BTW...I have done the best I can thus far making the nws radar hi-rez resource hog work with limited hardware resources. Not sure if I can get it any better. It has to do with the transition animation. There is a lot of css, etc. that has to be processed with every transitional frame (slides).
Works great with old style nws radar... but there is no geo location available, so far as I know. Just regions, etc. That does not jive with the other nws resources needed for forecasts, etc. It is a conundrum of sorts.
That said, I have hard coded the location for mid atlantic radar using old school radar...

Pasadena (21122) is the default location, but you can enter any zip... Just keep in mind the radar never changes it's location. It is meant for mid atlantic users.
Though there is an option to view any nws hi rez location, independently, via the settings menu.
I have considered making a mobile version that excludes the radar from the emulation timeline while still allowing users to view a nws hi-rez geo location directly from the emulator menu.
I use this version as an app on my phone and it works good.
