Past 2-3 weeks have been very nice weather, as hot as 90 and mostly 70's-80's.

Yesterday it probably dropped to 65, and today it's 59degrees right now with a possible high of 69.

I've been fishing very successfully the past few weeks but not sure how the weather will change the fishing.

Please any advice would be great!

Sounds like it could be a jig and Senko day.  The water temperature probably hasn't dropped that much, though so they may not be affected that much at all.  They don't always do what they are supposed to do.

I'd fish it 2 different ways:

Fast and Furious

Slow and Steady

Either of those ways should win the race.  You'll get the active fish that weren't turned off by the weather, and then you can slow down and get those lock jawed fish.  

Personally I'd start out throwing a spinnerbait and run it no deeper than you can see all the way.  This will pick up the active fish and sometimes when you stir up the bite even the sluggish fish will come up to see whats going on.  Then I'd throw a weightless worm and fish it at the most 2 ft deep, but thats just me.
