SHORT TERM /THROUGH TUESDAY/

Issued at 225 AM MST Mon Dec 15 2025

It will be dry and warmer today with high cloudiness invading from the southwest. Temperatures will be about 10 degrees warmer than yesterday across the plains, with readings similar to yesterday across the mountains and valleys. The upper trough moves across the area late this afternoon through tonight. It lacks moisture however, so the forecast area will remain dry. Winds will be light today before they increase late tonight as the upper trough crosses the mountains to our south and the gradient aloft increases again behind the system. The surface lee trough will kick eastward overnight allowing for enhanced westerly drainage winds to pick up along the lower eastern slopes into the I-25 corridor. This will keep overnight low temperatures on the milder side especially after midnight. Didn't make too many changes from model blends. -KT

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Issued at 225 AM MST Mon Dec 15 2025

Warm and dry on Tuesday as upper ridge flattens across Colorado, with a modest increase in winds over the higher terrain in the afternoon as mid/upper level flow begins to strengthen. Still looks very windy Wednesday into early Thursday morning, as strong upper jet (250mb winds 160-170 kts) noses into the central Rockies. Cross-sections don't show much of a mountain wave Wed as forward shear dominates with jet overhead, though simple brute force mixing may boost winds into the 60-70 kt range over the higher terrain by Wed evening, as broad area of strong mid-level flow (50-70 kts at 700mb) migrates across srn Colorado. Not quite as windy lower elevations, though still could get close to high wind criteria (50 kts) along I-25 and across Fremont County, especially Wed evening. Blended model numbers continue to run too low with wind speeds, and again went with speeds closer to the top end of the guidance envelope. Combination of warm temps, strong winds and low humidity will increase fire danger all areas Wed, greatest risk of critical fire weather conditions will be along the I-25 corridor from Pueblo south, were relative humidity may fall-off below 15 percent for a few hours in the afternoon. Quick burst of some windy snow showers likely Wed afternoon/evening over the central mountains as jet and upper wave swing through, though snow ends quickly by early Thu morning, keeping accums light.

Cooler with less wind Thu as trough and jet pull away, before warmer and windier conditions return from Fri through the weekend, as strong westerly flow continues across the wrn U.S. A couple embedded waves will bring snow showers at times to the peaks along the Continental Divide, with some light accums possible over the central mountains Saturday, then along the entire Divide by late Sunday.
