(AP Photo/The Herald Bulletin, Don Knight) (Newser) – Move over, polar vortex: The Northeast is prepping for a major snowstorm—what could be Washington, DC's biggest in three years. A look at what the region faces today: Philadelphia: The Inquirer says a "bombogenesis" is coming this afternoon. What's that? "A rapidly intensifying storm." The city and surrounding areas, including parts of New Jersey and Delaware, are expecting 7 to 11 inches of snow. As almost everywhere else is reporting, "dangerous cold" is also expected. New York: Could see its biggest storm of the season so far, with 8 to 14 inches of snow expected, the New York Times reports. Temperatures are expected to drop into the single digits tonight; add in the wind and it'll feel like 10 below. The storm is expected to pass by tomorrow morning, though freezing temperatures won't break until ... Monday. Washington, DC: Is expecting the most snow in nearly three years, with an accumulation of 4 to 7 inches in the metro area by tonight, the Washington Post reports. Temperatures will fall, too, dropping to the single digits by tonight—and are expected to stay freezing until Friday. Federal government offices are closed due to weather today. Boston: The area is expecting 6 to 9 inches of snow, with more accumulating in areas south of the city. There's also a blizzard warning in effect south of the city and in areas including Cape Cod, Martha's Vineyard, and Nantucket, the Boston Globe reports. Snow is expected to end by 1pm tomorrow, but frigid temperatures will continue the rest of the week. Snow is also expected in the Midwest. And bad news for everyone: Many states are experiencing a propane shortage, meaning heating could be an issue. Eighteen states have declared energy emergencies in an effort to loosen restrictions and get propane across state lines more quickly, NBC News reports.
