The answer is when do you stop? I know it's cold but even in the wientr you can get those 3 days of sun with a high of 50-60 the last day of warm weather is good i find myself getting shallow bass that come up to warm on cover or structure( rocks, fallen trees, docks etc..) that holds heat. If it is cold then go deep, you may need a fish finder to find them. When they suspend in cold water you can use spoon, jigs, drop shot rig or jerk bait. Fish slower too If fishing n the cold is not for you then like most people wait till it warms. You can catch bass in the cold and if you can bear the elements quality fish can be caught too.
