It’s that time of the year again – when wintery weather starts to come roaring back into the Centennial State.

While a few inches of snow have landed here and there in Colorado already this fall, it’s looking like the next few days will bring the most significant snowfall yet. It’s also worth noting that this will likely be a storm where mountain roads and lower elevation valleys get hit, too.

Based on reporting from the National Weather Service, some parts of the state’s northern and central mountains could get between eight and 18 inches if the ‘high-end’ snowfall scenario occurs (10% chance) between September 22 and the morning of September 25. Meanwhile, if the ‘expected’ and most likely snowfall scenario occurs (80% chance), expect peak totals to end up around eight inches.

Mapping depicts that one of the harder hit areas should be along Continental Divide in the area of Rocky Mountain National Park and just east of the Eisenhower Tunnel.

Ahead of the storm, Rocky Mountain National Park has already announced that Trail Ridge Road will be temporarily closing at 6 p.m. on Monday night from Rainbow Curve on the east side of the park to Milner Pass on the west side. Old Fall River Road will be closing at 5 p.m. It’s also worth noting that Longs Peak is expected to get quite a bit of snow – up to 12 inches based on some National Weather Service mapping. Meanwhile, Mountain-Forecast.com shows about 11 inches of snow in the forecast for the mountain through Tuesday afternoon.
