Synopsis
Dry and mild weather today. Rain chances along with high mountain
snow and cooler temperatures Thursday and Friday followed by a
warming trend this weekend into early next week.

Discussion
High cloudiness has shifted further south overnight as west-
southwest flow increases ahead of the approaching late-week
trough. Winds remain generally light and temperatures are running
a bit cooler compared to 24 hours ago across most of the area.

Dry weather with mild temperatures will continue across the region
today. Highs this afternoon are expected to be very similar to
Tuesday's with lots of lower to mid 80s throughout the central
valley and surrounding foothills.

Unsettled weather still ontrack to return to the region Thursday
and Friday with precipitation, much cooler temperatures and gusty
southerly winds. The wetter mountain areas may see as much as an
inch of liquid precip while the valley will generally see less
than a quarter inch and most locales probably just a few
hundredths. Colder air behind the frontal band is expected to
lower snow levels below the major passes on i-80 us-50 where an
inch or two of snow could accumulate.

Gusty ridge winds can be expected later Thursday as the upper
trof moves inland with a southerly 6-7 mbs rdd-sac gradient
forecast (not as strong as yesterday) leading to gusts around 30
mph or so. Also, chance of a stratus intrusion into the sac vly
thu morning ahead of the deepening trof, unless the trof mixes it
out beforehand.

Warm frontal clouds could return Fri nite with WAA precip mainly
staying to our N as strong ridging begins to build for the
weekend.

.Extended discussion (Sunday through Wednesday)
upper ridging over norcal on Sunday will bring dry and warm
weather to the region into midweek. Valley & delta highs on Sunday
will be in the upper 70s to low 80s warming into the mid to upper
80s for Monday and Tuesday. Foothill and mountain regions will be
60s to 70s on Sunday with foothills warming into the low 80s for
the start of the work week. A few degrees of cooling possible on
Wednesday when a weak trough could approach norcal.

Aviation
GeneralVFR conditions with light winds. Local hz fu MVFR
visibility is possible in the delta this morning. 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.
