Synopsis
Fair and seasonal weather will continue this coming week. The
marine layer will continue the coastal clouds nights and mornings.

Lower pressure aloft this weekend into next week will bring cooler
weather for all areas, extend the marine layer and increase
coastal clouds.

Discussion For extreme southwestern california including orange...

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

the coastal clouds moved ashore on schedule last evening, but have
since moved out of san diego in puzzling fashion. That should be a
temporary hiccup and low clouds and fog will cover coastal areas
and some westernmost valleys by sunrise. The cloud bases are
higher, so the coverage of dense fog will be patchier and slightly
farther inland than it was yesterday morning. By late morning
these clouds will clear, but there will be variable high clouds to
occasionally filter the Sun a bit. Temperatures will continue
above seasonal averages except at the immediate coast. Breezy
winds will develop late this afternoon through mountain passes and
into deserts, but with gusts mostly below 35 mph. Take a mental
picture of this description, because that's what Wednesday and
Thursday will be like. If there is any trend, it would be slightly
greater coverage of coastal clouds each night and morning through
Friday, and slightly cooler daytime weather. A low pressure
trough will develop and move into northern california this
weekend. That is projected to deepen the marine layer and bring
even cooler weather with daytime temperatures below average and
brisk winds in the mountain and deserts. A larger long wave trough
circulation over the west will ensure that cooler and cloudier
weather persists as we head into may. There are some hints by
some model guidance for rain Monday and beyond, but recent
performance in the guidance out one week has not been good. The
models keep kicking the rain can down the road an additional day.

The obvious effect is to lower confidence, so we wait for more of
that before forecasting the wet stuff. Until then, keep the
jackets handy.

Aviation
240850z... Coast... Areas of bkn-ovc stratus continuing up to 15 miles
inland this morning. Bases will be 700-1000 ft msl with tops to 1400
ft msl. Areas of vis 3-5 miles will occur over higher coastal
terrain. Stratus clearing over land 16z-18z, remaining locally bkn
along the immediate coast through the afternoon. Stratus will
develop again after 25 02z and spread 15-20 miles inland overnight.

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.
