A winter storm is bringing a heap of snow to the Mid-Atlantic as much of the nation’s midsection shivers from near-record cold. An arctic blast will sweep into the East just as the winter storm departs. An arctic blast occurs when weather is pushed from the Arctic circle down to us, typically causing frigid temperatures.
Winter Storm Warnings and Winter Weather Advisories continue from western Tennessee to the Mid-Atlantic beaches, including Nashville, Tenn., Richmond, Va., Raleigh, N.C., Washington, D.C., and Atlantic City, N.J.
A bit of a westerly breeze crossing the eastern Great Lakes will produce dangerous wind chills overnight. Wind Chill Advisories have been posted in western New York and northern Pennsylvania where wind chills will drop to minus-15 degrees overnight.
Freeze Warnings have been posted for tonight in northern and central Georgia, including Atlanta. Lows will drop into the upper 20s for several hours, damaging tender spring vegetation already planted.
A few record lows will even be challenged tonight 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 to 0 degrees, coming just shy of its record Tuesday of minus-1 degree set in 1943.
Philadelphia will do the same, dropping to 8 degrees while its record for March 4 is 7 degrees. A few other cities along Interstate 95, including Washington and New York City will come within 7 or 8 degrees from records lows Tuesday.
The Arctic high will then retreat north back into Canada, setting the stage for a moderating trend into the middle week. Get the full weather details
