Discussion

Accumulating snow is on the way for the weekend in the DC metro region. Low pressure will pull out of the southern US on Saturday and head towards the Tennessee Valley before ultimately winding up near the Outer Banks region of North Carolina by late Sunday. Snow will break out early Saturday in the central Mississippi Valley and then advance eastward during the mid-day to the Ohio Valley and then to the Mid-Atlantic during the PM hours. Snow will have difficulty reaching the ground at first in the DC metro region due to the very dry (and cold) air expected in the low-levels of the atmosphere, but should come down quite nicely by later in the day and again tomorrow night. On Sunday, as low pressure heads towards the North Carolina coastline, snow will continue for awhile in the metro region and then gradually wind down from northwest-to-southeast. Preliminary snowfall estimates for the DC metro region are 3-6 inches from this weekend event with the higher amounts in that range to the west and south of the District and the lesser amounts to the north and east.
