An area of low pressure is approaching the D.C. area tonight from the southwest and should begin to affect parts of the region by Saturday morning. Precipitation is expected to start as a period of light snow across the majority of the region with light accumulations possible in the immediate D.C. area.
Precipitation should begin in the morning hours between 7am-10am across the region. Rain should begin to overspread the region by Noon in the D.C. Metro and points to the south and east. The system will exit the region by midnight Saturday.
Dependency on Area:
Big differences will be likely tomorrow in snow amounts in the D.C. area and places closer to the Mason-Dixon line such as northern Frederick County (MD), Carroll and Washington Counties as well. Areas farther north will have substantially more snowfall from this storm, and regions throughout Pennsylvania are expecting up to 8 inches of snow across much of the state.
Once again, the D.C. area itself isn't expected to see much of anything. A few snowflakes are possible at the onset of precipitation but snow should change to rain by the late morning hours in D.C. and points east. This appears like it will be another situation where even if it's snowing, accumulations on the roads won't be likely as temperatures should be at or above freezing and roadways should be above freezing.
Areas in higher elevations such as northern Loudoun, northern Montgomery and west into Frederick County, MD will have a better chance for light accumulations, even on the roadways.
We will be reporting live tomorrow morning on Newschannel 8 and will have a live blog going throughout the morning with the latest on where the snow is, where it's changing, and if there are any changes to the forecast. Be sure to stay tuned to ABC 7 News at 6pm and 11pm tonight for any recent changes to the forecast.
