832 PM PDT sun Mar 29 2015 

Synopsis...high pressure aloft over the west will weaken through 
Thursday resulting in a slow cooling trend. Areas of night and 
morning low clouds and fog will continue along the coast...and may 
spread farther inland by Thursday as gusty onshore flow develops 
over the mountains and deserts. Fair and warmer again late in the 
week with weak offshore flow...then much cooler beginning late in 
the weekend as a cold trough drops south along the West Coast... 
accompanied by a deeper marine layer and gusty westerly winds across 
the mountains and deserts. 


Discussion...for extreme southwestern California including Orange... 
San Diego...western Riverside and southwestern San Bernardino 

As was the case yesterday evening...high clouds have thickened 
across the region obscuring the lower clouds. However...where 
visible...lower clouds were evident over the California bight and farther 
offshore. The 00z Miramar sounding had a weak inversion based near 
1500 feet. The surface pressure gradients were almost neutral from 
Nevada...but had increased onshore to 4-6 mbs to the lower deserts. 
Winds were generally light. 

Based on the height of the moist layer...and decreased dewpoint is likely some patchy radiational fog will develop 
overnight as the higher clouds break...but difficult to pinpoint 
exact locations. 

Broad ridging aloft will continue over the west through Monday...then 
flatten as a series of short waves slide east off the Pacific. This 
will suppress heights/thickness over California through Thursday...and continue 
onshore flow and a marine layer west of the mts. Winds will become 
gusty over the mts/deserts as the troughs pass by to the north...and 
daytime temperatures will gradually lower inland. 

For Friday...ridging will follow...swinging surface winds back offshore 
across socal as high pressure builds into the Great Basin. Depending 
on the strength of the offshore push...daytime temperatures could 
climb back up to near 80 along the coast before winds turn back 
onshore Sat afternoon. 

More significant changes may be in the offing late next weekend 
through the following week as a colder trough settles over the West 
Coast. Several of the ec/GFS deterministic runs have suggested a 
flip-flop of the persistent West Coast ridge/East Coast trough 
pattern for the week of April 5. The latest available runs also have 
precipitation over socal centered around April 8. So...perhaps we will have 
a chance of more precipitation before the season shuts down 


Aviation... 300300z...coastal areas...patches of low clouds are 
beginning to return to the immediate coast at this time. They will 
likely impact the coastal taf sites after 05z with broken-overcast ceilings 
between 900 and 1200 feet mean sea level and tops to 1500 feet. Expect reduced visible 
in areas where clouds and terrain intersect...mainly along the 
coastal mesas. Low clouds and fog will likely clear by 16z Monday. 

Valleys/mountains/deserts...sct-few clouds at or above 15000 feet with 
unrestricted visible through Monday. 



800 hazardous marine weather is expected through Tuesday. 



800 PM...slightly elevated surf will continue through the first half 
of this week though the rip current threat will gradually diminish 
as the swell period decreases. 


Skywarn... Skywarn activation is not requested. However weather 
spotters are encouraged to report significant weather conditions.
