Two separate storms will impact the region this weekend. The first arrives tonight and the second arrives on Sunday night.
The National Weather Service has issued a Winter Storm Watch for central and southern Maryland, the District of Columbia, northern Virginia, the upper Eastern Shore and Delaware for Sunday afternoon through Monday morning.
NBC 4 Meteorologist Chuck Bell reports we could see 2 to 5 inches of accumulation.
Everything will start as rain this evening, but during the overnight hours there will be a mix with, and perhaps even a changeover to, sleet.
By sunrise Sunday morning there may even be a 1" to 2" accumulation of sleet in Metro DC.
During the day on Sunday, temperatures should climb just high enough to change most of the precipitation back over to a rain / sleet mix.
Then, in comes the second storm. It will be moving up the coast Sunday night into Monday morning, and with a lot more cold air to deal with, it is more likely to be a snow producer.
There is a WINTER STORM WATCH for areas along and EAST of I-95 from Sunday afternoon through Monday morning. Since there is still a great deal of uncertainty with this second storm you will need to tune in frequently for updates, but here is the way it looks right now.
Several inches of snow are possible in the DC Metro area. Since the storm will be a little farther off the coast than usual, heavier snow may fall EAST of the DC area into Southern Maryland and on the Eastern Shore.
You may already see the Virginia Department of Transportation gearing up for slick, slippery roadways. Salt trucks are already out there pre-treating the roads. Nearly 200 trucks will be out by 11pm Saturday to treat roads, bridges, overpasses and ramps, as well as residential streets.
