Climate Forecast System (CFSv2) Ensemble Products
The output on this site is based on a 20-member ensemble generated from the four daily CFS control runs (00, 06, 12, & 18 UTC) over the past five days. Output is updated as each cycle is processed, and is typically available approximately 15 hours after cycle time (e.g. output which includes the latest 00 UTC run is available around 15 UTC).
Details on the CFS can be found at http://cfs.ncep.noaa.gov.
