Synopsis
A weak trough near the california coast will continue the slow
deepening of the marine layer into Saturday. Areas of nocturnal
marine clouds will spread farther into the valleys, but should clear
back to the coast each day. Warmer after Saturday as high pressure
to the east builds, with an influx of monsoonal moisture. Chances
for afternoon thunderstorms will begin on Monday, mainly near the
mountains, with chances peaking about Wednesday. The marine layer
will become shallower into the weekend, with more coastal fog
possible each morning.

Discussion For extreme southwestern california including orange...

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

marine stratus was solid in satellite imagery early this morning. It
covered the ca bight, and extended inland 25 miles. Some patchy high
clouds were visible as well. Westerly winds were quite gusty
overnight in onshore wind-prone areas of the passes, deserts, and
mts with peak gusts 45-50 mph. The sfc pressure gradients were a bit
stronger onshore, helping to fuel the winds. Those winds will
decrease this morning, then pick-up again late in the day and
overnight.

A weak trough just off the coast will deepen slightly today,
maintaining vigorous onshore flow and a slight deepening of the
marine layer. This, in conjunction with below average sea temps well
off the coast, will keep our daytime temps below average through
Saturday. Warming will begin on Sunday as high pressure aloft builds
westward, nudging the trough out of the picture. Models show the
center amplifying northward through Tuesday and peaking over the
great salt lake at around 597 dm. The clockwise gyre it will create
will scoop moisture out of the rio grande valley and transport it
westward and eventually northwestward into socal. The moisture is
forecast to peak here about Wednesday, then trend down as the high
weakens slightly and drifts closer to us. By Friday, the center could
be over SW az. This will keep it quite hot over the deserts and
decrease the chance for convection over our mts deserts late next
week.

The chance for precipitation enters the forecast in the mts deserts
on Mon afternoon and continues each afternoon evening through
Thursday. After that, the proximity of the upper high and moisture
trajectory become less favorable for any thunder over SW ca. Onshore
flow and the marine layer should prevail throughout, although rather
shallow. This will keep coastal areas seasonally mild and likley
with areas of late night morning fog some days. The deserts will be
seasonally hot, but added moisture should hold daytime MAX temps
close to average. Interior valleys will begin to heat up after
Saturday with daytime temperatures back to average on Sunday, and
edging higher into the middle of next week. Looks like summer has
arrived.

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.
