We're expecting plenty of sunshine across the Twin Tiers this weekend courtesy of a large area of high pressure.  Despite the sunshine, however, it will be on the cool side with highs both Saturday and Sunday in the lower 60s.  Overnight temperatures will bottom out in the lower 30s with areas of frost likely.  Skies will remain mostly sunny through at least the first half of next week with temperatures expected to warm back into the 70s and possibly near 80 by Thursday.
