.SHORT TERM /THROUGH MONDAY/...
Issued at 210 PM MDT Sun Oct 5 2025
A few showers have popped over the eastern Uintas and over the
northern mountains as the next upper level trough approaches
from the northwest. Minimal precip coverage is expected
however. Some midlevel ceilings can be found across the northern
valleys while elsewhere mostly sunny skies are the rule. After
cold frontal passage, temperatures have dropped noticeably this
afternoon anywhere from 10 to 15 degrees from what we saw last
week...a nice fall afternoon actually. Whatever precip remains
this evening will end overnight as the upper level trough
continues to be draped across Wyoming down through Nevada and
remains fairly stationary. Tomorrow, more of the same with
plenty of sunny skies expected across the region though more
clouds are anticipated along the CO/WY border. Highs will bump
up 2 to 5 degrees from what we`ll see today. We might see a very
isolated shower along the Continental Divide of the northern
mountains but chances are only 20%. Another nice fall day
expected.

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Issued at 210 PM MDT Sun Oct 5 2025
A weak Rex Block will set up over the western CONUS on Tuesday with
a closed low off the coast of California. This places our CWA under
confluent upper-level flow with drier air to accompany. Stronger
moisture will persist south of us across New Mexico though, and as
the blocking pattern breaks down into Wednesday, we should see this
anomalously high moisture drift northwards over us. This rise in
local PWAT`s will be gradual as the open wave over the PacNW will be
slow-evolving. Regardless, look for afternoon PoP`s to rise steadily
from Wednesday onwards. On Wednesday, precipitation potential will
be confined almost entirely to the high terrain of the San Juans.
Ensemble PWAT`s should begin exceeding 200% of normal (or
potentially over 250% of normal if we are to believe the ECMWF) by
Friday. This should be enough to support more widespread rainfall
across the region when paired with falling heights ahead of the
building longwave. Models aren`t too optimistic with instability
though, which could be trending us towards more of a steady, wetting
rain as opposed to convective-type storms. It`s too early to know
for sure, especially without CAM`s. As another note, with surface
and mid-level temperatures increasing throughout the week, forecasts
look to keep the precipitation type as almost entirely rain aside
from possible flurries reaching the highest peaks. This moist,
southwesterly flow could persist into early next week, so don`t be
surprised if showers are a daily occurrence for the foreseeable
future.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1118 AM MDT Sun Oct 5 2025
Skies are anticipated to be clearer and winds calmer for most of
the region throughout the next 24 hours. Some broken mid-level
clouds could linger over KHDN and KVEL for a while though.
Regardless, rain should remain to our north today and tomorrow
with VFR conditions prevailing.
