9:30 AM MST, Sunday, January 20, 2019
A total lunar eclipse will occur this evening beginning and 9:41 PM and lasting until 10:43 PM. There is a lot of upper level Pacific moisture that could result in some cirrus clouds, but it’s worth a look if we are in a clear area at that time
The next Pacific storm will move through late Monday. Snow may begin impacting mountain areas (especially the west side) Monday afternoon, but probably hold off until evening along the Front Range and eastern plains. Once again there is not likely to be much easterly (upslope) flow, so the heaviest snow won’t necessarily be near the foothills. Rather, there is likely to be some north-south gradient with the heaviest along the north-facing slopes of the Palmer Divide.
3-6″ for the mountains and the Palmer Divide region, including Castle Rock and the far south suburbs of metro Denver.
2-4″ for the Denver-Boulder metro.
0-2″ for northern Boulder county and up into eastern Larimer and Weld counties.
2-4″ Cheyenne area
1-3″ Colorado Springs
The snow should be mainly overnight Monday into early Tuesday morning.
