Wintry travel on Tuesday morning

12:15 PM, Monday, December 14, 2015

Expect accumulating snow late tonight and on Tuesday morning to impact ground and air travel. The highest impacts are likely in the Cheyenne area and on the northeastern plains of Colorado, with moderate impacts for the Denver-Boulder-Fort Collins corridor, and minor impacts in Colorado Springs.

 

Timing

Monday Evening: the chance for snow increases in mountains , especially in southern Wyoming and central Colorado.

 

Late tonight and Tuesday morning: main snowy period for the Front Range and adjacent plains. Increasing winds on the Colorado plains and in the Cheyenne area. 3-9 AM will be probably be the peak snowfall period.

 

Tuesday afternoon: snow tapers off from west to east. Maybe some significant snow and blowing snow out east on the high plains of northeastern Colorado.

 

Accumulations

Mountains: generally 6-12 inches, highest accumulations in north-central Colorado (around Vail Pass and Steamboat). Nederland is likely to be on the lower end of that range.

 

Cheyenne area: 5-8 inches, blowing snow.

 

Metro Denver-Boulder-Fort Collins: 2-5 inches. Blowing snow, especially east of I-25. A slight shift in track could result in little or nothing, or add a few more inches, but that appears to be a very small chance at this point.

 

Colorado Springs: 0-2 inches

 

Bottom line: A paralyzing storm is not expected, but winter travel conditions are expected by Tuesday morning. The worst conditions won’t necessarily be in and near the foothills.
