.KEY MESSAGES...



* Outside of breezy northerly winds in the Colorado River Valley,

  dry and mild conditions with warmer than normal temperatures

  will continue into next week.



&&



.DISCUSSION...through next Thursday.



Breezy north winds will linger down the Colorado River Valley for a 

few more days with gusts peaking in the 20 to 30 mph range. 

Otherwise, weather across the region will remain dry and mild with 

warmer than normal temperatures continuing into next week as ridging 

persists over the region. A series of shortwave troughs embedded 

within the upper-level flow will move through the region beginning 

tomorrow, bringing periods of increased cloud cover to the region. 

These shortwaves will also cause temperatures to decrease a few 

degrees as we see 500 mb heights decrease slightly and the upper-

level flow becomes more zonal. However, even with this slight 

decrease, temperatures will remain well above normal through next 

week.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds 

generally follow typical daily directional patterns with speeds of 

less than 8 knots throughout the forecast period. Variable winds 

develop this afternoon, but may favor an easterly to northeasterly 

direction at times. FEW to SCT high clouds at or above 25kft move in 

overnight and Saturday morning. 



For the rest of southern Nevada, northwest Arizona and southeast

California...For the 18Z Forecast Package...Winds are light and 

follow typical directional patterns for most locations throughout

afternoon in the Colorado River Valley, including peak gusts between 

25 and 30 knots near KIFP. These winds should weaken overnight. FEW 

to SCT high clouds at or above 25kft move in overnight and Saturday
