Please put your State in your profile so us old geezers can remember where you fish.
If the barometer didn't fall to low fishing is great after rains. The water is oxygenated and this makes fish frisky especially catfish. All fish feel better after a rain during HOT weather when oxygen levels are low. It just makes sense. Low oxygen levels lathargic fish... rain fixes that for a short time and they feel great.. I don't know if this is scientific or not. Just common sense after fishing before, during and after a rain.
Tight lines to ya!
