245 am pdt Sat mar 25 2017

Synopsis
Lingering mountain showers today then another storm moves
through Sunday into Monday. Drier Tuesday followed by a threat
of another storm midweek.

Discussion
Upper trough axis shifts into the great basin this morning
with lingering showers possible over the mountains. Some patchy
morning valley fog may develop. Otherwise, dry weather forecast
today into tonight as upper level ridge moves through. Next
pacific storm begins to bring a threat of precip into the northern
shasta mountains after midnight then across northern and western
portions of the forecast area on Sunday. Bulk of precip modeled to
move across the CWA Sunday night with showers Monday, mainly over
the mountains. Storm total QPF amounts look to be around half an
inch or less in the central valley, except up to an inch possible
in portions of the northern sacramento valley. Liquid equivalents
in the foothills and mountains look to be upwards of 1 to 2
inches. Snow levels forecast to be around 4000 to 5500 feet
during the peak precip period and snow totals point to advisory
amounts at this time. Some breezy conditions possible Sunday
afternoon into evening but wind speeds remain below advisory
criteria.

Increasing subsidence over the area Monday night into Tuesday as
upper level ridging in epac pushes inland. Surface high also
builds inland across oregon into the great basin. This will
increase the low level n-s pressure gradient over interior norcal.

Tightened surface gradient along with momentum transfer from
stronger winds aloft will result in some breezy northerly wind
over the CWA Monday night and Tuesday. Above normal temperatures
expected Tuesday with highs in the lower 70s for the central
valley with 50s to 60s for the mountains and foothills.

Pch
.Extended discussion (Wednesday through Saturday)
generally dry weather late next week as high pressure builds over
norcal, except for a slider system forecast to drop southeast
from the pacific northwest on Thursday. Showers with this system
will be limited to mainly the northern mountains and northern
sierra nevada. Otherwise, breezy northerly winds expected at times
along with milder temperatures.

Aviation
Areas of MVFR/ifr along with isolated showers linger through
about 20z as weather system exits the area, otherwise generalVFR
conditions expected as high pressure builds over the area. Winds
generally under 10 kts at TAF sites. Next system moves into the
region mainly after 18z Sunday.

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.
