Synopsis...isolated showers will continue over the area through 
the remainder of the evening. Dry weather is forecast to return by 
Sunday. High pressure will build over the state from Monday 
through midweek...resulting in a warming trend. The next Pacific 
storm is forecast to bring renewed rain chances to the region by 
Thursday night or Friday.

Discussion...as of 8:50 PM PDT Saturday...isolated light showers 
continue across the area this evening...but radar shows that 
shower activity continues to gradually taper off. This is 
consistent with latest model data which mostly indicate an end to 
all precipitation by late this evening. A forecast update earlier this 
evening included a reduction in late night probability of precipitation to no more than 
slight chance. 


Dry weather is expected to return to all areas by Sunday morning. 
Skies are forecast to become mostly sunny. Cool northwest breezes 
will keep inland temperatures a bit below normal. 


A low amplitude upper ridge is forecast to build over California 
during the first half of the work week...resulting in continued 
dry weather along with a gradual warming trend through midweek. 


The medium range models have come into much better agreement 
regarding the system due in near the end of next week. It now 
looks like rain could move into our area as soon as Thursday 
night...with rainfall most likely on Friday and Friday night 
(halloween). The models also indicate this system could be quite a 
bit wetter than today's system. Of course...this is still nearly 
a week out and much can change.

Aviation...as of 10:20 PM PDT Saturday...there's a fair amount of 
humidity around the region per recent rainfall moistening the low 
levels of the atmosphere. Partial clearing tonight will allow for 
raditional cooling and possibly a few patches of fog very late at 
night. Ksts will likely see IFR ceilings and visibilities late 
tonight. 


Vicinity of ksfo...VFR. Light winds tonight. 


Ksfo bridge approach...similar to ksfo. 


Monterey Bay area terminals...VFR. Light winds tonight. 


&& 


Marine...as of 02:50 PM PDT Saturday...west to northwest winds 
will continue to diminish through tonight as a strong surface low 
pressure pulls away from the region. In addition...a large 
westerly swell moving through the waters will slowly subside 
overnight. Wind speeds will then increase again Sunday afternoon 
and evening over the coastal waters as high pressure builds off 
the California coast.
