PUEBLO, CO – Southern Colorado could see a significant weather pattern change Monday through Wednesday, Oct. 12 14, as a Pacific storm system brings increasing mountain precipitation, possible high elevation snow and cooler conditions across the plains.
According to the National Weather Service in Pueblo, a strong Pacific trough is expected to move across the region through midweek, although uncertainty remains regarding the storm's exact track and intensity.
The San Juan Mountains are expected to experience some of the greatest impacts. Persistent southwesterly winds could transport substantial moisture into the mountains, with several inches of liquid equivalent precipitation possible from the weekend into midweek.
Colder air arriving Tuesday into Wednesday could change some of that precipitation to snow at higher elevations. The Weather Service has not provided specific snowfall totals or snow levels.
Across the southeastern Colorado plains, including the Pueblo area, very warm and dry conditions are expected to continue through Monday.
By Tuesday, temperatures could begin falling as showers become possible across portions of the plains. Unsettled conditions may continue into Wednesday, depending on the storm's eventual path.
Forecasters emphasized that the system remains highly dynamic, with several possible outcomes for southeastern Colorado.
Depending on the storm track, portions of the plains could experience warm, windy and dry weather or a cooler, wetter pattern.
Mountain travelers should prepare for the possibility of winter driving conditions across Continental Divide passes later Tuesday and Wednesday as colder air reaches higher elevations.
The Weather Service recommends monitoring updated forecasts as confidence improves in the storm's track, precipitation coverage and potential snowfall.
For now, residents should expect continued warmth across the plains through Monday, followed by a possible transition to cooler, showery weather Tuesday and Wednesday, while mountain areas face the greater precipitation and snow potential.
