.KEY MESSAGES...



* Expect increasing southwest winds and cooling temperatures this

  weekend and into next week.



&&



.DISCUSSION...through Friday.



A persistent trough will be the main driver of weather through the 

weekend and next week. First, temperatures will fall back to near 

normal values by Sunday, which means highs in the upper 90s to low 

100s across much of the Mojave Desert. HeatRisk decreases from 

Moderate(Level 2 of 4) to Minor (Level 1 of 4) for most locations as 

a result. Highs should remain within a few degrees of normal 

throughout the week. The position of the trough will allow for an 

increase in southerly to southwesterly winds across much of the 

area. The strongest gusts should generally remain in the 30 to 40 

mph range today, which will create rough waters and waves between 2 

and 4 feet on Lake Mead and Lake Mohave. Gusty winds combined with 

dry conditions also raise elevated to critical fire weather 

concerns - see the FIRE WEATHER discussion below for more 

details. Winds may weaken a bit on Sunday, but are expected to 

strengthen again on Monday and Tuesday as the trough becomes 

reestablished. Additional periods of breezy winds are possible 

later in the week depending on the strength and position of the 

trough, but confidence in this setup is lower at this time.

.AVIATION...For Harry Reid...For the 06Z Forecast 

Package...South winds at around 10KT are expected through the night. 

Gusty southwest winds will return Saturday late morning and 

afternoon. Gusts 20-25KT are expected in the late morning before 

increasing to around 30KT in the afternoon. Winds will continue to 

gust into Saturday night, but gusts should drop back closer to 20-

25KT after sunset. VFR conditions with clear skies become SCT-BKN at 

or above 20kft Saturday will persist through the period. 

Temperatures will climb over 100 degrees again Saturday 20Z through 

02Z. 



For the rest of southern Nevada, northwest Arizona and southeast 

California...For the 06Z Forecast Package...Southwest winds at 8-

10KT are expected for many locations overnight. The exception is 

around KDAG where west winds around 15KT will continue through much 

of the night. On Saturday, stronger southwest winds are expected 

across the area as 25-35KT gusts develop in the late morning and 

afternoon. Gusty winds will continue into the evening instead of 

diminishing like hey usually do. VFR conditions will persist through 

the period.



&&



.FIRE WEATHER...A combination of widespread southwesterly winds of 

15 to 25 mph gusting between 30 and 40 mph, minimum RH values 

between 5 and 15 percent, and dry fuels bring critical fire weather 

conditions to much of the area today. Red Flag Warnings cover all of 

southern Nevada and northwestern Arizona except for Nevada Zone 460. 

This warning continues into Sunday for northwestern Arizona, where 

gusty winds will persist as the trough moves east. Another round of 

gusty winds and dry conditions is expected on Monday and Tuesday as 

the trough strengthens again, and a Fire Weather Watch has been 

issued for all of northwestern Arizona and most of southern Nevada 

for this time as well.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report

any significant weather or impacts according to standard operating
