339 pm pdt Wed jun 28 2017

Synopsis
Warmer with daytime highs 5 to 10 degrees above average through
Saturday followed by slight cooling to more seasonal temperatures
early next week.

Discussion
Ridging over the eastern pacific builds into norcal through this
week bringing a warming trend to our daytime highs. The fort ord
profiler along the coast shows a decreasing marine layer which
will weaken onshore flow and aid in the warmer temperatures by
suppressing the delta breeze the next few days. Daytime highs will
range about 5 to 10 degrees above normal through Saturday. Valley
highs will see upper 90s to low 100s with higher terrain in the
80s and 90s.

Delta breeze will start to return Friday morning, but will
strengthen a bit Saturday morning as a short-wave moves across
norcal. This could bring in some patchy low clouds during the
morning hours on Saturday. It should also allow for a degree or
two of cooling, compared to Friday, especially for delta breeze
influenced areas (sacramento metro region to stockton). It's
doubtful any convection will occur from this short-wave given the
dry airmass. Jbb
.Extended discussion (Sunday through Wednesday)
dry conditions will prevail across interior norcal through the
extended period. Broad upper trough deepens over the pacific
northwest early next week, resulting in minor cooling as the ridge
flattens. However, highs will remain slightly above normal on
Sunday, with seasonal temperatures returning Monday-Wednesday.

Looking ahead, high pressure ridging expands northward across the
region by the middle of next week.

Aviation
Vfr conditions the next 24 hours. Winds will remain south to west
today, generally below 10 kt across valley TAF sites. Near the
delta... Sw wind gusts up to 30 kt 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.
