Area forecast discussion
National Weather Service San Diego California
912 PM PDT Thursday Aug 28 2014
high surf will continue through Friday along favored southwestern
California beaches. High pressure will bring above normal
temperatures through the end of the week. Low pressure developing
along the West Coast next week will create dry southwest flow...a
deeper marine layer with night and morning low clouds and fog
along the coast...and below normal temperatures across the region.
Discussion...for extreme southwestern California including Orange...
San Diego...western Riverside and southwestern San Bernardino
It was a very hot day today across much of southwest California
with temperatures 5 to 10 degrees above normal in most areas. We
are seeing signs that the marine influence is being noted near
the coast with the 00z Miramar sounding showing a bit of a
stronger marine inversion compared to 24 hours ago. Coastal observation
sites are running a few degrees cooler at this time compared to
24 hours ago. Cooler weather will be noted along the coast and in
the coastal valleys for Friday. Meanwhile will little airmass
change inland locations will be just as hot as today if not a
degree or so hotter. With that in mind have updated the temperatures for
tomorrow for inland areas to bump them up a notch to be more in
line with current trends and observation. No other changes were made at
this time to the ongoing forecast.
290330z...mostly clear through 08z. Moderate confidence in areas of
scattered-bkn008-012 forming near the coast between 10-15z. Low confidence
that these areas of low clouds will reach ksan/kcrq/ksna Friday.

830 PM...swell height and period from Tropical Storm Marie continue
to decrease. At 8 PM the San Clemente basin buoy reported 7 feet at
11 seconds...down from 9 feet at 12 seconds from Wednesday evening.
The southerly swell will continue to decrease Friday. No marine
weather hazards are expected through Monday.
830 PM...Tropical Storm Marie is weakening and will become
subtropical overnight. Its south swell will continue to decrease
Friday...but still be high enough to generate high surf at the
Orange County beaches. Surf tonight will range from 6 to 8 feet with
sets to 10 feet...then lower Friday to 4 to 7 feet with sets to 8
feet. A high surf advisory remains in effect for the Orange County
beaches through 8 PM Friday.
San Diego County beaches will see 4 to 6 foot surf tonight with sets
to 7 feet on the beaches north of Oceanside. The surf will decrease
to 3 to 5 feet on Friday...but strong rip and longshore currents
will continue. A beach hazards statement for the San Diego County
beaches is in effect through 8 PM Friday.
