Synopsis
A santa ana weather pattern will bring warm, dry weather this week
with gusty northeast winds in the mountain passes and inland valleys
at times. Over the weekend an upper level trough off the coast will
bring increasing clouds and a chance for showers Sunday into Monday.

Discussion For extreme southwestern california including orange...

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

the santa ana is fading this evening with weather observations
showing lighter winds and higher humidities than on Monday evening.

Peak wind gusts this evening ranged from 30-40 mph in the wind prone
areas including 35 mph at the san bernardino airport, sill hill in
san diego county, and highland springs in riverside county.

Dew points have rebounded in all areas this evening. The recovery
near the coast has been quite remarkable. At 7 pm the dewpoint at
oceanside was 55 degrees, an increase of 47 degrees over the past 24
hours. Welcome back, onshore flow. Farther inland the moisture
increase was more subdued. Ontario's dewpoint was a mere 12 degrees,
an increase of only 9 degrees in the past 24 hours.

This santa ana synoptic pattern will remain relatively unchanged
this week with a quasi-stationary upper low drifting from arizona to
utah, and a surface high over the great basin. Offshore flow will
continue all week with warm, dry days in all areas. Gusty ene winds
will continue in the mountains, passes and inland valleys, but not
nearly as strong as they were on Monday. Humidities will slowly
recover as moisture wraps around the upper low into southern
california. The IR loops shows mid and high clouds moving in from
the northeast this evening.

Over the weekend a weak upper level trough develops off the southern
california. Models attempt to draw mid-level moisture into the
region for possible showers in the mountains and deserts of san
bernardino and riverside counties, but precip chances are small at
this time.

Aviation
170330z... Clear skies across the area with light winds through
tonight. Generally weak offshore flow tomorrow, with a brief period
between 19-01z Wed when localized N winds 10-15 kts, gusting to 15-
20 kts are likely at kont, ksbd, and ktrm. Aside from this, no
impacts are expected at any of the terminals. Skies will remain
clear in all areas through Thu with weak winds.

Marine
No hazardous marine weather is expected through Saturday.

Fire weather
The red flag warning expired at 8 pm. Gusty northeast winds will
continue in the mountains, foothills and eastern valleys through
Friday. The humidities will not be quite as low as they were on
Monday when they were in the single digits, but they will still be
fairly low and range from 15-25% each afternoon. The fire threat
will be elevated this week, but remain below red flag warning
criteria.

Skywarn
Skywarn activation will not be needed this week.

Sgx watches warnings advisories

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.
