      @wade1201 If you don’t get an reply from someone living in Alaska, you can try to use the “Observation vs forecast” feature. It allows you to compare the temperature and wind forecast to the reported data by weather stations. Select Reported temperature of Wind temperature in the list of POIs. Choose a weather station near you location, if possible an official one (WMO or Airport weather station) Display “Observation vs forecast” [image: 1761309153759-ff7611b1-de5b-4c86-8437-9c9b558eba3f.jpeg] .

      @wade1201 Hi, in general, it is more advantageous to use regional models, which capture terrain features in greater detail - for Alaska, for example, HRRR‑AK or NAM‑AK (both operated by NOAA). In contrast, global models have coarser resolution and therefore tend to average out and “smooth” the terrain, but they offer forecasts over a longer time period. You can get an idea of how accurate each model is by comparing its output with actual measurements from a weather station (for example, here). Have a nice day, Jari

      Table in https://community.windy.com/topic/3340/when-and-how-often-are-the-weather-data-updated has some errors. E.g. GFS 0.25° Runtime (aka. Reference Time on Windy UI) is not 00:15, 06:15, 12:15, 18:15, it is 00:00, 06:00, 12:00, 18:00 UTC instead. Grib files of GFS 0.25° model are disseminated on NOAA site only about 3h35m after each runtime. About availability of models on Windy, the best choice is to click the "i" control just above the model selection bar: it provides Last Update Time as well as Next Update Time on Windy server side for currently selected model.
