.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.
