Synopsis
Dry weather through Sunday. Next system moves through Monday with
another during mid week. Each of these next systems will come
with light to moderate precipitation and high snow levels
generally above pass levels.

Discussion
Major weather system of the past few days has moved into the
great basin region. Pacific ridge is building over norcal behind
this system with dry conditions and northerly surface winds.

Overnight and early morning fog chances seem less likely as north
wind of 5-10 mph should keep mixing and drying from sacramento
northward. Some patchy fog could form sacramento southward,
especially in river valleys.

Ridging with dry conditions will continue into Sunday with near
normal temperatures in the low 60's. A weak weather system will
bring light showers Monday, best chances northern sacramento
valley and shasta county. Precip should be light with this system,
generally less than 0.25 for valleys and less than an inch
mountains. Snow levels will be high generally above 8000 feet.

.Extended discussion (Tuesday through Friday)
upper level ridge moves eastward as another disturbance slides
into northern california with more chances for precipitation.

Model forecasts are in general agreement to the atmospheric flow
pattern with moisture streaming into the coast in an atmospheric
river type pattern, but right now latest model runs have the brunt
of the precipitation remaining well to the north of california. If
this pattern holds true, light to moderate rain across the
forecast area can be expected with snow levels well above pass
level and light accumulations at high peaks.

Aviation
Vfr MVFR conditions with occasional ifr conditions in the valley
with fog and low stratus development towards the morning hours.

Fog and low clouds will diminish in the late morning to early
afternoon hours to mostly clear skies andVFR conditions for the
taf sites.

Sto watches warnings advisories
None.

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.
