High pressure over the great basin will bring weak to moderate
offshore flow to southern california through Wednesday. These santa
ana conditions bring warm days and comfortably cool nights. Winds
will be gusty at times in the mountains and foothills. Dry and
warmer Thursday and Friday with lighter offshore winds.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
aside from a band of mid-level clouds over the san diego mountains
and eastern deserts, skies were clear this morning. The marine layer
was non-existent, and the closest low clouds were south of ensenada.
Santa ana conditions produced locally gusty winds in the mountains,
foothills and passes this morning, strongest san bernardino and
riverside counties, and the santa ana mountains where 10-20 mph
winds were gusting to 30-35 mph. Winds were lighter in san diego
county. The santa ana airmass has reached all the way to the coast
this morning where dewpoints were in the 30s and low 40s. Farther
inland the dewpoints were lower, ranging from the teens to the low
Both the ECMWF and GFS model are consistent with the santa ana
weather pattern this week. A longwave trough over the west will be
reinforced by a shortwave dropping south over nv tomorrow. This
shortwave will develop into a cut-off low over the lower colorado
river valley Wednesday. The trough then lifts NE on Thursday and
Friday with higher heights resulting in even hotter days to end the
week. The coastal areas may not see a significant temperature change
thu or Fri though, as the marine layer returns in response to a
coastal eddy that will form on Wednesday. Increasing boundary layer
rh will likely bring some marine layer clouds and patchy fog back
into coastal areas during that time.
Long range outlook for the weekend and beyond: the ECMWF and GFS are
at odds with each other. The GFS is forecasting a mean ridge pattern
through early next week, while the ECMWF is suggesting a trough for
stronger onshore flow and a hint of cooling. In either case,
precipitation is unlikely, and the main challenge will be if|
temperatures will be average or above average.
251630z... Mostly clear skies today and tonight. Local northeast
winds in foothills and below canyons into valleys. Expect greater
coverage of offshore winds around 15-25 kt in these areas through
20z today. Local mdt up downdrafts and llws west of the mtns. Kont
and ksbd are most likely TAF sites to be impacted by these winds and
llws. A similar offshore wind pattern will develop early Tuesday.
No hazardous marine weather is expected through Friday.
North-northeast winds in the mountains and foothills ranged from 10
to 20 mph this morning with gusts between 20-30 mph. A few of the
wind prone sites had peak gusts above 30 mph including fremont
canyon (43 mph at 7 am), crestline ridge (41 mph at 2 am), and big
black mountain (33 mph at 2 am). The winds will drop off this
afternoon and evening, then increase again Tuesday morning.
Strongest winds will be in and below the cajon pass and over the
santa ana mts canyons. The winds will be lighter over san diego
county. On Wednesday the winds will a little weaker. Afternoon
humidities will bottom out between 10-15% in these areas today and
Tuesday which will increase the wildfire risk, but limited areal
coverage of these conditions will be too small to require any fire
The will be a small increase in rh Wednesday through Friday, but
overall it will remain fairly dry with afternoon humidities below
25%. It will be dry and very warm days through next weekend,
creating an elevated wildfire risk region-wide. Winds may be gusty
both off and onshore at times, but should be localized and not over
any extended period.
Skywarn activation will not be needed today.

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 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.
