SYNOPSIS 20 220 AM.

An upper level low pressure system approaching the California Coast will bring significantly cooler and showery conditions today. There will be some mountain snow and a slight chance for thunderstorms today. Showers could linger into Thursday. Most of the precipitation will stay in the southern portion of the forecast area. Drier and warmer conditions will return to the area going into the weekend.

SHORT TERM (TDY-FRI) 20 254 AM.

The first rain of the season is about to arrive, but at the moment it is nothing to write home about. A 541 DM upper low is near Pt Conception. There is not much rain so far. Some light showers over the Central Coast and better shower activity over the south facing slopes of the eastern San Gabriel Vly. The upper low has exploded the marine layer which is now 4000 ft deep. Marine layer stratus now covers most of the coasts and vlys. The best dynamics with this system will be focused from LA county to Orange county with much less shower activity across SLO SBA VTA counties. The best instability is right under the upper low and satellite shows an area of organized convective showers under the low to the west of Pt Conception. This instability will create a slight chc of TSTMs as it translates west to east along the coast of southern SBA county... the VTA county coast and then into LA county around noon. The chc of rain will greatly diminish across SLO and SBA county as well as the VTA county coast in the afternoon.

This system will not be that much of a rain maker. SLO and SBA counties will be lucky to see even a tenth of an inch with not much more expected over VTA county. The best rain will fall over LA county but even there it will be hit or miss. Most coast and vly locations there will see a tenth to a quarter inch of rain.

The exception to this will be the south facing slopes of the eastern San Gabriels where constant upslope flow could produce nearly an inch of rainfall. Rainfall rates will be under a tenth of an inch per hour except under TSTMs which could produce a half inch of rain per hour.

Snow levels will fall to 6000' or lower by mid morning. A winter weather advisory is in effect for the LA mtns, mainly the eastern San Gabriels where up to 6" of snow could fall near resort levels.

It will be a cool day regardless of hour much rain falls most cst and vly locations will struggle to escape the lower 60s.

The rain will taper off tonight and skies will start to clear.

Can't rule out a shower or two over the mtns and all of LA county Thursday morning but it is pretty unlikely. Otherwise the day will be partly cloudy and cool with most coastal and vly highs remaining in the mid 60s.

Better confidence in the Friday forecast now. All mdl solutions keep the wayward upper low well to the west of the state and bring a little pop up ridge over the state. Skies will be partly cloudy as some high level clouds drift overhead. Weak offshore flow and slightly higher hgts will bring a few degrees of warming but almost all areas will see highs under 70 degrees.

LONG TERM (SAT-TUE) 20 303 AM.

EC and GFS are in better agreement today and there is better confidence in the rather uneventful extended forecast.

Srn CA will be under a cull over the weekend with weak high pressure to the north and south and the upper low to the west.

There should be enough offshore sfc flow and lingering cool air to keep the low clouds away. Temps will rise to near normals on Saturday and change little on Sunday.

Fast moving dry NW flow sets up for Mon and Tue as a CONUS spanning trof settles in over the nation. There may be enough embedded mid or high level clouds to make for partly cloudy skies.

Hgts fall each day and MAX temps will fall several degrees each day.

Both the EC and GFS show light rain developing Wednesday but hard to place much confidence in any day 8 forecast.

AVIATION 20 1032Z.

At 1030Z, a weak marine inversion was based around 4800 feet.

The top of the inversion was 6700 feet with a temperature of 7 degrees Celsius.

Overall, low to moderate confidence in 12Z TAF package. Moist and unstable air mass will bring scattered showers and MVFR toVFR CIGs and VSBYs to all sites through this evening. Confidence in flight category changes as well as shower timing is low. There is a slight chance of TSTMs through this evening along the Central Coast as well as Ventura and Los Angeles counties.

KLAX... Overall, moderate confidence in 12Z TAF. High confidence in development of SHRA and MVFR CIGs and VSBYs through this evening, but low confidence timing of SHRA as well as flight category changes. There is a 15% chance of a TSTM through 00Z. No significant easterly wind component is expected.

KBUR... Overall, moderate confidence in 12Z TAF. High confidence in development of SHRA and MVFR CIGs and VSBYs through this evening, but low confidence in timing of SHRA as well as flight category changes. There is a 15% chance of a TSTM through 00Z.

MARINE 20 232 AM.

For the Outer Waters, high confidence in current forecast. Gale force winds will continue this morning, then will diminish to Small Craft Advisory (SCA) levels this afternoon and evening. For Thursday through Saturday, winds will remain below SCA levels then will increase to SCA levels on Sunday.

For Friday through Saturday, seas will remain below SCA levels, but will likely increase to SCA levels on Sunday.

Thunderstorms will be capable of producing locally rough seas, brief heavy rain, gusty erratic winds and frequent lightning.

BEACHES 20 232 AM.

A cold storm system will move over the region today and Thursday.

As this storm moves through, it will generate high surf conditions along the coast through Thursday morning. For the Central Coast, peak surf heights between 8 and 12 feet are expected while surf height of 4-8 feet are expected south of Point Conception.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
