(WeatherBell) A potentially damaging ice storm is underway across the Mississippi and Tennessee valleys, slated to drop up a half-inch of ice while causing power outages and treacherous travel. The same storm system was bringing winter weather from the Panhandle of Texas to the Mid-Atlantic, with a slushy accumulation of snow and perhaps sleet all the way east to the nation’s capital. It marks the start of an active pattern that could bring multiple additional bouts of storminess to the Eastern Seaboard. Extreme cold straight from the Arctic to plunge south to Gulf of Mexico
Arctic blast over central U.S. set to worsen, expand Matthew Cappucci
(This story was updated on Tuesday) Subzero temperatures engulfed the majority of 10 states Tuesday morning, part of a bitter Arctic blast swallowing much the north-central United States. Temperatures some 20 to 40 degrees below average are set to dominate for more than a week, tied to the same polar vortex-induced weather pattern bringing stormy weather to the Northeast. After Sunday’s slush fest, another winter storm threatens D.C. by Wednesday night While the temperatures themselves may not break all-time records, the duration of this cold snap is unusual. Frigid conditions look to linger into at least mid-February, with temperatures dropping below zero in places such as Minneapolis, Chicago and Des Moines.
