.SYNOPSIS...High pressure will continue through midweek. Several
weak systems will impact northern Utah Thursday into Friday.

&&

.DISCUSSION...With temperatures running around 5 to 10 degrees
above normal levels, it continues to be a beautiful blue bird
Sunday across the region. While at one point it looked like there
would be a relatively strong system Thursday, guidance continues
to weaken this system...with total precipitation averaging from
around a trace to maybe 0.25 inches in the Bear River Range.

Early afternoon upper air and satellite analysis indicates a
broad upper level ridge across the Desert Southwest into the
southern Plains. An upper level low that has been sitting off the
southern California Coast is ejecting across southern California.
Meanwhile, an active northern stream continues to bring a series
of shortwave troughs across the northern tier of the US.

The previously mentioned upper level low will shift across Utah
through Monday...with little more than some cloud cover. As a
deeper trough approaches the Pacific Coast, stronger southwest
flow will develop across Utah Wednesday afternoon and evening.
Though 700mb flow will approach 45 kt, finding little guidance
that suggests sufficient mixing to realize wind gusts in excess of
45 mph across valley locations of western Utah Wednesday afternoon
and evening. With less than 15% chance of advisory criteria, no
products are needed. Those with remaining seasonal decorations
outdoors across southwest Utah may consider bringing them in prior
to Wednesday afternoon to avoid any damage.

By the time the trough crossing Utah, after interacting with the
northwest side of the ridge, little coherence will be left as the
system crosses Utah. As mentioned earlier, the Bear River Range
may see up to a 0.25" of water or so but everywhere south will see
substantially less, with areas south of about Provo seeing little
to no threat of precipitation.

Another shortwave trough will cross northern Utah Friday into
early Saturday. 80% or so of the members indicate at best around a
few hundredths near the Utah/Idaho border...while about 20% of
the guidance features a system that more directly impacts northern
Utah and brings around 0.10-0.20" of precipitation to northern
Utah. Given trends, suspect the 80% majority is on track.

.AVIATION...KSLC...The SLC terminal will see VFR conditions and
clear skies through the night. Northwest winds are expected to
shift back to the southeast between 03Z and 05Z.

.REST OF UTAH AND SOUTHWEST WYOMING...The airspace will see VFR
conditions through the night with mostly clear skies. Winds will
be generally light and terrain driven with the exception of
southwest Wyoming, where breezy westerly winds will continue into
the early evening before weakening.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
