Area Forecast Discussion
National Weather Service Salt Lake City UT
939 PM MDT SAT AUG 27 2016

.SYNOPSIS...An upper low over Arizona will move east to the four
corners tonight. High pressure will move in tomorrow behind this
system, allowing for a drying and warming trend for the first part
of the upcoming week.

&&

.DISCUSSION...An upper low is centered near the NV/AZ border this
evening. A few showers continue to persist over southern Utah on
the back side of this weakening system, but have diminished
significantly with the loss of daytime heating. The low will
continue east overnight, keeping a limited threat of showers over
southeast Utah. Updated the forecast earlier to lower POPs and
decrease cloud cover tonight. No additional updates planned.

As the storm system exits, high pressure will move into the
forecast area behind it for the first part of the upcoming week.
This will result in a warming and drying trend, though a few
showers and thunderstorms may still pop up over the higher
terrain. GFS/EC both indicate increasingly southerly flow by
midweek as a broad storm system approaches the Pacific coast. GFS
indicates a surge in moisture while the EC would keep conditions a
bit drier. Maxes should run a few degrees above climo for most
locations by the middle of the week.

&&

.AVIATION...The SLC terminal will see VFR conditions with mostly
clear skies through the night. Southerly winds are expected
through the overnight hours.

&&

.FIRE WEATHER....An upper low near the NV/AZ is keeping a few
showers and thunderstorms going over southern Utah overnight. This
system will track east toward the four corners through the night.
Behind this system, high pressure will build over the forecast
area for the first part of the week, allowing for a drying and
warming trend with relatively light winds. A Pacific storm system
is expected to approach the coast by mid-week resulting in
increasing winds and moisture over the district.

&&

.SLC Watches/Warnings/Advisories...
UT...None.
WY...None.
