ROCHESTER, NY (WROC) - Warmer air is almost here with temperatures climbing out of the single digits into the 20s and 30s. Snow showers work their way in from the west. Expect flakes to fly through the overnight, adding a few inches to the snowpack. Temperatures will be important to watch going into the next few days as to see how long the snow lasts. Christmas is cold, but Thursday and Friday will break above freezing and allow for some of that snow to melt away. Temperatures get into the 40s by the weekend.
