National Weather Service San Diego California
330 am PDT Thursday Aug 28 2014
large swells from former Hurricane Marie will continue to bring
high surf along with dangerous rip currents to Orange County and
northern San Diego County today. High pressure centered off the
Southern California coast will bring warmest temperatures for
coastal areas today with slow warming for inland areas into
Saturday. Slow cooling near the coast Friday will spread slowly
inland for the weekend as a low pressure system moves inland to the
north increasing onshore flow for Southern California. Areas of
night and morning coastal low clouds and patchy fog will return for
the weekend. For next week dry southwest flow aloft will continue
with near seasonal high temperatures.
Discussion...for extreme southwestern California including Orange...
San Diego...western Riverside and southwestern San Bernardino
The strength of the high pressure area centered off the Southern
California coast will peak today...then slowly weaken Friday into
the weekend as a trough of low pressure moves inland to the north
strengthening the onshore flow across Southern California.
High temperatures near the coast will peak today a few degrees
higher than Wednesday...then begin to cool for Friday through the
weekend as the onshore flow strengthens and the marine layer slowly
deepens. Areas farther inland will continue to slowly warm into
Friday or Saturday...then begin to slowly cool.
For coastal areas...little or no stratus is expected this morning...
then maybe very patchy coverage near the San Diego County coast late
tonight into Friday morning. The workstation WRF does show the
development of a coastal eddy Friday night with a return of stratus
northward along the coastal strip late Friday night into Saturday
morning with deepening into the western valleys for late Saturday
night into Sunday morning.
For next week...a trough of low pressure to the northwest and high
pressure to the east will bring dry southwest flow aloft with near
seasonal high temperatures.
