area forecast discussion
national weather service sacramento ca
341 am pst Mon jan 22 2018

Synopsis
Pacific storm moves through bringing mainly light precipitation.

A stronger system impacts the area mid-week into Friday bringing
moderate to heavy rain, mountain snow and gusty wind.

Discussion
The front has continued to work its way slowly southward across
interior norcal overnight. Precip picked up as a weak wave moved
onshore, and some light to moderate snow will continue across the
northern sierra into the morning with additional snowfall
accumulations up to 4 inches leading to chain requirements along
i-80, so a winter weather advisory has been posted.

Further north, profiler data indicates snow levels have risen
above 3k feet across shasta county and traffic cameras show wet
road surfaces along interstate 5 north of redding, so the winter
weather advisory for that area has been cancelled.

Precip along the front is forecast to taper dramatically by
afternoon as upstream ridging moves in. However, moisture will
remain trapped below the subsidence inversion so clouds will be
stubborn, persistent and slow to clear for much of the region.

After a break, a stronger pacific frontal system spreads inland
over far NW ca Tuesday night then across all of interior norcal
Wednesday. Breezy to windy conditions develop ahead of the front
Wednesday. Models currently show more significant QPF with this
storm. Snow levels ATTM initially look to be around 5000 to 6000
feet Wednesday morning, but lower to 2500 to 3500 feet Wednesday
night into Thursday in post-frontal colder ams. Showery weather
persists Thursday.

.Extended discussion (Friday through Monday)
area of high pressure will bring mostly dry conditions Friday for
northern california, although a few lingering showers across the
cascades and extreme northern sacramento valley are possible. The
next low pressure system to make landfall will affect the pacific
northwest and the cascade coastal mountains of the interior, which
will bring another round of precipitation chances for Saturday.

High pressure returns for Sunday before the next weather making
system approaches for early next week, mainly affecting the
northern valley and mountains.

Aviation
Rain continues to move across interior northern california
bringing reductions in ceilings and visibility for
foothill mountain and valley terminals for the sacramento area and
southward. Precipitation will end later this morning and
conditions will improve by afternoon. Another round of ceiling and
visibility reductions are expected tonight.

Sto watches warnings advisories
Winter weather advisory until 10 am pst this morning for west
slope northern sierra nevada-western plumas county lassen park.

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.
