.KEY MESSAGES, Issued 1037 PM MST Sun Nov 1 2026...


- Accumulating mountain snow is expected across all Utah mountains
through  Monday morning. Upwards of 12" of snow is expected above
9000   feet, and 3-6" of snow down to around 7000 feet. Upper
elevations of the Cottonwoods and western Uintas may see   localized
accumulations 18-24".

- Cool, dry, and stable conditions build in Tuesday following the
passage of this system.

- A weak system looks to impact the region Wednesday/Thursday
ushering in a brief period of low elevation rainfall and high
elevation snowfall across primarily northern and central Utah.

.DISCUSSION, Issued 1037 PM MST Sun Nov 1 2026...
Currently, a mid-level trough is traversing across the
Great Basin with its axis nearly centered along the UT/NV border.
With this trough, a cold front continues to sweep across much of UT,
having already traversed the western half of the state. While the
lower levels are slowly drying out, weak ascent with modest moisture
aloft will result in light to occasionally moderate rainfall
persisting across much of the forecast area through roughly 09z.
From 09z on, higher terrain will be favored for precipitation given
drier low levels of the atmosphere. As such, the flood watch will be
allowed to expire at 06z for southern UT and portions of central UT.

700mb temperatures will continue to cool following the passage of
the cold front to roughly -3C to -4C resulting in snow levels
continuing to drop through the evening to around 6500ft.
Additionally, northwest flow aloft will persist, resulting in a
favorable pattern for widespread mountain snow across much of Utah`s
high terrain. Of note, a TROWAL feature has been identified via
satellite imagery serving to wrap more moisture around the northwest
side of a deepening upper low located over northern UT. This has
resulted in another round of widespread light to moderate rain
observed across northern UT, and will also contribute to snowfall
totals across our northern UT mountains. Across our UT high terrain
(generally 9000ft or greater), 3-6" of additional snowfall is
expected. Some areas, such as the Upper Cottonwoods and Western
Uintas may see additional snowfall totals from 6-12" given favorable
northwest flow orientation overnight.

Transient ridging builds in Monday in the wake of the deepening
trough as it progresses east. This will result in most precipitation
coming to a halt across the forecast area, though some lingering
showers across the UT high terrain may persist. This feature is
forecast to persist through Tuesday bringing quiescent conditions
and unseasonably cool temperatures, potentially as low a 15F below
seasonal normals areawide.

Ensemble guidance has come into better agreement with a weak mid-
level trough sweeping through the Great Basin on Wednesday. This
system is not expected to bring a whole lot of moisture with it, and
with weak forcing, only light valley rainfall with light mountain
snow accumulations are expected across northern and central UT.
Following this system, dry conditions develop once again as ridging
becomes dominant across much of the western U.S. through the
remainder of the week and into the weekend.

.AVIATION...
KSLC...As showers wind down this morning, expect to see improving
conditions, with prevailing VFR returning by 13z. However, CIGS may
remain below 7kft through 15-16z with mountain top obscurations.
Northerly winds will prevail before a shift to southerly drainage
winds occur around 02-03z.

REST OF UTAH AND SOUTHWEST WYOMING...As showers wind down this
morning, expect to see improving conditions across the airspace, with
prevailing VFR returning after 13-15z at most sites. However, low
CIGS may continue to result in mountain top obscurations through at
least 16z. Some low-lying valleys may see fog develop tonight, with
greatest potential at KLGU. West to northwest winds will be in place
across most terminals today behind a cold front, with a return to
diurnal drainage winds this evening.
