A link to comparative categorical 6-h QPF verification scores was added. The QPF products included in the scoring are from the (experimental) HRMOS QPF model together with other operational model and manually QPF products in categorical form. The scores are for the 2008-09 cool season and the 2009 warm season. Corresponding scores for the 2007-08 cool season are available at http://www.mdl.nws.noaa.gov/~qpf/ for NWS users.

Created public site at http://weather.gov/mdl/hrqpf/. A private website created in November 2008, which is available to selected NWS members, is being retained because it contains information not available at this public site.

Switched to an upgraded cool season system. Upgrades include new regression equations and probability thresholds, extension of the forecast projections up to 192 hours, and additional QPF predictands [i.e., a 12-h valid period for both the probability of ≥ 0.01" (POP) and the continuous precipitation product].
