Old Man Winter may have at least one more trick up his sleeve: A potential “bomb cyclone” storm could batter portions of the central and eastern U.S. this week and into the weekend, forecasters warn.”Confidence is growing for a significant storm that will bring wide-reaching impacts,” AccuWeather meteorologist Alex DaSilva said. That would include everything from rain and severe thunderstorms to high winds, snow and a rapid freeze-up across the eastern third of the nation, AccuWeather said.A bomb cyclone, which occurs through the process known as bombogenesis, is basically a winter hurricane. It “occurs when a mid-latitude cyclone rapidly intensifies,” or quickly drops in atmospheric pressure, marking the strengthening of the storm, according to the National Oceanic and Atmospheric Administration.Areas from eastern Oklahoma to western portions of Ohio, Kentucky and Tennessee, and even northern parts of Mississippi and Alabama, have a shot at up to a few inches of snow. Much heavier snow is likely farther to the east, according to AccuWeather senior meteorologist Alex Sosnowski.WHAT IS A BOMB CYCLONE? A winter hurricane, explained.Heavy snow is forecast across interior portions of the Northeast; as much as a foot is possible in some areas. “Not only is the Northeast looking at snow with this, but it could also be looking at some strong, gusty winds,” Weather.com meteorologist Domenica Davis said.This threat for high winds is highest along the immediate coast Saturday, as well as over the higher terrain of the Northeast, Weather.com said. At least some downed tree limbs and power outages are possible in these areas.WHAT IS THUNDERSNOW?
