A Winter Weather Advisory and Hazardous Weather Outlook by the National Weather Service (NWS) remain in effect for parts of Maryland and Northern Virginia, with the greatest concern focused on northern Montgomery County and areas farther north.
According to the NWS, the primary threat zone includes Frederick, Washington, Howard, and Carroll counties, as well as northwest Montgomery County, where wintry precipitation is more likely. Precipitation is expected to begin between 12–2 p.m. Friday and taper off around midnight.
The Winter Weather Advisory remains in effect from noon through midnight Friday for portions of central, north-central, and northern Maryland and northern Virginia. Forecasters are calling for mixed precipitation, including freezing rain and sleet. Ice accumulations are expected to range from a trace up to one-tenth of an inch, with locally higher amounts possible closer to the Pennsylvania border. Sleet accumulations are forecast to remain under half an inch.
The NWS warns that slippery road conditions are likely, especially during the Friday evening commute. Freezing rain and sleet are expected to overspread the region during the afternoon and continue into the evening hours. While temperatures are forecast to rise above freezing from south to north later in the evening, allowing some areas to change over to rain, other locations may hover near the freezing mark through the night. Light drizzle or freezing drizzle could linger into the overnight hours as precipitation exits to the northeast.
A Hazardous Weather Outlook has also been issued for central and southeastern Montgomery County, Washington, D.C., Prince George’s County, and parts of Northern Virginia, noting that accumulating ice and sleet in northeastern Maryland could still create slick travel conditions today and tonight.
Drivers are urged to slow down and use caution while traveling, particularly in northern portions of the county. Residents can check the latest road conditions by calling 511.
