Area Forecast Discussion
National Weather Service Salt Lake City UT
331 AM MDT Fri Aug 23 2024

.SYNOPSIS...Persistent moisture will allow for scattered to
numerous thunderstorms in the east today while dry and windy
conditions are forecast across the west. A cold front will sweep
in over the weekend, bringing cooler temperatures for much of the
state.

&&

.SHORT TERM (Through 12Z/6AM Sunday)...Just as anticipated for the
overnight hours, scattered showers and isolated thunderstorms are
continuing across southern Utah. A general progression to the
northeast toward the I-70 corridor is anticipated through the
morning hours as an overall complex of the same weather; scattered
showers and isolated thunderstorms.

Beginning this afternoon, risk for scattered to numerous showers
and thunderstorms are forecast to increase for areas east of
I-15. Greatest risks associated with these thunderstorms will be
heavy rains, gusty winds and small hail. An area to focus on with
the greatest threat for gusty winds/thunderstorm activity is noted
across the Bear River Valley and Wasatch Back in the afternoon
hours. The Bear River area is noting a 90% risk for wind gusts in
excess of 40 mph and 10% risk for 60 mph gusts. This would include
recreators on Bear Lake.

While risk for flash flooding has, as a whole, decreased compared to
yesterday there is still plenty of moisture available across
Utah. PW values continue around 1.0 inches in the south with
around 0.7 inches across the much of the rest of the state. While
mean flow of thunderstorms today is expected to be around 30 mph
(quite fast), training of showers and thunderstorms is still very
much a possibility. As a result, there will remain the possibility
of flash flooding in vulnerable areas such as in slot canyons,
normally dry washes, creeks and streams, recent burn scars, and
other low-lying and flood-prone locations.

The area that is not expected to have much moisture at all is across
western Utah.  An area of low pressure to our northwest is incurring
a very strong pressure gradient across California, Nevada and into
western Utah. Southerly sustained winds between 25 and 35 mph
will result across the western half of the state which is forecast
to continue through Saturday evening. Winds of this magnitude are
expected to spread eastward during the day Saturday as a cold
front tracks trough. Probabilities for wind gusts to exceed 45 mph
have remained high this afternoon across western Utah and as
such, a wind advisory will go into effect for Eastern Box Elder
County, the Great Salt Lake Desert/Mountains, Tooele and Rush
Valleys, Southwest Utah and western Millard/Juab counties.

As the aforementioned cold front makes it way eastward Saturday,
winds have only increased in likelihood to exceed wind advisory
thresholds for Saturday. Wind advisories will go into effect for
the northern Wasatch Front and Salt Lake Valley Saturday as a
result, while wind advisories continue Saturday for the above
mentioned areas in the west as well.

The cold front is forecast to stalling across the state on Sunday
becoming stationary. Behind this boundary, much colder air will
filter in. A very 'fall- like' feeling is coming your way, especially
the latter half of the weekend. Saturday's temperatures, while
cooler, will feel nothing like fall if you're comparing them to
Sunday's forecast temperatures!

.LONG TERM (After 12Z/6AM Sunday)...The period begins with an
anomalously deep trough over the Northern Rockies and Great Basin.
With the trough axis along the Nevada/Utah state line, enough
residual moisture will be present to support a chance for afternoon
showers and thunderstorms over southeast Utah, with some potential
over the Uinta Mountains as well, where snow level could dip to
around 11 thousand feet. With dry air in place over extreme
southwest Utah, some potential will still exist for critical fire
weather conditions, but even 75th percentile winds remain just below
criteria.

Generally dry weather is expected on Monday and Tuesday, as roughly
90 percent of ensemble solutions favor a generally flat ridge over
the Great Basin, with an associated dry westerly flow. The remaining
10 percent suggest a more amplified ridge with some returning mid
level moisture.

Greater uncertainty emerges for Wednesday, and especially Thursday.
Roughly 75 percent of ensemble solutions favor yet another trough
sweeping across the Northern Rockies into the Northern Plains, with
the remaining 25 percent offering a somewhat deeper and slower
solution, with moisture advecting into southern Utah.  Given
uncertainty, low chances (20-30 percent)for precipitation over
southern Utah on Wednesday and Thursday seem appropriate.

&&

.AVIATION...KSLC...VFR conditions will persist at the KSLC
terminal through the TAF period.  Enhanced southeast drainage winds
will become southerly and increase through the day, with gusts up to
35 knots during the afternoon and early evening.  Convection in the
KSLC vicinity will be possible from roughly 19Z through 23Z, with a
brief period of MVFR conditions due to rain.  Additionally, gusty
and erratic winds will be possible with the thunderstorms and
associated outflow boundaries.

.REST OF UTAH AND SOUTHWEST WYOMING...Showers will be
scattered about southeast Utah during the morning hours, with
associated areas of IFR ceilings and visibilities. Scattered showers
and thunderstorms will develop across Utah this afternoon, primarily
east and south of a KLGU to just east of KSGU line.  A period of
MVFR conditions and gusty and erratic winds will be possible with
the storms.  Additionally, outflow boundaries may create brief wind
shifts.  Strong southerly winds will persist into the
evening.

&&

.FIRE WEATHER...The region remains under the influence of two weather
systems today. An area of low pressure to our northwest is
incurring a very strong pressure gradient across California,
Nevada and into western Utah. Southerly winds sustained between 25
and 35 mph will result across the western half of the state by
this afternoon and continue through Saturday evening. With
critically dry conditions forecast for a chunk of the fire weather
zones, there is high risk for fire potential due to these dry and
windy conditions both Friday and Saturday. Winds are expected to
decrease some after sunset and into the overnight hours Friday
night. All of that considered, Red Flag Warnings will thusly
continue.

Across eastern (and southern) Utah zones, a much wetter scenario
will play out. There is little fire risk here outside of gusty
outflow winds that may result from thunderstorms that develop. In
fact, wetting rains for the eastern half of the state today range
anywhere from 40 to 80 percent. Chances for precipitation decrease
quite a bit for Saturday in these areas but isolated showers and
thunderstorms are still forecast.

By Sunday, wind speeds are forecast to diminish across these areas
and allow the threat for fire spread to decrease. Additionally,
temperatures will cool below seasonal normals behind the passage of
a cold front earlier in the weekend. These cooler conditions will be
short lived though as they will begin to climb again early next
week.

&&
