The only thing I can think of with my vast knowledge is maybe current changes,

The north wind doesn't stir up enought bait fish to get them feeding.

Just a guess

Well when pressure starts to drop it triggers feeding. It isn't sure why, but theory has been that the fish anticipate several days of bad weather and feed for it. Once the pressure stabilizes, the fish should be back to normal. Pressure rising shuts them down too. Another theory is the pressure changes screws with thier swim bladder until they equal out...??

I've heard that wind doesn't even effect bait fish because they are strong enough to swim in what mild currents, if any, wind will produce. More importantly is the wind stirs plankton that baitfish feed on. This is what gathers them in the wind.

Why the north wind screws them up is beyond me. Like the saying, "wind from the east, fishing is the least." I'm sure that wind effects lakes differently in different parts of the country.

Doesn't a low pressure system rotate clockwise, and and a high pressure system counterclockwise?  It would seem to coincide with north/south wind fishing conditions.
