RAP or Rapid Refresh offers:
An operational NOAA/ NCEP hourly updating operational weather prediction system covering North America comprised primarily of:
- A numerical forecast model
- An analysis/assimilation system to initialize that model.
These hour to hour updates can help us see weather models updated faster, more accurately, and provide valuable information for severe weather warnings.
