Discussion
The Arctic front at the leading edge of a widespread brutally cold air mass will slide into the eastern states on Sunday and its progression will slow down across the southeastern states. Energy will rotate through an upper-level trough to a position over the frontal boundary and low pressure will form in this area of convergence. That low pressure system will then push northeastward into an increasingly colder air mass, and it can produce several inches of snow in the DC-to-Philly-to-NYC corridor from tomorrow into tomorrow night.
Total snow accumulations in the DC metro region likely in the 3-6 inch range with isolated higher amounts… a starting time around mid-morning. The higher amounts in this range will be on the northwestern side of the metro region and the lower amounts on the southeastern side. Bitter cold air will follow the accumulating snow for the first half of next week and overnight temperatures will drop way down to the low-to-mid single digits.
