I am sure it has been posted before , but with all the new members that have joined maybe I can learn something here about barometer pressure . I was fishing last night and they was not biting as good as they should have been . It is going to storm today so I thought it could have been the barometer pressure building up . What I am wondering is does the barometer pressure build up or go down before a storm . Also do the fish bite better or worse before a storm . I know I could look all this up myself but I am interested in a catfishermans point of veiw not the news man or some others .
