Precipitation Forecast Products Based on NCEP GEFS Reforecasts, Version2
This page presents experimental precipitation forecasts, including deterministic and probabilistic forecast information produced with a rank-analog technique similar to the one described in Hamill and Whitaker (2006). It also presents graphical forecast products similar to ECMWF's Extreme Forecast Index. More detailed information on both is available here.
These forecasts will usually (but not always) be updated by 16 UTC each day. They likely will not be available as consistently as operational products from the National Weather Service. Also please note that this is an experimental forecast product, and is not an official forecast of NOAA or its National Weather Service. Precipitation units are mm (25.4 mm = 1 inch).
