There are a number of patterns that have been working according to the reports. Drop Shot, Jerkbaits, Crankbaits, and the ole reliable Shakey Head. They have been catching some shallow but I would think with the coldfront you would want to target brush in the 20-35 foot range. Check the GON Forum for and

A lot of big spots coming off of live herring too.
