Fish do not eat for 3 days after every front. They eat very rarely in the summer and sometimes in the winter, but they feed mostly in the spring unless a front passes through.
This is exactly why I quit fishing in July and start back in late February. Why bother if it's not CRAPPIE SEASON!!
I'm with Greg on this one, I don't think the front will hurt them much. Now that one coming Saturday night might curl their lip for a couple of hours!
