Have a look at Berry Weather. It dies not do what you want but it is a new app and the developpers are currently responsive to requests. If you can convince them, they might put it in. Fishing is very popular and that may just sway them.
The popularity of fishing and hunting are why I'm a little surprised there isn't an app out. I've been just pulling them up via the web browser but a stand alone app would be nice. Thanks to you both for responding.
