Cold fronts are not fronts at all, they are the back side of a low pressure system. The term comes from the cold air in front of the high pressure system filling in the low pressure depression. The atmosphere is made up of varying degrees of moisture levels from near 0 to 100%. The higher levels of moisture in the atmosphere defuse sunlight. Clouds for example are a form of moisture that condense into rain droplets and clouds can only move into low pressure depression within the atmosphere, they are pushed away from high pressure areas .High pressure therefor has very low levels of moisture, humidity,little sunlight diffusion.
Since bass live in water the water pressure on the bass is minutely affected by barometric pressure, however the airborne environment is greatly affected by pressure changes. A falling barometer indicates lower atmospheric pressure is present and higher levels of moisture is coming to fill in the depression. Light becomes defused, airborne insects are pushed down onto the water surface and the entire food chain becomes very active taking advantage of the reduced light and activity. Bass that live in shallow water, where light intensity is a major factor in the predator prey relationship, become active feeding on baitfish that are feeding on insects etc. Bass that live in nearby deeper will move up to take advantage of the activity created by the low pressure system moving in.
Then the high pressure system begins to push out the low pressure system and in between the 2 systems is cold air or the cold front. The atmosphere clears dramtically, very little sunlight diffusion and wind pushed by higher pressures clears out the airborne insects. The deeper water bass retreat back to their nearby deeper water and the shallow water bass move under cover and wait for the high pressure to pass, the cold clear air to leave and their ecosystem to normalize. The deeper water bass simply return to their already normal environment and are less affected by barometric pressure changes.
Target the active bass during the falling barometer and the deeper bass during the cold front rising barometer, then after things normalize target the bass that have moved under cover.
