The early freezing lakes that already have quite a bit of ice should be alright as long as the water level doesn't rise too much, heck may even fish in a hoodie or maybe tshirt this weekend if not too much rain comes. Nights are going to be cold next week, so should simply firm any slush or water on top of the ice back up.
But its going to wreak havoc on the ones that are just starting to cap, primarily the bigger lakes. This last cold spell was pretty disappointing for getting new caps forming, with all the wind and snow.
Only in PA do we go from teens/ single digits, to 60s, within a few days.
