A double whammy of snow and bitter cold is poised to descend over the D.C. area as an arctic front barges through late Saturday night into Sunday morning.
A winter weather advisory is in effect for snow, which could drop up to 2 inches or so in the Beltway region and a bit more toward Annapolis and Baltimore, perhaps falling heavily for a time predawn Sunday. The snow will be followed by the coldest air of the season Sunday into Monday, with wind chills dipping into the single digits Sunday night. Temperatures will then not surpass freezing until Tuesday.
