KEY MESSAGES

- Quick-moving disturbance to bring snow to the mountains this afternoon and evening, which will make for slick and hazardous travel.

- Drier and warmer conditions starting Saturday.

UPDATE

Issued at 642 PM MST Wed Nov 4 2026

Latest high-res model trends continue to produce moderate snow across Lake County through this evening and into tomorrow morning. Given this, and based on a recent report of 5 inches of snow already in Lake County, a Winter Weather Advisory has been added to the lower portions of Lake County.

SHORT TERM /THROUGH THURSDAY NIGHT/

Issued at 1237 PM MST Wed Nov 4 2026

Currently...Temporary ridging across the state is allowing for plenty of sun and a pleasant day across much of southern CO. Temps as of 11 AM have warmed into the 40s for the high valleys and 50s for the plains, and are expected to climb another 5 to 10 degrees through the afternoon. A closed upper low was quickly pushing across UT and will be the next weather maker for the region.

Tonight through Thursday morning...Quick-moving upper low will create a wide range of weather on the front end of the forecast. The upper low centroid pushes into western CO this afternoon, then slides to the east-southeast through the evening, then eventually moves across the SE corner of the state through the morning. This latest solution places the upper low slightly further south than previously thought, which shifts the focus out of El Paso County and moreso to the Walsenburg/Trinidad/Raton Pass area. What this translates to is a quick blast of snow across the mts tonight, with the greatest amounts expected over the central mts. A Winter Weather Advisory is in place for the higher peaks of Lake and Chaffee counties, along with Pikes Peak, for 4 to 9 inches of new snow along with some isolated higher amounts up to 11 inches, through 5 AM tomorrow morning. In addition, rest of the area will likely see some showers as well as isolated thunderstorms late this afternoon and evening as a cold front dives south across the eastern plains. The main threats from storms will be cloud to ground lightning and wind gusts as high as 45 mph, but the cold front itself will bring gusty northerly winds 30 to 35 mph. Finally, there is the chance of an hour or two of snowfall over Monument Hill, mainly between 10 PM and midnight as snow levels fall tonight, that could create reduced visibilities and slower travel conditions. However, feel that the ground is still warm enough and no accumulation is anticipated at this time.

Again, this system is moving incredibly fast which multiple model runs support, so deteriorating conditions will be short-lived.

Thursday afternoon and evening...Upper trough continues pushing to the east-southeast through the afternoon, into the central US plains, allowing for improving conditions and an end to lingering showers over the southeast corner. Gusty northerly winds through the morning will be on the wane as well. Plan on plenty of sun through the afternoon and mostly clear skies skies at night, though cloud cover will be on the increase from the west late. Look for highs in the mid 40s to lower 50s for the high valleys, and 50s to around 60F for the plains. Overnight low temps will drop into the 20s for the high valleys, and 30s for the plains. Moore

LONG TERM /FRIDAY THROUGH WEDNESDAY/

Issued at 302 PM MST Wed Nov 4 2026

By Friday, the band of elevated 500mb vorticity, should have filtered out of the area, leaving us with ridging aloft. It may be possible for westerly flow, combined with modest humidity, to produce orographic precipitation on the windward side of the higher terrain, especially the central mountains, in the afternoon. For the rest of the area, expect a dry, partly cloudy day.

Moving into this weekend, we will enter a ridging pattern, with temperatures slightly above average, with mostly sunny conditions and light winds. The next chance of widespread rain looks to be, at the earliest, Wednesday of next week.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 456 PM MST Wed Nov 4 2026

Rain and snow showers will are included with a Prob30 in all TAF sites, with higher confidence for over KCOS and KPUB. If a heavier shower reaches the sites, MVFR or IFR will be possible, but otherwise VFR conditions are expected for all sites.
