area forecast discussion
national weather service san diego ca
955 pm pdt Thu mar 23 2017

Synopsis
It will be warmer and dry Friday, then precipitation chances return
Saturday as a weak system moves across the area. Another system
could create showers Monday or Tuesday, then dry weather and above
normal highs develop for the middle of next week. Gusty westerly
winds will develop over the mountains and deserts as each system
moves across the region.

Discussion For extreme southwestern california including orange...

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

Evening update...

a transitory ridge pattern will bring warmer weather on Friday with
fair conditions. The next weather system will arrive on Saturday as
an upper level wave moves through and the ridge shifts east. No
major changes were made this evening to the ongoing forecast
database.

Previous discussion was issued earlier today at 143 pm pdt...

the aforementioned ridge will build over the area Friday and help
rebound high temperatures to near normal. The ridge quickly gets
squashed by an upper-level trough Saturday, lowering highs back to 5-
10 deg f below normal, and increasing chances of showers. Coverage
and strength of showers looks minimal for now as most of the
instability and moisture remain to our north. Showers will begin
over northern areas Friday night, and spread SE Saturday morning and
afternoon. Accumulations are expected to be very light, with highest
amounts near one-tenth of an inch expected near the mountains. Snow
levels will dip down to 6500 ft Saturday morning, then rise through
the day Saturday with only a dusting expected for higher elevations.

Westerly winds will gust around 35-45 mph over the mountains and
deserts late Saturday. Dry weather will develop Sunday under zonal
to NW flow flow aloft.

Another system will move across the region sometime Monday-
Tuesday, however models disagree with timing and precip amounts.

For now, will maintain slight chance of precip on Monday and
Monday night, with snow levels above 7000 ft Monday morning then
down to 5500 ft Monday night. Gusty westerly winds are expected
over the mountains and deserts, with gusts to 40-50 mph. Weak
ridging aloft will develop for the middle of next week, helping to
raise highs to slightly above normal. Weak offshore flow is
possible as surface high pressure builds over the great basin.

Aviation
240350z... Sct-bkn clouds along the coastal slopes gradually clearing
overnight. Otherwise mostly clear with unrestricted vis through
Friday evening. Patchy stratus with bases near 2000 ft msl
developing after 25/03z.

Marine
No hazardous marine weather is expected through Saturday morning. A
trough moving through on Saturday will bring gusty west-northwest
winds gusting to near 20 kt, rough seas, and scattered light
showers. No hazardous marine weather is expected Saturday night
through Tuesday.

Skywarn
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

Sgx watches/warnings/advisories

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.
