Frigid Temperatures Noted Across
  Western & North Central Nebraska

With fresh snow cover from the recent snow storm - overnight low temperatures plummeted to readings well below zero at all automated airport sensor locations. The coldest locations were in the Platte River Valley, where cold air drainage allowed very cold air to slide into the region.
