I do use Accuweather - but I also have a permanent link to the online site with the frontal and jet stream maps. Accuweather needs to dump the videos and put those in.
Weather Underground had them, maybe still does, but trying to become more of a social site. Weatherbug did that, and instead of a forecast, all you got was pictures from social end that you didn't want.
If NOAA ever adds those in the form I like, I'll use that. I far prefer the weather discussions than pretty pictures.
