Synopsis
A few more isolated rain and snow showers could develop late this
afternoon or evening, otherwise sunny to partly cloudy skies today
and much cooler. The low pressure trough responsible will move east
on Tuesday, but several more weaker systems will slide south over
the region during the latter half of the week, keeping temperatures
below average, and possibly sparking more periods of scattered,
light showers. The winds will continue strong and gusty through this
evening, then weaken late tonight. Continued quite cool on Tuesday,
followed by slight warming midweek. Dry and a little warmer next
weekend.

Discussion For extreme southwestern california including orange...

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

satellite imagery this morning showed clearing pushing inland from
the coast. Clouds remained over the mts, and there were more cold
cumulus drifting SE well offshore. The 12z miramar sounding had a 4
degree c inversion based near 5500 ft msl with 24 hour cooling below
of 5 to 7 degrees c. The sounding was quite dry as well with a pw of
only 0.31 inch. Surface pressure gradients were running around 10
mbs onshore ksan to SW nv and 6-8 mbs to the lower deserts. Peak
westerly wind gusts at 8 am pst were 45 to 60 mph in the onshore
wind-prone areas of the san diego mts, but many areas were gusting
25 to 30 mph this morning at lower elevations too. Based on sfc
obs... The snow level was 3000-3500 ft. Radar still had some weak
returns over the mts, moving rapidly east. A statement for peak wind
gusts and accumulated precip is headlined on our web page.

Precip amounts have been very light.

The forecast has been updated to remove pops at lower elevations of
the CWA for the remainder of today. MAX temps may be a tad underdone
given all of the sunshine this morning, but the airmass is quite
cold so don't look for much of a temp increase through the day, and
the gusty winds will make it feel even cooler.

From previous discussion...

a large cold low pressure system will remain over the western
states in the eastern pacific into next week... But it will be
weaker during next weekend.

There have been scattered light showers overnight along and west
of the mountains with amounts ranging from nothing to a few
hundredths near the coast... To locally one to two tenths of an
inch in the mountains. Coverage has been pretty limited... But
greater such as it is along and near the coastal slopes of the san
bernardino county mountains... And for portions of san diego
county. Showers are expected to decrease through early this
morning. Additional light showers are possible for this afternoon
and evening... Mainly near the mountains with snow levels near 3500
feet.

Strong gusty west winds in the mountains and deserts will
gradually diminish a little from north to south during the late
morning through afternoon. Gale force winds across the coastal
waters will spread gusty west winds across san diego county
coastal and valley areas today.

It will be much cooler today with high temperatures 15 to locally
25 degrees cooler than Sunday... 15 or more degrees below average
for most areas except right at the coast. Cold nights will follow
for tonight and Tuesday night as winds weaken with areas of frost
in the valleys.

The global models are in generally better agreement through next
weekend near the west coast. This will maintain well below average
high temperatures through Friday with additional chances for
showers along and west of the mountains for Wednesday afternoon
into Friday evening with snow levels remaining fairly low.

High temperatures will warm a little for next weekend... But remain
below average.

Aviation
191615z... Coast and valleys... Isolated showers through 18z. Sct-bkn
clouds with bases at or above 3500 feet msl and unrestricted vis
through 06z tue. Mostly clear with unrestricted vis after 06z tue.

Areas of west winds 20-30 kt will occur near the coast through about
00z Tue and will likely bring occasional gusts over 30 kt at ksan.

Winds weaken after 00z tue.

Marine
Northwest winds with gusts 30 to 40 kts and hazardous seas will
continue through tonight. See the marine weather message and coastal
waters forecast for details. No hazardous marine conditions are
expected Tuesday into Thursday, but hazardous winds and seas are
likely again late Thursday and Friday.

Skywarn
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.
