KEY MESSAGES

- Very hot through Tuesday with Heat Advisories issued for Sunday over the the lower Arkansas River Valley and El Paso County

- Relief from the very hot temperatures begin on Wednesday with more widespread thunderstorms and flash flooding concerns for the rest of the period for the burn scars, urban areas, and areas with saturated soils

SHORT TERM /THROUGH MONDAY/

Issued at 1259 AM MDT Sun Aug 9 2026

The upper level high pressure center is located over the four corners region of the desert southwest. With the present location of the high, the western US is more favored for monsoonal moisture - however in the long term, this will set-up Colorado nicely for widespread thunderstorms when that ridge of high pressure begins to propagate to the east. For today hot temperatures are expected with high based convection that will lead to very strong outflow boundary. There is a Heat Advisory from 12pm to 8pm for the lower Arkansas River Valley and El Paso County with high temperatures reaching the upper 90s to around 108F over the plains. The mountain valleys will be in the upper 80s to low 90s. These elevated showers will develop primarily over the mountains but will move over the lower elevations throughout the afternoon and evening. Wind gusts up to 50 MPH are possible. As an example, late Saturday evening there was a rogue 70 MPH wind gust over Colorado Springs Airport - it's a similar atmosphere today as it was yesterday, therefore locally higher wind gusts are possible. Low temperatures will be in the low to upper 60s over the plains and the 40s to low 50s over the mountain valleys.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 1259 AM MDT Sun Aug 9 2026

Very similar high temperatures are expected on Monday as they are on Sunday, so we'll have to determine if we are going to issue another Heat Advisory during the forecast packages tomorrow. A little bit more moisture is expected on Monday, so perhaps a few more heavy raining thunderstorms across the region, but the predominant impact is expected to be gusty outflow winds once again.

One more hot day on Tuesday with thunderstorm coverage increasing once again - another Heat Advisory will be possible. By Wednesday the upper level high pressure is pushed to the SE, which will allow for all the built up monsoonal moisture to west to propagate to the east and for the main monsoon plume to move east, which will equate to more widespread showers and thunderstorms. There are elevated concerns for flash flooding over the Aspen Acres and 24 burn scars and over urban areas. As the week continues there will be a risk for flash flooding over areas with saturated soils.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1028 PM MDT Sat Aug 8 2026

Gusty erratic winds from high based cumulus/virga will be the main concern over the next 24 hours. A rogue gust to 60 kts occurred at KCOS this evening from very weak cells with no precipitation reaching the ground. Winds overnight through Sunday morning will settle into diurnal patterns with speeds under 10 kts as clouds continue to decrease overnight. However, another round of high based cumulus build ups with virga and very localized gusty outflow winds will be possible after 20-21z Sun at all three terminals. Although -SHRA will likely evaporate before reaching the ground, the unpredictable nature to wind directions necessitates a PROB30 group for KCOS and KPUB to carry -SHRA with VRB wind directions gusting up to 40 to 45 kts. Locally stronger gusts are possible into the evening but odds of impacting the terminals will be low. Will try to time the increase in winds at KALS with a prevailing group given the more predictable nature of the wind direction as storms move across the San Luis Valley. Winds should settle down after sunset, but can't rule out another isolated rogue gust should a weak cell move over the terminals again. -KT
