.DISCUSSION...Today through Sunday.



Ridging continues through much of the work week, resulting in quiet 

weather, dry conditions, and generally light winds. The exception 

will be along the Colorado River Valley where gusty north winds will 

elevate as a result of a weak shortwave passage along the flow 

aloft. These gusty winds will occur on Tuesday and Wednesday 

afternoons with speeds between 25 and 35 mph, which will increase 

wave heights on Lake Mohave and Lake Havasu to 1 to 3 feet. 

Otherwise, temperatures will remain well-above normal through the 

forecast period, with afternoon highs 10 to 15 degrees above 

seasonal normals. 



Through the week, ensemble means continue to show a closed low off 

the coast of Baja California slowly moving northward along the 

shoreline. Late-week, this low will weaken into an open wave, phase 

with another incoming system from the eastern Pacific, and will push 

into the Desert Southwest. Details remain uncertain at this time, 

with ensemble ECMWF means favoring a swath of light rain across the 

Mojave Desert and ensemble GFS means favoring hit-or-miss sprinkles. 

This pattern change continues into the start of next week as 

troughing returns to the western CONUS.

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

through the forecast period will be around 5-7KT, generally

following typical daily directional patterns. Bands of mid-level 

and high clouds will gradually clear out through this afternoon, 

but with bases at or above 15kft, operational impacts are not 

expected. VFR conditions prevail.





For the rest of southern Nevada, northwest Arizona and southeast

California...For the 12Z Forecast Package...Across most of the

region, winds will remain around 5-10KT, following typical daily 

directional patterns with some variability. The exception will be 

along the Lower Colorado River Valley in the vicinity of KIFP, 

where elevated terrain-enhanced northerly winds with intermittent 

gusts to 15-20KT are expected late this morning into this 

afternoon, with winds becoming elevated again overnight. VFR 

conditions will prevail, with mid-level and high clouds between 

15-20kft gradually clearing from north to south through early 

evening.
