I use resources on weather.gov for most of my personal forecasting. I know there are forecasts on there but I usually only need it for readings like pressure, humidity, and wind speed. Also I don't own a Doppler radar which is a very useful tool for figuring cloud density and shape. I do want to get a lightning detector though. That sounds neat.

As for your beans, if you got some spare cans and like pickled things, assuming they are green beans you could pickle them and they're pretty good. I like em that way at least.

Edit: I forgot to mention the accuracy of the forecasts. I have precipitation down pretty good. That's just pressure, wind direction, and cloud cover/type of cloud. Temperature is effectively magic where I live so it's hard to pin down. Still haven't figured out that one yet.
