DC Area Forecast: Early Icing Areas, Then Driving, Cold Rain


* Winter Weather Advisory Montgomery, Howard, northern Fauquier and Loudoun until 1 p.m. | ice storm warning Until 10 p.m. in Frederick County, Maryland, and along and west of Interstate 81 | Closures and delays *

8:10 a.m. – Rain for most of the day around Washington, D.C.; freezing cold limited to north and west

Around the nearby DC area, it was raining desolately cold. Half an inch of rain has already fallen in many places, with another inch or more likely to fall today. It’s a snow lover’s worst nightmare: rain and 33 degrees in many places. But for motorists and pedestrians, the absence of ice is certainly welcome.

The winter weather advisory has ceased for the region and for Fairfax, Prince George, Prince William and Anne Arundel counties due to the lack of ice.

The icy problem remained confined to the north and northwest of the ring road, where temperatures hovered around 32 degrees. Even in these places, it’s not cold enough for ice to cling to sidewalks, although some slippery spots may form on elevated surfaces like decks, bridges, and overpasses — where caution is advised. We’ve also seen some reports of light glaze developing on trees in some of these areas.

As stated in our previous update (below), our primary concern is the large amount of ice and slick roads near and west of Highway 15, which roughly runs from Warrenton to Leesburg to Frederick. We haven’t seen widespread reports of dangerous travel in the area as it’s raining hard and the water is running off rather than sticking to the road. However, ice may develop, especially in untreated areas. If you head west on Interstate 81, ice buildup on trees and power lines can become a problem over time, potentially causing power outages.

Our next update will be after 9am

6.55am – worst conditions west of Frederick, Leesburg and Warrenton

Around the ring road and in the south and southeast, temperatures remained above freezing (33 to 35 degrees), with moderate rainfall and wet roads. Temperatures hover around freezing north and northwest of the Beltway and west of Fairfax County, where you’re likely to encounter some slippery places, especially on elevated surfaces: decks, bridges, overpasses, and ramps. Trees can also be painted with a light glaze.

The most dangerous conditions are mostly around and west of Highway 15, roughly from Warrenton to Leesburg to Frederick. Along and to the west in the area, road surfaces and temperatures were in the 30s and 32s in many cases. Use extreme caution when walking and driving in this area, especially on untreated surfaces.

In Virginia, road temperatures were freezing along Interstate 66 east of the Front Royal, along Route 50 near Paris Mountain, and along Route 15 south of the Potomac River. In Maryland, sidewalks were freezing along Interstate 70 near the Frederick-Washington County line.

5:50 am – Cold temperatures and icing mostly north and northwest of the Beltway

The Washington area has been seeing heavy rain, cold enough to freeze on some surfaces primarily north and northwest of the Beltway.

Inside the Beltway and to the south and east, it’s been raining for the most part, with temperatures usually around 33 or 34 degrees and the roads just wet. Still, be careful stepping outside, as wet surfaces can appear slippery.

North and west of the Beltway, in western Loudoun and Prince William counties, and in northern Fauquier counties, temperatures were near freezing. In these areas, be aware of icing, especially on untreated surfaces, bridges, ramps, and overpasses.

Severe, more widespread ice is expected in the mountains west of Loudoun and west of Frederick (Maryland), where temperatures will be 31 degrees or colder.Overnight, the National Weather Service Ice storm warning extendedprimarily along Interstate 81 and west, into Frederick County.

Temperatures should remain where they are now for the next two to three hours before starting to rise from the southeast to the northwest from mid-morning to mid-morning.
