MEMPHIS, Tenn. — Winter is here and the Winter Solstice is upon us. Every December 21 marks the Winter Solstice, or Equinox, which is also the shortest day of the year.

In the Memphis area, temperatures Tuesday are expected between 34 and 54 — about average for this time of year. But get ready, because by Christmas Day this weekend, those temperatures will rise to a very un-winterlike level near 70 degrees.
