Offshore flow will strengthen tonight and bring strong northeast
winds through and below passes and canyons through midday Saturday.
High pressure aloft will bring dry, warm weather next week with
temperatures averaging a little above normal. Some coastal low
clouds will return early next week.
Discussion For extreme southwestern california including orange...
san diego... Western riverside and southwestern san bernardino
surface pressure gradients have trended more strongly offshore the
past 8 hours. At noon the san-tph gradient was -3.6 mb, and at 8 pm
it was -8.8 mb. North winds have advected the dry airmass into the
high deserts where the dew point at apple valley was 6 degrees at 8
pm and the winds were NE 12g21 mph.
The WRF and cansac models continue to show strong santa ana winds
surfacing across the mountains and foothills between 05-09z with the
strongest winds between 09-18z Saturday. The offshore flow will be
strong enough to reach coastal orange county where downslope
adiabatic warming will reach the beach. As a result, temperatures
there will probably be above guidance, and temps were raised several
degrees near the coast. Huntington beach, newport beach and laguna
beach all have a good chance to crack 80 degrees. No changes to the
remainder of the forecast.
*from previous discussion*
we will be under a strong north-northwest flow pattern through
Saturday, and this will combine with a surface high building over
the great basin and a stable layer in the 800-700 mb layer for the
mountain wave to bring santa ana winds to some areas, especially
below the cajon pass and in orange county where local gusts over 60
mph are likely late tonight and Saturday morning. Some moderately
strong winds will occur in san diego county from the mountain crests
west through the foothills, with local gusts over 50 mph there.
Winds will decrease rapidly Saturday afternoon as the support aloft
decreases as the troughing in the west shifts east and the north
flow aloft weakens. It will be much warmer west of the mountains,
especially near the coast as some temps could be above 90 within 10-
15 miles of the coast, with highest temps in orange county. 850 mb
temps will be several degrees higher Sunday, but onshore flow will
prevail by then, so mountains and deserts will be warmer, but
coastal areas will cool.|
Next week, the high pressure ridge will slowly move from west to
east over california, with weak to moderate onshore flow at the
surface. Low clouds and fog will return to the coast probably Monday
night, possibly as early as Monday morning. Temperatures will
average a little above normal, especially in the inland empire,
mountains and deserts where the warm profile will be less affected
by the coastal marine layer. Some lower desert locations could reach
100 wed/thu. Some cooling could occur late in the week as the upper
high moves east and a weak pacific trough approaches the west coast.
290345z... Decreasing clouds AOA 20000 ft msl and unrestricted vis
through Saturday evening. Strong north to northeast winds will
develop s/sw of the mountains, including north portions of the
coachella valley, and below the passes and canyons 06-20z. Local sfc
gusts 35-50 kt, stg-svr uddfs, and llws are likely through Saturday
afternoon. Winds will gradually weaken late Saturday afternoon and
Northwest wind gusts of 25-30 kt will continue through early
Saturday. A short-period, choppy swell from 290 degrees peaking this
evening at 9-11 feet will diminish tonight and Saturday. A small
craft advisory continues through early Saturday morning. Northwest
winds will increase again Saturday evening and may briefly pose a
hazard to small craft.
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
