Synopsis
Dry and milder weather expected for norcal through most of
Wednesday. Another system will brush the region late Wednesday
through Thursday with a few showers. Dry and warmer weather
returns for the weekend.

Discussion
Temperatures are running 5 to 8 degrees warmer this evening than
last night. A few high clouds are spilling over the ridge and
into the area. Some north winds continue this evening but are
lighter than earlier in the day. A light northerly wind will
continue most of the night. Temperatures will end up being a
little warmer overnight bottoming out in the upper 40s to lower
50s for the valley. Lows for the mountain valleys will still be
cold bottoming out in the 20s and 30s. Wednesday looks to be
another dry day for most locations. The only exception might be
late in the day when there will be a chance of showers over the
north end of the valley and surrounding mountains.

Previous discussion
High pressure continues to influence northern california weather
today with slightly above normal temperatures. The approaching
surface high and the meso low in the valley has created a surface
pressure gradient with breezy north winds that will continue
through the early evening hours.

Warm and dry weather will last through tomorrow before an
approaching shortwave trough of low pressure will bring increasing
clouds and a return of some light rain for the valley and snow for
elevations higher than 4000 feet. Little impacts are expected from
the precipitation with light snow and rain accumulations expected.

Once the quick moving system exits the region Friday morning and
precipitation tapers off, a stronger upper level jet will move
into the region behind the passing trough which may translate to
gusty conditions Friday.

.Extended discussion (Saturday through Tuesday)
Saturday will be the warmest day in the extended forecast. High
pressure ridging over norcal will allow daytime highs in our cwa
to range 10-15 degrees above normal. That translates to valley
highs in the upper 70s to low 80s with 60s to 70s across higher
terrain. Sunday temperatures will still be above normal
by about 10 degrees as ridging weakens. A subtle trough passes
north of ca on Sunday into Monday, but this system in not
expected to bring much, if any, precipitation to our region. Some
light showers may skirt the sierra Sunday night into Monday. By
Monday, slight cooling continues with highs only being about 5
degrees above normal with dry weather as ridging redevelops along
the west coast.

Aviation
Vfr conditions continue for interior northern ca the next 24
hours. Expect valley TAF sites to range 5-10 kts with north to
northwest flow overnight into Wednesday morning.

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.
