UPDATE: focus of storm shifts back toward Front Range

6:15 AM, Monday, November 16, 2015

The trend keeping the worst impacts of the winter storm on the eastern plains of Colorado has shifted a bit, and the Front Range, especially the Denver area, appears to be more at risk for major impacts from snow and wind tonight.  The highest impact area is still likely to be the southern and eastern suburbs of Denver (including DIA) and the eastern plains.  But some significant impacts appear possible in other parts of the Front Range Monday night as well.

The storm is likely to begin its intensification while in southern Colorado Monday evening, which is a more favorable location for northeasterly upslope flow along the Front Range.

Timing: Some precipitation, perhaps rain, should be around Monday afternoon. Snow is likely Monday evening into Tuesday morning, lingering longer on the eastern plains and at DIA. Considerable blowing snow is likely (especially east of I-25).


Denver (east and south sides), Palmer Divide region, eastern plains of Colorado: at least 6 inches, up to 12 inches in the Palmer Divide region and parts of the eastern plains. Blowing snow. Expect major travel impacts on the roads and at the airport.

Denver (northwest side), Broomfleld, Boulder: 4-7 inches, mainly during Monday evening and overnight.

North of Boulder (Longmont, Fort Collins, Cheyenne): 1-4 inches. Some blowing snow.

Mountains (Nederland): 4-8 inches , up to 12 at the high passes.

Colorado Springs: 3-6 inches north side, less on the south side. Blowing snow.

I will not be in a position to update with the morning guidance. Bottom line, be prepared for winter travel conditions beginning this evening. Major impacts possible by Tuesday morning, especially the south and east sides of Denver.
