KEY MESSAGES

- One more very hot day on Tuesday, with a Heat Advisory for eastern Fremont, El Paso, and Pueblo Counties. Another round of windy afternoon convection also expected.

- Cooler temperatures then expected from Thursday into the weekend, along with widespread thunderstorms and increasing flash flooding concerns.

SHORT TERM /THROUGH TUESDAY/

Issued at 120 PM MDT Mon Aug 10 2026

Currently, upper high over nrn NM again today, with weak wly mid/upper level flow continuing to push a modest tap of mid- level moisture eastward across CO. Isolated -tsra already underway as of 1 pm over the higher terrain/Palmer Divide, and expect activity to continue to spread away from the mountains and across most valleys/plains from mid-afternon into early evening. Again, more wind (gusts 50-60 mph) than rain with most activity (DCAPE in th 1000-1500 J/KG range), though t/td spreads aren't quite as extreme as the past couple days as surface dewpoints have crept upward across the region. As a result, a few locations in the mountains/Raton Mesa area could see wetting rainfall under any stronger storms. Activity then wanes toward sunset and ends by midnight, with clearing skies into Tue morning.

For Tue, upper high continues to drift across nrn NM, though some subtle changes in moisture and temperature appear across the region. In general, moisture continues to slowly increase with scattered to numerous showers/thunderstorms over the mountains and isolated activity on the plains. Mountain convection has a greater potential of producing measurable rainfall in spots, while lower elevations storms will lean more toward gusty winds than meaningful rainfall for another day. Temperatures Tue should end up within a couple degf of Monday's readings, as mid-level temps drift downward a bit over the plains, but stay nearly the same over the mountains and along the NM border. Just hot enough for one more heat advisory for Pueblo/Colorado Springs/Canon City, with highs in the low 90s to 1ow 100s, and have re-issued the highlight for the afternoon and evening hours. Readings are forecast to stay below 105f across the lower Arkansas Valley Tue, so held off on issuance of highlights here.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Issued at 120 PM MDT Mon Aug 10 2026

Transition to wetter weather starts to accelerate on Wed, as upper high center finally drifts into the srn plains and monsoon moisture plume returns to Colorado. Greatest coverage of storms on Wed will be over the mountains/valleys, with pockets of heavy rain possible as air mass moistens. Storms less numerous east of the mountains, though swly steering flow should carry at least a few storms eastward onto the plains Wed afternoon/evening. Mountain max temps will cool several degf Wed as mid level temps fall and cloud cover becomes more widespread, while only minor cooling expected on the plains where readings could still exceed 100f over the lower Arkansas Valley for one last day. High then slides into the sern U.S. for late week into the weekend, with monsoon moisture well entrenched over Colorado through the period. Cold front late Wed/Thu will also bring back low level moisture to the plains and eastern slopes. Expect widespread showers and thunderstorms each day, with heavy rainfall and flash flooding possible as well. Temps will cool back into the 70s/80s through the period, which will be a few degf under seasonal averages for a change.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1139 AM MDT Mon Aug 10 2026

VFR conditions are anticipated during the next 24 hours at all taf sites. Will carry a prob30 for -shra/weak -tsra at all sites from mid-afternoon into early evening, with the main threat from any convection being gusty winds of 35-45 kts. Activity ends quickly this evening, with skies clearing and winds settling out to light drainage overnight.
