Overcast days are THE best - more so summer/fall. Fish are generally spooky/nervous critters anyways so sunny bright days tend to have them 'on edge'. Add a little drizzle/rain and you can have your best days. Not just because fish tend to be more active , but because there are less anglers. For whatever reason, fisherman are afraid of rain - especially boat guys. I've hit major reservoirs/lakes on lousy weather days and seen no boats. Visit those same places on a nice sunny day and you'll see dozens of boats. A threat of thunder or lightning really keeps boats off the water (and bank beaters too)so those days can be good as well(just make sure the first time u hear thunder, get your ass back to the car)

Basically the theory is: the lousier the weather conditions, the better the fishing.
