.SYNOPSIS...Hot, dry and breezy conditions will continue to impact
the region through early part of the week. Heavy wildfire smoke
is expected across southeastern Utah and in the Richfield vicinity
through at least late Monday.

&&

.SHORT TERM (THROUGH 12Z TUESDAY)...A warm and dry southwesterly
flow aloft will remain in place tonight and tomorrow. Very deep
afternoon mixing has allowed breezy conditions to continue, with
winds overperforming again compared to models. In general, over
the past few days, winds have been verifying closer to the
75th-90th percentile of the NBM. Winds today are slightly weaker
compared to yesterday, and tomorrow should be similar to today
across western Utah while decreasing across eastern Utah. The
winds and dry conditions will continue to bring critical fire
weather conditions to a least southwestern Utah tomorrow.

Smoke remains a concern as wildfires remain active given the dry
and breezy conditions. The southwest flow has continued to
transport smoke from the Dragon Bravo Fire into southeast Utah,
while smoke from the Monroe Canyon Fire continues to impact
portions of central Utah, leading to reduced visibilities and poor
air quality impacting sensitive groups.

.LONG TERM (AFTER 12Z TUESDAY), Issued 403 AM MDT...
Dry and hot conditions will continue through at least Tuesday. By
Wednesday, a subset of the guidance (around 50% of ensemble
members) bring an increase in mid-level moisture to portions of
central and eastern Utah. This increases a bit further Thursday
before drying back out again Friday. Given the best moisture
remains east of the CWA, expect the main impact will be high-based
showers and thunderstorms and gusty, microburst winds with a
small humidity improvement rather than heavy rain or flash
flooding.

Unfortunately, nearly all members keep western Utah in a hot, dry
pattern, likely exasperating fuel conditions and further
increasing evaporative demand.

&&

.AVIATION...KSLC...VFR conditions prevail through the remainder of
the TAF period. Southerly winds with gusts to around 25 kts will
continue at the terminal through around 03z, becoming lighter out of
the southeast thereafter.

.REST OF UTAH AND SOUTHWEST WYOMING...Gusty southerly to
southwesterly winds continue for all regional terminals this
afternoon and evening, with widespread gusts to 20-25 kts. VFR
conditions prevail for most sites across the airspace, though heavy
surface smoke may lead to MVFR/IFR CIG and VIS reductions for
terminals in the vicinity or downwind of the Monroe Canyon and
Dragon Bravo fires each afternoon and evening through at least
Monday. Increased vertically integrated smoke concentrations are
also expected across the eastern half of Utah through at least
Monday, resulting in hazy skies and slantwise visibility reductions.

&&

.FIRE WEATHER...A warm and dry southwesterly flow will remain in
place over the area through the early part of the week. Low
humidities down to the single digits with poor overnight
recoveries will continue to be common in many areas. While winds
will trend slightly weaker tomorrow, they will remain breezy,
especially across portions of western and southwest Utah.
Critical fire weather conditions due to a combination of low
humidities and gusty winds are expected again tomorrow, but will
likely become more confined to southwest Utah. Winds will then
continue to decrease slightly for Tuesday, then increase again on
Wednesday, which could bring another round of critical fire
weather conditions.

Moisture is still expected to spread into the area from the
southeast for the middle through latter part of the week.
Relative humidities across the spine of Utah and eastern valleys
should trend higher as a result, but this moisture is unlikely to
spread much into western Utah. Additionally, this moisture
currently does not look to be very signficiant. As a result,
high-based showers with dry thunderstorms and gusty outflow winds
will be more likely than any appreciable wetting rain.
