area forecast discussion
national weather service sacramento ca
307 pm pdt Wed oct 16 2019

Synopsis
A weather system will sweep across northern california bringing a
chance of showers tonight and tomorrow morning. This weekend
another weather system will bring a chance of showers on Friday
night through Saturday. High temperatures are forecast to be just
below average through the weekend before warming to slightly
above average early next week.

Discussion
High clouds have filled in over the region ahead of a cold front
which is expected to move through our area overnight. Radar
indicates a rain band starting to push onshore over the far
northwestern portion of the state as of 2:30 pm. We are expecting
the northern valley to feel some drops by 8:00 to 9:00 pm with shower
chances spreading southward overnight. The sacramento area will
likely be getting some light precip in the pre-dawn early morning
hours. Rain totals are expected to be minimal with better chances
in the mountains. Amounts will vary from less than a tenth of an
inch in the valley to around a quarter to a third of an inch over
the mountains. We could also see a light dusting of snow at
higher elevations. The system is forecast to quickly head east on
Thursday with only a few showers lingering near the northern
sierra crest into the afternoon.

This weekend, models have been consistently indicating another
weather system grazing northern california. However, the location
and timing of this system has been changing slightly with
subsequent model runs. Best chances for precip are likely to be
late Friday and into the day Saturday. This looks to be a fast
moving system as well and will likely yield less than a quarter
for all locations with valley locations possibly only seeing a few
sprinkles.

Extended discussion (Sunday through Wednesday)
Little change to the forecast package this afternoon as models and
ensemble guidance remain in fair agreement. Dry conditions are
forecast for Sunday as the late week upper trough pushes east of
the area. High pressure will be building behind this departing
system, which will lead to increasing temperatures. Daytime highs
are expected to be 5 to 10 degrees above seasonal normals, with
widespread low to mid 80s in the valley. Periods of locally breezy
northerly to easterly winds could be possible late Sunday into
Monday, and again on Wednesday. However, wind speeds don't look as
strong as last week's event.

Aviation
An weak storm system will bring cloudy skies and light rain to
portions of interior northern california.VFR conditions are
expected to prevail, but should heavier showers roll over the taf
sites, bouts of MVFR conditions could be possible.

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.
