Cloud cover provides some good fishing opportunities for northern pike.  These fish will take advantage of an easy meal when they can get it and there are plenty of fish that are more active in the shallows when it is cloudy.  With the lower light conditions, the flashy lures and bright colors still help the fish to find your lure.  The flashy lures don’t stand out as much without the sun, but having flash and color will help these sight feeders find your offering.
