Synopsis
Dry weather thru mid-week. Rain chances along with high mountain
snow and cooler temperatures late in the week followed by a
warming trend this weekend.

Discussion
Varying amounts of high cloudiness moving across norcal with
westerly flow across the region. Temperatures are up a bit
compared to 24 hours ago and winds are generally light.

Dry weather continues the next couple of days with mild days and
cool nights. Periods of high clouds will be possible as the weak
wave moves through today, and more high cloudiness is likely the
next couple of days as moisture spreads northward from the
subtropical low pressure system offshore.

Low pressure system diving southeast from the aleutians is
forecast to deepen a trough along the west coast Thursday into
Friday bringing cooler and breezier conditions. Models continue
to trend drier and further north with QPF with much of it
occurring along the cold front as it moves south Thursday night
and early Friday. Amounts vary from 1 4 to 1 2 inch over the
mountains to a few hundredths of an inch around sacramento to less
than 1 4 inch near redding. Higher mountain elevations may see a
few inches of snow accumulation.

.Extended discussion (Saturday through Tuesday)
the upper trough pushes east and weakens Friday night into
Saturday morning making way for drier and warmer weather over the
weekend. Daytime highs in the valley will warm into the upper 70s
and low 80s by Sunday. For the foothills and mountains, Sunday
highs will rise to the 60s to mid 70s. Dry weather with additional
warming for the beginning of next week. Jbb

Aviation
Vfr conditions with light winds. Valley winds at TAF sites will
be less than 10 kts. Winds over higher terrain will be light with
a diurnal pattern.

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.
