Synopsis 19 724 pm.

Cloud cover will increase overnight as another cold storm system
approaches the area Wednesday into Thursday. It will bring a
chance for showers and low elevation mountain snow along with cold
temperatures and gusty winds. Dry conditions return Friday through
early next week and temperatures will begin to warm up.

Short term (wed-sat) 19 816 pm.

Mostly clear skies with another round of cool temperatures
overnight. Frost advisories in effect for the central coast,
ventura county valleys, santa clarita valley, and western portion
of the san fernando valley.

Cold storm system will impact the region Wednesday into Thursday
night. The system will have a mostly over-land trajectory so
moisture will be limited. However, it is a very cold air mass and
the main impact of this system will be the very low snow levels
and its effect on roadway travel across the region. In fact, this
system will likely bring the lowest snow levels we have seen so
far this season, as thickness values are expected to fall to
between 525 and 528 dm across southwest california on Thursday.

The coldest air aloft will move into the region on Thursday, when
the 530 dm low center moves into la county in the afternoon. 500
mb temperatures are expected to fall to around -35 degrees
celsius! This very cold air aloft will help to destabilize the
atmosphere on Thursday, bringing the threat of brief heavy
downpours, small hail, and even a slight chance of thunderstorms.

This system will be showery in nature, with a chance of showers
beginning across san luis obispo and santa barbara counties
on Wednesday morning, spreading into ventura and los angeles
counties by Wednesday afternoon or evening. Rainfall amounts are
generally expected to be less than 0.25 inches across
coastal valley areas, with between 0.25 and 0.50 inches across
foothills and mountains. However, there will likely be locally
higher totals for areas that receive the brief heavier showers or
thunderstorms.

Snow levels are expected to range between 3000 and 3500 feet on
Wednesday, falling to between 2500 and 3000 feet Wednesday night,
and eventually lowering to between 2000 and 2500 feet on Thursday.

Snow levels will locally fall to 1500 feet or lower on Thursday
with any convective shower activity. Snow amounts are generally
expected to range between 1 to 3 inches for the mountains and
foothills above 2500 feet, except local 3 to 6 inch accumulations
possible for the eastern san gabriels. Elevations between 1500 and
2500 feet (including the antelope valley, cuyama valley, san luis
obispo interior valleys, santa monica mountains, higher valleys of
la ventura counties, and coastal foothills) could potentially see
a dusting to minor accumulations of snow. Winter weather
advisories will be issued for all mountains, antelope valley,
cuyama valley, and san luis obispo county interior valleys where
there will be a higher probability of accumulating snowfall. Major
low elevation roadways at risk for snow showers and icy road
conditions with this event include interstate 5 from the grapevine
to santa clarita valley, highways 14 and 138 through the antelope
valley and soledad canyon, highway 33 above ojai, highway 154
above san marcos pass, highway 166 through cuyama valley, and
highways 41, 46, and 58 across interior portions of slo county.

*** from previous discussion ***
by Friday the system has moved to arizona and we will see a
little ridge will pop up with heights rising to about 560 dm.

Friday will be a sunny and cool with MAX temps still in the 50s.

Long term (sun-wed) 19 250 pm.

A general warming trend for Saturday through Tuesday. By Sunday
the 500mb heights will be back up to about 564 in cool and dry
northwesterly flow. By Monday the ec starts digging another upper
low into the western us while GFS is more zonal. Its a long way
out to take either very seriously and in either case the skies
will be mostly clear to partly cloudy and MAX temperatures will
warm a bit.

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.
