I bring a S.A.M.E weather radio (most of the time). Some of the best instructions I've read and try to practice is noting the wind direction and cloud formations (temps are in there too if I'm noting them) from this site. I am not always able to get it right but it helps to be able to anticipate weather changes. Agree with everyone's general take here that the weather is changeable and planning for just about anything is prudent.
