A storm that will bring major disruptions of travel and daily activities to much of the nation will impact Washington, D.C., with rain, wet snow and a wintry mix Sunday night and Monday.
The storm is likely to bring at least 6 inches of snow with up to a foot possible. The local area has the potential for a heavy amount of snow and some ice if the storm turns more to the east, rather than to the north.
A south to north zone as little as 100 miles may bring a temperature difference of 50 degrees and a transition from rain and warmth to ice, snow and temperatures in the teens.
The snow may be difficult to shovel and plow due to its weight north and west of the city. There is also the potential for downed trees and power lines due to the weight of the snow and the possibility of ice.
Lengthy flight delays and many cancelations are expected well ahead of the storm, since it will move from west to east across the nation this weekend. The storm will hit portions of the Midwest with snow and ice Saturday into Sunday.
A bit of melting, wet snow and rain can fall on Sunday, ahead of the main storm.
The main storm is forecast to bring very heavy precipitation rates Sunday night and Monday. Snowfall rates can reach or surpass 2 inches per hour in some locations. Such intense snowfall can overwhelm shoveling and plowing operations, as well as strand motorists.
Motorists heading northward along I-95, I-66 and I-70 should expect very slippery conditions along much of the way with the potential for road closures in some locations.
More cold weather will follow the storm Tuesday and Wednesday.

Quote from the diary of William Colbert, a Methodist Circuit Rider up in Centre County: "A very cold morning. It was surprising to see so much snow on the ground at this season of the year. The limbs of the peach trees broke, and large limbs of the oaks broke down, and saplings bent across the road. It began to snow last night before we went to bed. I came out of my way by Lamb's to Phillip Antes."
