KEY MESSAGES

- Dry conditions with afternoon high temperatures 10-15 degrees above normal persist through the week.

- Breezy winds are likely Tuesday afternoon over the high terrain. Little to no snow accumulation is expected.

SHORT TERM /THROUGH MONDAY/

Issued at 1209 AM MST Sun Feb 1 2026

High pressure is firmly in place over the Intermountain West, bringing quiet conditions to the CWA. We're running 10 to 15 degrees above normal as a result. Deterministic models indicated a shortwave will swing through tomorrow afternoon, which will briefly bring high temperatures down (though still well above normal). A slight uptick in moisture will accompany this upper- level feature, but it's highly likely that this will result in little more than cloudy skies.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 1209 AM MST Sun Feb 1 2026

Much of the work week will be quiet while under the influence of a building high pressure ridge sitting to our west. This will provide mostly dry conditions with above normal temperatures for the first week of February with highs around 10 to 15 degrees above normal. As the high pressure ridge sits to our west, our CWA will be under a northerly flow. A weak shortwave will drop southward down the Front Range on Tuesday with light snow possible along the northern and central Divide mountains, although models keep pulling this wave further east with each run so any accumulation looks minimal with lack of dynamic support. At the very least, we could see some breezy conditions over the high terrain. The high pressure ridge will slide overhead by Friday as a low pressure system pushes onto the SoCal coast. This will allow high clouds to increase across the area Friday into Saturday. Potential for any precipitation is very low and confidence is low with the forecast trending more towards a drier solution. There is quite a bit of uncertainty with how this SoCal low is going to evolve with some solutions cutting it off, keeping us on the drier side of things. Temperatures may cool slightly across the north and along the Divide with the Tuesday wave but overall, temperatures don't appear to budge much day to day with highs around 15 degrees above normal by the end of the week.

AVIATION /00Z TAFS THROUGH 00Z MONDAY/

Issued at 936 PM MST Sat Jan 31 2026

High level clouds continue to increase over the region, bringing scattered to broken skies through 18z tomorrow. Ceilings will remain well above breakpoints, so no impacts to airports are expected. Winds will be generally light and terrain driven through the period. VFR conditions will prevail.
