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
Clear nite for viewing the leonid meteor showers this evening. In
the wake of the upper trof moving into the great basin and into the
rockys by morning, high pressure will build in behind it and into
norcal. Nly winds should be subsiding by morning in the valley and a
strong radiative inversion will form. Moisture trapped below the
radiative inversion from the recent rains could lead to some
radiation fog early Sat morning. After 12z sat, the hrrr surface
winds are progged to shift to light sely which is a more favorable
direction for some fog. It does not have the ingredients for a
widespread f+ event as dewpoints rhs have succumbed to the nly winds
and we expect mainly MVFR vsbys in the morning. Near the river
valley there may be some mifg (ground fog) causing some brief lower
ifr vsbys. Jhm

Previous 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)
forecast confidence remains low through the extended period. The
latest runs of the GFS and ECMWF build a very strong ridge into
the desert southwest, which would force the storm track farther
north than previously projected (mainly toward the pacific
northwest). It still appears that periods of light to moderate
precipitation will be possible, and could possibly impact
thanksgiving holiday travel. Our forecast favors a blend of the
gfs and ECMWF models.

Aviation
MainlyVFR conditions with light north winds the next 24 hours.

Patchy fog may develop from ksmf southward Saturday morning.

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.
