Greetings! This is my first post here. I have seen a lot of informative discussions about MADIS QC since getting involved in this fascinating world of CWOP, and I wanted to ask something that I haven't quite seen addressed in this forum elsewhere.

Like many PWSs, after my data was run for a couple of weeks, my Wind QC comes up as less than satisfactory:

But nobody around me seems to have good Wind QC, either...including my local airport (which is not a small or insignificant airport!):

https://weather.gladstonefamily.net/site/KROC

If my local airport fails MADIS Wind QC, then what hope is there for little old me? I noticed at the time of sending this, my reported data and KROC's reported data basically matched, while the "Analysis" for our two stations differed wildly. Might this be just a factor of lots of bad wind data around me (and around our airport, which I would think should be considered authoritative)?

Welcome to the forum.  The wind analysis has had issues for a while.  Take a look at https://www.wxforum.net/index.php?topic=39095.msg409212#msg409212 and https://www.wxforum.net/index.php?topic=41451.msg424730#msg424730

Yeah I never figured that one out - your major airport fails but you're great.  :roll:
