Ok, so here in central Texas we just got our first cold front of the fall, and I'm not sure how it will affect the fishing.  Average temps for about the past month have been highs about 95-100, and lows 75-80.  Now, and for the next couple days, forecast has highs about 85, and overnight lows down as cool as 55.  Ordinarily, I know cold fronts will put a halt to the fishing.  But the fishing here has been slow because of an extremely hot summer, so will the front improve things?

Wait until Thursday & I'll tell ya  

In what terms are you speaking? Sounds as though temps is your main concern. The air temp will have no affect on the fishing. It will however have an affect on water temp and the water temp is what you want to watch. We can have 2 or 3 cooler days of air temp without much change at all in water temp. However, as little as just a few degrees in water temp can turn the bite on when coming out of our hot Texas summers. Right now is the time to be fishing in north Texas. The water temps are down in the 80's for the most part and I have seen high 70's in the early morning hours. Where you are, the changes may take a little more time, or not. As far as fronts are concerned, there are 3 types of fronts and it is believed by many that they all effect the bite differently. For this time of year we are concerned with the cold front. Immediately before the front and a day after the front passes should prove to be good fishing. To answer your question, the cold fronts along with cooler nights and milder days have already started bringing water temps down. Start watching for the shad and other bait fish to start heading into creeks and coves. The Bass will be following. I have already been catching them in 2 feet of water in the early morning hours, and out a bit deeper as the sun gets up higher as in late morning. Use lures that will mimic the shad. Don't be afraid to use a T-Rigged brush hog if you like soft plastics. Keep in mind that the water temps will not change as fast as the air temps. A lot of people get on the water on a relatively cold morning assuming they need to slow down their presentation or start finesse fishing patterns. Not necessarily, check the water temps. Depending on how cold the air temp is, it could take several days of cold air temps for the water temps to fall significantly. I hope this helps. Good fishing.

Thanks.  You're right though, the bite has certainly turned on.  I caught three small ones in about 20 casts with a crank in 2-4 feet the other morning.  That's compared with one fish over a day of fishing.  And I could see many others schooled up in the shallows, though they were all pretty small.

Try fishing 6 to 8 feet of water for the larger ones. Off points is good. Also, you should be able to find balls of bait fish, not necessarily Shad, but smaller minnows schooled up in deeper water. The larger Bass will be under them, along with Sandies. Shad colored cranks, and even chrome spoons free falling through the bait ball will get you bit.
