.KEY MESSAGES...

- Scattered showers will return to southeast Utah on Saturday and
  develop across eastern Utah on Sunday as a Pacific low moves
  across the Desert Southwest.

- A series of storm systems will move through Utah and southwest
  Wyoming next week, resulting in periods of cooler weather as
  temperatures stay near or just below seasonal normals.
  Confidence is low on the timing and other details of specific
  systems.

.DISCUSSION...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...VFR conditions prevail through the TAF period at KSLC.
Periods of variable winds may occur overnight into Saturday morning;
overall, winds remain generally light out the northwest through
Saturday,

REST OF UTAH AND SOUTHWEST WYOMING...Rain showers are expected to
continue moving east along the ID border through this evening,
resulting in terrain obscuration around KLGU. Otherwise, VFR
conditions prevail for all regional terminals through Saturday with
northerly flow developing across most of the airspace overnight.
