KEY MESSAGES

- Shower and storms will continue into this evening. Flash flooding concerns continue over the Aspen Acres.

- Showers and thunderstorms continue on Thursday, with warmer and drier conditions Fri/Sat.

- Moisture looks to increase late this weekend and into next week.

SHORT TERM /THROUGH THURSDAY/

Issued at 1242 PM MDT Wed Aug 26 2026

Another round of afternoon showers and storms will move through the area this afternoon and into this evening. Convection will continue forming over and near the higher terrain, pushing east-southeast.

Latest observations and analysis show a window of high instability (1500+ J/kg of CAPE) over the eastern plains, and though there is some capping present, diurnal heating and some lift from a passing disturbance aloft should be enough to break through. The main impact concerns through this evening will largely be heavy rainfall and subsequent flash flooding over the burn scars. Further east, storms will increase in both strength and coverage as they encounter more moisture and better shear, bringing on the threat for large hail and gusty outflow winds as well.

Lingering convection will move off into Kansas later tonight, and barring any outflow interactions, we should dry out into early Thursday morning.

Tomorrow will be, overall, pretty similar to today, if a few degrees warmer. Models indicate a bit higher instability present over the mountains, with less moisture and instability over the eastern plains. Activity out east will be a bit more isolated in nature, while another day of flash flood risks will be in play for our burn scars. We may also see a strong to marginally severe storm around the Pikes Peak Region, where the more moist air will be influenced by the topography of the Palmer Divide thanks to northwest flow aloft.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/

Issued at 1242 PM MDT Wed Aug 26 2026

The upper ridge will amplify over the region on Friday and Saturday, with the center of the high pressure settling just south of Colorado. This will give us a brief period of warmer and slightly drier conditions. High temperatures will be in the mid-high 90s out east, with some portions of the eastern plains exceeding 100 degrees on Saturday. The monsoon plume will be moved out of our immediate area, but lingering moisture at the mid to low-levels, combined with diurnal heating, will still allow for isolated to scattered convection each afternoon over the mountains.

On Sunday, the ridge will shift east as an upper low moves onshore from the Pacific Northwest, bringing a new surge of moisture into our area. Daily showers/storms will increase in strength and coverage over the mountains, with more storms moving over the eastern plains as well. Cooler air will move in behind a cold front sometime on Monday, with temperatures settling back around seasonal normals.

AVIATION /18Z TAFS THROUGH 18Z THURSDAY/

Issued at 1119 AM MDT Wed Aug 26 2026

VFR is mostly expected at KALS, KCOS, and KPUB through 24 hours. Showers and thunderstorms will form over the mountains after midday, passing by the terminals after 22Z. Given scattered coverage, included as PROB30s for now, but will need to be mindful of outflow at KCOS and KPUB later in the evening. Outflow winds from storms are expected to exceed 30 knots, with any stronger storms approaching 45- 50 knots in more isolated gusts. After about 03Z tonight, convection will move away from the terminals and VFR will persist with winds near or below 10 knots into Thursday.
