Probabilistic QPF

Probabilistic QPF Experiment

Liquid Precipitation Amount Potential

Experimental - Leave Feedback

The purpose of these experimental probabilistic liquid precipitation products is to provide customers and partners a range of liquid precipitation possibilities, in complement to existing NWS deterministic liquid precipitation graphics, to better communicate forecast uncertainties during PQPF weather events.

Liquid Precipitation Totals by Location

These tables show the liquid precipitation forecast for individual locations. The tables provide the same information as the maps on this web page, just shown in a different way. All of these values are valid for the same time period as depicted on the graphics.
