.SYNOPSIS...A very dry and seasonably warm airmass will remain
over the area over the next several days.

&&

.SHORT TERM (Through 12Z/6AM Sunday)...The upper trough that was
over the Great Basin yesterday is lifting northward into Idaho and
Montana this morning. High pressure centered over Colorado and New
Mexico is keeping Utah and southwest Wyoming under a dry southwest
flow aloft. Seeing slightly less dry conditions over northwest and
southeast Utah where a small amount of moisture has intruded, but
conditions otherwise remain extremely dry. In the wake of the
trough, temperatures will run near normal for this time of year.

Winds will slowly weaken into the weekend as the ridge axis
gradually makes its way west, with the flow aloft subtly veering.
A weak and disorganized trough will slide through the flow Friday
night through Saturday bringing a minor increase in instability,
but conditions will remain quite dry. Cannot rule out some
afternoon/evening high based showers and thunderstorms. They will
produce little if any rainfall, with gusty winds being the main
threat with any storms that develop.

.LONG TERM (After 12Z/6AM Sunday)...The forecast area will be under
generally zonal flow on Sunday, resulting in a nearly quintessential
August day. Expect temperatures near climatological normals, typical
afternoon breezes, and dry conditions across Utah and southwest
Wyoming.

This zonal flow will be brief, with ensembles strongly supportive of
a shortwave trough digging into the Great Basin on Monday. This
system is expected to introduce increased southwesterly flow aloft,
which will result in gusty afternoon winds to 30 mph and very dry
conditions across the region, especially across central, southern,
and eastern portions of the Beehive State. These conditions will
lead to heightened fire weather concerns on Monday.

The aforementioned trough lifts northeastward out of the region
Tuesday, with a stout ridge filling in across the southwestern US in
its place. Moisture riding up the western periphery of this ridge on
Tuesday into Wednesday will promote increased chances for afternoon
showers and thunderstorms, mainly across southern Utah. Ensemble
cluster guidance indicates this ridging pattern will remain a
dominant feature through the end of the week.

&&

.AVIATION...KSLC...VFR conditions to prevail through the
period. Light southeasterly winds continue this morning ahead of a
wind shift to the northwest between 18 and 19z. Expect breezy
northwesterly winds to continue through around 04z, becoming light
out of the southeast thereafter.

.REST OF UTAH AND SOUTHWEST WYOMING...Dry conditions across the
airspace will maintain VFR conditions for all regional terminals
throughout the period. Winds remain generally light and terrain
driven this morning, with typical breezes developing this
afternoon. Some stronger gusts to 20-25 kts are possible this
afternoon for southern Utah terminals.

&&

.FIRE WEATHER...High pressure remains centered over Colorado and New
Mexico, keeping Utah under a very dry southwest flow. Winds will
relax a bit today into the weekend with a Great Basin trough
exiting the area, but winds will still be strong enough over the
mountains of central and southern Utah to produce areas of
critical fire weather conditions. Disturbances moving in the
southwest flow will allow for a few high based afternoon storms
capable of producing gusty winds, primarily over northwest and
southeast Utah where the airmass is not quite as dry. Another
trough is expected to move into the Great Basin by Monday,
resulting in increasingly breezy southwest flow and increasing the
threat of critical fire weather conditions.

.SLC WATCHES/WARNINGS/ADVISORIES...
