area forecast discussion
national weather service sacramento ca
152 pm pdt Sun aug 20 2017

Synopsis
Temperatures near to slightly above normal through the upcoming
week. Afternoon showers and thunderstorms possible over the
mountains through Wednesday.

Discussion
First up for eclipse viewers in norcal... Skies still look to be
mostly clear Monday morning. However, some smoke haze could linger
across far northern portions of the state due to numerous
wildfires still burning across oregon and NW california.

In other news... Upper level troughing will remain over norcal
into mid-week as upper level low deepens off the socal coast. Low
will meander near the coast through Tuesday before opening up into
a trough and moving onshore Wednesday. This will continue to draw
moisture north into the area, with daily chances for afternoon
showers and thunderstorms across the mountains, possibly even the
coastal range by Monday. Thunderstorms look to be most numerous on
Tuesday with more widespread activity across higher terrain. Any
storm will be capable of producing small hail and locally heavy
downpours. A few could be strong.

Onshore flow will lead to cooling over the next several days with
highs back down to within a few degrees or normal by Tuesday and
Wednesday. Decent marine layer should keep flow going through the
delta with breezy winds in that vicinity and additional cooling.

Ceo
.Extended discussion (Thursday through Sunday)
quiet weather with warming temperatures is expected for the
extended period. A trough will be pushing to the east on Thursday
and then we will see a ridge build in for Friday and the weekend.

This will help to push highs back above average by 4-8 degrees for
the weekend. No precip is expected throughout the period.

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.
