Look in the boxes and see if they are full of bees. If they are only half full, I would not put a super on. If they are 80% or more, I WOULD.
It's a blizzard here right now. I can't get get out of the driveway because it's drifting so bad. I80 was closed across the whole state. The idea of putting a super on now, is beyond my comprehension. :)
