Another Arctic Blast Freezes The Eastern U.S.

UPDATED By WeatherBug Meteorologist, Seth Carrier
After yesterday`s winter storm dropped several inches of snow on the Mid-Atlantic, frigid air from Canada has taken control of the central and eastern U.S. this morning.
Substantial snow fell yesterday as a small but potent winter storm raced across the Mid-Atlantic. Two to 8 inches coated the region, including 3 inches at Reagan National Airport in Washington, 2 inches in Alexandria, Va., and 4.5 inches in Wilmington, Del.
However, the counterpart to this snow is a frigid batch of high pressure dropping into the central and eastern U.S. While this means dry weather, temperatures have plummeted this morning due to clear skies, fresh snowpack and calm wind. Low temperatures will range from the minus-20s in northern New England to the single digits in the Mid-Atlantic and upper 20s into the Southeast.
A few record lows will even be challenged this morning in the East. Detroit has the best chance to break a record low, dropping to near 2 degrees above zero. Its record is 5 degrees set in 1912. Pittsburgh will drop near 0 degrees, coming just shy of its record of minus-1 degree set in 1943. Philadelphia will do the same, dropping to near 8 degrees while its record for this date is 7 degrees. A few other cities along Interstate 95, including Washington, D.C., and New York City will come within 7 or 8 degrees of record lows this morning.
A bit of a westerly breeze crossing the eastern Great Lakes will produce dangerous wind chills as well. Wind Chill Advisories have been posted in western New York and northern Pennsylvania where wind chills will drop as low as minus-15 degrees.
Any melted snow or ice and any wet spots on roadways farther south in the Mid-Atlantic and Carolinas could become treacherous as temperatures drop far below freezing. In addition, the cold weather will dive all the way into the Southeast, threatening the early part of the growing season. In fact, Freeze Warnings are in effect in northern and central Georgia, including Atlanta. Lows will drop into the upper 20s for several hours, damaging tender spring vegetation already planted.
The Arctic high will then retreat north back into Canada, setting the stage for a moderating temperature trend into the middle of the week.
