National Weather Service forecasters in the Seattle office have issued a Winter Weather Advisory to today that forewarns of new snow accumulations in the lowlands today.
Forecasters said another round of a wintry precipitation is possible Saturday night into Sunday.
A widespread cold rain will continue and, at times, mix with freezing rain or sleet.
The snow is expected to hit Tuesday around 6:00 p.m. with it tapering off around midnight.
Snow breaks out 4-6pm Wednesday. The freezing rain or drizzle will change to "occasional rain or drizzle" by Thursday morning as the temperature rises above 0 C. Snow will spread northeast across the region taking over the whole area during the afternoon.
Here in Washington, D.C., the transition from snow over to sleet and freezing rain is most likely after the 1 p.m. hour.
Icing is possible across the region, but areas south of I-88 have the greatest risk. Most areas may receive a few centimetres of snow and ice pellets before the transition to freezing rain.
Expect snow covered roads and risky travel conditions from 10pm tonight through at least 7am Wednesday. This will create a messy start for many counties and likely several school delays.
Drier conditions expected for Thursday and Friday before rain and warmth returns for the upcoming weekend!
