alleged 37-foot shark recorded in the 1930s as the record-holder.)

Deep Blue looks especially wide in these photos, leading some to suspect she's pregnant. Swimming so close to great whites is always dangerous, especially when they're feeding, but older, pregnant females tend to be more docile.

Though great white sharks are the largest predatory sharks in the ocean, sharks of Deep Blue's size are seldom seen, and they're filmed alive even less often, making this a remarkable occurrence.

The Psychology Behind Kids' L.O.L. Surprise! Doll Obsession

Isaac Larian, the founder and CEO of toymaker MGA Entertainment, is an insomniac. Fortunately for him, that inability to sleep forced him to get up out of bed one night—a move that ended up being worth $4 billion.

Larian’s company is the architect of L.O.L. Surprise!, a line of dolls with a clever conceit. The product, which retails for about $10 to $20, is encased in a ball-shaped plastic shell and buried under layers of packaging, forcing children to tear through a gauntlet of wrapping before they’re able to see it. The inspiration came on that highly profitable sleepless night, which Larian spent watching unboxing videos on YouTube. It resulted in the first toy made for a generation wired for delayed gratification.

The dolls first went on sale in test markets at select Target stores in late 2016. MGA shipped out 500,000 of them, all of which sold out within two months. A Cabbage Patch Kid-esque frenzy came the following year. By late 2018, L.O.L. Surprise! (the acronym stands for the fancifully redundant Little Outrageous Little) had moved 800 million units, accounted for seven of the top 10 toys sold in the U.S., and was named Toy of the Year by the Toy Association. Videos of kids and adults unboxing them garner millions of views on YouTube, which is precisely where Larian knew his marketing would be most effective.

The dolls themselves are nothing revolutionary. Once freed from their plastic prisons, they stare at their owner with doe-eyed expressions. Some “tinkle,” while others change color in water. They can be dressed in accessories found in the balls or paired with tiny pets (which also must be "unboxed"). Larger bundles, like last year’s $89.99 L.O.L. Bigger Surprise! capsule, feature a plethora of items, each individually wrapped. It took a writer from The New York Times 59 minutes to uncover everything inside.

This methodical excavation is what makes L.O.L. Surprise! so appealing to its pint-sized target audience. Though MGA was advised that kids wouldn’t want to buy something they couldn’t see, Larian and his executives had an instinctual understanding of what child development experts already knew: Kids like looking forward to things.

Dr. Rachel Barr, director of Georgetown University’s Early Learning Project, told The Atlantic that unboxing videos tickle the part of a child’s brain that enjoys anticipation. By age 4 or 5, they have a concept of “the future,” or events that will unfold somewhere other than the present. However, Barr said, they’re also wary of being scared by an unforeseen outcome. In an unboxing video, they know the payoff will be positive and not, say, a live tarantula.

L.O.L. Surprise! is engineered to prolong that anticipatory joy, with kids peeling away wrapping like an onion for up to 20 minutes at a time. The effect is not entirely novel—baseball card collectors have been buying and unwrapping card packs without knowing exactly what’s inside for decades—but paired with social media, MGA was able to strike oil. The dolls now have 350 licensees making everything from bed sheets to apparel. Collectors—or their parents—can buy a $199.99 doll house. So-called “boy toys” are now lurking inside the wrappers, with one, the mohawk-sporting Punk Boi, causing a mild stir for being what MGA calls “anatomically correct.” His tiny plastic genital area facilitates a peeing function.

Whether L.O.L. Surprise! bucks conventional toy trends and continues its popularity beyond a handful of holiday seasons remains to be seen. Already, MGA is pushing alternative products like Poopsie Slime Surprise, a unicorn that can be fed glitter and poops a viscous green slime. An official unboxing video has been viewed 4.2 million times and counting.
