KEY MESSAGES

- 100s return to a good portion of the plains TODAY. Isolated storms this evening

- Cooler Wednesday, FLASH FLOODING of the Aspen Acres (AA) burn scar possible once again on this day.

- Getting warm again late week/weekend then cooling with monsoon flow returning early next week.

SHORT TERM /THROUGH TONIGHT/

Issued at 1206 AM MDT Tue Aug 18 2026

100 degree readings will once again return to a good portion of the plains today, with readings from 100 to 103 from roughly Pueblo east to the KS border and down towards Springfield. 90s will occur rest of the plains and mid Ark Rvr valley areas, with upper 80s in the larger valleys.

As for precip today, not likely. We may see some very isolated showers over the region by late afternoon, with a slightly better chance of showers and storms over the southern mtns and I-25 corridor during the evening hours as a cool front pushes down the plains this evening. Once the cool front moves down, low level moisture will improve over the plains, and we could see a few storms develop along behind the front over the plains and I-25 corridor region through the overnight hours. There is a low chance we could see a strong storm or two along the southern mtns/I-25 corridor region (including the AA burn scar) tomorrow evening.

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 1206 AM MDT Tue Aug 18 2026

For Wednesday, the FLASH FLOOD threat will return to the AA burn scar sfc upslope flow combines with northwesterly flow aloft. Guidance shows best moisture (and related instability) will be pinned along the mtns/plains interface and I-25 corridor region. This could allow strong storms to push southeastward along the southern mtns, bringing a heavy rain threat to teh AA burn scar during the afternoon time period. In addition to the heavy rain, shear will be sufficient for rotating storms and severe storms will be possible along the southern mtns/I-25 corridor region. Max temps will be about 10 degrees cooler on WED as compared to TUE.

Looking at Thursday into the weekend, it will get warm once again with temps peaking around 100 across parts of the plains with 90s elsewhere across the lower elevations and 80s in the valleys. There will be some moisture noted in the mid levels so isolated to scattered storms will be possible each day most areas, with better chances of storms over the CONTDVD region.

By next week, a more favorable pattern for showers and storm develops as a more favorable monsoon pattern develops over the region. This is reflected in the deterministic guidance along the NBM data plots for the region. Temps will also cool down a few degrees during this period. \/Hodanish

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1054 PM MDT Mon Aug 17 2026

KCOS and KPUB: VFR conditions are expected over the next 24 hours. Winds will continue to remain light, around and less than 10 knots, tonight and into early tomorrow afternoon. As diurnal mixing develops, winds will increase to maintain around 10 knots, with gusts to around 20 knots possible. Then tomorrow evening, a cold front is expected to push southward, which will quickly shift winds to become northerly if they haven't already from shower outflows, and increase post FROPA. Otherwise, mid to high level clouds are expected to start increasing tomorrow afternoon, with scattered showers developing late afternoon and through the evening. Any shower that impacts either TAF site bring periods of moderate rain, with gusty outflow winds.

KALS: VFR conditions are expected over the next 24 hours. Winds are expected to remain relatively light, at and less than 10 knots, through this TAF period. Beyond that, dry conditions with periods of mid to high level clouds is anticipated.
