I would like to add some things which I will para-phrase (rather than quote because it is too long)from SPOONPLUGGING a "GUIDE TO LUNKER CATCHES" by Buck Perry, the father of structure fishing.

BUCK SAYS:

When fishing YOU SHOULD NOT THINK OF WEATHER IN TERMS OF TEMPERATURE OR PRESSURE.—You should VIEW WEATHER IN TERMS OF LIGHT. The lighter or brighter it is, the tougher the fishing will be. The darker the conditions, the better it will be.

(Grumpy’s note: Buck is generally referring to daytime and SUMMER TIME conditions here.)

Using the COLD FRONT as our starting point, lets look at it in terms of LIGHT. The pre-frontal conditions are normally dark conditions, with heavy cloud cover (and a falling barometer), rain or showers. After the front goes through, the cooler mass of air moves in (with rising barometer) and you will normally have a bright clear, blue sky.

PRE-FRONTAL CONDITIONS, WILL GIVE GOOD FISH MOVEMENTS (feeding) AND POST-FRONTAL CONDITIONS WILL GIVE BAD, OR LITTLE MOVEMENT OF FISH (not feeding).

The day following a cold front normally has a clear blue, washed out sky. A beautiful day, and usually windy.. FISH—DEEP AND INACTIVE...

(Grumpy’s note: Buck goes on to list conditions for the next few days after a cold front passes, each day getting clouder and less bright, with increasingly better fishing condtions.)

The day of a cold front—heavy threatening clouds, threatening rain and falling pressure. When the rain starts, the fish will have already moved into the shallow water and will be biting like crazy.

The day after the front passes will dawn BRIGHT AND CLEAR, high pressure will have set in and the fish will have gone deep.

The cycle repeats itself over and over, sometime longer and sometimes shorter, in between fronts but it never stops changing.

(Grumpy's note: I hope this helps.)
