wX is a free, no-ads, and open-source (GNU GPLv3) advanced weather application that is geared towards storm chasers, meteorologists, and weather enthusiasts. NWS (National Weather Service) data is optimized for mobile format and provided for divisions not normally covered together in the mobile space: SPC, WPC, NHC, OPC, etc. Level 3 and Level 2 Nexrad radar (single, dual, quad pane) are provided and displayed using the mobile variant of OpenGL. This weather app is not affiliated with NOAA or the National Weather Service.

If you only need current conditions and your local 7-day forecast then this app is probably more than you need although it will easily provide those two things as well. If you are looking for wasted screen real estate or fancy graphics this app is not for you. Given the depth of information covered there is a steep learning curve if you seek to use the program in its entirety, help information is available and touched on below. Common weather acronyms are used throughout so you should be familiar with those as well. Currently, United States locations are supported.

HELP is available from the main menu and by tapping on any text in the settings activities.
