  Mojave Desert. Hotter than normal temperatures will continue
  through next week.

* Convective activity will be limited to northwestern Arizona
  through next week.

.DISCUSSION...through Saturday.

Widespread Major (Level 3 of 4) to Extreme (Level 4 of 4) HeatRisk
will continue through Monday as temperatures continue to run around
5 to 10 degrees hotter than normal with little to no overnight
relief in places like Las Vegas, Laughlin, Lake Havasu City, and
Death Valley. Temperatures will decrease a few degrees on Tuesday
and Wednesday as the upper-level ridge responsible for the recent
heat shifts off to the east. This ridge will retrograde back to the
west, moving directly overhead later this week. As the ridge moves
back overhead, we will see temperatures take back off as we close
out July and begin August with temperatures 7 to 10 degrees hotter
than normal. As temperatures take back off, we will see widespread
Major HeatRisk across our entire forecast area on Friday, with
widespread Major-to-Extreme HeatRisk over the weekend.

Moisture, driven by outflow winds from storms in Arizona, will
continue to work its way up the Colorado River Valley this morning
and afternoon, spilling into southern Nevada and northwestern
Arizona. This moisture will help to fuel isolated afternoon
convection, with a 15 to 25% chance of precipitation in the higher
terrain of Mohave County and the higher terrain surrounding the
Colorado River Valley. Precipitation chances will decrease on Monday
as moisture decreases. As the ridge shifts back to the east, we will
see a brief period of southeasterly winds aloft, which will result
in a slight uptick in moisture on Tuesday. This slight uptick in
moisture will bring a 15 to 20% chance of showers and thunderstorms
to far eastern Mohave County on Tuesday afternoon. Things will dry
out across the region during the second half of the week as the
ridge begins to retrograde back overhead.

For the rest of southern Nevada, northwest Arizona and southeast

late morning. Breezy southerly to westerly winds will pick up this
afternoon with 15 to 25 knot wind gusts expected. Winds will
decrease during the evening hours, favoring typical diurnal
directional trends. Isolated convection will be possible in
