Synopsis
Below normal high temperatures and a deep marine layer will
continue through Thursday. Patchy drizzle is expected again over
portions of the coast and valleys Thursday morning. High pressure
building this weekend will bring much warmer weather next week.

Discussion For extreme southwestern california including orange...

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

those clouds just didn't clear. If you were at the coast or
western valleys of san diego county or the southern oc, you didn't
get even a peek at the sun. That made low and high temperatures
interesting, ranging a whole two degrees for many spots. The sun
did come out in northern oc and the rest of the region. Cumulus
clouds flecked the skies in the mountains and desert, reminding us
there's some monsoon flow in the air, but no showers or
thunderstorms resulted. No, those happened in the mojave desert
north of barstow and around las vegas. A weak low pressure trough
continues to spin overhead and prop up our stubborn marine layer.

It's difficult to see Thursday being much different than today
was, along with isolated drizzle in the morning. The kind of
marine inversion that develops overnight will let us know the
chances of full clearing or not. The trough will gradually fizzle
out Friday as high pressure builds aloft across the west. That
will bring much warmer weather while squashing the marine layer.

By Sunday, temperatures will start exceeding 100 in the inland
empire and high desert, 110 in the low desert, and mostly 80s and
90s closer to the coast. This kind of heat will continue through
Tuesday or Wednesday before that upper high begins to break down
to allow for any cooling. And right now it doesn't look like a
quick and meaningful cooldown. With the high pressure ridge
centered over the interior west, the easterly flow underneath it
will create a monsoon flow into our region. Extended model
guidance shows a small chance of showers and thunderstorms, almost
convincing enough to justify adding that chance to the forecast.

Less moisture after Wednesday should keep any chance near zero.

Aviation
240305z... Coast valleys... Widespread low clouds with bases 1500-2000
ft msl will continue through tonight, spreading into the valleys and
possibly reaching kont and ksbd around 10z. Vsby restrictions 2-4 sm
at times where clouds and terrain intersect. Partial clearing is
expected between 17z and 19z Thursday, although any clearing at ksan
and kcrq is doubtful.

Mountains deserts... Mostly clear with unrestricted visibility
through Thursday morning. Sct clouds with bases around 10000 ft msl.

Gusty west winds Thursday afternoon and evening over the mountains
and desert slopes with gusts to 35 knots at 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.
