Q: Recognizing bad weather and reacting

[ahlangle]

After spending several days fishing Big Lake last week, a few of my fishing weaknesses became evident to me, particularly in the question of weather.
How do you recognize a storm (vs just some rain) and its path, size, and distance?
Some of these are obvious and some take a closer understanding, but if my fancy electronics were to go out, I'd like to know when to haul arse and in what direction.
Thanks.
