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 for NWS users.
