Barometric Pressure
This is definitely on the main factors that influence bass fishing.  I've read many articles on how this influences bass behavior and how to locate bass in different barometric pressure situations.

Here is what I have found both in my research and in practical tournament experience:
- As the barometric pressure rises, bass will move deeper.

- The opposite holds true for when the pressure falls - bass will move shallower.

- Below 15 feet bass are not usually affected by barometric pressure. 

- A high barometer indicates a post front condition, a low barometer means a pre front condition.

- Rule of Thumb - High, clear, blue skies indicate a post front or "A High", referring to high barometric pressure. Generally you want to use a post front pattern for a minimum of  about 3 days. Cloudy, gray skies or rain indicates a pre front condition or "A Low" in the area, Low referring to low barometric pressure.  Use a pre front pattern until the front passes.
