...COOLER WITH PRECIP CONTINUING TODAY MAINLY NEAR AND S OF I-80...
...DRY WITH WARMING TEMPERATURES THROUGH THE UPCOMING WEEKEND...

.METEOROLOGICAL CONDITIONS (TUE AM - MON AM)...

The upr low off the central CA coast moved inland yesterday and is 
currently spinning in the vicinity of Bakersfield at this time. 
Radar imagery shows scattered showers pinwheeling around this 
feature with the most pronounced echoes streaming onshore across 
coastal southern CA from Los Angeles to San Diego...while another 
line of showers moving toward the southwest is set up in a 
deformation zone generally just south of I-80 from northern NV to 
the northern San Joaquin Valley and eventually the SF Bay Area. So 
far...precip gauges since 05/12Z are reporting light amounts near or 
less than 0.10-inch.

Through the rest of today...look for the upr low to open up and 
shift off eastward across the Desert Southwest before phasing with a 
disturbance dropping southward over the Rocky Mountain states. 
Precip will slowly taper off overnight with the best totals 
stretching in a line from southern Elko county back southwest to the 
southern Sierra and coastal southern CA between Los Angeles and San 
Diego. Totals should range from 0.10- to 0.33-inch on average. 
Lighter amounts less than 0.10-inch are expected across the San 
Joaquin Valley and the SF Bay Area down to the Monterey Bay area. 
Freezing levels near and south of I-80 are currently running from 
7000-feet near the core of the system to almost 10000-feet and then 
recovering overnight as the coolest portion of the airmass moves off 
to the east...generally from 10000- to 12500-feet by Wednesday 
morning.

Building high pressure over the eastern Pacific toward the west 
coast will be the rule for the remainder of the forecast 
period...which goes through next weekend. Only a weak disturbance 
moving through the flow toward the Pacific Northwest on Friday will 
briefly slow down the anticipated warming. By Sunday...look for high 
temperatures to be anywhere from plus 10- to plus 20-degF over 
seasonal norms. Also...dry conditions will be the rule from 
Wednesday through the upcoming weekend. Beyond the forecast 
period...the warmth will continue into next week with the Climate 
Prediction Center showing a higher likelihood of above normal 
temperatures for the 8-14 Day Outlook...which covers May 12-18.
