.SYNOPSIS...Unsettled conditions will continue into the early
evening, focused over central and southern Utah. High pressure
will bring drier and warmer conditions over the weekend and into
early next week.

&&

.SHORT TERM (Through 12Z/6AM Sunday)...Two troughs diverged over
the state of Utah, with lingering moisture and instability from
both. Best moisture and jet support are over southern and eastern
Utah this afternoon, where scattered convection has developed.
Some have the structure of strong to severe storms, and others
have produced heavy rain capable of flash flooding. These threats
will continue into the early evening before convection diminishes
with the loss of daytime heating.

With one trough moving off the California coast and the other
shifting into the central United States, a Rex Block pattern will
develop over the region beginning Saturday, with dry high pressure
building over Utah and southwest Wyoming. Cannot rule out a few
afternoon showers over the higher terrain for Saturday,
particularly over southern Utah, but conditions overall will be
much more tranquil. Temperatures will also be noticeably warming,
with maxes running a couple of degrees above climo over southern
Utah and 5-7F above seasonal normals for northern Utah and
southwest Wyoming.

.LONG TERM (After 12Z/6AM Sunday), Issued 411 AM MDT... An upper-
level ridge passing across the Great Basin will result in overall
subsidence and warming temperatures through at least early
Monday, with Sunday`s high temperatures expected to reach the
upper-80s/low-90s across most valleys and near 100F in St. George.
While conditions will be mostly dry, a passing weak closed low
across southern Utah will bring low chances for
showers/thunderstorms across the southern mountains on Monday
afternoon, which may be capable of gusty outflow winds given a dry
sub-cloud layer.

Moisture will start to increase across the area on Tuesday with
an approaching shortwave trough, though chances for showers and
thunderstorms remain low and likely confined to higher terrain.
These chances will increase across northern Utah/southwest Wyoming
on Wednesday as this shortwave trough grazes northern Utah.
Although confidence has increased with the track and depth of this
shortwave, there still remains plenty of spread with moisture
availability across the north, still somewhere between 0.6-0.8" of
PWAT. This will ultimately determine the coverage of storms as
well as any chances for localized heavy rainfall. Modestly active
weather may return again next Friday with another shortwave
trough, though these details still remain fuzzy at this time.

&&

.AVIATION...KSLC...VFR conditions will prevail for the KSLC terminal
through the period. Dry and sunny conditions will continue this
evening with light northerly winds transitioning to light southerly
flow overnight.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will persist
for the northern half of the airspace through the period as dry and
sunny weather continues with light and diurnally driven winds. VFR
conditions with brief periods of MVFR/IFR this afternoon as
scattered convection continues through sunset with gusty outflow
winds possible. Afterwards, drier air and clearing skies will move
into the area with light and variable winds.

&&

.FIRE WEATHER...Anomalous moisture will linger on Friday, resulting
in a similar evolution of showers and thunderstorms to that of
the last several days. Activity will increase late morning on
through the day, with a few thunderstorms capable of frequent
lightning and periods of heavy rain. With overall moisture a bit
less than previous days, total coverage will be slightly lower,
but convection will be slightly higher based in nature and also
more capable of producing some gusty and erratic outflow winds. In
general, activity will favor central and southern Utah. Moisture
further decreases on Saturday, and weather features otherwise
responsible for the active pattern start to shift away from the
region. As such, expect drier conditions across the area along
with rising temperatures. Mild and largely dry conditions then
persist into next week.
