The Northwest Flow Snowfall Discussion Group

An Extension of the Mid-Atlantic Collaborative Science, Technology, and Applied Research (CSTAR) Group

The Northwest Flow Snowfall Discussion Group was first created following the Fall 2005 CSTAR Regional Workshop held in Raleigh, NC. The group was designed as a "spin-off" of the regional CSTAR group with its primary focus being the specific regional forecast problem of northwest flow snowfall in the Appalachian Mountains. 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. The purpose of this Web page is to provide a central location to access all information that is directly relevant to the group.
