Synopsis
Weak system brings a slight chance of light showers over the
northern mountains this afternoon into tonight, otherwise dry
through early next week. Breezy to windy conditions forecast this
weekend, resulting in increased fire potential.

Discussion (today through Monday)
Upper ridging along the west coast being squashed as short wave
trough progresses. Clouds are increasing over interior norcal,
with ceilings lowering, as cold front approaches. System moves
through tonight however dynamics are weak and available moisture
is limited. Models continue to show a few light showers possible
over the shasta and plumas mountains, and possibly higher
elevations of the northern sierra nevada. QPF is less than a
tenth of an inch with little to no snow accumulation expected.

Surface and upper ridging builds back inland behind this wave
late tonight into early Saturday. Strong pressure gradients
develop overnight, leading to breezy to windy conditions across
interior norcal Saturday. Latest model guidance is suggesting
wind speeds into advisory criteria Saturday across portions of the
central valley, especially over the western half extending into
the coastal range. Gusty wind will lower humidities, and with dry
fuels already in place, there will be increased fire potential.

Red flag warning and wind advisories are in effect. Synoptic
cooling on Saturday will result in highs in the upper 50s to lower
60s for the central valley with 30s to 50s for the mountains and
foothills.

Breezy conditions continue Sunday, but wind speeds and pressure
gradients look to be less. Winds will generally be light Monday as
heights and temperatures slowly trend up.

Pch
.Extended discussion (Tuesday through Friday)
confindence is improving that a cold upper trough from the gulf
of alaska will drop down through the region on Wednesday, bring
the potential for precipitation to most of the area. This trough
has trended a little deeper and wetter, though this is not
expected to be a very wet system. Up to around a third of an inch
of liquid equivalent is expected in the mountains, up to around a
tenth of an inch in the valley. Snow levels will drop quickly
behind a strong cold front Wednesday afternoon, down to around
3500 feet over the southern cascades, 5000 feet in the sierra.

Snow amounts of 1 to 3 inches are currently projected by Wednesday
evening. Drier weather returns by Thursday and continues into the
weekend.

Temperatures cool from Wednesday on, with valley and foothill
highs generally remaining in the 50s, morning lows in the 30s. Ek

Aviation
Vfr conditions across interior norcal over the next 24 hours
except local MVFR in br for the southern sacramento and northern
san joaquin valleys. Valley northerly winds generally below 10
knots this evening, increasing to 22 kt by around 18z, with gusts
to 40 kt. An airport weather warning is in effect for sck, with
sustained winds 20 to 30 kt in the afternoon. The northerly winds
will inhibit fog formation, but morning br is possible. Ek

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.
