SHORT TERM /THROUGH TONIGHT/

Issued at 1253 PM MDT Mon Aug 31 2026

Overall, most of the region, especially the higher terrain, should see precip between now and late night tonight. The least amount of precip will be over the far southeast part of the plains. flash flooding will be possible along the Divide.

The I-25 corridor may see 2 rounds of precip today. The first will be the normal showers and storms coming through during the normal late afternoon and early evening time period. Best activity is expected to from along the Raton Mesa later this afternoon and move north-northeat. Activity farther north during this time period will be more isolated. Later this evening, a more pronounced short wave will move across and this will likely bring a better chance of showers and some tsra to the I-25 corridor region.

Looking at the weather for the mountains, we will see a better chance of showers and storms later this afternoon, this evening and into the early morning hours. The better chance for heavier rain will be over the central mountains, and areas such as the Chalk Bluffs and Willow burn scar will have to be watched carefully for flash flooding through this period.

LONG TERM /TUESDAY THROUGH SUNDAY/

Issued at 1253 PM MDT Mon Aug 31 2026

Although the monsoon plume will stay over the region this week, the quality of the moisture will be less. Likewise, showers and storms will be possible over the region, but there will be less activity Tuesday through the Thursday time period. Overall, expect scattered storms in the mtns, and isolated activity over the plains.

From Friday into the weekend, Deterministic guidance shows moisture increasing through the column during this period. and showers and storms should become more prevalent over the region during this time period. This same overall pattern is indicated by the statistical guidance. Warmest temps should occur late in the week. 100s may come back to parts of the far east plains Friday and Saturday. A bit of a cooling pattern possible by early next week, but there is disagreement in the guidance about this outcome.

Checking the fire weather parameters during this forecast period, we may see some spotty conditions on Thursday across a small part of the region.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1121 AM MDT Mon Aug 31 2026

A couple of rounds of showers and thunderstorms may be possible at the taf sites this late afternoon and evening, with main concern being gusty winds in and around the convective activity. The main forcing will move across KCOS and KPUB during the 02-05 UTC time period. Otherwise anticipate VFR conditions through the period with primarily light diurnal wind flow.
