After more than 20 inches of snow fell in some parts of Colorado between Sunday and Monday afternoon, another round of snow is now on the way – and although previous forecasts said it could also result in high snow totals for the Centennial State Mapping suggests it could have significant impacts along the Front Range.

To illustrate, when a snowstorm moves into Colorado, the National Weather Service releases a series of maps showing the expected snowfall total (80 percent chance), the “top” snowfall forecast (10 percent chance), and the “low-end” snowfall. -Snowfall forecast (10 percent chance).

Let's start with the most likely “expected” snowfall forecast, with the totals below expected to fall between Tuesday evening and Thursday morning –

In this scenario, parts of Colorado will see up to 24 inches of snow Tuesday through Thursday, favoring the Sangre de Cristos west of Westcliffe. Other central and southern mountains could reach heights of up to 18 inches, with up to 12 inches widespread in this region of the state.

In this most likely scenario, Colorado Springs will get about 3 to 4 inches of snow, Denver will get about 2 to 3 inches, and Castle Rock will get about 6 to 8 inches.

Where things get really interesting is the “high-end” snowfall forecast (seen at the top of this article).

In this scenario, overall sizes in the 12- to 18-inch range are much more common – and they are not limited to the mountains. The busy area between Colorado Springs and Castle Rock could end up with totals in that range, with up to nine inches of snow expected in the city of Colorado Springs, up to 11 inches in Castle Rock and up to six inches in Denver. Walsenburg could get up to 14 inches, with peaks northwest of this southern Colorado town having a chance of up to 30 inches.

If this “high-end” scenario occurs, impacts on travel are likely. With more than a foot possible on I-25, that's a recipe for chaos. It's also worth noting that this “high-end” scenario shows a lot of snow on a large portion of I-70 east of Denver. Travel could also be tricky in this part of the state. Be prepared for long commutes and pack your vehicle with winter vacation essentials.

And then of course there is the “low-end” forecast. In this scenario, some mountains reach heights of 20 to 30 cm, although not many peaks reach more than that. The most densely populated areas along the Front Range are largely overlooked.

So there you have it – there could be heavy snow in Colorado over the next few days, with potentially big impacts. Follow the changing weather forecast on the National Weather Service website.
