As outlined yesterday, the warm weather Denver is experiencing today will be short lived -- our next system is fast approaching and will drop temperatures by 30+ degrees Saturday and bring another round of snow to Colorado.
Snowfall totals across the Front Range are forecast to be in the 1 - 4 inch range at this time. There is pretty decent consistency between most of the models this morning, with the exception of the GFS which continues to want to bring higher totals to the area. It's hard to accept this solution given GFS performance issues with these systems and the fact that it remains the outlier, but should the right conditions come into play we may need to bump up totals in a few locations. The tricky scenario with this storm will be "banding," where some locales will do much better than even their immediate neighbor. We have accounted for this event in the totals and Bust Index above.
The northern and central mountains are forecast to do quite well with this system. The northwest flow has a way of busting high for places like Steamboat ski resort where totals could easily exceed 12 inches by Saturday night. All of the northern and central mountains are currently under winter weather warnings and advisories through Saturday.
In addition to the snow, this system will bring a good injection of cold air back into the state. Highs Saturday are expected be mostly in the 20s across northeast Colorado, with overnight lows dropping into the single digits. The cold sticks with us through Monday, before temperatures slowly begin to moderate by midweek.
