Moscow sees some of the most brutal winters of any world capital, but even locals weren't prepared for the most recent winter storm to batter the city. As Newsweek reports, a record-breaking 17 inches of snow buried Moscow within 24 hours.

Roughly 7 inches of snow fell just on Saturday, February 3, and the deluge continued through the following Sunday. The accumulation has already been dubbed the "snowfall of the century," and officials expect up to 3 additional inches to cover the ground over the next three days.

The sudden blizzard has brought life to a stand-still in the metropolis of 12 million. The mayor is warning motorists to stay off the roads as around 15,000 snowplows clear the snow. About 2000 trees have been toppled by the storm, injuring at least five people and killing one.

Even as the worst of the weather winds down, over 40,000 people in Moscow and the surrounding regions are without power. Meanwhile, traveling in and out of the city has become close to impossible: Around 100 flights are grounded at the local airport indefinitely and at least 10 have been canceled all together.

The historic snowfall hasn't stopped many of Moscow's tougher residents from venturing outside. Check out photos from the event below.

Denver is About to Experience Summer and Winter Temperatures Within 24 Hours

In a story tailor-made for exhaustive Weather Channel coverage, Denver, Colorado is about to experience one of the more bizarre weather shifts in recent memory. After an expected Tuesday high of 80°F, residents can anticipate a dramatic shift down to 32°F by midday Wednesday, with an initial half-inch of snow accumulation increasing to up to 7 inches by Wednesday night.

Put another way: Citizens who need to make sure they hydrate in the warm temperatures Tuesday will have to bring out the parkas the following day.

The Denver Post reports that the warm air coming ahead of the cold can result in a clash of air masses, prompting areas of low pressure that can create forceful and damaging weather conditions. The storm could bring winds of up to 60 miles per hour and possibly even cause power outages. Snow accumulation should dissipate by the weekend, when temperatures are expected to climb back into the 60s.

The high temperature record for April 9 in Denver is 81°F, set in 1977.

What Is a Bomb Cyclone?

The phrase bomb cyclone has re-entered the news this week as parts of the central U.S. face severe weather. Mountain and Midwestern states, including Colorado, Nebraska, Wyoming, and South Dakota, all fall in the path of a winter storm expected to deliver tornadoes, hail, heavy snow, flooding, and hurricane-force winds on Wednesday, March 13 into Thursday. It seems appropriate for a storm that strong to have bomb in its name, but the word actually refers to a meteorological phenomenon and not the cyclone's explosive intensity.

According to The Denver Post, the bomb in bomb cyclone stands for bombogenesis. Bombogenesis occurs when a non-tropical storm experiences at least a 24 millibar (the unit used to measure barometric pressure) drop within 24 hours. Low pressure makes for intense storms, so a bomb cyclone is a system that's built up a significant amount strength in a short length of time.

This type of storm usually depends on the ocean or another large body of water for its power. During the winter, the relatively warm air coming off the ocean and the cold air above land can collide to create a sharp drop in atmospheric pressure. Also known as a winter hurricane, this effect has produced some of the worst snowstorms to ever hit the U.S.

The fact that this latest bomb cyclone has formed nowhere near the coast makes it even more remarkable. Rather, a warm, subtropical air mass and a cold, Arctic air mass crossed paths, creating the perfect conditions for a rare bombogenesis over the Rockies and Great Plains states.

Central U.S. residents in the bomb cyclone's path have taken great precautions ahead of the storm. Over 1000 flights have been canceled for Wednesday and schools throughout Colorado have closed.
