Here is the forecast snow from a single model (the NAM) valid through 6am Sunday morning. If this is roughly correct, and it is in line with earlier forecasts, I-70, I-80, and I-76 could be impassible and/or closed given that there will be enough wind, at least in places, to officially qualify as blizzard conditions.

I urge you to be aware of this storm if you are planning travel in these areas. Note: The heavy snow will affect the Denver airport.
