Each forecast system’s record at every lead since February, with the ForecastEx prediction market beside it, is on the accuracy page.
Every scored day at a single station, with each tool’s error beside its forecast, is on that station’s own page. Reach one from a dot on the map.
NWS is the day/night forecast product; NBM is the National Blend of Models’ own daily max and min; GFS MOS is a single-model statistical product with no forecaster editing; LAMP is observation-updated hourly guidance with a 25-hour horizon. NBM is the guidance forecasters start from when editing the NWS grids, so those two are related, not independent. The ForecastEx line in the figure is the strike where the Yes price crosses 50¢, read from the last quote before local midnight. It is a price, so it is drawn in the figure and left out of the skill statistics. The record begins the day this site’s archive started; it grows by one day every day.
