Area Forecast Discussion
National Weather Service Las Vegas NV
143 AM PDT Fri Jul 31 2026

.KEY MESSAGES...

* Hazardous heat will continue into early next week.

* Monsoon moisture returns late next week.

&&

.DISCUSSION...through Thursday.

Temperatures will continue increase over the next few days as
ridging continues to build over the area. Over the weekend,
temperatures will peak around 5 to 10 degrees above normal as the
ridge moves directly overhead. Temperature over the weekend will be
the hottest of the year for much of the region ,with daily and
monthly records in jeopardy for a number of our climate sites in the
coming days. These temperature will yield widespread Major-to-
Extreme HeatRisk (Levels 3 and 4 of 4, respectively) over the
weekend and into early next week. Daytime temperatures will be
brutal, and overnight low temperatures will offer little-to-no
relief in places like Las Vegas, Death Valley, and the Colorado
River Valley where temperatures will bottom out in the 85 to 100
degree range overnight. Hotter than normal temperatures will
continue into early next week.

A shortwave will move along the US-Canadian border early next week,
knocking 500 mb heights down slightly and stretching the ridge
zonally across the southern US. As the ridge attempts to reestablish
itself over the Four Corners region, we will see upper-level flow
become more southeasterly. These southeasterly winds will help
transport moisture into the area during the second half of next
week. Currently, even with this increase in moisture, the best
chances for showers and thunderstorms remain limited to Mohave
County on Wednesday and Thursday.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...
Southwest winds at or below 8 kts will persist through the overnight
hours then become light and variable after sunrise. Friday`s set up
favors light easterly to southeasterly winds developing after 20z.
Higher confidence in winds remaining under 10 kts but isolated gusts
to 15 kts are possible during the later afternoon and evening.
Eventually winds should switch to the SW, but confidence is lower on
exact timing...thinking by 03z winds will flip to SW under 8 kts
tomorrow evening. Mostly clear skies persist. Temperatures will
exceed 100 degrees again on Friday 17Z-05Z.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Daily wind patterns
expected at all sites with fairly light winds overnight then
increasing southerly winds 8-10 kts during the late afternoon and
evening hours. The exception will be the western Mojave Desert and
KDAG where west winds 10-15 kts remain elevated through the night,
then diminish late morning. Winds on Friday should be lighter than
today and follow typical daytime wind direction. Mostly clear skies
with VFR conditions will continue through the period.
