.DISCUSSION...Little in the way of impactful weather over the
forecast area for at least the next 5 to 6 days as high pressure
will gradually reestablish over the Great Basin region. A weak
shortwave trough, already noted over a portion of northwest Utah,
will continue to translate through the area over the next 12-24
hours, with the biggest influence on sensible weather being a
slight drop in daytime high temperatures. That said, highs will
remain solidly above normal (+10F) for this time of year. A weak
pressure gradient is anticipated to develop across southern Utah
this afternoon/ evening as a result of weak baroclinic zone
forming from the aforementioned shortwave, leading to breezy
northerly canyon winds (30-40 mph) between St. George and Cedar
City.

Following the passage of the shortwave trough, high pressure will
strengthen day after day through at least Thursday as a ridge
intensifies over the western U.S. Thursday through Sunday there is
some disagreement amongst models on how a developing offshore low
will evolve as it interacts with the mid-latitudes. Should not
note much change in the day to day weather as this low dances to
our southwest, however, the evolution of this low may influence
our next potential weather maker as we move into the late weekend/
early next week timeframe. Ensemble guidance (12Z) notes a
favoring towards a pattern change by the late Sunday/ early Monday
period, with around 30% of ensemble members supporting widespread
precipitation across Utah and southwest Wyoming. Again, will need
to watch how the aforementioned offshore low is going to evolve,
which will ultimately have some influence on how this next trough
may evolve.

Big picture remains the same... dry, relatively stable conditions
persist across the forecast area until early next week. Monday
forward, conditions could become wet and unsettled as the
persistent high pressure looks for an avenue to break down.

.AVIATION...KSLC...The SLC terminal will see VFR conditions through
the morning with some high clouds. Southerly winds are expected to
become predominately northwesterly between 17Z and 19Z, though some
periods of light and variable winds will continue through the early
morning.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions are expected
across the airspace this morning with some high clouds and generally
light and terrain driven winds. There is a low (20 percent) chance
of fog between 10Z and 15Z at LGU which would result in periods of
IFR conditions.
