Version 3.4
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
Weakening high pressure aloft will bring slightly cooler weather
inland this weekend, while seasonal weather and periods of marine
clouds continue west of the mountains. Warmer again early next week
as high pressure rebuilds. A stronger trough is forecast to develop
over the west later next week for additional cooling and continued
dry weather with more extensive marine clouds.

Discussion For extreme southwestern california including orange...

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

the marine stratus had already made a decent run inland along the
san diego county coast this evening, including southern orange
county. The 00z miramar sounding had a 9c marine inversion based
near 1350 ft msl. This was 300+ ft lower than yesterday evening,
which was reflected in lower ceilings over coastal sites over
northern san diego county and points north. Onshore sfc pressure
gradients to the NE at 8 pm pdt were weaker than yesterday evening
as well. Perhaps the lack of a coastal eddy and the weaker onshore
forcing have contributed to the lowering of the marine layer this
evening.

It was hot in the deserts today where temperatures reached 116f at
palm springs and 114f at borrego springs. Even high desert areas
peaked over 105f. The excessive heat warning is no longer in effect.

Not as hot on Saturday with continued cooling on Sunday.

An eddy is forecast to spin up again overnight, coupled with an
overall lowering of heights. This should help prop the marine
layer back up Saturday morning. Typical june weather is expected
with seasonal temperatures, except over the high deserts and
mountains where MAX temps will still be several degrees above
average. The zone forecast was updated at 8 pm pdt.

From previous discussion...

low clouds extended pretty far inland this morning for the kind of
high pressure we have pressing down overhead. That high pressure
has boosted temperatures in the desert today with the excessive
heat warning valid through sunset. So far (as of 1 pm) palm
springs and thermal have shot up to 109 degrees with no signs of
slowing down. A trough of low pressure moves slowly through the
interior west this weekend. That will help generate a coastal eddy
tonight, but the extent of clouds each night and morning will be
similar to this morning. Temperatures west of the mountains will
decrease a little, but mountain and desert temperatures will drop
5-10 degrees Saturday and an additional 5-10 degrees Sunday. It's
possible the marine inversion will remain strong enough to prevent
much beach clearing, but at least partial clearing is expected.

On Monday and Tuesday high pressure aloft builds over the
southwest again, but not to the level of the past few days. So it
will be warmer inland, but not dangerously hot. The marine layer
will be shallower and the nocturnal clouds confined closer to the
coast. Wednesday and Thursday the guidance shows a western trough
developing. So after a few more hot inland days early next week,
we'll get noticeably cooler weather for the latter half of the
week. The coastal low clouds will probably fill most if not all of
the coastal basin those nights. Small fluctuations in our early
summer weather pattern.

Aviation
230400z... Coast valleys... Ovc010 tops 020 msl spreading 25 miles
inland through 14z with fog haze vis restrictions of 3-5 miles at
kcrq and 1-3 miles at kont and ksbd between 11-17z Saturday.

Clearing to the coast Saturday morning between 16-19z.

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