I hope so. I am figuring to be on the ice on Sunday (depending on the wind). With 4 days of sub-freezing temps for highs, I think the ice should be 2-3 inches in most spots not on the main lakes (but I am no expert). If you want to go icefishing this weekend, do what I will be doing and bring a change of clothes, wear the lifejacket, have ice picks with easy accessibility, don't bring out the expensive gear, and tell someone where you are going to be at.
Good luck, and let me know how you did if you go out.
