Area Forecast Discussion
National Weather Service Las Vegas NV
201 AM PST Sat Dec 13 2025

.KEY MESSAGES...

* Warm and mild weather will continue across southeastern
  California, southern Nevada, and northwestern Arizona into next
  week.

* There is a 10 to 20% chance for precipitation in the crest of the
  Eastern Sierra during the second half of the week.

.DISCUSSION...through next weekend.

Expansive ridge will remain the dominant weather feature through
the week, with dry conditions and mild temperatures continuing.
Light winds and the low sun angle will favor valley surface
inversions so some of the lower sheltered valleys may struggle to
warm a bit, particularly near Death Valley where the lower reaches
of Furnace Creek have been coming up short of the forecast the
past few days. Otherwise - temperatures will remain 8 to 12
degrees above seasonal normals.

The upper level pattern will begin to deamplify later in the week
and trend more zonal, and while the affects of this will be
subtle for most of the region - the storm track will shift further
south into northern California and will allow for some slight
chances for light precipitation along the eastern Sierra Crest
with passing weather disturbances. Otherwise, generally dry
weather remains favored - with hints at a more substancial
pattern shift as we approach the Christmas holiday.
