Re: weather and fronts....
Hey there JD
Since you last had success with a spinnerbait I would try that to see if they are still on it. If not, try a red lipless crankbait. Winter time is killer for those especially when the water is in the 50's.
If nothing happens on those then move out a little deeper from the areas you were catching fish in with your SB and work worms, jigs, Carolina rigs or drop shots. If you were catching fish say in 5-8 foot depths with the spinnerbait then back out to the 10-15 foot depth and see if you can find a breakline. That is where the depth changes quickly from one depth to another.
If you are on foot then stick to the lipless crankbait. It is a great search bait. If you catch a few on that then try a worm in the same area.
There is so much more but this is a quick general help.
On warming trends I find fish are very active in the NW section of the lake as that is typically the warmest water. Sun beats on it good and it is protected by the north winds best.
Hope that helps.
