Updated at 509 AM MST Sun Dec 21 2025

- Increasing clouds midweek with low chance of rain showers for areas near the Continental Divide and west.

DISCUSSION

Issued at 902 PM MST Sat Dec 20 2025

Tranquil weather continues through the early week as the zonal flow aloft turns more southwesterly and the upper ridge shifts to the east. Winds will be generally light under fair skies through Tue with near-record, fall-like temps.

Longwave troughing develops along the West Coast by midweek, creating unsettled weather for the Desert SW. Most of the impacts will remain west of our area, but increased cloudiness and showery activity is modeled to reach western areas on Wed. The Gila Region is most likely to see precip (20-30% chance), which would be light and all rain with snow levels holding AOA 10kft. Elsewhere, rain chances are very low (about 10% or less). Troughing persists over the West Coast for the rest of the week with zonal/SW flow overhead. Mainly dry conditions are expected for us after Wed, including X-mas. Passing shortwaves could result in breezy PM winds and increased clouds, otherwise no impacts are expected. The next storm system to watch out for would move in next weekend from the Pacific, but models have a wide range of solutions as it approaches our CWA.

Temperatures stay at record warm levels through most of the week with lowland highs into the 70s. Highs will be around 15 degrees above normal each day. A slight cooldown is being hinted at next weekend as we head into the new year, but still above normal.

AVIATION

(12Z TAFS) Issued at 509 AM MST Sun Dec 21 2025

VFR conditions through the period at all terminal sites. A broad ridge of high pressure is keeping the region fair, dry, and mild. Moisture is diverted well north, with skies mostly SKC. Winds will slacken a great deal from yesterday's breezy conditions, with speeds in the 5-10 knot range, favoring a westerly component.

FIRE WEATHER

Issued at 509 AM MST Sun Dec 21 2025

Mostly only minimal changes to the forecast, as the big picture weather pattern evolves slowly and unremarkable for the next few days. Yesterday's shortwave, that kicked up breezy afternoon conditions has passed, with broad gentle ridging back in charge over the SW U.S. This means moisture kicked back to our north, for mostly clear skies, and lighter pressure gradients, and lighter winds. Daily temperatures, under the ridge will continue quite above the seasonal averages, but about 15 degrees. The afternoon min RH will continue to drop into the teens through Tuesday, at all elevations, after poor to moderate overnight/morning recoveries in the 40-50% range. However, winds will be lighter during this period, to reverse the trend toward elevated/near critical fire weather.

After midweek, we see some troughing over the West Coast, which will turn our trajectories aloft from the SW. This will tap some mid and upper level subtropical moisture, and stream plenty of clouds over the region. This will flatten temperatures, and lift RH moderately across the region. Deeper moisture and dynamics from a passing/lifting upper storm system from the west will allow for some slight chances of light rain/snow over the far western areas, around the Continental Divide. The rest of the region looks to remain dry.

Ventilation will be limited through midweek, with a mix of poor and fair, and briefly good rates, then improve late week as troughing aloft moves in to deepen mixing, and winds increase.
