.SYNOPSIS...
Slightly cooler conditions expected into Monday. Patchy dense fog is
possible over the coastal waters and along the immediate coast
tonight into Monday, with the potential for patchy dense fog to
develop Monday night into Tuesday. Warmer conditions return for the
middle to end of next week, with periods of Santa Ana winds. Cooler
conditions and onshore flow return for the end of the week.

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

Weak onshore flow returns for today and Monday as a weak trough
moves across the West Coast. This will allow the marine layer to
rebuild after a period of prevailing offshore flow. Patchy dense fog
is expected to develop tonight over the coastal waters and along the
immediate coast. Areas of visibility of 1 mile or less may impact
travel at times. Patchy dense fog may redevelop for Monday night
into Tuesday for similar areas and with similar impacts.

Highs today are expected to be a few degrees cooler than yesterday
along the coast and western valleys, with cooling spreading further
inland for Monday. Even with widespread cooler conditions on Monday,
highs will remain 5 to 10 degrees above average, locally up to 15
degrees above average in the mountains. By Tuesday, an upper level
high pressure will settle over the West Coast, kicking off another
period of warming. Wednesday is currently forecast to be the warmest
day of the week. West of the mountains widespread highs in the upper
70s to upper 80s, locally low 90s are expected. The mountains and
High Desert will see highs in the upper 60s to low 70s, with highs
in the low desert in the 80s. The majority of global ensembles show
the upper level high pressure shifting east on Thursday, which will
allow for a few degrees of cooling across the area but maintain
above average temperatures.

With the upper level ridge in place over the Western United States,
a surface high is expected to form over the Great Basin for the
middle to end of the week. This will bring another period of Santa
Ana winds. The CW3E West-WRF ensemble guidance maintains a 60 to 80
percent chance of a weak to moderate wind event with a 30 percent
chance of a moderate wind event for Wednesday and Thursday. Current
guidance indicates locations more prone to easterly/northeasterly
winds will be more impacted than areas more prone to northerly
winds.

Uncertainty grows for Friday onward as ensemble solutions begin to
diverge on the evolution of the upper level pattern, particularly
with the progression of an upper low moving into the West Coast. A
cooling trend for Friday and Saturday looks likely, but how much
cooling we`ll see will depend on how the low tracks. A few members
of each of the global ensembles are producing light precipitation
with this low over the weekend, but not enough to introduce a slight
chance into the forecast. The alternative to any precipitation would
be another round of offshore flow and warming conditions by Sunday.
