@spencernb Yes, at Kanab, Utah, ECMWF model shows lower temperatures. HRRR is much better and Meteoblue for local forecast is probably the best (shown with Observation vs forecast feature with the reported temperature at weather station of Kanab Municipal Airport). Fortunately ECMWF is not so bad everywhere. Why does this model give so bad temps forecasts at your location? Difficult to say. The model altitude is 100m higher than the real altitude, it explains a part of the discrepancy. There are mountains near Kanab, so a model with higher resolution like HRRR gives better results. But in Windy, given the temperatures provided on the Utah map, the ECMWF looks lower overall and it's hard to explain.

@spencernb Hello, information about models is available in the menu under "About these data". But thank you for suggestion.
