I use weather.com, and also the app that came with my phone.
In Nashville, we also have a local weather site called Nashville Severe Weather (NSW) which is run by the hubs of one of my friends and a couple other men. It's my go-to, not just because it's a friend's thing, but because it's very informative and so much information is communicated in a very user-friendly way,. It's my fave. A lot of folks use it. It's won awards.
