Synopsis
Into next week, high pressure aloft will be centered near the west
coast with a broad trough of low pressure covering much of the
rest of the lower 48 states. Lower level flow will be mostly
offshore with gusty northeast winds along and near the coastal
mountain slopes and below passes and canyons at times. These
winds could be stronger and more widespread for late Friday night
into Saturday and again around Tuesday. High temperatures will be
mostly above average.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

high pressure aloft will remain centered near or just off the west
coast through the middle of next week with a broad trough of low
pressure covering much of the rest of the lower 48 states. The
lower level flow will be mostly offshore across southwest
california into next week, but may turn briefly onshore near the
coast in advance of shortwaves move southward through the western
states. These shortwaves will modulate the timing and the strength
and coverage of the offshore winds.

Weaker and more localized gusty northeast winds will continue near
and along the coastal slopes of the mountains and below passes and
canyons at times into Thursday. A weak shortwave moving southward
through the area Thursday night and Friday will continue the gusty
northeast winds on Friday similar to Thursday.

Periods of stronger and more widespread winds are possible along
and behind shortwaves for late Friday night and Saturday and again
Tuesday. The global models are closer on the timing and amplitude
of these shortwaves for Friday night and again on Tuesday. Given
the pattern, it would not be surprising to see some timing and
amplitude changes between now and when those shortwaves followed
by stronger winds occur.

A wind advisory continues for the windier areas until noon today.

There have been a few locations with gusts greater than 40 mph in
the past few hours, but most locations have had gusts less than
40 mph.

Based on current guidance, the events for late Friday night into
Saturday and again on Tuesday look more like advisory strength
events with more widespread coverage, though there is the
potential for either or both to end up stronger.

Some stratus could return near the coast for Monday night into
early Tuesday ahead of the shortwave Tuesday, but with low
confidence in that possibility.

High temperatures will be mostly above average into next week with
the warmer temperatures moving closer to the coast during the
periods of stronger and more widespread offshore winds, around
Saturday and again next Tuesday with some cooling for inland
areas on those days with stronger lower level cold advection.

Aviation
231000z... Clear skies today and tonight. Areas of winds in foothills
and into portions of valleys and coast will continue through about

over and SW of mountains this morning.

Marine
No hazardous marine weather is forecast through Sunday.

Skywarn
Skywarn activation is not requested. However weather spotters are
