SHORT TERM /THROUGH SATURDAY NIGHT/

Issued at 121 PM MST Fri Nov 13 2026

Currently...Upper disturbance was pushing into southern AZ this afternoon, while across CO abundant high level cloudiness was in place, while low clouds and fog was finally dissipating across the eastern plains. Temps as of noon have warmed into the mid 50s to mid 60s for the plains, and 50s across the high valleys.

Tonight...The upper disturbance to the southwest opens up this evening as it slides east-northeast, becoming intertwined with the longwave trough that extends from British Columbia all the way down into Texas. This will bring snow showers to the Continental Divide starting around 7 or 8 PM, with snow levels between 8500-9000 ft for the sw mts, while the central mts drop from 9k feet to near 7k feet by daybreak. The sw mts are forecast to receive up to an inch of new snow tonight, while the remainder of the mts will likely just see a trace initially. However, snow across the sw mts will continue through the day tomorrow, leading to advisory amounts, so went ahead and issued a Winter Weather Advisory for the eastern San Juan Mts from midnight tonight through 9 PM for 4-8 inches of snow. Across the far eastern plains, there are some hints at low clouds and patchy fog redeveloping late tonight. Forecast grids do not show wide enough coverage to warrant any sort of fog advisory, but following shifts can reassess. Plan on overnight lows around 30F for the high valleys, and mid 30s to mid 40s for the plains.

Saturday and Saturday night...Upper disturbance continues pushing east across New Mexico through the day Saturday, then tries to close off and strengthen briefly over the southeast corner of CO Saturday night. This will lead to snow across the mts, and a rain/snow mix across the high valleys, through the day. Showers will spread across the eastern plains as well during the day, increasing in coverage and intensity through the afternoon and early evening as the system starts to wrap up. By midnight, precip should start coming to an end for the Continental Divide and high valleys, while across the eastern plains cooler air will spread southward on the backside of the system. A rain/snow mix is probably over Monument Hill and northern El Paso County Sat evening, switching over to all snow during the overnight hours. At this time, little accumulation is anticipated. High temps Sat will remain in the 40s for the high valleys, and 40s to lower 50s for the plains. Overnight lows will be in the 20s for the high valleys, and 30s for the plains.

LONG TERM /SUNDAY THROUGH THURSDAY/

Issued at 121 PM MST Fri Nov 13 2026

Sunday and Monday...Upper system exits the state Sunday morning, with just some lingering isolated showers across the southeast corner through the morning hours. Temporary ridging then fills in across the region through Monday, with the ridge axis pushing east by Monday afternoon as the next feature approaches from the west. Plan on dry conditions with initially cool temps, moderating on Monday. Highs on Sunday will be in the 40s to around 50F, then climbing into the 50s for the plains on Monday, while the high valleys warm into the 40s to around 50F.

Tuesday and Wednesday...Long range models indicate that another quick-moving system across the area mid-week, with the EC showing a deeper southern track while the operational GFS indicates a more glancing blow. Regardless, the trend is that this feature will bring much stronger southwest winds along with a similar amount of QPF compared to the Friday/Saturday system. This will amount to a period of wind-driven snow, focuses across the southwest mts and which will likely prompt another highlight at some point. Another difference with this system is that it looks like effects will be tied to the higher terrain, while the plains will remain dry. High temps across the plains both days will be in the upper 50s to mid 60s, while the high valleys will warm into the upper 40s to mid 50s on Tue, then just the 40s on Wed.

Thursday and beyond...Models paint a third system to affect the region starting Thursday evening, with some indications that this could be a stronger feature. Forecast snow amounts along the Continental Divide, though far too early, lean towards a significant event. Stay tuned. Moore
