Area Forecast Discussion
National Weather Service Las Vegas NV
1236 AM PDT Fri Oct 31 2025

.KEY MESSAGES...

* Dry conditions and above-normal temperatures persist through the
  forecast period.

* Uncertainty exists mid-to-late next week regarding the strength
  of an incoming weather system capable of dropping temperatures,
  returning gusty winds, and brining precipitation to the Sierra.

&&

.DISCUSSION...Today through next Thursday.

A persistent ridge over the Desert Southwest will continue to
maintain dry conditions, light afternoon breezes, and above normal
temperatures through the weekend and first half of next week.
Temperatures will be 5 to 10 degrees above average for this time of
year. For Las Vegas, this means afternoon highs in the low 80s and
morning lows in the upper 50s to low 60s.

Uncertainty creeps in mid-to-late week as a trough moves east from
the Pacific Ocean into the Great Basin. The depth of this trough
will determine the strength of forecast wind speeds and the
magnitude of temperature drop that occurs on Wednesday and Thursday.
Moisture associated with the trough also brings a 30 percent
probability of precipitation to the eastern Sierra. Overall details
should become more apparent with upcoming forecasts.
