I wonder if ice freezing on top of the ice bonds as well as ice freezing at the base?
This rain could make the ice unpredictable. Some lakes it might help, others it might hurt, depending on how the ice was before the rain.
I say unpredictable because the rain won’t sit on the ice evenly. Most likely it will flow and collect in certain areas. Obviously then another big factor is how much you get and in what period of time.
Looking at Accuweathers forecast, unless I make it up to Grand Rapids, I won’t even think about ice fishing until after Christmas.
