As a nerd but not a weather nerd, I've been using wunderground since the first I ever knew of it (~2000). I did not think the redesign was a step backwards, but then I'm sure there are things that are of interest to wx foamers that I wasn't seeing.
Wunderground still absolutely thrashes the other major weather websites. I haven't ventured there in a couple years but I know the last time I visited weather.com it was so fugly, clickbaity, ad-riddled and just generally awful that I would rather navigate warez filesharing/download sites.
FWIW Stormpulse's website appears that it wouldn't show me any information until I "Signed in with LinkedIn" - I understand running a business and selling data, but, fuck that noise always and forever.
