207 am pst Wed dec 13 2017

High pressure aloft and offshore flow at the surface will continue
warm and dry weather into the middle of next week. Stronger santa
ana winds are likely on Thursday and again on Sunday over the
mountains, foothills and passes. Skies will remain fair with very
low relative humidity except near the immediate coast and locally
inland at times with the sea breeze.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino

skies were clear across the CWA early this morning. At 2 am pst...

the sfc pressure gradient from SW nv to ksan was offshore at
almost 12 mbs... And neutral to the lower deserts. Winds 0f 25 mph
with gusts to 35 mph were reported at some of the windier mtn canyon

A strong ridge aloft along 130w is forecast to hold this week as
weak shortwaves drop south into and through the great basin. These
waves will cause the sfc pressure gradient across the SW to
fluctuate from weak onshore, to strong offshore as they pass, with
no significant weather change this week. Very dry continental air
will remain in place across all but the immediate coastal areas.

This pattern will keep daytime highs from 5 to 15 degrees f above
average through Friday, with well above average minimums, except in
wind-sheltered valleys deserts where steep temperature drops are
likely during the long nights.

Not a whole lot of change for the coming weekend and into the
following week as the ridge remains in place. Another shortwave
trough may drop close enough again on Sunday for another round of
gusty offshore winds. Daytime temperature will remain above average.

Fire weather
Weak, to locally moderate offshore flow this morning will turn
onshore by afternoon most areas, except up against the san
bernardino mountains. Rh will remain very low, except along the
immediate coast, where a modest recovery into the 20-40% range is
expected through this evening and overnight.

For Thursday... Offshore flow will accelerate through and below the
passes and canyons, and along the coastal slopes. It will begin early
morning over orange and san bernardino counties, then spread south
along the riverside and san diego county mts, peaking there later
in the day through early Friday morning. A fire weather watch
is in effect for the expected winds and low continued low rh.

Lighter winds are forecast later Friday into Saturday.

For Sunday... Offshore winds may increase and become strong and gusty
again in these wind-prone areas of the mtns and foothills.

131000z... Mostly clear with unrestricted vis today and tonight.

Local surface northeast winds 15-25 knots with isolated higher gusts
will occur at times mainly in the foothills.

No hazardous marine weather is expected through Sunday.

Sgx watches warnings advisories

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
