.KEY MESSAGES...

* Warmer than normal temperatures will continue through the end of
  the week, along with periods of breezy northerly winds down the
  Colorado River Valley this afternoon.

* Temperatures will gradually cool over the weekend and early next
  week, but conditions will remain dry although a few snow showers
  will be possible in the high Sierra.

.DISCUSSION...through next Wednesday.

A broad ridge of high pressure will remain over the region into this
weekend bringing us well above normal temperatures and clear skies.
Winds will be light over most of the area, but a tight surface
gradient over the lower Colorado River Valley continues to bring
gusty north winds to areas south of Davis Dam. Wind gusts near
Laughlin/Bullhead City have generally been around 40 mph and this is
expected to continue into this evening before winds diminish late.
Waves of 1-3 feet will be possible from Laughlin/Bullhead City to
Needles and any outdoor recreation and marine interests should
continue to use extra caution. Pressure gradients will weaken
Thursday and although a few wind gusts to around 20 mph will be
possible south of Davis Dam, overall winds speeds will be much lower.

Over the weekend and early next week, the ridge will flatten as a
shortwave embedded within the mean flow tracks across southern
California, Arizona, and northern Mexico. While no precipitation is
anticipated with this feature for most areas, an increase in high
cloud cover is expected, which will also help lower temperatures by
several degrees. A slight increase in moisture levels moving into
central California early next week may bring a few light snow
showers to the higher elevations of the Sierra in northern Inyo
County. At this point, snow amounts look to remain less than a
couple of inches.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds
under 8KT will follow typical diurnal directional patterns
through the forecast period, with some variability. VFR conditions
with clear skies will prevail.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...Across the region, winds
will remain under 10KT, following typical terrain-driven and diurnal
directional patterns. The exception will be along the Lower Colorado
River Valley where channeling of winds will result in elevated
sustained speeds of 12-18KT, with IFP seeing gusts to 20-30KT
through late this evening. VFR conditions otherwise prevail.
