A major winter storm sliding up the northeast coast is predicted to cause blizzard conditions in New York City and Boston later today and dump up to seven inches of snow on Washington DC today. Clarke County, however, is expected to see only 1 – 2 inches from the storm.
As of yesterday, four to five inches of snow had fallen over several hours in Bowling Green, Ky., according to the National Weather Service. Louisville had about an inch of snow providing it with the first white Christmas there since 2002.
Airlines are already canceling flights ahead of the storm and are urging travelers to re-schedule flights using airline websites. Most airlines are waiving normal re-scheduling fees. Travelers who are able to reach Washington-area airports today will face the possibility of extended delays due flight cancellations across the US that are being caused by the storm.
“Try to get home early, and if you don’t have to travel, don’t go,” Virginia Governor Bob McDonnell told the Weather Channel.
As is always the case with “nor’easter” winter storm systems that impact the Mid-Atlantic region, the amount of snowfall our area will receive depends in large part on the storm track. Two low pressure systems just off the Mid-Atlantic coast, the first near Savannah, Georgia and the other near the North Carolina – Virginia border, will move northeast throughout the day. The counter-clockwise rotation of the storm systems will mix moist air from the Atlantic with cold air already in place to the west.
The result will be lots of snow to the east of our region with decreasing accumulations west of Washington DC.
The National Weather Service prediction for Berryville, Virginia as of 3:00 am EST is for a 90% chance of snow with a daytime high near 29 degrees with north wind between 8 and 15 mph. Total daytime snow accumulation of around an inch possible. Snow is expected to continue mainly before midnight with winds increasing to between 17 and 24 mph, with gusts as high as 39 mph. Additional new snow accumulation tonight of less than one inch possible.
