Synopsis
Cooler weather is in the forecast through Friday as a weak trough
of low pressure moves through the region. Low clouds will spread
farther inland each day as the marine layer deepens. It will be
windy in parts of the mountains and deserts. There is a slight
chance of light showers from the coast to the foothills Thursday
night into Friday morning. High pressure will rebuild over the
west this holiday weekend for warmer weather and a shallower
marine layer.

Discussion For extreme southwestern california including orange...

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

coastal low clouds have been slowly advancing overnight, but not
much if at all into the valleys. Some high clouds will continue to
move across our sky coming from a weak low over the pacific to our
west. A fair and cooler day is expected as a low pressure trough
bears down from the north and merges with that pacific low today
and tonight. That will deepen the marine layer and extend the low
clouds into the valleys. It will also boost winds in the mountains
and deserts. Small portions of this region will have strong winds.

An advisory is in effect for gusty pockets in the northern
coachella valley and the anza borrego desert late this afternoon
into Friday morning. The trough will deepen further Thursday and
a shortwave will move through southern california Thursday night
into Friday morning. As the marine layer gets stretched out in the
vertical, some light showers could result. Friday will be
unseasonably cool with highs in the 60s west of the mountains, 50s
and 60s in the mountains, and 70s and 80s in the deserts. The
trough moves off and allows for some half-hearted ridge to build
through the holiday weekend. The marine layer will gradually
shallow while daytime temps will gradually rebound to slightly
above average on memorial day. That means 70s near the coast and
in the mountains, 80s and lower 90s in the inland valleys and
high desert, and back over the century mark in the lower deserts.

A weak trough appears on the horizon next week which would bring
slightly cooler weather and more extensive coastal clouds.

Aviation
240900z... Coast valleys... Widespread stratus near the coast and
about 10 sm inland with bases 400-800 ft msl continuing through mid
morning. Areas of vis 3-5 sm over higher coastal terrain and down to

16-18z. Bases lifting to 1000-1500 this evening, reaching the
coastal airports 03-06z and spreading into the inland valleys
overnight.

Mountains deserts... A few high clouds and unrestricted vis through
thu morning. Onshore winds becoming strong after 00z this evening
with gusts through the mountains and along the desert slopes up to
45 kts along with mdt up downdrafts... And patchy blowing dust sand
in the deserts.

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.
