KEY MESSAGES

- Slight upturn in storm chances today, especially along the Continental Divide. Continued dry and hot from I-25 eastward.

- Isolated high terrain storms continue Tuesday and Wednesday, best chance of storms over the eastern San Juans.

- Increasing moisture and thunderstorm chances then expected along/near the Continental Divide from Thursday into the weekend, with measurable rain likely. Activity tapers off to isolated over the eastern mountains, with only spotty/light rainfall, while I-25 and the plains stay dry.

- Still some hints of Monsoonal moisture possibly working into all of the region early next week as upper level high pressure wanders through the Rockies.

SHORT TERM /THROUGH TUESDAY/

Issued at 1238 AM MDT Mon Jul 13 2026

Slight increase in moisture today (mainly along the Continental Divide) will produce a minor upturn in convection, with the eastern San Juans having the highest pops from mid-afternoon into the evening. Farther east, convective build ups may produce a few sprinkles and gusty winds over interior valleys and the eastern mountains, though a few CAMs show a couple of weak storms over the Sangres drifting westward through the San Luis Valley toward 00z. I-25 and plains remain dry, and steering currents will again tend to move storms w-sw. Max temps may drift upward a degf or two on the plains, though most of the area will end up with in a couple degf of yesterday's numbers.

Similar set-up on Tuesday, with best moisture remaining south and west of the area and thus the greatest chance for storms again along the Continental Divide (San Juans most favored for a storm once more). Mid level heights and temps decrease just slightly Tue as center of the upper high slides into the central plains and weak upper low drifts eastward over the srn Mississippi Valley. Set-up may drop maxes just a couple degf from Monday's readings, mainly on the plains.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Issued at 1238 AM MDT Mon Jul 13 2026

Upper low drifts westward into TX on Wed, with hints of a weak spoke of energy rotating westward across srn Colorado late Wed afternoon. As upper ridge over the srn Rockies weakens slightly, deeper moisture creeps back northward into the area, with an upturn in convection over the swrn mountains, and scattered activity farther north along the Continental Divide and across the southern Sangres. Suspect we'll begin to see measurable precip with storms near the Divide as moisture increases, and some local quarter inch plus amounts look possible over the ern San Juans. Steering flow again looks unfavorable for eastern mountains/I-25/plains to see storms, as activity will again tend to move westward. Center of the upper high then gradually shifts/reforms back over the Rockies from the end of the week into the weekend, keeping a modest inflow of mid level moisture in place across wrn CO. Expect scattered to numerous storms along the Continental Divide through the period, with perhaps some substantial rain totals (over 1 inch) possible by Sunday, mainly over the ern San Juans. Precip chances and amounts taper off quickly over the ern mountains and interior valleys, though even here some spotty light precip is possible. Still not enthused about precip along I-25 and on the plains Fri-Sun, though if upper high can wobble back slightly more w-nw (especially Sunday), upper level winds may shift to the nw, potentially moving storms over the higher terrain back onto the plains. Max temps may creep back upward slightly as heights/mid level temps warm at bit, with the potential for some 100f readings on the plains Sat/Sun.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

Issued at 518 AM MDT Mon Jul 13 2026

VFR conditions anticipated across the forecast area over the next 24 hrs, including the three main TAF sites of KCOS, KPUB and KALS. Slightly better chance for some afternoon and early evening convection over the higher terrain, especially along the Continental Divide today, but should not affect terminals. Both KCOS and KPUB will see surface winds become SE between 18z and 08z with afternoon gusts to 25 kts possible. KALS will see S-SE surface winds between 20z and 07z, with occasional gusts to 22 kts.

PUB WATCHES/WARNINGS/ADVISORIES

None.
