Synopsis
Near average temperatures, night and morning coastal low clouds
and mostly sunny skies inland will prevail through the 4th of
july. Brief periods of elevated fire weather conditions are
anticipated over and east of the mountains ridges each afternoon
and evening. Otherwise no potentially hazardous conditions are
expected.

Discussion For extreme southwestern california including orange...

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

at 130 pm, low amplitude ridging remained in place over the
southwest us. Skies were mostly clear, with low clouds limited to
the coastal waters. Winds remained breezy through the passes with
local gusts of 30-45 mph. As expected temperatures are noticeable
cooler than this time yesterday, with some locations over the
valleys running 10-15 degrees f cooler than this time yesterday.

The low stratus currently hovering off the coast should make a
push inland after sunset, bringing increasing low cloud cover to
the coast and western valleys through early Thursday morning.

Patchy dense fog is possible over the higher valley terrain.

Cooling will continue Tuesday, with 3-5 degrees f of cooling in
the 950-850 mb layer leading to an additional 3-6 degree f drop in
afternoon highs over the valleys.

Friday through the middle of next week, the forecast can be
described by one word "seasonal". Upper level ridging will
generally remain in place over or just off the west coast, as a
few weak troughs ride over the ridge. This will result in minor
day to day temperatures fluctuations, standard afternoon sea
breezes, and night and morning low clouds over the coast and
western valleys.

Toward the second half of next week, both the ECMWF and gfs
suggest a shift in the position of the upper level ridge axis
toward the four corners or western plains. Along with the
potential development of a weak mid level (850-500 mb) trough off
the west coast, this may allow for a push of monsoonal moisture
into the az ca nv region. Though uncertainty on the specifics of
the forecast remain high, moderate run-to-run consistency in the
global models lends itself to modest forecaster confidence in the
general synoptic pattern for this period.

Aviation
281900z... Coast valleys... Clear this afternoon except for a few low
clouds at the beach near the border. Extensive areas of low clouds
remain about 20 miles offshore. The low clouds will likely return to
the coastal TAF sites after 00z Thu with bases 1000-1500 ft msl and
tops near 2000 ft msl. Expect the clouds to spread into the western
valleys overnight, with vis 1-3sm where clouds and terrain
intersect. Confidence is moderate that kont will be impacted.

Mountains deserts... Clear skies with unrestricted vis will prevail
through Thursday. West winds locally gusting 20-25 kt will produce
llws and weak-mdt up downdrafts over and east of the mountains
through this afternoon. Winds will weaken by late evening.

Marine
No hazardous marine weather is expected through Sunday.

Fire weather
Breezy winds will continue this afternoon and evening over and
east of the mountain ridges, especially in riverside and san diego
counties, where westerly wind gusts of 25-45 mph are expected.

Relative humidity values will remain in the low teens and single
digits through this evening. As such, the fire risk remains
elevated. West of the mountain ridges, significant relative
humidity recovery will limit the fire risk. Minimum relative
humidity values in the single digits and teens and west winds in
the afternoons will keep the fire risk elevated over and east of
the mountain ridges through the 4th of july holiday.

Skywarn
Skywarn activation will not be through the middle of next week.

Sgx watches warnings advisories
Ca... None.

Pz... None.
