What shapes up for the spawn all depends on the weather right around that critical post-thaw period. The scenario I often see up north when the winter has been brutal is that everything just happens quicker when spring comes. Ideally, you'll see the stages of thaw, rapid spring warmth, and immediate bass spawning activity. Of course, this spawning activity happens within a shorter span of time than we're used to or than in the south where spawning behavior can happen for months. Ultimately, this shortens the pre-spawn period, which is a peak time to hook trophies, but not all is lost.
