AREA FORECAST DISCUSSION
National Weather Service San Diego CA
331 AM PDT WED JUN 1 2016
...First Major Heat Wave of the Season Inland Late Week...
...High Risk of Rip Currents; Rough Surf at the Beaches...
.SYNOPSIS...
High temperatures will rise throughout the week as high pressure
builds aloft. Highs for inland areas are forecast to rise 10 to
20 deg F above normal Friday and Saturday with the heat becoming
intense over the lower deserts, but very hot over the upper
deserts and the Inland Empire as well. A shallow marine layer will
maintain seasonal weather along the coast throughout the week. Low
pressure moving over the area early next week will create seasonal
weather across the region.
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
Short term concern is the southerly swell, resulting in strong
rip currents and rough surf along the beaches (see beach section
below)...then we look to building heat concerns late week.
Water vapor imagery shows a ridge of high pressure building over
California. Benign weather will prevail underneath this ridge. The
marine layer stratus will continue near the coast/inland valleys,
but is forecast to become shallower with time through late week.
The result will be more afternoon sunshine, especially away from
the immediate coast.
The big weather story is the heat. This ridge will strengthen
such that by Fri- Sat, we expect the heat to become intense over
the Coachella Valley with 110F+ forecast there. Temps will become
hot over the Upper Deserts and Inland Empire as well...with many
locales eclipsing the triple digits. The Excessive Heat Watch
continues in effect for these areas Fri-Sat.
Coastal locales will remain seasonably cool due to the presence of
the marine layer. However, as the marine layer becomes more and
more shallow with time, it looks as though it will warm
considerably just inland from the coast, and especially across
areas east of I-15 in San Diego County and east of I-5 in Orange
County. The trend in the model guidance is warmer across these
areas...so followed suit.
Upper-level heights will quickly lower Sunday as an upper-level
low pushes the ridge to the east and moves over SW CA. This will
strengthen onshore flow, deepen the marine layer, and help high
temperatures return to seasonal normals around the region. No
precipitation is expected over the next week at this time.

010900Z...Coast/Valleys...Low clouds will continue a gradual march
inland with bases around 1000-1200 feet msl and tops to 2600 feet.
Vis 3-5sm in fog in inland valleys and higher coastal mesas. Clouds
will clear toward the coast through 18Z, but cigs will continue over
coastal areas through the afternoon. Low clouds will push inland
after 02Z this evening, but with less inland extent tonight.
Mountains/Deserts...Mostly clear skies today and tonight, except for
scattered cumulus over the mountains this afternoon.

.BEACHES...
A 14 to 15 second period south swell (from 190-200 degrees) will
bring above average surf and strong rip currents through Thursday.
The highest surf will be on south facing beaches of Orange County
and northern San Diego County where surf of 3-6 FT is forecast
with sets to 8 FT. The south swell will subside Friday and
Saturday.
