It’s back: Another potential derecho storm could hit U.S. Northeast

July 26, 2012WEATHERA derecho, the kind of storm that knocked out power to millions in Washington last month, may accompany bad weather forecast for New York City and the rest of the Northeast tomorrow, the U.S. Storm Prediction Center said. There’s a moderate chance the rare windstorm will develop in an area from Indiana to Massachusetts, the center said on its website. The region is also at risk for severe thunderstorms, hail and possible tornadoes after noon, according to John Hart, a meteorologist at the agency’s Norman, Oklahoma, offices. “The environment is going to be favorable for considerably severe weather right across the area even if we don’t get a derecho,” Hart said by telephone. Last month, a derecho knocked out power to at least 4.3 million people from New Jersey to North Carolina as it unleashed winds of as much as 91 miles (146 kilometers) per hour, as powerful as a Category 1 hurricane. Twenty-four deaths were linked to the storm and its aftermath, according to the Associated Press. A derecho is defined as an event that has wind gusts of at least 58 mph and leaves a swath of damage for 240 miles, according to the storm center’s website. A storm that swept from Chicago to Kentucky yesterday also seems to have met the definition of a derecho, Hart said. Yesterday’s storm wasn’t as intense as the one that struck the mid-Atlantic, including Washington, on June 29, he said. Hart said derechos are hard to predict because they require that a number of atmospheric elements come together. “There is no way to have high confidence in such a forecast,” Hart said. “We decided the risk of that scenario happening was high enough that we would highlight it.” The area from western Ohio to southern New England will probably be in the path of severe storms tomorrow afternoon, Hart said. New York, Pittsburgh, Cleveland and Cincinnati all have a 45 percent chance of severe thunderstorms, high winds and hail. –Bloomberg

    Derecho hits the Chicago area downing trees and power lines; 183,000 lose power

    Originally just a thunderstorm complex (MCS) that had developed along a northwest to southeast frontal boundary across portions of Minnesota and South Dakota late last night, the storms moved into a more favorable atmosphere for strengthening and began to produce wind damage across southwestern Wisconsin earlier this morning. After travelling approximately 280 miles (from southwestern Wisconsin to northeast Illinois to northern Indiana) with winds between 60 and 80 mph, this thunderstorm complex was safely classified as a small derecho.

    Rare “Super” Derecho Slams South Jersey (And 4 Other States)

    Glenn explains why the storm that slammed New Jersey this past weekend was both extremely rare and extremely unpredictable. Derecho’s are pretty rare in this area to begin with; a “Super” Derecho is almost unheard of. And, they are even harder to forecast than tornadoes because they are so rare.

    So many Derecho storms this year alone, but usually they only have one every other year!! This should tell you somethings wrong with our climate!

    Hi Alvin, wasn’t sure how to get hold of you other than on comments, but this isn’t really a comment; here is a link to a story I thought you might be interested in if you don’t already have it. http://www.nytimes.com/2012/07/26/us/rise-in-weather-extremes-threatens-infrastructure.html?_r=1

    Our area, North Central Ohio, is in the crosshairs of this storm. I’m hoping that I’m home by then. I would hate to miss a good storm. Besides, we have a basement here. Also praying that the power stays on. Would hate to have no power in this heat.

    Just heard on The Weather Channel that there were tornados in Canada in Saskatewan. (It’s an extention of tornado alley.) Some damage but no injuries.
