.KEY MESSAGES...

* Hazardous heat will continue into early next week.

* Monsoon moisture returns late next week.

&&

.DISCUSSION...through Friday.

Extreme temperatures will continue through the weekend as high
pressure remains parked overhead. Temperatures will peak around 5 to
10 degrees above normal, with places like the Las Vegas Valley
between 110 and 115 degrees, Death Valley 120 to 125, and the
Colorado River Valley around 115 to 120 degrees. Daily and monthly
records are in jeopardy for a number of our climate sites in the
coming days. These temperatures will yield widespread Major-to-
Extreme HeatRisk (Levels 3 and 4 of 4, respectively) over the
weekend and into early next week. A shortwave trough will push into
the Pacific Northwest over the weekend, which will help to suppress
the high slightly and lower heights early next week. This won`t
bring much relief, as temperatures only get knocked down a couple of
degrees through much of next week.

As the shortwave exits the region toward the middle to end of next
week, the high will re-estabilish itself over the Desert Southwest.
The placement of the high center will likely dictate if we are able
to tap into some monsoonal moisture. So far, the ensembles have been
fairly consistent in bringing an increase in moisture mid to late
next week, with thunderstorm probabilities mainly confined to Mohave
County; however, by next weekend, those chances will likely start to
expand northward.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...
Light to moderate southeast winds  with gusts around 16 kts last

increase in the late morning becoming southeasterly with around 15
kt gusts. Winds will shift in the late afternoon, becoming
southwesterly and then easing in the mid evening on Saturday. Mostly
clear skies are expected through the TAF period.

California...For the 00Z Forecast Package...Moderate to breezy winds
continue to affect most of the region into the mid evening to early
night before reducing. The exception will be KDAG which will see
gusts arrive in the evening, peaking closer to 20 kts, and not
reducing until the late night. Winds don`t look to increase again
until the late morning and early afternoon on Saturday. Mostly clear
skies are expected through the TAF period.
