Hey Jeremy,
Normally after a cold front like went through last night I would go deeper. But there is a quick recovery with a high around 60 for tomorrow. Depending on time of day I might try both. Shallow early to see if they are there. Then a little deeper (10-15 feet). But I would hit the shallows again as the day warms. Especially if you notice shad activity shallow. I don't think I would be deeper then 15 feet if I could help it. Especially for black crappie and with the fresh water that is coming into the system.

Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
