We currently don't have an easy way to integrate those stations. Here is one way that customers have used.
We do have a large network of PWS stations available.
Also note that for forecasts, whether you use WU, Aeris (our weather provider), or other services they won't actually be using a particular station but taking latitude and longitude in conjunction with radar/satellite data to predict. We use specific stations for observed data, but not for forecasts.
This explains how we predict if a schedule should be skipped or not.
Incorporating other weather services is definitely on our road map.
Hope this helps.
