An area of low pressure is expected to develop off the east coast tonight and into the day tomorrow as energy slides into the region from the west. Expect increasing clouds this afternoon ahead of this disturbance with highs in the lower 50s. Tonight, rain should begin to fall through the area just before midnight and eventually change to snow in the higher elevations through the early morning hours. Temperatures should fall and remain steady around the 40 degree mark for much of the region.
The coastal low will intensify on Saturday as it moves just east of D.C. As this happens, more cold air will move in behind this system and rain will begin to change to snow for much of the area west of D.C. Accumulations will be on the order of a dusting around the D.C. Metro, to 1-2 inches in the western suburbs, to 5 inches or more in the higher elevations. The best timing for the changeover from rain to snow in the immediate D.C. Metro will be around Noon, with the change occurring earlier in the western suburbs. Heavy rain will also be possible with this system, with up to an inch and a half possible along and east of D.C. Temperatures should hang in the 30s through the afternoon and precipitation should come to an end by the late afternoon and evening.
Sunday will feature clearing skies, breezy winds and chilly temperatures in the upper 40s. It will be a cold start for runners in the Marine Corps Marathon, with temperatures hovering around freezing and some breezy winds making it feel even colder.
