Area Forecast Discussion
National Weather Service Las Vegas NV
1135 AM PDT Wed Jul 8 2026

.KEY MESSAGES...

* Dry conditions and above normal temperatures will continue through 
  the end of the week.

* Monsoonal moisture begins increasing this weekend, resulting in
  increased chances for showers and thunderstorms early next week.

&&

.DISCUSSION...Today through Wednesday.

High pressure will gradually build into the area over the next few 
days from the west. The center of the high will push across Nevada 
on Friday night and then move near the Four Corners on Saturday 
which will begin to open the door to monsoonal moisture. More on 
that later. In the meantime, above normal temperatures will be the 
rule. We will be very close to or at 110 for high temperatures in 
Las Vegas through Saturday. We have not hit 110 yet this year and on 
average we reach that level about 10 times per year.

As the moisture builds into the region aloft, the chance of 
thunderstorms will also increase. With isolated thunderstorms as 
early as Sunday although instability, if any will be quite limited, 
and then more scattered coverage on Monday. The moisture increase 
will mainly be in the mid and upper levels initially and that will 
keep the main concerns with any thunderstorms being dry lightning 
and strong and gusty winds. Moisture will likely be with us for much 
of the week and any additional details with respect to thunderstorm 
activity will become better resolved over the next few days. The 
increased moisture will however, reduce our high temperatures by 
several degrees.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds
will shift to the southwest early in the forecast period, 
increasing to around 10-15KT with gusts to 20-25KT through the 
afternoon. Gusts are expected to diminish quickly after sunset 
with the loss of heating, with winds becoming light and variable 
by daybreak. Following a similar pattern on Thursday, winds shift 
to the southeast by mid-morning, then veer to the southwest during
the afternoon with another round of gusts to 20-25KT expected 
thereafter. VFR conditions with clear skies will continue, with a 
high temperature of 109F and temperatures exceeding 100F through 
04Z this evening, and again on Thursday after 18Z.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Winds across much of
the region will shift to the south- southwest this afternoon, 
with gusts to 20-25KT common through sunset. An exception to this 
will be in the northern Owens Valley including KBIH, where winds 
generally follow daily patterns until mid-afternoon, when a push 
of westerly winds around 10-15KT is expected through sunset, 
followed by a northeasterly shift before winds become light and 
settle out of the northwest overnight. At KDAG in the western 
Mojave Desert, winds generally remain westerly, with periodic 
gusts to around 25KT through midnight. Tonight, winds become 
lighter across the area, with another round of elevated/gusty 
southerly to southwesterly winds developing late in the period. 
VFR conditions with no operationally significant cloud cover will 
continue.
