All, I was subject to the dismal fishing conditions last Friday night. Spent 4+ cold hours tied up to a bridge waiting for the fish to bite....only to pull up every minnow I originally put in the water.
Come to find out, there was a high pressure weather pattern. I thought that an approximate wait time of 48hrs since the cold front blew would help settle things out....I guess not.
Couple of questions I have so that I can avoid a skunked outing in the future.

Is this a solid fishing rule that a high pressure system will shut the bite down?

How "high" is a high pressure system and at what point is it a definite no go?

Is the opposite true that a low pressure system is optimal for fishing?

Thanks for any and all input.
