Colorado — A quiet, cold start to the weekend across southern Colorado will soon give way to a potent burst of winter weather. The National Weather Service in Pueblo has issued a Winter Weather Advisory for the Eastern San Juan Mountains above 10,000 feet, including Cumbres Pass and Wolf Creek Pass, effective 2 a.m. to 5 p.m. Sunday.
Snow is expected to develop quickly before dawn Sunday, intensifying through midday. Forecasters anticipate 5 to 10 inches of accumulation, with the heaviest snow falling along the highest peaks and ridgelines. Drivers crossing U.S. Highway 160 should prepare for slushy, snow-packed roads and reduced visibility through the morning and early afternoon.
This advisory serves as an early reminder that winter travel has returned to the southern Rockies. Temperatures will drop sharply as snow spreads eastward, and gusty winds near exposed passes could worsen visibility. Motorists are urged to slow down, keep extra distance, and check 511 before heading through the high country.
The Sunday storm marks the start of a broader Thanksgiving week cold pattern expected to sweep across much of the western and central U.S. by midweek. Long-range models continue to hint at a major cold front moving in November 25–December 3, possibly bringing heavy snow and below-normal temperatures across multiple states.
