.DISCUSSION...Today through Friday.

Hazy skies are expected at times 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 the hazy conditions
through much of Southern Nevada the past few days. This should
continue today though the smoke plume is less robust on HRRR smoke
compared to previous days. In addition, new fires in north-central
Arizona may also produce smoke aloft with the HRRR showing smoke
advecting through Mohave County at times tonight and Saturday.
Smoke continues to be aloft with minimal near surface or visibility
reductions noted on the HRRR and probabilistic models.

Above normal temperatures will continue as high pressure will
continue to build over the region through Monday. The hottest days
will be Sunday and Monday when heights reach +1.0 to +1.5 sigmas.
High temperatures will climb 6-8 degrees above normal Sunday and
Monday. Widespread Moderate (Level 2 or 4) HeatRisk is forecasted
this weekend. On Monday, the HeatRisk forecast continues to
fluctuate and now the area of Major (Level 3 of 4) HeatRisk is more
widespread from previous forecasts in the mid to low elevations.
Will continue to monitor temperatures and trends as a heat product
may be needed for Monday.

The ridge will slowly retreat and weaken after Monday. Temperatures
will cool off each day in response starting Tuesday. 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 closer to normal and
expected to remain near normal through the rest of the week. Any
precipitation chance is now not expected until Thursday or later
when better moisture and an weak shortwave could bring low chances
for precipitation. From the previous forecast, late week moisture
increases and precipitation chances have not changed significantly.

decrease expected during the late-morning and afternoon. Breezy
southerly winds expected along the Colorado River Valley with
