Synopsis
A slow moving storm system arrives today. A stronger storm is
possible Tuesday night and Wednesday with afternoon thunderstorms
possible on Wednesday. Unsettled weather will continue on
Thursday with scattered showers before the return to dry weather
for Friday into the weekend.

Discussion
Water vapor imagery this afternoon showed a conglomerate of upper
lows spinning off the coast. An embedded perturbation within the
southwesterly flow has spawned a band of light showers generally
along i-80 northward. Meager hourly amounts in the 0.05 to 0.10
inch range have been observed at this point. This warm advection
precipitation should continue through the evening and night but
totals should not equate to a whole lot over valley locations.

Accumulating snows over the southern cascades enforces the need
for a winter storm warning until late tomorrow morning while a
winter weather advisory will remain over the northern sierra.

The strongest upper low within the offshore axis of lower heights
will make its way toward the northern california coast on Tuesday
evening. Before then, expect widely scattered showers to fill the
region with the better precipitation threat holding off until
Tuesday night into Wednesday.

A winter storm warning will be in effect throughout the duration
of this mentioned storm given moderate to heavy snowfall
accumulations. For elevations above 5,000 feet, expecting around 2
to 3 feet of snow through Thursday with higher amounts possible
over the mountain summits. Travel across these regions will be
hazardous and is not advised. Snow levels should meander between
5,000-5,500 feet before falling to around 4,000 feet by early
Thursday. At this point, conditions will be turn more showery in
nature given cyclonic flow overhead.

Across valley locations, an extended period of light to moderate
rainfall will raise forecast totals to around 1 to 1.50 inches
with lower amounts across the upper san joaquin valley. Local
upslope effects will augment amounts in the foothills with 2 to 3
inches possible. Besides the rainfall threat, modest instability
within breaks in the clouds may lead to some scattered
thunderstorms on Wednesday. These would be capable of heavy
downpours, lightning, and small hail. Otherwise, conditions may be
breezy at times within the broad southerly flow regime.

Conditions will gradually improve toward the conclusion of the
work week with scattered showers remaining Thursday. Temperatures
will sit below average with the highest numbers (mid upper 60s)
down toward stockton and modesto through Tuesday. ~bro
.Extended discussion (Friday through Monday)
lingering showers possible Friday, mainly over the mountains of
shasta and western plumas counties. Drier weather expected
Saturday as upper level ridging moves through interior norcal. By
Sunday, gfs, gefs, naefs, suggest probability for some light
precip on the increase as short wave trough approaches.

Precipitation looks to be more widespread Monday over norcal with
additional waves, however overall precip continue to look light
attm.

Aviation
Rain will continue to spread over northern california, which will
bring periods of MVFR conditions and increased southerly wind
gusts to 22 knots.

Sto watches warnings advisories
Winter storm warning until 11 am pdt Tuesday for west slope
northern sierra nevada-western plumas county lassen park.

Winter weather advisory from 7 pm this evening to 11 am pdt
Tuesday for west slope northern sierra nevada.

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.
