Nobody knows the answer to this. Fish are completely unpredictable. We think we understand a little about them, we want to understand, but we realy don't. Think back to your prior fishing experiences. I have been fishing in April after a viscous cold front where the air temp dropped 30 degrees and it was sleeting. The next day the fish were in 2 inches of water and we caught one every other cast it seemed.
Same lake a few years later in May on a Sunday: Fish were ON. It was one of those day were you catch so many fish it actually gets boring. The next day, with the same temp, same skies, same barometer, same everything, and you couldn't buy a bite.
The poster on the 1st page suggests that big fish feed during daylight hours and most big bass are caught at a certain time. On the other hand, a famous study tracking big bass in Texas found the exact opposite: "Hope also learned that big bass feed predominantly at night, 12 months a year. "Every fish over 7 pounds is a nocturnal feeder,” Hope said. “They may feed periodically during the day. But they do most of their feeding at night, usually in two-hour intervals. They feed for a while and then rest for a while.”

My point isn't to say somebody is wrong, or somebody is right. The point is that we don't understand these fish .0001% as much as we think we do. Go fishing when you have the time and don't worry about the things you can't control like the weather.
