...ONE MORE DAY OF COOLER AND UNSETTLED...

...DRY AND WARM FOR THE UPCOMING WORK WEEK...



.METEOROLOGICAL CONDITIONS (SUN AM - SAT AM)...



Another 24 hours of cooler and unsettled conditions on tap as a 

vertically stacked system currently moving inland along the central 

CA coast slowly shifts off toward the east across the southern 

Sierra and then eventually extreme southern NV before exiting to the 

east over the 4-Corners region on Monday. Two areas of precip this 

morning with the first focusing on areas along the central coast 

down to Point Conception and inland over the southern San Joaquin 

Valley and adjacent Sierra locations...in close vicinity of the 

primary circulation moving inland. The next is on the northern edge 

of the cyclonic flow where an area of convergent flow is generating 

precip dropping southwest across northern CA almost down to the I-80 

corridor...while showers over northern NV are rotating from 

southeast to northwest. Through this afternoon...precip near the 

CA/OR border will focus mainly over the upper Klamath River basin 

and the northeast CA Plateau...while down south the area of precip 

closer to the primary circulation will move across the extreme 

southern Sierra and transverse mountains between eastern Santa 

Barbara county across Los Angeles county. Then overnight into early 

Monday...precip will be on the decrease as the upr low moves east 

and drier north to northwest flow begins to set up across the region 

as an upr ridge builds over the eastern Pacific. 



Freezing levels this morning are lowest across northern CA from 3500-

to 4500-feet and then 4000- to 5500-feet for central CA. Inland and 

south where the coldest air has yet to filter overhead...these still 

are elevation with 7000- to 9000-feet across eastern NV down toward 

the southeast CA deserts. As the upr low moves inland...cooler air 

will make it over NV into early Monday with freezing levels down to 

5500- to 7000-feet...slightly higher for the southeast CA deserts. 

Warmer air will already be making its way along northern/central CA 

coastal areas...with freezing levels bouncing back closer to 8500- 

to 9500-feet. Through the week...these will rebound across the 

entire region...ranging from 8000-feet well north and east to just 

over 14000-feet along the CA/MX border.



Much of the upcoming work week will be dry with warmer temperatures 

on tap as the upr ridge aligns itself along or just off the west 

coast with flow generally west to northwest. Models are hinting at 

the possibility of a very weak disturbance moving through the flow 

across central/southern CA and southern NV on Friday...but right 

now...it appears as if at best there will be a few build ups over 

the southern Sierra on Friday afternoon with a rogue shower or two 

developing near the crest.
