I know a couple of buddys have been with me on Green & I've told them it was getting ready to shut down when I saw the backend of the cloud line where a front was pushing through & it did. WE were catching good fish each time & when the cloud line passed we hardly got another bite the rest of the night when fishing until early am the next morning.I believe it messes it up worse than any other lake I fish. Could be wrong, but I absolutley believe in the barometric pressure in the case of a cold front causing a shut down after or a feeding frenzy before it passes through.
