Subject: Soliciting comments on PQPF graphics from May 1, 2018,
 through March 1, 2019

The National Centers for Environmental Prediction`s (NCEP)
Weather Prediction Center (WPC) is soliciting comments on the
Experimental Probabilistic Quantitative Precipitation Forecast
(PQPF) Graphics. The provision and use of PQPF information in
the forecast production process will provide users and partners
with a potential range of forecast accumulated precipitation, a
capability that is not currently possible with existing
deterministic QPF products issued by NWS Weather Forecast
Offices (WFO).

This information will allow for better communication of forecast
uncertainties and provide more effective impact-based decision
support services for communities sensitive to flood threats.
WPC, using direct input from WFOs via established collaboration
tools and protocols, will create and distribute the PQPF
guidance. WFOs will generate web graphics, depicting reasonable
least and most amounts possible as well as the most likely

By May 1, 2018, the experimental PQPF Graphics will be available
online at the following offices:

Miami, FL:
Miami, FL:
Boston, MA:

Wichita, KS:
Melbourne, FL:
Milwaukee, WI:
Detroit, MI:
Salt Lake City, UT:

page, can be found at the following link:

NWS will provide additional opportunity for review and comment
on the experimental product before any operational decision. If
you have questions or comments regarding the Experimental PQPF
Graphics, please contact:
