NCEP Vision: First Choice – First Alert – Preferred Partner2
HPC’s Vision & Mission
Mission statement: to provide 1) forecast, guidance, and analysis products and services in support of the daily forecasting activities of the NWS and its customers, and 2) tailored weather support to other government agencies in emergency and special situations.
Vision statement:to be recognized by the NWS field offices and other forecast groups as a center of excellence for:
– facilitating collaboration
– heavy precipitation forecasting
– winter weather forecasting
– medium-range forecasting
– real-time numerical model diagnostics & interpretation
– surface analysis

HPC: a resource to field forecasters, other partners, and
customers
• starting point
• second opinion
• focusing mechanism
• unifying influence
• emergency backup

Major Needs
More accurate quantitative precipitation estimation Denser, more timely and accurate snowfall
observations More accurate numerical model forecasts, especially
for precipitation Better tools for forecasting convective precipitation More advanced forecaster tools for using ensemble
model output Greater use of precipitation forecaster input into
probabilistic river forecast models Additional forecasters to produce forecasts for
Alaska, Puerto Rico, Hawaii, Guam, and other OCONUS locations
NCEP Vision: First Choice – First Alert – Preferred Partner10
Initiatives in FY2009
Probabilistic QPF– Provides a probability distribution for precipitation
– Provides likelihood of various precipitation thresholds
– Provides indication of confidence
QPF at 6-h intervals at days 4-5
