The chance for precipitation climbs quite high by late morning and early afternoon, meaning most areas will eventually get wet on Thursday. Once the rain completely changes over to snow, any accumulation will be minor with up to 1 inch on the grass and surfaces still covered from the snow that fell last week.

The snow will end during the evening and skies will gradually clear Thursday night into Friday morning.

Precipitation will start with rain because there is no genuine cold front with this storm. It originated in southern California and will move into Colorado from central Utah which is a somewhat unusual storm direction for December.
