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.

Synopsis
High pressure aloft will build through Tuesday, bringing warmer
weather and shrinking the marine layer back toward the coast. For the
latter half of the week... A low pressure trough settles over the
west, bringing cooler weather, a deeper marine layer, and more
extensive low clouds west of the mountains.

Discussion For extreme southwestern california including orange...

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

skies were clear across socal this evening, except along the
immediate coast and offshore where marine clouds were slowly
thickening and edging inland. The 00z miramar sounding had an 8c
inversion based near 2150 ft msl with weak SE winds below the
inversion. The eddy has weakened but the sfc pressure gradients
were holding onshore ksan to the deserts at 6-9 mbs. Peak westerly
wind gusts through the desert passes were 30-40 mph.

Even though the eddy has weakened or largely drifted offshore, the
sounding still showed some SE flow below the inversion. Once this is
gone, the marine layer depth will likely decrease overnight. Still
expect low clouds and some fog to make it into the western valley
areas. These clouds should beat a hasty retreat back to coastal
areas by mid to late morning, but may not clear the beaches
completely on Monday as the inversion strengthens. Continued
thinning of the marine layer is possible into Wednesday. The thinner
marine layer will mean much warmer days (closer to average) inland,
as the cooling power of the sea breeze is diminished.

Both the latest ECMWF gfs runs show a longwave trough reestablishing
itself over the west for the latter half of the week. The GFS is the
more robust model, implying more cooling and marine clouds west of
the mts for the upcoming weekend, but at this point the amount of
cooling is uncertain.

Looking ahead to early next week(first week of july)... There is
quite a bit of spread in the model solutions. The ECMWF keeps the
flow largely dry and westerly over socal, while the GFS model builds
the subtropical high over the southern rockies and great plains,
which swings our upper-level winds southerly, allowing some
intrusion of subtropical moisture. Looks like it will take a few
more model runs before we can sort this one out.

Aviation
250330z... Coast valleys... Low clouds beginning to spread inland,
currently impacting ksan and kcrq with bkn-ovc CIGS 1500-2000 ft msl
and tops to 2500 ft msl. Low clouds likely to spread up to 20 miles
inland by 12z Mon with bases lowering to around 1500 ft msl. Cigs
could reach ksna between 06z and 09z. Vis lowering to 3-5 miles in
fg hz at kont and ksbd between 12z-18z Monday but confidence is not
high. Low clouds clearing to the coast 18-21z Monday.

Mountains deserts... Mostly clear with unrestricted vis through
Monday.

Marine
No hazardous marine weather is expected through Thursday.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.
