Synopsis
Cold overnight lows tonight with brisk northerly winds decreasing
later tonight and Friday. Next chance of precipitation will return
this weekend and continue into next week.

Discussion
Nly pressure gradients have increased to over 10 mbs and gusty
northerly winds will continue until dark when the radiative
inversion will allow form some decoupling of the wind in the
valley. This will allow for strong radiational cooling in wind
sheltered areas and a cold nite. Dry air spreading over norcal
will create wide temp dewpoint spreads limiting the areal coverage
of frost. Looks as if the E side of the sac vly NRN san joaquin
vly would be the most likely area to see some frost, as well as
the cold mountain valleys basins. Cyclonic flow around deep upper
low vcnty of klas will keep clouds banked up near the sierra crest
with some spillover W of the crest. The cyclonic flow will weaken
and become more nwly as the low center moves into the 4-corners
on fri. This will end the lingering showers over the sierra.

Fri looks like a dry day before the next chance of precip is
forecast to move into the CWA late Sat and into sun, mainly over the
nrn mtns and sierra, as low pressure drops swd from b.C. Into wa.

The SRN half of the vly is expected to be mostly dry. But a wet
pattern re-emerges for the start of next week as moisture over the
pacific becomes entrained into the wswly flow to the south of two
upper low centers along and north of 40n. The WRN most center is the
rex portion of the omega-rex block along 150w, and the ERN most
center is the pac NW system. The west coast ivt plume chart
indicates a relatively weak ar will affect areas along 40n from
the last half of 2 24 to near the end of the month, driven onshore
by the two systems. Jhm
.Extended discussion (Monday through Thursday)
active weather pattern looks likely for the extended portion of
the forecast with Monday and Tuesday looking to be the wettest
days; best chances are expected along and north of i-80. Periods
of moderate to heavy rain will be possible for the start of the
work week, as a low pressure system will tap into tropical
moisture. Early QPF amounts suggest about 3-4" in the northern
sacramento valley, tapering to less than 1" in the northern san
joaquin valley; 2-5", locally higher, will be possible over higher
terrain. Snow levels are progged to rise to 4500-5500 feet for
this ar event. Come Wednesday, the precip is forecast to move to
the north; however, models deviate on how fast it will exit the
region.

Aviation
Showers will be possible for TAF sites south of ksmf which may
lead to periods of mvrf conditions. However, once the showers come
to an end later this morning,VFR conditions will prevail.

Brisk N nwly winds 20g30kt developing in the vly after 18z
resulting in light to moderate turbulence during takeoff landing
operations at TAF sites.

Sto watches warnings advisories
Wind advisory until 6 pm pst this evening for carquinez strait
and delta-central sacramento valley-clear lake southern lake
county-northern sacramento valley-southern sacramento valley.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
