DENVER -- Expect another abnormally warm day Tuesday with a high of 68 degrees in Denver, Boulder, Loveland and Fort Collins.
A big wave cloud will sit over the Front Range, blocking some sunshine.
The mountains stay partly cloudy with mild temperatures in the 30s and 40s.
There will be two storm systems arriving in Colorado between Wednesday and Friday.
The first delivers rain and snow starting in the mountains by Wednesday afternoon. There will be 2-4 inches of snow accumulation above 8,000 feet.
The rain will transition to all snow by Thursday morning. There will be a lull before the second storm system arrives Thursday afternoon.
Rain showers start in Denver by 3 p.m. Wednesday. It changes to a rain/snow mix by 6 p.m.
There will be 1 inch of snow accumulation or less for the evening commute. Temperatures on Wednesday will be in the 40s.
Thursday will be cloudy and colder ahead of the second storm system. Snow arrives late, after 9 p.m. There will be 1 inch of snow accumulation.
A Pinpoint Weather Alert Day has been issued for Thursday because the evening commute could turn slick as snow develops.
Snow continues for the Friday morning commute, then stops and skies clear. One inch of snow accumulation is possible.
In the mountains, another 4-8 inches of snow accumulation will be possible Thursday and Friday.
That puts the grand totals from the two storms at 6-16 inches. There will be much heavier amounts of 1-2 feet or more in the southern mountains.
It will turn drier on Friday afternoon. It will be a dry weekend with highs in the 50s.
Next week looks quite stormy and colder. There could be a couple of shots of snow for Colorado before and possibly just after Thanksgiving.
