DC Gearing Up for a Major Snowstorm

By Alex Sosnowski, Expert Senior Meteorologist

March 1,2014; 6:17PM,EST

A storm that will bring major disruptions of travel and daily activities to much of the nation will hit Washington, D.C., with heavy snow and a wintry mix Sunday night and Monday.
The storm is likely to bring up to a foot of snow with some locally higher amounts possible in the heaviest bands of snow.
That amount of snow may be difficult to shovel, especially with the snow being preceded by a layer of ice.
Lengthy flight delays and many cancelations are expected during and well ahead of the storm, since it will move from west to east across the nation this weekend.

One or two rain showers will occur Sunday afternoon, ahead of the main storm.
The main storm could 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.

More cold weather will follow the storm Tuesday and Wednesday.

Harrisburg Faces Major Travel-Disrupting Snow

By Alex Sosnowski, Expert Senior Meteorologist

March 1,2014; 6:15PM,EST

A storm that will bring major disruptions of travel and daily activities to much of the nation will hit Harrisburg, Pa., with substantial snow late Sunday through Monday.
Sleet will initially mix with the snow, but the majority of the event will be snow that will accumulate around 6 inches. There is the potential for up to a foot of snow near the Maryland border.
The snow and sleet will start Sunday afternoon.
Lengthy flight delays and many cancellations are expected well ahead of and during the storm, since it will move from west to east across the nation this weekend and impact major hubs.

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. That is especially true south of Harrisburg. Such intense snowfall can overwhelm shoveling and plowing operations, as well as strand motorists.
