I've been playing with the Windy app (Android) for a few months now and am really looking forward to trying it for chasing. You can view pressure, dews, CAPE, radar (with lightning from Blitzortung), skewT, and soundings from your current location. There's also the option to view data through different layers of the atmosphere, from the surface to 150 mb. You can also view model data from the NAM, GFS, and even some ECMWF. Anyone else use it for chasing?
