.DISCUSSION...Today through Friday.



A deep trough associated with a closed low over the Gulf of Alaska 

will push through the western CONUS this weekend, bringing along with

a 115-125 kt 250mb jet streak. The resulting cross-barrier flow 

will cause gusty west winds to the Sierra Crest today and Sunday, 

with downslope potential into the Owens Valley. Chances of 40 mph 

wind gusts crossing Highway 395 near Bishop are around 20 percent 

this afternoon and 20-30 percent on Sunday. The other area of 

concern is the western Mojave Desert including western San 

Bernardino County, where there is a 20 percent chance of gusty 

west winds in excess of 40 mph tonight and 20-30 percent Sunday 

(greater chances in the higher terrain). Elsewhere, expect gusty 

south- southwest winds on this weekend between 20 and 30 mph.



Otherwise, expect near-normal temperatures and no chance of 

precipitation this weekend and through next week. With the passage 

of the aforementioned trough, a dry northwesterly flow will set up 

aloft for the work week. Expect occasional shortwave passages along 

this flow, which will increase afternoon breeziness, particularly 

along the Colorado River Valley, so boaters are urged to check the 

forecast before heading out on area lakes.
