Well I read quite a few articles on the matter and Ive read that they can increase a bass' strikezone, make it smaller, and really not change.  We have a small cold front  10-13 degrees difference comming through St. Louis and temps have been in the low 90s (I think, Ive been on vacation).  

I am sure the bass will tell me how they are acting once I get on the water but I much rather figure this out within the first hour instead of taking a while.

I've never had much luck after a big cold front moves, especially when accompanied by rain. I've never quite understood why as with the Midwest heat a cold front isn't going to have much, if any effect, on water temperature, but for me the bite always goes cold for 24-48 hours.

I wish we would have a cold front here--that might take us down to something tolerable. Anyhoo, it has been my experience, during summer cold fronts, that the effect on the fish is not half what it is during the winter cold fronts. IN fact, I have seen them more readily bite because it drops the water temp to a degree they actually seem to enjoy. Of course, the pressure may slow them down, but your best bet during any cold front---smaller baits, more subtle approach. They'll be close to cover

We had one moving in to northern VA yesterday evening, yesterday was in the high 90s to low 100s, today highs will be 85.  I love fishing when a summer cold front is moving in.  The bass seem to get really aggressive on cranks and on spook top water baits.  I missed it last night, but will try and get it tonight.  

Freshwater fish can feel the change in barometric pressure and they feed heartly before the cold front approaches.

When the cold front arrives they hunker down and since they have already eaten their fill, they do not get active again for about 24 hours after the front has passed and the weather conditions stabilize.

With that said, we had a cold front pass through Richmond, Virginia last night with some light rain and this morning at 5:50 AM and I caught the 6+ pound female in the local pond on a black buzzbait.

I then proceeded to catch four more bass on Senkos during the hour I was fishing.

So, although the fish do hunker down when a cold front passes and eat their fill there is still no rule set in stone about cold fronts.  

You can find more information on cold fronts in various publications, too, so read up on them and educate us all in the forum.

Just go fish and see what happens and put your adventure in your memory box for future reference.
