.DISCUSSION, Issued 1000 PM MDT Fri Oct 23 2026...
The piece of a broad Pacific storm system that moved
through Utah and southwest Wyoming late night is moving into
Canada this evening as the southern branch moves into the Desert
Southwest. A few showers linger near the Utah/Idaho border in
association with the first piece, but these are rapidly
diminishing as the shortwave continues north. Temperatures have
been on the cool side today, with maxes running 5-10F below
seasonal normals.

The southern branch of the low is on track to slowly move across
Arizona on Saturday before turning to the northwest and moving
into Colorado on Saturday. This will keep moisture and instability
over southern Utah, southeast Utah in particularly, resulting in
the development of scattered showers and thunderstorms throughout
the day. Overall coverage and duration will be much less than what
we saw the past few days, but can`t rule out some areas of flash
flooding. Once the system starts tracking northeast, the threat of
showers will spread across eastern Utah, with the showers
primarily focused over the higher terrain east of I-15.

Weak ridging is then expected to move over Utah during the day on
Monday, bringing dry conditions with maxes near seasonal normals.
However, the storm track over the Pacific coast will remain open
(and remain that way throughout the week) in the absence of a
Pacific ridge to block incoming systems. Therefore, confidence is
high that next week will be wetter than average as a series of
storm systems move onshore and track east. However, there remains
a good about of ensemble spread with regard to the timing and
track of any particular storm system, and therefore confidence
remains low with regard to the details about potential impacts for
Utah and southwest Wyoming.

.AVIATION...

KSLC...Northwesterly winds around 6-10kts will persist through the
day, transitioning to light and southeasterly after ~02-03z. VFR
conditions will prevail.

REST OF UTAH AND SOUTHWEST WYOMING...Scattered showers and isolated
thunderstorms will begin to develop after ~16z this morning across
southern and eastern Utah (largely south of KPUC and east of I-15).
These showers will likely last through the afternoon, largely
diminishing by 02z with some isolated shower activity lingering
overnight. Storms may be capable of producing gusty and erratic
outflow winds. Otherwise, winds, while favoring a northwesterly
direction during the day, will largely follow diurnal trends. VFR
conditions will persist as a whole, however if cloud cover Saturday
night is less than currently forecast, isolated areas of fog may
develop (highest chances at KLGU...20% chance).
