    • Please at least change the ECMWF summary text

      The Windy overview of ECMWF says:

      ECMWF 9km
      Very accurate model provided by the 
      European Centre for Medium-Range Weather
       Forecasts. Clear winner compared to other 
      forecast models.
      

      That may be true in some categories. For snow (levels and new) it is horrifically false, at least at altitude (mountains or not.)

      The following is a typical example:

      We live at 7050 ft on high plains in Colorado Springs. Just finished a two day round trip to Monte Vista, CO (7500 ft high plains) and nearby NWRs via La Veta Pass.

      There was no snow on the ground at any time (except maybe an inch in some shaded north facing slope spots at the top of the pass.)

      ECMWF thought we were seeing a foot or more of snow almost everywhere we went, and no less than a half inch except from ~ Pueblo to Walsenburg. (Ground modeled-reality and forecast)

      In our region, ICON is far more accurate for snow, both existing depth and new snow.

      SUGGESTIONS:

      • Correct the above summary text
      • Consider support for different models for different data streams.

      Thbanks!

    • Background Map: please enable major highways at all scales, for context visualization

      In some parts of the world, there are few obvious geologic features to provide context in the background map.

      Right now for example, I'm wanting to see the big weather picture in SW USA. It would GREATLY help if I could see the major (interstate) highways at least, if not one or two additional highway road layers.

      WIthout that, we only see OSM roads when zoomed all the way in to a local place.

      I would LOVE to see more zoom levels with OSM, at least as an option! (maybe OSM-enabled-layer as an option?)

      Thanks!

    • RE: Hurricane Beryl Made Landfall Nearby Matagorda,TX

      Has anyone else noted just how awful some of the models are, for hurricane forecasts?

      I had great interest in Beryl, as a family member lives on the Yucatan peninsula. Three models available: NHC-At, UKM, ECMWF

      In general, NHC-At has been pretty good, ECMWF unrealistically low, and UKM truly crazy-low.

      On Wed as Beryl approached Jamaica, I noted that just after a forecast update the discrepancy became rather extreme. Current wind speed was ~140mph. The noon forecast, only a few hours later, was literally a drop to half that in the UKM model, and a bit less extreme in ECMWF. Even 3 hours before noon, with wind speed increasing, the UKM forecast only increased to 80mph.

      The result: only the NHC-At model gave me any sense that it could produce a believable forecast.

      Why are the other two models used at all for this purpose?

    • RE: Suggested variable or variation on embedded forecast

      @Ondřej-Šutera Is there a place for feature suggestions?

      The reason for this thread is that it would be wonderful to have snow forecast in the embed forecast during cold months 🤠

    • Observation upload limits?

      Is there a limit to how many (time stamped) observations can be uploaded in a single API call? I don't see a reason why it would fail, but the docs don't say one way or another.

      I'm planning to write a catch-up function for weewx similar to what is available for other wx online databases :)

      @Ondřej-Šutera can I do layers in the forecast?

    • RE: Temp isoline in embedded Windy?

      @Ondřej-Šutera my real question is about the embed URL interface, and how to enable temp isoline.

      As you see above, I was told that isolines are not supported even in the API. Clearly they are.

      Do you know if temp isoline is, or may be, supported in embed URL's?

    • RE: Suggested variable or variation on embedded forecast

      @Ondřej-Šutera at 7000 ft in Colorado, there is very little relationship between predicted precipitation and predicted snowfall.

    • RE: API key unstable, maybe that explains station instability?

      I just confirmed the hard way. Both guesses are correct.

      When you click "show key",a new key is generated, and the existing key is no longer valid.
