Area Forecast Discussion
National Weather Service Las Vegas NV
310 AM PST Thu Dec 11 2025

.KEY MESSAGES...

* Warmer than normal temperatures will continue through tomorrow,
  and another period of breezy northerly winds is expected down the
  Colorado River Valley this afternoon.

* Temperatures will gradually cool over the weekend and early next
  week, but conditions will remain dry across most areas.

.DISCUSSION...through next Thursday.

High pressure will remain in place across the region into the
weekend, maintaining well above normal temperatures and clear skies.
See the climate section below for additional details on potential
record temperatures today and Friday.  Winds will be light over most
of the area, except in the lower Colorado River Valley where a
tightened pressure gradient will maintain breezy north winds,
generally near and south of Davis Dam. Waves of 1 to 2 feet will
still be possible today from Laughlin/Bullhead City to Needles, and
any outdoor recreation and marine interests should continue to
exercise caution. The pressure gradient will weaken by the weekend,
allowing winds to decrease.

Over the weekend and early next week, the ridge will flatten as a
series of shortwaves embedded within the mean flow track across
southern California and northern Mexico. No precipitation is
anticipated with this system, but an increase in high cloud cover is
expected, which will help lower temperatures by several degrees. A
slight increase in moisture moving into central California next week
may bring a few light snow showers to the higher elevations of the
Sierra in far northern Inyo County. However, at this point, snow
amounts are expected to be light (a few inches), and no significant
impacts are anticipated.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Light

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Clear skies through the
TAF period. Light winds with typical directional patterns are
expected in most location. The exception will be the Colorado River
