.SYNOPSIS...Northwesterly flow will maintain a warm and dry
airmass across the region through Monday. High pressure will then
bring a warming trend heading into midweek. Beginning Wednesday,
an increase in moisture will bring a chance for thunderstorms.

&&

.SHORT TERM (Through 12Z Tuesday...Northwesterly flow continues
across the region this afternoon. Strong high pressure will
gradually shift eastward into the Southwest through the short
term forecast period. This will bring gradually warming
temperatures and dry conditions to the Beehive State.

Little impact from sensible weather, except to those vulnerable to
heat issues...by Monday afternoon, many locations across the
Wasatch Front will surge into the 90s once again.

.LONG TERM (After 12Z Tuesday), Issued 412 AM MDT... At the
beginning of the long term portion of the forecast on Tuesday,
deterministic and ensemble solutions are in good agreement with
their respective depictions of a broad ridge of high pressure
centered over the Western Great Basin, with the expectation that
the ridge will crest overhead on Wednesday. As a result, expect a
continued warming trend through Wednesday, when temperatures will
rebound to 5F-10F above normal for mid-August, before leveling off
and falling slowly through the rest of the week. There is good
consensus among the model solution space showing another Northern
Rockies trough grazing northern Utah late Wednesday into Thursday.
It appears there will be just enough large scale ascent and
meager moisture associated with this trough to aid in the
development of some high-based convection, with the main risk
being gusty/erratic microburst wind and isolated lightning
Wednesday afternoon and evening across most of the area.

Heading towards the Thursday-Friday timeframe, general model
consensus suggests that a longwave trough will develop over the
western CONUS, aiding in the establishment of broad S-SW flow
across Utah/SW Wyoming during this period. Ensemble PWAT anomalies
push into the slightly above normal range for the time of year in
the late Thursday-Saturday timeframe, suggesting a slight
glancing brush of monsoonal moisture working into the area. It`s
too early to say if this moisture will manifest itself in the form
of extensive mid- level cloudiness with a few showers, or a few
organized thunderstorms capable of localized, briefly heavy
rainfall.

&&

.AVIATION...KSLC...VFR conditions prevail at the KSLC terminal
through the period, with mostly clear skies other than a few
passing high clouds. Generally light northwesterly breezes
continue through roughly 04-05z, becoming predominantly
southeasterly thereafter. A weak northerly pressure gradient in
place may lead to periods of variable winds during the early
morning hours as it interacts with local drainage winds.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions prevail for
all regional terminals through the remainder of the period. Skies
remain generally clear outside of some scattered high clouds
across southern Utah this afternoon, but are expected to clear
overnight into Monday morning. Winds are expected to remain
generally light and terrain-driven for all terminals through the
period.


&&

.FIRE WEATHER...Northwesterly flow continues across the region
this afternoon. Locally critical fire weather conditions are being
reported across eastern Utah, from roughly SR-6 southward to the
Grand Staircase. While northwesterly winds will gradually decrease
Monday, localized critical fire weather conditions will be
possible in a similar area.

Expect gradual warming as high pressure moves across the region
through midweek. By Tuesday night, recoveries will once again fall
into the poor range, with very dry daytime humidities. As mid-
level moisture increases across southern Utah Wednesday into
Thursday, lightning after an extended dry period will increase in
probability. Thunderstorms will trend wetter Friday...if the mid-
level moisture can remain in place.

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