The primary focus of the Northwest Flow Snowfall (NWFS) Discussion Group is exploring the forecast problem of northwest flow snowfall in the Appalachian Mountains. An example winter event is shown to the right with the observed snow accumulation and the participating NWS offices.
Numerous NWS forecast offices are affected by this winter weather phenomenon, and have taken an active role in the discussion group including Greenville-Spartanburg, SC (GSP), Morristown, TN (MRX), Blacksburg, VA (RNK), Jackson, KY (JKL), Charleston, WV (RLX), and Sterling, VA (LWX). In addition to these NWS offices, North Carolina State University, Appalachian State University, the University of North Carolina at Asheville (UNCA), the University of North Carolina at Chapel Hill (UNC), and the University of North Carolina at Charlotte (UNCC) are active participants from the academic realm. The group meets periodically throughout the year by way of telephone conference to discuss recent/upcoming northwest flow snowfall events, research updates, local modeling efforts, and other notable developments pertinent to the northwest flow snowfall phenomenon.
Much more information on the project is available in a Bulletin of the American Meteorological Society article – A Collaborative Approach to Study Northwest Flow Snow in the Southern Appalachians. Look for more updates on the NWFS project this cool season on CIMMSE.
