As Colorado gets a snowfall, the National Weather Service has released a map of expected snowfall to help residents of the Centennial State prepare for the approaching wave of winter.

Their mapping shows the snow forecast from 6 a.m. Saturday to 6 p.m. Sunday, showing that up to a foot could fall on the highest points of the Continental Divide during this period in the “most likely” scenario (see below). With the exception of the highest peaks, the mountains could see a maximum of six inches of snow, while some lower mountain valleys could potentially see up to three inches.

Below you will find a map with this forecast:

This weather will likely have the biggest impact on those planning to spend a weekend climbing the Fourteener, including some participants in the annual Pikes Peak Ascent and Marathon event.

As for this world-famous race, there is some good news related to the latest forecast. First, it looks like the 1,700 or so runners in Saturday’s Ascent will have pretty good weather, minus a few clouds. And second, it looks like the initial reports that Pikes Peak could get 21 inches of snow Saturday night, according to Mountain-Forecast.com, have changed quite a bit. Pikes Peak is now expected to get about seven inches of snow Saturday night, according to Mountain Forecast, with the National Weather Service estimating about the same potential.

Snow at this level will likely still have an impact on the Pikes Peak Marathon, which starts at 7 a.m. Sunday morning and runs 13 miles to the peak’s summit before heading back to Manitou Springs — not to mention temperatures at the summit will be in the 20s all day. That said, the impact will likely be far less than if the 21-inch forecast were to come to pass. About 800 runners are participating in the race, and while they’re required to wear a hooded waterproof jacket, the incoming snow may prompt many of them to consider shoe traction devices as well.
