KEY MESSAGES

- Continued hot with just isolated thunderstorm chances for the higher terrain today and Monday.

- Precipitation chances start to increase Tuesday, then moreso for Wednesday into the weekend.

SHORT TERM /THROUGH TONIGHT/

Issued at 1234 AM MDT Sun Jul 19 2026

Currently...A little bit of cloud cover out there, left over from some late nocturnal convection, otherwise temps are expected to gradually cool through the overnight with lows in the 40s and 50s for the high valleys, and 60s across the plains.

Today and Tonight...Upper ridge of high pressure remains in place, with the high center directly overhead. This will mean another hot day in store for the region, along with just some isolated afternoon and evening convection over the higher terrain, with the greatest chances along the Continental Divide. Due to the spotty nature expected, flash flooding over area burn scars is not a major concern today. Plan on highs today in the mid 80s to around 90F for the high valleys, and 90s to near 100F for the plains. Overnight lows into Monday morning are forecast to be in the 50s for the high valleys and 60s across the plains.

LONG TERM /MONDAY THROUGH SATURDAY/

Issued at 1234 AM MDT Sun Jul 19 2026

Monday...Very similar pattern in place, compared to Sunday. The upper high directly overhead will produce another very hot day, and Monday is looking to be the hottest day of the forecast period with afternoon highs in the upper 80s to mid 90s for the high valleys, and mid 90s to low 100s for the plains. Forecast grids hint at a potential need for a Heat Advisory for Monday, but it is really spotty and would like some newer model input as well as another forecaster to take a look. There is some spotty critical fire weather conditions as well cropping up near the Aspen Acres Fire. There is not enough areal coverage to warrant a highlight at this time, but have ben in contact with AA IMETs to discuss this potential. Finally, it will be another day of isolated convection over the mts, with perhaps a slight increase across the central mts affecting the Willow Fire area.

Tuesday...Upper ridge axis shifts slightly to the east, which allows a weak front to drop south across the eastern plains. This shift also allows a gradual increase in moisture advection up across the Desert Sw and into western CO. Taken together, the result is NOT cooler temperatures but at least a slow increase in precipitation chances across the higher terrain, with isolated showers spilling over onto the I-25 Corridor through the late afternoon and evening. Plan on highs in the 80s to around 90F for the high valleys, and 90s to around 100F for the plains.

Wednesday through Saturday...Long range model trends indicate a rather strong upper shortwave crossing the Rocky Mt region Wed into Thu, then the upper ridge builds back overhead for Fri and Sat. Temps will remain hot, but the chance for showers and thunderstorms significantly increase starting Wed and continue into the weekend. As the ridge builds back overhead, it looks like moisture trapped under the high will recirculate each day, fueling afternoon and evening activity. The threat of flash flooding over area burn scars will be on the increase starting Wed. Moore

AVIATION /00Z TAFS THROUGH 00Z MONDAY/

Issued at 1046 PM MDT Sat Jul 18 2026

At KALS, clearing skies and decreasing winds overnight as convective cloudiness/outflows dissipate. VFR conditions through the day on Sunday, though a couple CAMs show some weak showers over the Valley in the late afternoon/early evening. Suspect high pressure building overhead will suppress convection, and won't mention any precip in the taf at this point.

At KCOS and KPUB, VFR the next 24 hours with drainage winds overnight turning to sely upslope 12g22kts after 18z Sun.

PUB WATCHES/WARNINGS/ADVISORIES

None.
