From 60 Saturday to snow Sunday: D.C. area under winter weather advisory.
A coating to 2 inches is most probable with highest amounts north and west of the District.
Today at 11:54 a.m. EST
* Winter weather advisory from 1 a.m. to 4 p.m. Sunday (excluding Southern Maryland) *
The D.C. area has been enjoying a taste of spring, but in a heartbeat winter will roar back Saturday night into Sunday, with some wet snow expected.
A cold front crossing the area Saturday will bring much colder air that will ooze into the region by nightfall. Meanwhile, a zone of low pressure will form along the front, allowing precipitation to develop overnight Saturday through the first half of Sunday.
A mix of rain and snow will probably change to snow during the predawn hours Sunday with light accumulation possible through midday, especially in our colder areas north and west of downtown Washington. The National Weather Service has issued a winter weather advisory for the District and counties to the north and west, including Fairfax, Prince George’s and Montgomery, from 1 a.m. to 4 p.m. Sunday. The advisory does not include Southern Maryland.
“Plan on slippery road conditions,” the advisory states. “The heaviest accumulations will be on non-paved surfaces.”
We would anticipate the most hazardous conditions between about 5 and 9 a.m., when temperatures are lowest and snow is falling most steadily, especially in our colder areas north and west of downtown Washington.
