  Colorado River Valley this afternoon.

  week, but conditions will remain dry.

.DISCUSSION...through next Tuesday.

Little change in the overall synoptic pattern is forecast into the 
weekend as a broad ridge of high pressure remains firmly in place 
over the western US. This will maintain well above normal 
temperatures through the end of the week, with a few locations 
nearing or exceeding daily records through Friday. See the CLIMATE 
section below for more information. A weak trough centered over 
northern Mexico will allow for one more day of enhanced northerly 
winds across portions of the lower Colorado River Valley, primarily 
south of Davis Dam. While winds will be a bit lighter today compared 
to yesterday, a few gusts to 30 mph and waves of 1 to 2 feet will be 
possible from Laughlin/Bullhead City to Needles. Given the isolated 
nature of these conditions, no headlines are planned. However, 
outdoor recreation and marine interests should continue to use extra 
caution, particularly near and south of Davis Dam. 

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, 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.

.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.
