Used to love Wunderground many years ago, not a big fan now...but, I have been using it on my phone recently as the local TV station I liked dropped support for a weather app that I really liked.
They had some very curious weirdness over the weekend, like when they predicted snowfall rates of 2" per hour for 8 hours but said that total snowfall for the day would be 5".
What?!??!
I guess that snowfall amount ended up being pretty accurate for Sunday, but they need to get the hourly and daily forecasts in sync.
