Add NDFS NOAA model to list of models in Windy?

@idefix37 , I have sent email to NOAA asking this question. I do not know offhand which specific model that web site shows - in general, i have observed a few times (since I use both Windy-NAM and NOAA web site) that it is different than NAM.
I will let u know as soon as I get a response. Thanks!

As per someone from NOAA, (he is not part of dept that owns that web site), the web site uses the model at link above. Its called National Digital Forecast Database.

OK NDFD is not a model but an ensemble of models reviewed by meteorologists. Some additional information

Thank u for clarifying. This probably explains why it is relatively more accurate than NAM.
One question: Even if it is human involved and ensemble of models, do they store the 'output' data in such a way that it can be parsed by Windy? Presumably, NWS web site must be parsing the same output data to show on their web site?

NDFD data seem available as GRIB files, but I don’t know whether Windy team is willing to add these data. -
@idefix37 - this makes sense.
Windy team - can u pls respond when u get the chance? hoping it is as simple as adding a new URL for NDFD data. I can help u beta test it.
I know NWS web site (based on NDFD data) is popular among outdoor enthusiasts - mountaineering and sea kayaking.

@blahdi Is this NDFS so good? Which website uses it.
-
@ivo - its really good, specifically in the mountains or areas surrounded by mountains (e.g in the puget sound (its a bay) as well since it is in the convergence zone due to mountains).. For cities (without much impact of mountains), many sources should work..
NDFD is used by National Weather Service - US govt official weather site - if u see banner above, it says NWS and NOAA below it.
https://www.wrh.noaa.gov/forecast/wxtables/index.php?wfo=sewGFS is really bad for mountains or mountain affected terrains -
NAM is acceptable, but NDFS is much better than NAM.
You can search for a posts by a renowned weather scientist called "cliffmass" from Pacific Northwest. He has blogs on major problems with US govt published models. Unfortunately, the models do not publish their historic accuracy numbers for different terrains, and hence get away with inaccuracies. There was startup which compared the accuracies of different models for cities - and they reported one of the apps as more reliable. But, afaik, there hasn't been such a accuracy study done for mountains and water.

The site you mentioned, says:
"This Interface only works for Western Region National Weather Service Offices."Is it available only for NorthWest USA?

It looks like the Web site URL is different for different regions (local weather), but all of them are linked if u start at https://www.weather.gov/.
