Area Forecast Discussion

.SYNOPSIS...Broad low pressure system will continue to yield
unsettled weather through the evening. While a weak system may
graze the area late Monday, high pressure is otherwise expected to
largely impart a drying and warming trend.

&&

.SHORT TERM (Through 12Z/6AM Sunday)...A large low pressure system
is centered over Arizona this morning, with an ejecting wave from
this system currently over northern Utah, producing some very
light precipitation. The northern Utah precipitation will diminish
later this morning. The low is on track to continue southeastward
away from the area today and tonight. Still, enough moisture and
instability will linger to combine with daytime heating to produce
another round of showers, primarily focused over the higher
terrain. Associated higher terrain accumulations will be generally
light, but cannot rule out a quick inch or two with a heavier
cell. With a relatively cool airmass in place, high temperatures
today are expected to run 5-10F below seasonal normals.

Behind the exiting low, high pressure will build into the area for
the weekend. However, the track of the low will keep an E/NE
gradient over Utah and southwest Wyoming tonight into early
Saturday morning, resulting in some enhanced gap/canyon winds for
prone areas of both the Wasatch Front and lower Washington County.
Gradients should not be notably strong, however, and associated
cold advection is weak at best, limiting the potential for a
downslope wind event of significance. While only a few degrees of
warming is anticipated on Saturday, more substantial warming is
anticipated in the long term period as high pressure continues to
build.

.LONG TERM (After 12Z/6AM Sunday)...Little changes to the extended
forecast with recent guidance, as we remain on track for persistent
ridging to dominate the pattern through late next week.

Ensemble clusters are in strong support for a high-amplitude ridge
currently anchored off the west coast to nudge inland on Sunday.
This pattern will support large-scale subsidence across the region,
yielding drier and milder conditions on Sunday. Temperatures are
expected to gradually warm back above seasonal averages into early
next week, with highs on Monday trending around 10 degrees above
average. A weak shortwave trough is slated to brush by to our north
late Monday into Tuesday, yielding a slight uptick in PoPs across
far northern Utah and southwest Wyoming through this period. Any
precipitation accumulation will be light, generally only a few
hundredths of an inch. A brief pause in the warming trend is also
expected as a result of this passing trough, but high pressure
quickly redeveloping over the western US keeps this pause brief.
Ensemble clusters show a bit of variability in the strength of high
pressure over the region come late next week, but the overall
consensus shows a high probability that temperatures remain well
above average.

.AVIATION...KSLC...Lake enhanced rain showers are ongoing early this
morning in the vicinity of the terminal, resulting in continued
mountain obscuration from lowered CIGS. Showers are expected to
gradually taper mid-to-late morning, before scattered rain showers
redevelop once again this afternoon, roughly between 20-03z. Light
northwesterly winds prevail this morning, increasing roughly after
18z with gusts around 20 knots into the evening.

.REST OF UTAH AND SOUTHWEST WYOMING...Other than light, lake
enhanced showers south of the Great Salt Lake this morning,
conditions are expected to remain dry areawide through roughly 18z.
Scattered showers are expected to increase in coverage across Utah
and southwest Wyoming thereafter, with some isolated thunderstorms
possible through 03z. Any storms that develop will be capable of
producing brief heavy rainfall, gusty and erratic outflow winds, and
mountain obscuration. Otherwise, light winds this morning are
expected to increase out of the north for all regional terminals
this afternoon, with winds remaining elevated across southwest Utah
into Saturday.

.SLC WATCHES/WARNINGS/ADVISORIES...
