.KEY MESSAGES...

- Dry and unseasonably warm conditions are expected during the
  remainder of the week. Near record highs are expected from
  Thursday through the weekend.

&&

.SHORT TERM /THROUGH WEDNESDAY/...
Issued at 429 AM MDT Tue Sep 24 2024

A long wave mid-level trough deepening and moving toward the
West Coast will drive high pressure over the Intermountain West
eastward today. Models were consistent in placing the ridge
axis directly over the forecast area by 06Z/Wed before the
trough forces it to the High Plains on Wednesday. In response to
high pressure, skies will be clear or mostly clear throughout
the next 36 hours with essentially no chance for precipitation.
Warming under the ridge will bring highs of about 5 degrees
above normal today and similarly mild overnight lows tonight. On
Wednesday, flow aloft shifts to the southwest behind the ridge
axis driving temperatures even higher with afternoon readings
climbing to near 10 degrees above normal and nearing record
levels for some locations.

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
Issued at 429 AM MDT Tue Sep 24 2024

Unseasonably warm and dry conditions continue to be the
highlight of the forecast through the weekend with high pressure
staying put overhead. Normal high temperatures for late
September are in the upper 70s, low 80s for valley locations and
in the 50s for higher terrain locations. However, it is very
likely that high temperatures will be 10+ degrees above normal
for the latter half of the week into the weekend. Some locations
may even see record high temperatures as some valleys will
likely warm into the 90s (60-90% chance).

.AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/...
Issued at 1018 PM MDT Mon Sep 23 2024

A few high clouds will continue overnight and through around
18Z tomorrow. After that, mostly clear skies expected. Some
chances remain for fog at KGUC Tuesday morning so included VCFG
in TAF as confidence not high enough to go predominant. Outside
of that, VFR conditions continue through the next 24 hours.
Light winds expected.
