Key Takeaways:
- A winter storm is expected to impact Colorado this weekend, with significant snowfall predicted for the high country
- Travel impacts are expected to be significant, with delays and potential overnight closures on Interstate 70
- Snow totals in the high country are expected to range from 4 to 12 inches, with up to 18 inches possible in the far northern mountains
- Forecast confidence is lower for the Front Range, including downtown Denver, with a realistic range of a trace to 5 inches of snow
- Temperatures will play a significant role in the storm’s impact, with initial snowfall likely to melt on contact due to warm roadways
Introduction to the Storm
A significant winter storm is forecasted to impact Colorado this weekend, with two distinct forecasts emerging for the state. The high country is expected to receive substantial snowfall, while the Front Range, including downtown Denver, is predicted to experience a more uncertain outcome. The storm system, which is currently affecting California, will bring an atmospheric river to Colorado, resulting in accumulating snow in the high country early Saturday morning. As the storm progresses, impacts will increase along the I-70 corridor and during peak ski traffic, with confidence high in the mountains.
Snowfall Predictions for the High Country
The high country can expect significant snowfall, with most locations predicted to receive 4 to 8 inches of snow. Higher elevations can expect 6 to 12 inches of snow, with areas near Vail Pass and the Eisenhower Tunnel potentially receiving up to 12 inches. The far northern mountains, including Rabbit Ears Pass, may see up to 18 inches of snow by Sunday morning. These snow totals will have a significant impact on travel, with delays and potential overnight closures on Interstate 70 likely. It is advised to delay mountain travel until later Sunday morning if possible, as roads should improve relatively quickly once snowfall tapers off.
Travel Impacts and Road Conditions
Travel impacts are expected to be significant, particularly late Saturday night into early Sunday. Delays are likely, and overnight closures on Interstate 70 cannot be ruled out. The Colorado Department of Transportation (CDOT) will be monitoring road conditions closely and will implement closures as necessary to ensure public safety. It is essential to check road conditions before traveling and to plan for alternative routes or delays. Additionally, drivers should be prepared for winter driving conditions, with snow tires, warm clothing, and emergency supplies in case of an unexpected closure or breakdown.
Forecast Confidence for the Front Range
Forecast confidence decreases for the Front Range, including downtown Denver. The realistic range for snowfall remains anywhere from a trace to 5 inches, but confidence is higher that snowfall will land somewhere in the middle of that range. Current projections call for 1 to 3 inches along the I-25 corridor, with up to 5 inches possible in the foothills. However, temperatures will play a significant role in the storm’s impact, with initial snowfall likely to melt on contact due to warm roadways. As a result, a messy, slushy accumulation is expected, with most roads remaining wet to slushy and localized slick spots, especially on bridges, overpasses, and untreated surfaces.
Temperature and Road Conditions
The warm temperatures leading up to the storm will have a significant impact on the road conditions. Highs will reach 59 degrees on Saturday, with snow arriving roughly 12 hours later. Much of the initial snowfall will be lost to melting, especially on roadways. While snow may fall for several hours overnight, one to two inches could melt on contact, resulting in a slushy accumulation. This will make road conditions hazardous, particularly on untreated surfaces and in areas where snow is able to accumulate. Drivers should exercise caution when traveling, reducing speed and increasing following distances to account for the slippery road conditions.
Conclusion and Preparations
In conclusion, a significant winter storm is forecasted to impact Colorado this weekend, with the high country expected to receive substantial snowfall and the Front Range experiencing a more uncertain outcome. Travel impacts are expected to be significant, with delays and potential overnight closures on Interstate 70 likely. It is essential to check road conditions before traveling and to plan for alternative routes or delays. Additionally, drivers should be prepared for winter driving conditions, with snow tires, warm clothing, and emergency supplies in case of an unexpected closure or breakdown. By being prepared and staying informed, Coloradans can navigate the storm safely and minimize its impact on their daily lives.
