Area Forecast Discussion
National Weather Service Las Vegas NV
430 PM 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 00Z Forecast Package...South 
to Southwest winds 10-15 kts with gusts 20-25 kts to continue 
through around 03z. 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 SSE-S briefly mid-morning, then veer to the S-SSW 
during the afternoon with another round of gusts to 20-25KT expected 
thereafter. VFR conditions with clear skies through the period. 
Expect temperatures at or above 100 degrees 17z - 03z with a high of 
110 expected. 


For the rest of southern Nevada, northwest Arizona and southeast 
California...For the 00Z Forecast Package...Daily wind pattern 
continuing at all sites with mainly southerly winds and gusts 20-25 
kts this evening. Expect wind speeds and gusts to diminish after 
sunset with KDAG being an exception. For KBIH, Guidance continues to 
show a push of westerly winds around 10kt over the next few hours, 
but confidence on if and when this could occur is lower. Better 
confidence in a shift to NW winds overnight and into the morning for 
KBIH. At KDAG, stronger westerly winds persist into the evening, 
with gusts to around 25-28KTs through midnight. Daily wind pattern 
expected again on Thursday with afternoon wind gusts of 20-25 kts. 
Lower confidence at KBIH tomorrow as hi-res guidance shows northerly 
flow persisting well into the day with a much a later switchover to 
the south. VFR conditions with no operationally significant cloud 
cover will continue.
