Labs,

I don't think this cold front will make for great fishing this weekend. Fishing never is great during a cold front. If you are on the water you always have a chance to get some fish.
If it was me I would look to be on the water the warmest parts of the day, which probably will be around 3:00p.m. or so.
If you are trying for musky I always seems to have good luck on cold fronts throwing mag. bulldawgs working them slower outside of the deep weed edges.
The saying is fish go deep during cold fronts, but I am telling you don't feel afraid to try it shallow like 4-5fow.

Good Luck! Let me know how the fishing goes.
