There seems to be a delay in updating the GFS and NAM. Last update for GFS was 9 hours ago (ref 12Z), and for the NAM it was 10 hours ago (ref 12Z).

I live in the mountains - the Sierra Nevada in California. Surprisingly, one of the hardest pieces of weather information to obtain is the predicted snow level for upcoming winter storms. The NWS sometimes mentions this in a Winter Storm Watch or Warning, or their Forecast Discussion, but not always, and the information they give is rudimentary.

Windy has the option to show the freezing level, which is great, but it shows the freezing level for the altitude above the land, not the altitude above sea level. Showing the altitude above the land might work if the forecast models had, maybe, less than 1km resolution, but they don't. They average the elevation for a large area, so in the mountains it's very hard to determine what the freezing level above sea level, or the land, actually is.

In the Airgram I can see temperatures related to air pressure, and I can make the conversion to convert this to altitude, but that's a bit painstaking. It would be so much easier if we could just see the freezing level in elevation above sea level. We mountain dwellers would really appreciate that feature!

Still not updating. GFS up to 16 hours since the last update; NAM at 17 hours. What gives?

@beaverbanker - I noticed that too - great! Not in the app yet, but I hope it will be soon.

Thanks for the tip @stitch. I had to look up how to see the sounding forecast (just right-click on a spot). I just need to click on a nearby spot, but someplace where the model altitude is lower than the actual elevation I'm interested in. Then I can slide the little bar up and see the forecasted temp for the right elevation. Works great. It would be better if there was a more straightforward way to get this information, but that's still helpful.

@idefix37 - Thanks for the clarification.

@petra-pik - Still waiting for the next update of the app with the ICON global model. Any word on when the app update will be available?

@korina Any word on when you might get the U.S weather warnings fixed?

Why aren't weather warnings displayed for the U.S.? They used to be there, but now they're not. I only see them for offshore areas, not land.

It should have updated 4 hours ago. Is there a problem?

I live in the mountains (the Sierra Nevada in California), and currently there is no easy way in Windy to determine the snow level for an upcoming storm - a very important piece of information!

What would really help is to see the freezing altitude above sea level. I gather that the ECMWF doesn’t provide this - only the freezing altitude above the terrain, which is usually quite inaccurate in the mountains due to the ECMWF’s relatively coarse resolution. (For example, while the actual elevation for Yosemite Valley is 3970 feet, the ECMWF uses a model elevation of 7229 feet!)

However, the GFS does apparently provide the freezing altitude above sea level. I know this because the Ventusky app shows the freezing altitude above sea level for the GFS and HRRR models. The Ventusky app is pretty crappy overall, but it does provide this one useful piece of information that Windy does not. If they can do it you can do it! Please add this feature to Windy, and make the best weather app and website in the world even better!

And while you’re at it, please see if some other models provide the freezing altitude above sea level. Maybe the NAM?

Thanks so much!
