6 Surprising State Weather Records

Something that truly unites all Americans is the belief that their home town lays claim to some of the worst weather in the country. Residents of nearly every state often repeat the joke that if you don't like the weather there, just wait five minutes and it'll change. Most of our exciting weather is rather ordinary, if not short-lived, but some events really are so extreme that they wind up in the record books. Here are some states where the weather was anything but ordinary.

1. MAINE: A RECORD NUMBER OF TORNADOES

Maine is pretty close to the bottom of the list when you think of states that are prone to tornadoes. Just like every other state, though, Maine's rugged landscape isn't immune to torrents that can produce wicked damage. A powerful outbreak of thunderstorms on July 5, 2017, produced five separate tornadoes across Maine, setting a new record for the most tornadoes to ever touch down in one day in this northeastern state.

While this was a relatively bad day in Maine, it pales in comparison to the most tornadoes to ever touch down in one day. More than 200 tornadoes touched down on April 27, 2011, mainly across Mississippi and Alabama, in what became one of the worst tornado outbreaks in recorded history.

2. NEW HAMPSHIRE: THE TOP WINDS ON A MOUNTAINTOP

New Hampshire's Mount Washington is famous for the extreme weather that tests the resolve of hardy scientists who work at its peak. The observatory at the top of Mount Washington has seen some of the worst weather imaginable, including the strongest wind gust ever directly recorded in the United States. (This was the global record as well until 1996, when a wind gust hit 253 mph in Australia during Typhoon Olivia.)

Scientists measured a 231 mph wind gust on the afternoon of April 12, 1934, as a storm system roared its way across New England. The observatory's intense winds are attributable to the fact that it lies more than 6000 feet above sea level, exposing it to the powerful atmospheric winds that make intense storm systems possible.

3. TEXAS: THE RAINIEST DAY EVER

Hurricanes are a fearsome weather catastrophe, but weaker tropical cyclones—tropical depressions and tropical storms—can cause just as much damage through the sheer amount of water they can bring ashore. No one understands this more than the residents of the small town of Alvin, Texas, which set the record for the most rain ever recorded in a 24-hour period. A weather observer in Alvin measured 42 inches of rain between the mornings of July 25 and July 26, 1979, as Tropical Storm Claudette swirled ashore. Records show that there may have been even more rainfall in Alvin as the rain gauge began overflowing at one point.

4. ALABAMA: THE WETTEST MAJOR CITY

The Pacific Northwest has a deserved reputation when it comes to constant rainfall. Seattle, Washington, sees rain on more than 150 days each year, but when it does rain there, the precipitation is on the lighter side; it's often an annoying drizzle.

But if you want real rainfall in a cityscape, head down to Mobile, Alabama, which is the rainiest major city in the contiguous United States in terms of yearly average rainfall. This city on the northern Gulf Coast typically sees more than five feet of rain every year. There are plenty of places that see more rain annually; Maple Valley, Washington, for instance, gets more than seven feet of rain a year. On the other hand, only 22,000 people live there. For the biggest rainy impact on the largest number of people, Mobile—home to just under 200,000—takes the cake.

5. MISSOURI: THE COSTLIEST HAILSTORM IN HISTORY

A pang of fear strikes through the stomachs of every car- and homeowner when a barrage of hail begins falling from the sky. It doesn't take much hail to cause a lot of damage, and the damage gets exponentially worse as the hailstones tick up in size. Parts of central Missouri and Illinois saw the costliest hailstorm ever recorded [PDF] back in April 2001, when a supercell thunderstorm dropped hail up to the size of baseballs over a path more than 240 miles long.

The hail damaged hundreds of thousands of buildings, tens of thousands of vehicles, and even caused substantial damage to more than two dozen airplanes at the airport in St. Louis. Once the skies cleared and residents tallied the damage, they found that the storm caused more than $1.5 billion in insured losses.

6. COLORADO: THE BIGGEST ONE-DAY SNOWFALL ON RECORD

If you love the cold and just can't get enough snow in the winter, there are few places you want to be more than the Rocky Mountains. The bitter cold, constant stream of storms, and jagged terrain create the perfect conditions for gobs of snow to fall all at once. A weather reporting station at Silver Lake, Colorado, nestled in the mountains west of Boulder, caught the jackpot one day nearly a hundred years ago. The town recorded more than six feet of snow—75.8 inches, to be precise—in the 24-hour period between April 14 and April 15, 1921. That's some deep powder.

Britain Is in the Midst of a Rare ‘Wind Drought’

Generating renewable energy in Britain is a little less than a breeze these days: A “wind drought” is halting the country’s wind turbines.

This month’s wind energy output is down 40 percent from the same time last year, New Scientist reports. On average, about 15 percent of Britain’s electricity comes from wind power. Data starting from July 1 of this year put the monthly average closer to 6.9 percent. Last month, turbines were producing less than 2 percent of Britain’s electricity—the lowest output in two years.

That’s with even more wind turbines being installed over the course of the past year, New Scientist says. The data aren’t entirely surprising, though. The jet stream tends to make the UK’s weather drier and calmer during the summer and wetter and stormier during the winter. But the high pressure the jet stream has brought with it this year has been unusually prolonged, scientists say.

“It’s like a lid, it keeps everything still,” UK Met Office spokesperson Grahame Madge told New Scientist. “From the forecast looking out over the next couple of weeks, there doesn’t seem to be any significant change on the way.”

The wind drought shouldn’t cause too many problems in the short term. Electricity demand is low during the summer (very few British homes have air conditioning), and the country’s been able to compensate for the lack of wind by burning more natural gas. If the wind drought continues to persist, though, UK residents may begin to see an increase in utility fees. Natural gas prices have already risen with the increased demand.

“As we continue to transition to a low-carbon energy system, managing the intermittency of renewable power an important role in balancing supply and demand,” a National Grid spokesperson told New Scientist. “However, we have planned for these changes and [are] ready to play our part.”

The wind drought comes about eight years after British politicians vowed to reduce the UK's dependence on fossil fuels. Last year was the first year that electricity generated from low-carbon energy sources like solar power, wind power, and nuclear power outpaced high-carbon energy sources like coal and natural gas. This summer’s wind drought may make it difficult to improve on last year’s numbers.

Why Does the Sky Look Green Before a Tornado?

A common bit of folklore from tornado-prone parts of the U.S. says that when the skies start taking on an emerald hue, it's time to run inside. But why do tornadoes tend to spawn green skies in the first place? As SciShow's Michael Aranda explains, the answer has to do with the way water droplets reflect the colors of the light spectrum.

During the day, the sky is usually blue because the shorter, bluer end of the light spectrum bounces off air molecules better than than redder, longer-wavelength light. Conditions change during the sunset (and sunrise), when sunlight has to travel through more air, and when storms are forming, which means there are more water droplets around.

Tornadoes forming later in the day, around sunset, do a great job of reflecting the green part of the light spectrum that's usually hidden in a sunset because of the water droplets in the clouds, which bounce green light into our eyes. But that doesn't necessarily mean a twister is coming—it could just mean a lot of rain is in the forecast. Either way, heading inside is probably a good idea.

For the full details on how water and light conspire to turn the sky green before a storm, check out the SciShow video below.
