Synopsis
High pressure aloft will continue dry weather today with near to
slightly above average high temperatures. Monsoonal moisture will
gradually increase during the weekend returning a slight chance of
afternoon and early evening thunderstorms to the mountains and
deserts. For early next week... Easterly flow aloft will bring
increasing monsoonal moisture with more clouds... Continuing
chances for afternoon early evening thunderstorms for the
mountains and deserts... And smaller chances for showers and
thunderstorms at other times and for other areas. Some drying and
warming may occur late next week.

Discussion For extreme southwestern california including orange...

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

Short term (today through Sunday)
A weak trough of low pressure is off the northern and central
california coast with high pressure aloft to the east centered
across arizona and new mexico with the axis of high pressure aloft
extending across northern baja. This axis of high pressure will
shift slowly towards the north through the weekend allowing for a
slow influx of monsoonal moisture. Some afternoon clouds are
expected near the mountains for the weekend with small chances for
afternoon thunderstorms.

Satellite imagery early this morning shows areas of coastal
stratus extending into the western valleys. Coverage is expected
to become patchier this weekend as the monsoonal moisture slowly
increases.

Long term (Monday through Thursday)
High pressure aloft will shift northward with the flow aloft
becoming easterly across southern california. This will bring a
greater influx of moisture with more clouds... Continuing chances
for afternoon and early evening thunderstorms for the mountains
and deserts... With smaller chances for other areas and at other
times.

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.
