.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 MONDAY/...
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.

VFR TAFs are expected to persist outside some temporary reduced
vis within evening convection. Monsoon moisture will remain

patterns should become commonplace outside of storm outflows
this evening.
