The National Weather Service at Baltimore/Washington continues a Blizzard Warning effective from 3 p.m. Friday afternoon through 6 a.m. Sunday morning for Baltimore, Annapolis, and Washington, D.C.
Low pressure will track across the southern states and then transfer over to a coastal low that will intensify off the North Carolina/Virginia border on Saturday. Cold high pressure to the north will ensure that most of the precipitation falls as snow. Snowfall amounts in this storm may range from 15 to 25 inches with isolated amounts around 30 inches. The combination of heavy snow and strong winds gusting over 50 miles per hour at times will result in power outages and treacherous driving conditions. Snow showers or light snow will begin to fall across the area by late Friday afternoon, and then become heavier during the evening hours. Winds from the northeast will become gusty, causing blowing and drifting snow. The heaviest snow and strongest winds will occur from about midnight on Friday until midnight on Saturday, with snow showers lingering in some areas into early Sunday morning. There may be a period of sleet for a few hours early on Saturday, or even a brief lull in the storm, but sleet will change back to heavy snow during the afternoon hours.
Closer to the Atlantic beaches, milder air will enable accumulating snow to change over to a period of rain or mixed precipitation and then back to accumulating snow for several hours at the end of the storm. Additionally, the beach resorts will be pounded with heavy surf, wind gusts over 50 miles per hour, and flooding due to high tides. A storm surge of up to five feet is possible.
