Reforecast-Based Precipitation Products on the Web at NOAA ESRL/PSD

NOAA's Earth System Research Lab, Physical Sciences Division has pioneered the production and use of reforecast-based products for weather applications.  In this talk we review the suite of reforecast-based products that ESRL/PSD hosts on its web site, including analog and distribution fitting products for probabilistic and deterministic precipitation amount, extreme forecast indices, and more.  These products, as demonstrated in several recent journal articles, are highly skillful and reliable.  In part because of their success, the NWS is embracing the regular generation of reforecasts, so the PSD products provide a glimpse at the sort of technologies that will become more mainstream in the next few years.
