400 am 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
Upper troughing digging over interior norcal is helping to deepen
584 dm upper low off the socal coast. Low forecast to be
quasistationary through Tuesday before progged to open to trough
and move inland Wednesday. Synoptic cooling and onshore flow will
result in a cooling trend over the next several days with highs by
Tuesday in the upper 80s to 90s in the central valley, with 60s to
80s for the mountains and foothills. Northerly wind over northern
portions of the CWA today will make for some hazy skies as it
draws smoke southward from numerous oregon wild fires. Instability
and moisture convergence over the higher elevations of the sierra
nevada and mountains of western plumas will result in afternoon
thunderstorms again.

Upper low off the socal coast will continue to draw moisture
northward into the area over the next several days leading to a
more widespread threat of deep moist convection, mainly over the
mountains and in the afternoon to evening hours. Tuesday into
Tuesday night looks to be the most active period for mountain
storms. Slight chance of showers and thunderstorms continues over
the higher terrain Wednesday, as temperatures edge up a few
degrees.

Btw, skies should be mostly clear for Monday's eclipse viewing,
however haze smoke may come into play for northern portions of
the cwa.

Pch
.Extended discussion (Thursday through Sunday)
medium range models showing broad troughing aloft continuing over
the forecast area Thursday into Friday then height rising over the
weekend. Drier weather expected with a gradual warming trend.

Temperatures forecast to be around 2 to 6 degrees above normal by
the end of the forecast 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.
