What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

125 pm pdt Wed may 23 2018

Synopsis
A deep trough moving into the region will bring more may gray and
cooler than average weather through Sunday. There may be areas of
light rain or drizzle in the deep marine at times the next few
mornings. Gusty west winds will continue in the mountains and
deserts, strongest on Friday and Saturday. The trough weakens Sunday
for better clearing, warmer days, and a shallow marine Monday and
Tuesday. Another trough will bring back cooler weather and a deep
marine layer next Wednesday and Thursday.

Discussion For extreme southwestern california including orange...

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

the inversion was stronger this morning (14c at 850 mb) compared to
Tuesday morning (10c at 850 mb) and that resulted in slower clearing
today. The inversion will weaken this afternoon and clouds will mix
out of most of the valleys, but clearing may not occur at all areas
within 5 miles of the coast, especially in orange county. Marine
layer clouds will spread back inland this evening and reach the
foothills overnight with clouds and fog in the cajon pass and the
san gorgonio pass. There may be areas of drizzle tomorrow morning.

On Thursday night a trough deepening off the ca coast will bring
back stronger onshore flow and an even deeper marine layer to around
5000 feet. Drizzle is again possible Friday morning. On Friday night
and Saturday, a 500 mb vort MAX rounding the base of the trough will
deepen the marine layer even further, which may trigger areas of
light rain west of the mountains. Saturday will be the coolest day
with MAX temps 10-15 degrees below average in the valleys, mountains
and deserts. Skies will be mostly sunny in the deserts and in the
mountains above the marine layer Friday and Saturday, with gusty
westerly winds both days.

Sunday through Wednesday: the trough moves slowly inland Sunday with
weak high pressure aloft bringing warmer days and a shallower marine
layer Monday and Tuesday. But another trough Wednesday through
Friday means that we will end may with gray and start out june with
gloom.

Aviation

occurred inland but much of the coastal areas and some inland areas
remain covered with low clouds. Bases are currently sct 1500-2000
feet msl and bkn-ovc 2000-3500 ft msl with tops to 4000 ft msl. Low
clouds will fill the coastal basin tonight after 03z, with similar
bases and tops. CIGS 1000-2000 ft msl are likely at times between

Mountain crests desert mountain slopes deserts... Mostly clear skies
with unrestricted vis through tonight. Some cumulus clouds have
developed over the higher mountains. West winds gusting 25-35 mph
through mountain passes late this afternoon and evening.

Marine
No hazardous marine conditions are expected through Sunday.

Occasional wind gusts 20-25 knots are possible over the outer waters
during the afternoons and evenings Friday and Saturday.

Beaches
A long-period south swell will continue to produce elevated surf and
hazardous swimming conditions through Thursday, mainly in orange and
northern san diego counties. Swells and surf will begin subsiding
late Thursday. Check the surf zone forecast and the beach hazards
statement for details.
