The modernized end-to-end forecast process for quantitative precipitation information : hydrometeorological requirements, scientific issues, and service concepts

The purpose of this QPI concept document is to specify an operational framework which efficiently and effectively couples advanced meteorological and hydrological prediction on the shortthrough long-ranges. The terms short-, medium-, and long-range correspond to the following time spans: 0-3 days; 4-14 days, and 15 days or longer, respectively. This plan was developed in coordination with, and approved by, all NWS components and will be reviewed triennially by the HIWG to ensure the proposed forecast process continues to reflect and most efficiently meet the needs ofNWS forecasters, partners, and customers.
