Temperatures in the teens, snow and freezing rain is in the forecast for the next 10 days according to multiple weather sources.
According to Firsthand Weather, this is due in part to the polar vortex and should be moving into our area towards the later part of this week.
The transition to a much colder pattern should begin soon. Without getting into too much detail about how this map product is generated, the blue (red) shaded region indicates where temperatures should be below (above) average over the day 9-11 period.
