General

The SNSQ parameter is available in real-time from several sources. For  WFOs, it is baselined within AWIPS D2D. Look in the volume browser under the “Winter” menu. The SNSQ parameter will be available for any deterministic models covering your forecast area. Online sources include the RAP-based SPC mesoanalysis for current analyses, or the St. Louis University CIPS page for GFS and NAM forecasts.
