Synopsis
Several weather systems move through bringing cooler temperatures
with some light precipitation through Wednesday.

Discussion
Light rain has made it about as far south as i-80 early this
morning as deeper moisture extending across the eastern pacific
interacts with a weather system pushing into far northern
california. Observed rainfall amounts overnight have ranged from
a few hundredths of an inch in the sacramento valley to around a
quarter to half an inch in the foothills and mountains east of
redding and red bluff. Current temperatures are in the 30s and
lower 40s in the mountains with mid 40s to mid 50s elsewhere.

Moisture will continue to stream into the area over the next 24
hours continuing a threat for light precipitation as the front
lingers across norcal. The sacramento area may see a few
hundredths of an inch of rain early this morning, but most of the
qpf will remain to the east of the valley over the foothills and
northern sierra. Scattered showers may redevelop this afternoon.

Snow levels are around 5500-6500 feet early this morning and are
not expected to change much into early Tuesday. Around 2-4 inches
of snowfall accumulation will be possible along the crest of the
northern sierra with perhaps 6 inches up around the mt lassen
area.

Another weather system is forecast to skirt the region later
Tuesday into Wednesday. Most of the precipitation will be over
the mountains north of i-80 but a few showers may affect the north
end of the sacramento valley. Snow levels will be high and
accumulating snow is only expected over the tips of the highest
peaks.

Breezy north winds along with warming and drying conditions
commence Thursday.

.Extended discussion (Friday through Monday)
high amplitude upper ridging in the epac builds inland over
interior norcal Friday into the weekend bringing dry weather with
warming temperatures. Gusty northerly wind expected Friday into
Saturday which may require wind advisories. Above normal
temperatures forecast over the weekend with highs climbing into
the lower 80s in the central valley Sunday and Monday.

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.
