A few light showers this afternoon, mainly in san diego county. Another
round of showers is expected late this afternoon and evening,
ending late tonight. Snow levels will be 4000 to 4500 feet. Cool
today with southwest to west winds gusting to 45 mph on the
desert slopes of the mountains. Dry and warmer Sunday through
Tuesday. A low pressure system over the eastern pacific could
bring rain to areas bordering los angeles county on Wednesday with
greater chances for rainfall across much of southwest california
for Thursday into early Friday.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino

the showers have mostly dissipated but a few remain this
afternoon, mainly in san diego county. So far, the location with
the greatest amount of rainfall is located on palomar mountain at
1.07 inches. Several other locations have reported amounts of 0.75
inch or greater. The snow level is between 4500 and 5000 ft and
amounts of up to 7 inches have been reported in the san bernardino
mountains. A second shortwave approaching from the northwest will
bring another round of organized precip to the region late this
afternoon evening, before moving away to the east late tonight.

Total rainfall will range from two tenths to one inch near the
coast and one half to one and one half inch in the mountains with
locally greater amounts.

In the mountains, snow levels 4500 to 5000 feet this afternoon
will lower to around 4000 feet late tonight. Total snow
accumulations of a trace to 1 inch are expected between 4000 and
5000 feet, 2 to 5 inches from 5000 to 6000 feet, and 5 to 7 inches
above 6000 feet with local accumulations to 10 inches on the
highest peaks of the mountains in san bernardino and riverside

Gusty southwest to west winds will continue into tonight with,
gusts to 45 mph from the mountain ridge top onto the desert slopes.

Strongest gusts to 55 mph are expected for this evening along the
east slopes of the mountains from the san bernardino mountains

For Sunday through Tuesday... High pressure aloft will build over
california with a low pressure system farther off the coast,
centered along 140w. This will bring dry weather with a warming

For Wednesday through Friday... Deterministic models still show
some differences in solutions and the forecast favors the
solutions from the ECMWF and canadian models. This would bring an
initial round of more significant precipitation for central and
northwestern portions of southern california for Tuesday night
into Wednesday. Some of that precipitation might extend into areas
bordering los angeles county on Wednesday. As the upper trough
off the west coast begins to move eastward... More significant
precipitation would spread across much of southern california
Wednesday night and Thursday... Decreasing early Friday.

1172015z... Mountains westward... Sct-bkn cloud layers 3000-5000 ft msl
with higher layers to near 10000 feet msl through about 18 1000z
Sunday morning, and isolated showers. Showers and bkn clouds mainly
near ksan in the south, and about 5-10 sm east of the coastline
elsewhere through 18 0200z this evening, becoming more widespread
overnight after about 18 0200z.

At ksan the risk of bkn-ovc low cloud bases below 2500 feet msl is
low so confidence in the higher bases per the TAF is moderate-high.

Desert mountain slopes deserts... West winds 20-30 kt with gusts to
45 kt through 17 2300z-18 0600z with strong uddfs and wind shear.

West-northwest winds 15-25 kt developing this evening through Sunday
morning. A small craft advisory is in effect from 7 pm this evening
through 4 am Sunday.

Showers will continue at times today through Sunday morning.

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

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
