Predictions- warm rain/muddy them temp drop

Fishing a lake tomorrow, we have warm temps and a lot of rain yday/today...60 degree rain.  Cold front moving in tomorrow.  This past week has been the first warmup of spring.  
 

I know it’s a tough ask to predict but just looking to see what anyone thinks fish might do.  More specifically, fishing Lake Patoka in Indiana.  It’s a River created lake to mitigate flooding.  Not sure what the water temps have been but I’d guess it’s at least low 40s.  I’m mainly just wondering if they’d likely to still be hanging in deeper water.  20 feet would be dee in this place.
