I obviously really like Weather Timeline, as evidenced by my multitple posts about it.
It does have radar maps. Rainfall, Clouds, and temperature.
It's also got all the bars and charts that one would usually expect.
I second Arcus https://play.google.com/store/apps/details?id=com.arcusweather.darksky&hl=en
For a pure current radar display, I like Raindar https://play.google.com/store/apps/details?id=com.ghvandoorn.Raindar&hl=en
wow that is pricey but it sounds pretty spot on for that. also it's nearly at 5 stars with over 2K reviews. that's pretty damn high.
