| Quantitative
Precipitation Forecast, or QPF, is a prediction of precipitation amounts
over an area. In this case, the area is that of the LMRFC. QPF is
created for six hour increments for the next 72 hour periods at 12z
and 00z and 54 hours at 18z and 06z. This is routinly done three times
a day (00z, 12z, and 18z), but can be at 06z if the weather dictates
. The resultant LMRFC QPF is then used as an input into the hydrologic
model and river forecasts are issued based on QPF. |
