Synopsis
Another weather system will impact northern california later today
into Tuesday bringing more rain and mountain snow. Below-average
temperatures continue through the week with additional mountain
shower chances.

Discussion
Clear to partly cloudy skies cover the region early this morning
as short-wave ridging provides a brief lull in the unsettled
weather. Current temperatures are chilly ranging from the mid 20s
to mid 30s in the mountains to the mid 40s to lower 50s across the
central valley.

Next upstream system seen on satellite imagery crossing inside of
140w north of 40n will move southeast today and approach norcal by
later in the afternoon. Increasing instability and surface
convergence may lead to a few showers and thunderstorms across
the far northern portion of the forecast area late in the day into
this evening.

More widespread shower activity will spread across norcal later
tonight and Tuesday as the front surges southward. Showers will
continue Tuesday night in the unstable post-frontal airmass. Most
of the shower activity on Wednesday and Thursday is expected over
the northern sierra nevada, but northeasterly flow may allow some
showers to drift down into the foothills and eastern edge of the
central valley.

Another shot of snow is expected for the northern sierra late
tonight through Tuesday, and a winter weather advisory has been
posted.

Temperatures will remain well below average early this week, but
are expected to moderate somewhat by mid-week.

.Extended discussion (Friday through Monday)
unsettled weather looks to continue through much of the extended
forecast periods as a series of low pressure systems move through
interior norcal. Best chances for showers looks to be over the
foothills and mountains. Below normal temperatures expected Friday
into Monday with high temps upwards of 5 to 10 degrees below
normal next weekend.

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.
