The mountains have seen several light snowfall events over the past week, but the next storm impacting Colorado will deliver snow to almost everyone.
The high country straddling I-70 is set for a 6- to 10-inch snowstorm, with 3 to 6 inches likely for the Foothills and Palmer Divide. The I-25 urban corridor and eastern Plains can generally expect 1 to 4 inches of snow by the end of the storm.
Moisture will quickly begin to increase after dark Monday evening. Snow levels at the onset of this event will generally sit around 9,000 feet. The mountains will start with snow, while the urban corridor and eastern Plains will start off with periods of rain.
Cold air will continue to take hold into Tuesday, which will allow snow levels to rapidly lower after midnight. By daybreak, the entire urban corridor and adjacent Plains should see snow falling.
Most forecast guidance suggests that the height of the storm is Tuesday morning. This is when several intense snow bands could set up across northeast Colorado, as a low pressure system starts to intensify over the southeastern corner of the state. The snow will then taper off from north to south into Tuesday afternoon.
The snowfall forecast for this particular storm is a tad trickier than normal, especially in the Denver area. The timing of the changeover from rain to snow is the biggest wild card. An earlier changeover would yield higher snow totals. A changeover later Tuesday morning would yield very low snow amounts, as most of the moisture from this storm would fall as rain.
The other challenge revolves around the banded nature of the snowfall. If heavy snow bands sit over the same area for most of Tuesday morning, locally higher amounts will accumulate. Denver has an outside chance of seeing snow amounts approach 6 inches, should these heavier bands set up over the city.
In any case, roads around Denver on Tuesday will be on the slick side. Mountain roads will be snow-packed and icy with the higher totals and the lower temperatures.
Denver International Airport still has not seen measurable snow this November. The normal monthly snowfall is 7.4 inches. Now we need to wait and see how much the city can cut into the November snowfall deficit in the next 36 hours.
