SHORT TERM /THROUGH THURSDAY/

Issued at 111 PM MDT Wed Sep 9 2026

For the rest of today, mot much in the way of precip is expected. If any showers develop through 6 pm, they will be down near the southern Sangres and isolated over the far SE Plains. Max temps today should generally be in the 80s plains and valleys.

The interesting weather will be tonight. With plenty of low level moisture over the plains and a somewhat degraded moisture plume aloft, combined with a fairly stout disturbance at mid levels will move over the region later tonight. Showers and thunderstorms will develop over the plains by early to mid evening and increase in intensity and coverage into the early morning hours of Thursday. The main concern with this activity will be locally heavy rain, especially over the far eastern plains where deeper moisture is noted in the data. Some local flash flooding can not be ruled out and we are under a slight risk for flash flooding over the plains later tonight.

for tomorrow, there will likely be quite a bit of low clouds over the plains tomorrow morning, and some showers may still be ongoing over the far eastern plains early tomorrow morning. Skies will clear by late morning and it should be a rather nice day with max temps only in the lower to mid 80s plains and mid 80s valleys. Some isolated late afternoon thunder may occur along the mtn/plains interface tomorrow afternoon

It will be dry and warm in the mtns and breezy at times. An elevated fire weather risk is expected, mainly over the La Garita mtn range.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/

Issued at 111 PM MDT Wed Sep 9 2026

Friday...we warm up once again and expect temps around 90F over the plains with mid 80s valleys. Only isolated storms are expected in the afternoon/early evening. We will see a bit more of a fire weather risks today as it will be breezy and dry, and Elevated fire weather conditions will once again be possible over the San Luis Valley, the lower elevations of Fremont and Chaffee counties and western Pueblo county.

Saturday...a fairly stout cool front move down the plains Saturday morning. However showers and thunderstorms are still expected to by mainly isolated over the region. It will be cooler with highs in the 80s across the valleys and plains.

Sunday...Temperatures are forecast to shoot up again, with values in the mid to upper 90s across the plains and mid 80s valleys. showers will be isolated across the plains.

Another cold front moves across the region late Sunday into early Monday and and max temps at the beginning of the week fall back down in the 80s Monday, with even cooler weather moving into for Tuesday. We should see a better chance of showers and storms on these two days as we will see the monsoon plume get reinvigorated over the region and a disturbance comes across the region.

It appears an unsettled pattern will remain across the region through the rest of the week bringing in some cooler weather and better chances of precip. \/Hodanish

AVIATION /18Z TAFS THROUGH 18Z THURSDAY/

Issued at 1118 AM MDT Wed Sep 9 2026

The main concern for the TAF will be the potential for low cigs at KCOS and KPUB during the overnight hours, especially between about 0900 UTC to 1500 UTC. A convective cluster of thunderstorms is expected to develop over the eastern plains tonight and this may send a moist outflow boundary back towards the mountains, and we could see a low overcast develop at the 2 taf sites. We may also see some showers (and low chance of some tsra at KPUB) during this period. Otherwise we will see VFR at KCOS and KPUB.

KALS will see VFR next 24 hours.

PUB WATCHES/WARNINGS/ADVISORIES

None.
