Synopsis 23 1224 pm.

Mostly clear skies will prevail this afternoon and temperatures
will be warmer than earlier this week but remain below normal.

The dry weather will persist into early next week and
temperatures will warm up to near normal. There is a chance of
light rain by midweek over northern areas.

Short term (tdy-tue) 23 153 pm.

Mostly sunny skies with a few high clouds covered the forecast area
early this afternoon. Increasing amounts of high clouds are expected
thru the rest of the day, but overall the mostly sunny skies should
prevail thru sunset. Generally weak onshore breezes can be expected
across much of the area this afternoon as well. Temperatures will
top out in the upper 50s to lower 60s for the coast and valleys,
which are still several degrees below normal.

Weak, flat upper level ridging is expected to move over SRN ca this
afternoon. A mainly zonal flow aloft with little change in 500 mb
heights should prevail tonight through mon. 500 mb heights should
remain in the 566 to 568 dm range thru the period. An upper level
trough over the E pac will approach the area Mon night and tue,
with the upper level flow turning more SW by early tue.

Generally benign weather is expected over southwestern ca tonight
thru mon. Fair skies will prevail for the most part thru the period
with varying amounts of mainly hi clouds expected to drift overhead
at times. There is also the possibility that patchy marine layer
clouds may develop along the central coast and l.A. County coast
later Sun night into Mon morning. Some breezy offshore flow is
expected for the wind-prone areas tonight into Sun morning, but
overall winds will be weak and variable across the region thru
mon.

A pacific front is expected to extend from the bay area and SW over
the E pac Mon night, with this front slowly sagging S toward slo
county thru tue. Moisture from this front is forecast to push into
northern slo county late Mon night and Tue with a chance of rain
increasing over that area. Otherwise, mainly mid and hi level
clouds should increase across the entire forecast area during the
period. It looks like Tue should be a partly to mostly cloudy day
overall across the region, with south to southwest breezes out
ahead of the approaching front, especially Tue afternoon.

Temperatures are forecast to be slightly warmer Sun thru Tue thanks
in part to gradually increasing 1000-500 mb thicknesses. Highs in
the warmest vlys and coastal areas are expected to be in the 60s
each day which are still a few degrees below normal.

Long term (wed-sat) 23 156 pm.

The GFS and ec are in generally good agreement for the extended
period. A weak upper level trof will slide to the N of the
forecast area late Tue night and wed. This will help to bring
additional moisture into the region from that pacific front as it
moves into the central coast while weakening thru wed. Rain may
become likely for portions of slo county on wed, otherwise a
chance of rain will prevail for sba vtu counties with a slight
chance of rain for western l.A. County. There will be residual
moisture over the area as the front dissipates Wed night into thu,
with a gradual decrease in the chance of showers thru thu.

Potential rainfall amounts from this system Wed thru Thu are for
0.25 to 0.50 inch over slo county, with local amounts possibly up to
an inch or more in the NW slo county hills, 0.15 to 0.30 inch for
sba county, and 0.10 inch or less elsewhere. Snow levels will be
quite high so no snow issues are expected.

Some upper level ridging should move into the area Thu night and
fri. Plenty of mainly mid and hi level clouds should move back into
the area on fri. Otherwise, dry and mild conditions are expected
over the forecast area, except for a slight chance of rain over
slo sba counties by Fri afternoon as a pacific weather system
approaches.

The upper level ridge will weaken Fri night, with weak upper level
troffiness expected to move in sat. A pacific front will move into
the forecast area with a good chance of rain Fri night and sat,
especially for slo sba counties. Snow level will likely be high with
this system, with any snow accumulations above 8000 feet.

Temps will be near normal to a few degrees below normal for the most
part thru the period, with Fri the mildest day. Highs in the warmest
vlys and coastal areas should be generally in the 60s each day,
except mid 60s to around 70 on fri.

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.
