Pumpkin Spice Lattes are back and it's almost September, so we might as well have some snow too, right? Mother Nature must think so, because we are likely to see the first flakes of the season in Colorado tonight.
The storm system will move from northern Idaho to southwest Wyoming during the day on Monday and then pass directly over Colorado Monday night. The best chance for snow will be after 10 p.m. above 10,000 feet in the mountains along and south Interstate 70. Any accumulation will be minor and generally range from a dusting to 1 inch.
Snow in late August is not necessarily uncommon although many years the first snow waits until September in the Colorado high country. The only month of year when snow is extremely rare in the mountains is July.
The average first snow in Denver is October 18.
