Denver CO
Forecasts in this market are scored at Denver, Denver International Airport (KDEN), against the climate day for that airport, and against the NWS point forecast for the same grid. The airport is the official observation site for the market’s primary city. It is not every climate in the television market. TV station grading is coming soon. For now, the scoreboard grades the National Weather Service and the weather models.
No Denver ranking yet
A rank needs 90 days on which every station that has started, and the NWS baseline, all published a day-1 high that can be checked against a final observation. TV station grading is coming soon. For now, the scoreboard grades the National Weather Service and the weather models.

NWS baseline at Denver, Denver International Airport
This is the reference, not a contestant. Error here is the government point forecast against the climate day, on every day both exist. It is not limited to the days used in the station comparison.
Latest forecast archived Sep 27, 2026, 4:44 PM CT.
No overlapping days yet. A baseline error needs a forecast captured before the cutoff and a final observation for that same date. Forecasts point at the future; observations point at days already closed.
Official observations
Climate day at KDEN: midnight to midnight, local standard time. The low on this table is that day’s minimum, which is not always the overnight low a television graphic means. Why that choice is explicit.
