.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

Skies remain clear this morning with light winds across the
region. Pressure gradients will be nearly neutral to the local
deserts through Sunday morning, allowing for a weak sea breeze to
develop this afternoon. With the return of this weak onshore
flow and a forecasted weak coastal eddy tonight, we could see a
development of dense fog over the coastal waters and locally into
the coastal areas tonight into Sunday morning. Weak offshore flow
kicks back in on Sunday morning, helping to clear out any fog.
Patchy dense fog may briefly return again Sunday evening before
slightly stronger offshore flow develops Sunday night. Aside from
that, there will be gradual warming through the weekend as an
upper level ridge of high pressure begins to build in from the
west. High temperatures today will be around 3-7 degrees above
normal, increasing to around 5-10 degrees above normal for Sunday.

Next week can be summed up with warm and dry. The upper high
slowly shifts east through the week, directly overhead by Friday.
At the surface, mostly weak Santa Ana winds will prevail, becoming
locally moderate on Tuesday morning as surface gradients peak.
With no upper level support, winds will remain confined to the
usual passes, canyons, and coastal slopes and follow a diurnal
pattern, strongest in the mornings and then weakening during the
afternoon. On Tuesday morning, northeast to east gusts in the
wind prone locations will generally peak around 30-45 mph. Monday
and Wednesday through Friday will see peak gusts closer to 20-35
mph. Only minor daily fluctuations in temperatures is expected,
with highs generally 10-15 degrees above normal each day Monday
through Saturday. Dry air and weak winds overnight will allow for
decent cooling, so HeatRisk remains low. For the valleys and
deserts it will very much be a winter in the morning, summer
(highs in the low 80s) for a few hours in the early afternoon,
and fall in the evening sort of pattern.

The forecast becomes a little more uncertain towards next weekend
with the upper high potentially beginning to weaken or break down,
influencing how much cooling we`ll see and whether or not onshore
flow will return. Still no signs of precipitation around here
until the second half of the month.

.AVIATION...
061000Z....Predominately clear skies and VFR conditions through the
TAF period. Chances for some patchy fog for TAF sites along the
immediate coast after 03Z Sunday. The San Diego County coast line
will see chances around 10-20% through 12Z Sunday and Orange County
will see slightly higher chances around 30-40% through 19Z.
Confidence is not high enough in VIS restrictions below VFR to
include fog in the TAFs at coastal sites at this time.

No hazardous marine conditions are expected through Thursday.
