Quantitative Precipitation Forecast, abbreviated QPF, is a forecast of the amount of liquid precipitation that will accumulate over a defined geographic area and time period. It is typically given for forecast horizons such as 6, 12, 24, 48, or 72 hours and reported in units of millimeters or inches.
QPF is produced by weather forecasting centers using numerical weather prediction models, ensemble forecasts, and data
The primary purpose of QPF is to inform decision making in areas such as flood forecasting, water
Limitations and uncertainties are intrinsic to QPF. Forecast skill declines with longer lead times and over
