Area Forecast Discussion
National Weather Service Las Vegas NV
243 PM PDT Mon Jul 27 2026

.KEY MESSAGES...

* Hotter than normal temperatures will continue through the end
  forecast period, with dangerous and potentially record breaking
  temperatures expected beginning Thursday.

* Isolated thunderstorm activity will be limited to Mohave County through
  Tuesday, with things drying out area-wide during the second half of the week.

.DISCUSSION...through Sunday.

Dry conditions prevail across the region this afternoon with just a
scattering of fair weather cumulus across the southern Great Basin and
northwest Arizona. We may see an isolated shower or thunderstorm across
northern Mohave County by this evening but in general drier conditions
have overspread the area with limited convective coverage expected the
remainder of the week going forward.

As the moisture profile decreases, our focus will shift to warming
temperatures late in the week as a large H500mb ridge builds westward
out of the Southern Plains. Ensemble agreement remains high for an
expansive 600dm high to build across the Southwest Friday and Saturday,
which may challenge all-time August records for some locations across the
Mojave Desert region. This will also result in widespread high to extreme
heat risk across much of the middle and lower elevations for several
days in a row. For more information regarding exactly which records are in
jeopardy later this week, see the CLIMATE section below.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...
South-southwest winds continue with gusts around 20 kts. Winds
reduce and gusts cut off after 04z. Temperatures look to stay above
100 degrees until slightly before 05z. Winds look to become lighter
into mid Tuesday morning and become more southeasterly. These winds
will become southwesterly again tuesday afternoon with gusts around
18 kts. These winds will reduce in the late evening on Tuesday,
becoming light through that night. Mostly clear skies are expected
through the TAF period.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Breezy winds are
affecting most the region with gusts peaking around 20 kts that will
last into the mid evening to early night before reducing. The
exception will be KDAG which has westerly gusts building through the
evening , peaking closer to 25 kts, and not reducing until the late
night/early Tuesday. Winds don`t look to increase again until the
late morning and early afternoon on Tuesday. Mostly clear skies are
expected through the TAF period.
