.KEY MESSAGES...

* Smoke from nearby fires will result in hazy skies at times through
  Saturday, but significant or widespread smoke impacts near the
  surface are not expected.

* Hot and dry conditions will continue through the weekend with
  temperatures peaking Monday as ridging persists across the region.

* Monsoon moisture makes a possible return mid to late next week
  along with a drop in temperatures.

.DISCUSSION...Today through the Middle of Next Week...
High pressure over the region will allow temperatures to climb
through the weekend and into early next week with temperatures
peaking Monday. HeatRisk is mostly in the Moderate (Level 2)
Saturday, but we are starting to see more isolated pockets of Major
(Level 3) on Sunday. HeatRisk on Monday shows the greatest coverage
of Major (Level 3) with temperatures running about 5-8 degrees above
normal; however, these temperatures will still fall a few degrees
shy of record values. At this point, decided to hold off on any Heat
Warnings, but will continue to monitor.

Hazy skies are expected over the next couple of days as various
fires burn across the region combined with generally light winds
aloft. The Gothic Fire located in central Nye County is the largest
fire and has been responsible for most of our hazy conditions. So
far today, smoke production has been much less than previous days,
but that will need to be watched this afternoon if another
significant plume gets generated.

The ridge will slowly retreat and weaken next week after Monday.
Temperatures will cool off a bit each day in response. In addition,
on Tuesday, a slight increase in moisture is expected. This moisture
will not result in any precipitation but will help cool temperatures
and also reduce any fire danger due to extremely dry conditions. On
Wednesday, high temperatures will have fallen back closer to normal
for this time of the year. Any precipitation chance is now not
expected until Thursday or later when better moisture and an
easterly shortwave could bring low chances for precipitation.
