Synopsis
The heat will peak today. For Thursday and Friday, a weak trough
of low pressure will bring a cooling trend with high temperatures
on Friday around average. High temperatures around average will
then follow for the weekend into the first part of next week. Very
patchy low clouds this morning will become more widespread during
nights and mornings for coastal areas into the far western
valleys at times for Friday through early next week. There remain
small chances for some influx of monsoonal moisture for the
weekend into early next week.

Discussion For extreme southwestern california including orange...

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

Short term (today through Friday)
The heat will peak today with high temperatures in most areas a
few degrees warmer than Tuesday. A weak trough of low pressure
will bring a cooling trend for Thursday and Friday with Friday
high temperatures around average in the deserts and a little below
average elsewhere.

The marine layer is shallower, around 1200 feet deep early this
morning, with patchy stratus along portions of the southern and
central san diego county coast. The marine layer will deepen
slightly for tonight into Thursday with low clouds spreading
locally inland near the coast. Deepening of the marine layer is
expected to continue into Thursday night and Friday morning with
more widespread coastal low clouds spreading into the far western
valleys.

Long term (Saturday through Tuesday)
There is not much change to the forecast for the weekend through
early next week. High temperatures will generally fluctuate
around average with night and morning coastal low clouds spreading
into the far western valleys at times. At least a minor intrusion
of monsoonal moisture will bring a few high clouds at times and
some clouds near the mountains in the afternoons. There remain a
small subset of models and their ensemble members that support a
little greater influx of monsoonal moisture for Sunday into early
next week. This would decrease inland high temperatures some, with
more clouds. With enough influx of moisture, there could also be
small chances for precipitation, mainly near the mountains in the
afternoons.

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.
