SHORT TERM /THROUGH MONDAY/

Issued at 203 PM MDT Sun Aug 23 2026

Tonight: For Sunday night, active weather continues for portions of south central and southeastern Colorado. A ridge of high pressure will be remain in place just south of the area, with rich monsoon moisture streaming up and around this feature and into the area. This moisture tap, along with influence from vort maxes and shortwaves, will help showers and storms ongoing during the late afternoon to push across the plains through late evening to early overnight. While shear will be lackluster, a couple of strong storms will be possible given increased CAPE values. The strongest storms may be capable of producing heavy rainfall and flash flooding, along with gusty outflow winds to around 55 mph from wet microburst/heavy water laden downdrafts. Along with that, given the moisture in place, showers may continue to fester across the higher terrain and valleys into the late evening. With that all said, showers and storms are expected to dissipate by the mid overnight hours, with dry conditions by tomorrow morning. Outside of all of that, with the pattern in place, winds are expected to remain light outside of storms, less than 10 mph, with pockets of clouds persisting through much of the evening and overnight hours. Looking at temperatures, another warm and above seasonal lows night is anticipated given the moisture and cloud cover. The plains will cool into the 60s, the valleys into the upper 40s to upper 50s, and the mountains into the low 40s to mid 50s.

Tomorrow: Heading into Monday, another similar day to the past couple is expected for south central and southeastern Colorado. The high pressure will continue to sit south of the area, and continue to stream deep moisture up and around and into the region. Again, with influences from vort maxes and shortwaves, another round afternoon showers and storms is anticipated, with initial development along the higher terrain, and increasing in coverage across the valleys and plains heading into mid to later afternoon. Heavy rainfall, flash flooding, and strong outflow winds to around 50-55 mph will be possible with any stronger storms. Beyond of all that, also similar to the past couple of days, winds will remain light, around 10 mph, outside of influences from storms, with clouds increasing in coverage through the afternoon hours. As for temperatures, another warm and above seasonal day is anticipated. The plains will warm into the 90s, the valleys into the 80s, and the mountains into the mid 50s and upper 70s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/

Issued at 203 PM MDT Sun Aug 23 2026

Monday Night - Saturday: For the rest of the forecast period, active weather continues for south central and southeastern Colorado, though with a downtick in activity heading into the later part of the week. The stubborn high pressure will remain in place through at least the first half of the week, bringing additional abundant moisture. This moisture, along with any vort maxes and short waves, will bring additional days with afternoon and evening showers and storms, with the greatest coverage Tuesday and Wednesday. Then heading into the later part of the week, the high pressure is expected to drift southward and flatten out. This will eventually cut-off the deeper moisture tap, with showers and storms decreasing in coverage past Wednesday, but especially Friday and Saturday. Otherwise, winds continue to remain relatively light, with increased cloud cover expected each afternoon. As for temperatures, while a dip is expected midweek, temperatures remain warm and mostly above seasonal values, especially heading into next weekend.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1122 AM MDT Sun Aug 23 2026

KCOS, KPUB, and KALS: VFR conditions are expected over the next 24 hours. Outside of thunderstorms, winds are expected to remain relatively light, around and less than 10 knots, with only occasional gusts 15 to 20 knots. Dry conditions at the start of this TAF period will give way to storms this afternoon and early evening. Storms may bring periods of heavy rainfall, reduced visibility, gusty outflow winds, small hail, and frequent lightning to any of the TAF sites. Otherwise, mid to high level clouds will increase in coverage today, with a decreasing in coverage overnight and into tomorrow morning.
