.DISCUSSION...through next week.



Another warm afternoon is underway across the region with mostly

clear skies. The current temperatures as of the 1 pm hour are near

or exceeding 80 degrees across the lower Mojave Desert valleys,

and 60s and 70s across the southern Great Basin and Owens Valley.

A handful of dally records are again probable today. Enhanced

surface mixing via elevated southwesterly surface winds will help

boost temps to their peak on Sunday before a modest cooldown

arrives for Monday and Tuesday. Heat risk through the weekend will

remain in the Minor category (level 1 of 4), primarily impacting 

those without access to adequate cooling or hydration as well as 

those visiting from cooler climates.



Early next week, a weak low pressure system will creep across the

Great Basin, resulting in a reduction in heights and subtle cooling

of regional temperatures. In addition, gusty southwesterly winds 

will overspread much of the area, especially the Western Mojave 

Desert near Barstow with wind gusts of 40-50 mph expected. Some 

minor precipitation chances are also advertised along the southern

Great Basin, closer to the cooler air aloft associated with the 

trough, though any precipitation amounts are expected to be light.



Heights will rebound midweek with some brief shortwave ridging

building in, however, a secondary, stronger shortwave is expected

to drop south into the region Thursday into Friday. This will 

result in an additional uptick in gusty winds and reinforcing shot

of cooler air, sending high temperatures downward closer to early

March normals.

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

Package...Light winds are expected through Sunday morning. East 

winds will set up briefly Sunday afternoon before southwest winds 

push through the terminals, likely around 20Z. Gusts of 20-25KT can 

be expected with these southwest winds. After sunset, wind gusts 

will end but elevated wind speeds over 10KT will continue into the 

evening and Sunday overnight. SCT to BKN high clouds with bases 

around 15kft will continue to stream through the area. 



For the rest of southern Nevada, northwest Arizona and southeast 

California...For the 06Z Forecast Package...Light winds are expected 

overnight in most locations. Winds will increase out of the west to 

southwest across the region Sunday late morning and afternoon. West 

winds should develop at KBIH after 21Z with a 30% chance for gusts 

over 30KT into the evening before diminishing after 03Z. Elsewhere, 

gusts of 20-30KT gusts will develop Sunday afternoon except in the 

Colorado River Valley where south winds at 8-10KT will persist 

through much of the day. Lighter winds will return after sunset. VFR 

conditions with SCT to BKN high clouds will continue to stream 

through the area.
