I like the Windy App, especially the winds at elevation. Pretty accurate.
If you don't like the layout, then you will hate Weather Underground. Sensory overload, full of annoying ads. If I join, will the ads go away? Also, WU is crowd-sourced, so any schmuck can post his personal weather station data. I'm not sure I can trust "Phil's Weather Station in Green Oaks Subdivision." I always seek out the nearest airport location.
I used to like WU because it showed cloud ceiling on the front page, but no more. Nor can I find winds aloft like Windy. WU has gone downhill in usefulness, IMO.
