The weather here in eastern washington state has been the same for the past few days, very windy and overcast but in the mid to upper 50's.  Last night it got a bit colder and rained very hard all night long but temps never dropped below freezing, now today it is a bit windy but looks as if it may get sunny and warm.  The question I have is, would that drop in temperature yesterday be considered a cold front or does it have to get much colder for a longer period of time? Should I fish the areas/presentations that have been working or is it not worth the effort because they may have moved deep? I fish from the shore and have been finding them back in the shallow coves tucked in the reeds and i can't cast to most drop offs or points out in the bigger areas of the lake from the shore.  Thanks in advance for any help/advice.

I would say thats a cold front, usually a low front is refered to as a cold front because of the temp change. As far as fishing goes your the fish may have moved deep or will be holding tight to cover. If the sun stays out most of the day the fish may be come more active. I would continue with your current tactics, but I would slow them down or try to penetrate the cover more. If that doesnt work try to fish as deep as you can, you may intercept them coming back in.

Thanks for the reply, there are alot of reeds up in these coves that i have been fishing and the wind has been blowing alot of debris and garbage into there it almost seems like it would warm up that water quicker in a way but regardless of that it IS good thick cover I think I'm gonna have to go give it a try. Thanks again.

I'm no meteorologist, but a cold front is the leading edge of a moving air mass that is colder than the air it will replace. It's usually accompanied by rising pressure, clearing skies and a shift in winds to the N or NW.

as a cold front is coming, the barometer will start to fall steadily, you'll see lots of clouds starting to form, there will be some rain, with winds outta the south or southwest.

When you're IN a cold front, you can see really gusty, shifty winds, a real sudden drop in temperature, a sharp rise in the barometer, heavy rains, or at least strong rains, possible storms,

AFTER a cold front, the winds will change to north/northwest, the barometer rises steadily, and usually clear skies.  

I agree with what they've said.  Before a front can be a great time to catch bass.  They can sense a change coming and will often turn on right before the front pushes through.  If the front is not real strong, the fishing will get slower, but can still be really good.  A couple of years ago, a buddy and I continued to catch good numbers after a wind shift to the north.  We caught all of them right up tight in the reeds and grass.  Don't pack it in when a front comes, just get in tight with your baits and fish a little slower.

Thanks alot for all the info, there were bass up in the reeds but i had to throw to spots numerous times and work my lures very slowly then they would just pick it up and sit there with it.  It was alot different than a couple days ago but they didn't go far, they just slowed down.  Thanks again  ;D

this reminds me of a story. (What a surprise ;D)

anyway it was in the middle of July about 90 degrees or so, and my buddy said the fishing will be good because a "cold front" was coming.  Temperature dropped all the to 89.
