Field notes
The page separates a model's run time from when ForecastTrail collected that run, and describes a trail of recorded values for each forecast day. Its review method compares the earliest recorded three-hour point peak with the NWS daily high, while noting that the two measures can use different day boundaries during daylight saving time.
