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
Weak low pressure will alternate with weak high pressure this
coming week. Cooler with more coastal clouds this weekend, warmer
with less coastal cloudiness Monday through Wednesday, then
cooler with more coastal clouds later next week.

Discussion For extreme southwestern california including orange...

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

the coastal eddy was king today, holding clouds firmly over coastal
areas in typical "june gloom" fashion. At 8 pm pdt... Clouds were
beginning to expand farther inland and were solid offshore. The 00z
miramar sounding had a marine layer just over 2k ft deep and topped
by a massive 12c inversion. Surface pressure gradients ksan to the
deserts had increased to 6-9 mbs, with a corresponding increase in
westerly mtn desert winds. Peak gusts at 8 pm pdt were 30-35 mph in
onshore wind-prone areas. No forecast changes this evening.

From previous discussion...

the coastal eddy we've got spinning out there is a textbook
specimen of what a coastal eddy should be. It has produced brisk
southerly winds along the coast, prevented clouds from clearing
in coastal areas (not just beaches), and even produced spotty
drizzle this morning. It is poised to push the clouds inland
early this evening to fill nearly all of the valleys overnight.

Temperatures at 1 pm are 3 to 15 degrees lower in all areas from
yesterday's temps at this time. The eddy and cooling trend come
courtesy of a low pressure trough moving through the interior
west. In addition, a tepid gulf surge brought dew points up and
temps down in the lower desert, insomuch that daggett in the high
desert is our unusual hot spot today at 105 so far. The coastal
eddy will continue into Sunday for a very similar day. The marine
inversion weakens a bit Sunday, so there should be just a little
more sunshine at the coast. High pressure aloft rebuilds Sunday into
Tuesday across the southwest, which will bring warmer weather to all
areas and a diminished marine layer. Coastal clouds will probably
not make it into inland valleys Tuesday through Thursday mornings.

Temperatures will head back above average inland on those days. A
low pressure trough will deepen in timid june fashion across the
west Thursday into next weekend. That will reverse the trends,
bringing down daytime temperatures and extending the coastal clouds
into the valleys each night and morning. A weak trough and a weak
ridge continue to jockey for position over southern california next
weekend, but the result will be little variation around seasonal
weather.

Aviation
240325z... Coast valleys... Low clouds spreading inland with ovc cigs
around 1500 ft msl and tops to 2500 ft msl. Low clouds likely to
spread up to 25 miles inland by 12z sun. Bases could lower to around
1000 ft msl with tops to 2000 ft msl but confidence is low. All
coast and valley airports will likely be impacted by low cigs. Areas
of vis 1-3 sm in br hz in the valleys between 10-17z Sunday.

Clearing to the coast may be a little quicker Sunday morning...

approximately 17-20z but low clouds may still linger at the beaches
into Sun afternoon.

Mountains deserts... Mostly clear with unrestricted vis through
Sunday evening.

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.
