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
High pressure aloft will bring a few degrees of additional warming
today with the heat peaking today. Weakening high pressure aloft
and stronger onshore flow will bring about 5 degrees of cooling
for inland areas on Saturday and another 5 degrees on Sunday. This
will be followed by slow warming for the early part of next
week... Then gradual cooling the for the latter half of next week.

The marine layer will keep coastal areas cooler with areas of
night and morning coastal low clouds and fog extending inland into
the western valleys... Except farther into the inland valleys for
late Saturday night into Sunday morning.

Discussion For extreme southwestern california including orange...

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

Short term (today through Sunday)
High pressure aloft centered over northern baja will bring a few
degrees of additional warming with the heat peaking today.

The marine layer is near 1500 to 2000 feet deep with satellite
imagery showing widespread stratus over the coastal waters
extending inland across about the western half to two-thirds of
the san diego county valleys... And into the western and southern
portions of the inland empire. Similar coverage is expected for
tonight into Saturday morning.

For the weekend... High pressure aloft will weaken and shift
southward as a low pressure system moves inland through the great
basin. This will strengthen the onshore flow which will spread
cooling inland. Inland areas will cool around 5 degrees on
Saturday and another 5 degrees on Sunday. The marine layer will
deepen with coastal low clouds extending farther into the inland
valleys for late Saturday night into Sunday morning.

Long term (Monday through Thursday)
Weak high pressure aloft will move across southern california
early next week. This will bring a slow warming trend from Monday
through Tuesday or Wednesday with Tuesday and Wednesday not quite
as hot for inland areas as today. A trough of low pressure will
develop near the west coast late in the week with a cooling trend
for Thursday into next weekend. Areas of night and morning
coastal low clouds and fog will extend inland into the western
valleys.

Aviation
220925z... Coast valleys... Low clouds with bases 900-1500 ft msl and

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
