The grid type “Comparison” (requires Abobe® Flash®) allows a visual overlay of QPF and QPE images. Areas that are gray indicate where the QPF-QPE differences were less than 0.25 inches or areas where no precipitation occurred. Areas that appear in green indicate where the QPF was too wet (QPF-QPE ≥ 0.25 inches), and areas in red highlight areas where the QPF was too dry (QPE-QPF ≥ 0.25 inches). The verification image is a grid created from subtracting QPE from QPF valid for the same time period. All images are identified by the ending date of the 24-hour period. The daily 24-hour verification period runs from 12:00 UTC to 12:00 UTC (4 AM to 4 AM during PST or 5 AM to 5 AM during PDT).
