GFS – Total
NAMNST – Total
NAM – Total
We should note that changes in the snowfall totals are likely since several factors are uncertain. One of those factors is how fast the cold air and snow will be able to overtake the very warm ground following highs in the 90s and low 100s.
However, Snowfall is likely on the Interstate 25 urban corridor, including Cheyenne, Denver, and Colorado Springs.
Power outages Possible!
Given it’s still early September, many trees still have their foliage in Colorado and in neighboring states.
The heavy, wet snow on this vegetation could result in tree damage and power outages in some areas.
