Looks like https://www.pwsweather.com/obs/RADILLY.html
is displaying data ... and hasn't missed a beat. I also turned on logging, which I hadn't fiddled with much. (Interesting stuff.) Didn't seem to need a restart.
Paul, I came across WeatherObs when I worked my way through the list. Appreciate the notes. I've heard of CWOP for some time, but never really dug into it, partly because my anemometer siting is not great. (Though what it observes tracks well with another PWS nearby.)
Given what I've seen since 1 January, I think I may just abandon Weather Underground. It's sort of back today, but I've noticed it's really sluggish to load. From the plot above it certainly looks like something came off the rails
on the 4th.
Cheers, and Thanks!
