I'm not the most experienced person on this forum by a long shot but last winter was a tough one for me as well. Due to weather and rain just haven't made it out a bunch this year. A couple of things I can offer:
1) Don't get too down as It's likely not just you, catching bass in winter or cold/terrible conditions IS just harder. They are more docile, don't want to feed as much, and at some points in deeper water which is typically harder to access from the bank.
2) I've looked at winter as good time to try some new techniques or organize gear for next season. One thing I'll do (assuming you go with more than one rod), is have one rod with a very finesse setup (Ned rig, light texas rigged soft plastic, etc.) and another with a more power fishing style (Crank bait, jerk bait, etc.) and try your luck at both in the same area that way you're covering all your bases. Don't be afraid to work your power fishing styles faster than you might think and don't be afraid to work your finesse setups slower than you might think.
3) Worst case scenario you're getting outside for a mental break and getting some exercise. Get you a couple podcasts, videos, audio-books (whatever you're into) queued up to make it so even if you don't catch anything you're still getting some knowledge or entertainment.
4) If you're just hunting a bite maybe look into crappie fishing? Someone else could hopefully provide some insight here as I seem to only ever catch them by accident and don't target them but I hear they are great eats and maybe more likely to bite in colder temps? I see a lot of people vertically jigging for them under bridges which can typically be accessed on foot.
Speaking at least of recent conditions, with iced up waters, heavy rain making water visibility less, and pretty decent swings in temperatures. All these things make it less than ideal for catching the ever illusive bass. Persistence is key and can't catch 'em if you don't have anything in the water - good luck and spawn will be soon enough!
