Synopsis
A developing low pressure system over the western states will
bring stronger onshore flow into Friday which will spread cooling
inland and bring periods of stronger and gusty southwest to west
winds in the mountains and deserts. The marine layer will deepen
with patchy drizzle and a chance of light showers for late tonight
into Friday morning. For the weekend into early next week, the
trough of low pressure will weaken and move east. There will be a
warming trend for inland areas, winds in the mountains and deserts
will weaken, and the marine layer will become a little less deep
with night and morning low clouds and fog not spreading as far
into the valleys. Minor day to day changes are then expected into
the middle of next week. Summer begins at 8:54 am Friday.

Discussion For extreme southwestern california including orange...

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

upper level low pressure centered over southern british columbia
and alberta early this morning will amplify across the western
states through Friday. This will strengthen the onshore flow
across southern california with periods of stronger and gusty
southwest to west winds in the mountains and deserts with the
strongest winds expected for this evening through late tonight.

Cooling will begin to spread inland today. The greatest cooling
is expected on Friday with high temperatures in the valleys and
mountains 15 to 25 degrees below average on the first day of
summer.

Early this morning, low clouds continue to spread into the valleys
and will cover most of the valleys by around sunrise. Additional
deepening of the marine layer will push low clouds onto the lower
coastal mountain slopes for late tonight into Friday morning.

Patchy drizzle is possible. A chance of light rain has been added
toward the coast as some of the higher resolution models move a
band of showers inland along the coast in the few hours centered
around sunrise.

The low clouds will once again extend inland across all of the
valleys and onto the lower coastal mountain slopes for Friday
night. There should be greater and faster clearing of the low
clouds on Saturday, especially in the inland empire as north flow
develops with gusty north winds along the coastal slopes of the
san bernardino county mountains for Saturday morning. Slow
warming will begin on Saturday with greater warming for Sunday and
Monday with high temperatures still near to slightly below
average for Sunday and Monday.

A low pressure system centered off the west coast on Monday will
move to a position along the west coast for the middle part of
next week. High pressure aloft will be to the southwest, from off
the baja coast into new mexico and texas. Southern california will
be in between with southwest flow aloft and minor day to day
changes. Night and morning coastal low clouds will continue to
spread into portions of the valleys with gusty southwest to west
winds in the mountains and deserts for each late afternoon through
late evening.

Aviation...

200900z... Coast valleys... Stratus with bases 1500-2000 ft and tops
to 2300 ft msl will continue to fill in west of the mountains this
morning. Local vis 3-5 sm in br hz in the valleys through 18z.

Clearing will occur inland 16-18z and near the coast 18-20z, though
some beaches will remain bkn-ovc through the afternoon. Stratus
moving back inland around 21 00z and spreading into the inland
valleys overnight. Bases will be near 1700-2500 ft msl with tops
lifting to 4500 ft msl and areas of drizzle overnight.

Mountains deserts... A few cumulus will develop over the mountain
crests this afternoon, otherwise mostly clear through this evening.

Coastal slopes will become obscured in clouds fog tonight into
Friday morning.

West winds with surface gusts of 30-40 kt occur over the mountain
crests, desert mountain slopes, and below passes this afternoon into
tonight. Areas of strong uddfs and rotors possible over and east of
the mountains.
