.KEY MESSAGES...

* Another couple days of below-normal temperatures before the region
  warms up through the week.

* Monsoonal moisture increases in Arizona mid-to-late week, with
  best chances of precipitation across Mohave County.

&&

.DISCUSSION...Today through Saturday.

Dry southwest flow aloft will continue through the remainder of the
weekend into the start of next week, resulting in persistent breezy
afternoons. In addition to southwest breezes between 15 and 25 mph,
the trough across the western CONUS has allowed heights aloft to
drop, resulting in below-normal temperatures. This trough will
remain situated across the western CONUS, but a ridge of high
pressure across the southern CONUS will begin to retrograde westward
through the work week. The ridge`s westward progression will allow
heights to rise over the Desert Southwest, resulting in at-or-above
normal temperatures returning to the region as soon as Monday.
Although temperatures will rise to slightly above normal, the
HeatRisk will remain at Minor to Moderate through the week.

As the high continues to retrograde west, it will gradually start to
pull some monsoonal moisture up the Colorado River Valley. However,
the aforementioned western CONUS trough will contend with the
ridge`s westward progression, working to prevent moisture from
making it much further west than Arizona. PWATs will increase to
around 0.50" across our far southern zones on Tuesday, surging to
around 1.00" on Thursday in the lower Colorado River Valley. As a
result, slight PoPs (15-30 percent) exist for Mohave County Tuesday
through Saturday. Although gusty outflow winds will likely be the
primary threat, some storms would be capable of producing very heavy
rainfall. Elsewhere, expect dry conditions and mostly sunny skies.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Light
and variable winds this afternoon will gradually favor the southeast
as the afternoon progresses. Gusts will pick up late-afternoon as
winds veer south-southwest, with speeds between 15 and 20 kts.
Expect directional variability through the afternoon between 150 and
220. No operationally significant cloud cover through the TAF
period. Temperatures will be at-or-above 100 degrees from 21 to 02Z.

For the rest of southern Nevada, northwestern Arizona and
southeastern California...For the 18Z Forecast Package...Similar
winds expected today as the last few days, with southerly winds
picking up through the afternoon. Winds will initially favor the
southeast before shifting southwest in the latter portions of the
afternoon at Las Vegas Valley and Colorado River Valley TAF sites.
KBIH will have a persistent southeast wind until sunset and KDAG
will have gusty west winds starting late this afternoon. No
operationally significant cloud cover through the TAF period.
