335 am pdt Thu aug 17 2017

Synopsis
Temperatures near to slightly above normal with a threat of
late-day mountain thunderstorms.

Discussion (today through Saturday)
Strong delta breeze early this morning with marine layer about
2000 ft deep per ft. Ord profiler. Fog product imagery showing
coastal stratus extending inland to near cordelia attm. Patchy
stratus may pop up around the sacramento area around sunrise but
will be short lived. Some warming expected today over interior
norcal as high pressure in the epac builds inland. MAX temps this
afternoon forecast to be around 3 to 7 degrees above normal.

Elevated instability progs point to the potential for deep moist
convection over the higher terrain of the sierra nevada, mainly
south of highway 50, this afternoon.

Slight warming continues over interior norcal Friday under
increased subsidence, shallower marine layer, and weaker delta
breeze. Higher levels of 700-500 mb mu CAPE and tt values
exceeding 30 progged over the higher terrain of the sierra nevada
again tomorrow, but also over the coastal range for a threat of
afternoon to early evening thunderstorms there as well.

Heights thicknesses trend down over interior norcal through the
weekend as upper troughing deepens over the area. As a result,
onshore flow increases along with depth of marine layer. High
temperatures trend down to near normal by Sunday. Afternoon
thunderstorms again possible over the higher terrain of the sierra
nevada Saturday, expanding to increase the NE and N mountains
Sunday.

Pch
.Extended discussion (Monday through Thursday)
an upper level low will be setting up off the coast of socal to
start the extended period. This will push moisture north into
norcal and bring a chance for mountain t-storms during the
afternoon and evening both Sunday and Monday. Of course Monday is
a day you will want minimal cloud cover to see the eclipse. It
dose look like there will be enough moisture to see some clouds in
the valley but not expecting widespread cloud cover. Not as much
moisture is expected on Tuesday and that should limit the
thunderstorm chances but still could see some activity mainly over
the coastal range of tehama and shasta counties. On Wednesday the
upper level low pushes east as a trough drops south out of the
gulf of alaska. This will bring troughing for the end of the
period but mountain thunderstorm chances look limited. Overall
temperatures will be seasonal throughout the period to maybe a few
degrees below normal on Tuesday.

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.
