A Wintry Kick-off

11:20 AM 1/1/14 (Winter Stormcast Team) Happy New Year wishes to all our readers! While we are starting off the year today with seasonable and dry conditions, a winter storm will impact the eastern U.S. late Thursday into Friday. Two separate disturbances will combine over the eastern half of the country, while high pressure to the north feeds cold air into the region. 

The latest precipitation projections (shown left) from NOAA show two regions of impact, with much of the central mid-Atlantic receiving less in possible snow or rain.




IMPACTS: For much of the Mid-Atlantic, precipitation will start as rain or a rain/snow mix. Precipitation is expected to changeover to snow Thursday evening into the overnight hours from north to south. 
  • Snowfall accumulation is likely for many areas at least from the Washington, D.C. area northward. 
  • The highest snowfall amounts should be across Pennsylvania and New Jersey, where significant accumulations will be possible. 
  • Farther south into the Baltimore/Washington, D.C. metro area, light to moderate snowfall accumulations will be possible. Areas farther to the south will likely see little accumulation before the storm ends later Friday morning.

TIMING: Precipitation should begin by late Thursday afternoon or early evening from southwest to northeast. 
  • The heaviest snowfall amounts will be Thursday night. Snow will clear out from west to east by late Friday morning. 
  • Strong northwest winds Friday morning will add to the hazardous travel conditions wherever snow accumulates.

Stay tuned for more updates and specific forecast amounts to be posted later today. (Forecaster Jason M. and the Winter Stormcast Team)
