According to the forecast discussion, a strong cold front will move south from Canada today, bringing with it falling temperatures and another period of accumulating snow. This system could see snowfall totals up to a foot before another system moves in on Friday.

Overnight lows this weekend could fall into the single digits to teens below zero.

For Friday through Sunday, another potent and even colder system is expected to move through the region late Friday into Saturday and bring another round of accumulating snow, gusty winds, and unseasonably cold temperatures. There are some discrepancies on how much snow this system will produce but accumulations of another 3 to 7 inches seem likely for most areas, with higher amounts along the Divide and over higher terrain.

This system will be followed by another blast of cold air, with more record cold temperature records possible. Low temperatures in the single-digit and teens below zero seem plausible, while highs struggle out of the teens.
