Love your site. The new Satellite feature is probably the best on the web. I use it to determine if the sky will be clear enough for astronomy.
One thing which may need some work is the radar. I think it understates the rain. This morning we had light rain which is noticeable when looking out the window. The radar showed the line of showers were well passed our area with no indication of precipitation near us.
I have also noticed that it will show lightening in areas before the rain shows up. That could be because the radar is delayed and the lightning indicator is almost instantaneous. We had lightening struck across the street and it showed up on your map within seconds. I zoomed in and found the placement of the lightning symbol was very accurate.
Thanks for your site. It is much better than the sites run by the Weather channel. They ruined the Weather underground site.
