KEY MESSAGES

- Above seasonal temperatures through the end of the week.

- A few more showers/-tsra today and tomorrow

- Active weather returns to the region starting Sunday, lasting into next week. It could be a rather impactful event as a fairly high amplitude, stout, Pacific 500 mb trough moves across the region.

SHORT TERM /THROUGH WEDNESDAY/

Issued at 1158 PM MDT Mon Oct 5 2026

We will see a few more showers and storms over the mountains today as a jet streak develops to our west and south, and an area of upward vertical motion moves across the region. Most of these showers and thunderstorms will occur across the Continental Divide, especially from the La Garita mountains north-northwest across the central mountains. Over the remainder of the high terrain showers will be more isolated. The plains are expected to be dry.

As for temperatures, today will likely be the hottest day of the forecast period. We will likely see a record today, as KCOS record is only 82 and the fcst is for 84. Pueblo record is 91, and the max temp is fcst to be 87. Alamosa record is 79 and the fcst hi temp is 75.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/

Issued at 1158 PM MDT Mon Oct 5 2026

For Wednesday, it will be a few degrees cooler over the region, however we will still have some weak favorable lift over the region as the jet will still remain just ot our west and south. Likewise will still see the best chance of showers and storms as today, however we will see a bit better chance of some showers and storms over the plains.

Thursday through Saturday, Temperature will be similar all 3 days, with Upper 70s to mid 80s over the plains and 65 to 70 over the mtns, Isolated to scattered showers will continue over the mtns during this time period as moisture will linger over the higher terrain.

Sunday things are likely going to begin to occur as a strong Pacific trough pushes in from the northwest and begins to develop a significant trough over the western one third of the CONUS. Both the deterministic GFS and EC show this trough, but differences in moisture/orientation/track and timing are noted between the guidance, and this variability is shown in the statistical products. Overall confidence is high that it will get much cooler/(colder) early-mid next week and the mountains will likely see precipitation.

Overall, how impactful this system will be dependent on how much tropical/subtropical moisture aloft will be advected into the region, and this will depend how much moisture from tropical cyclones off the mexican coast will be drawn into the mid level trough.

There is still quite a bit of uncertainty with this system, but there is potential this could be a higher impactful event affecting our region next week. \/Hodanish

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 452 AM MDT Tue Oct 6 2026

There is a very low potential for patchy ground fog again for an hour or two around sunrise at KALS, though odds look too low to include in the TAF given some high cloud cover over the area. Otherwise, it will remain VFR today at all three TAF sites with variable high cloudiness at times. Winds will be generally light and diurnally driven with speeds under 15 kts. -KT

PUB WATCHES/WARNINGS/ADVISORIES

None.
