255 am pdt Thu jun 29 2017

Synopsis
Slightly warmer temperatures today with warm conditions through
the weekend. Slightly cooler next week but remaining a little
warmer than normal. No mountain thunderstorms expected through the
extended period.

Discussion
Fair skies over the CWA this morning under high amplitude upper
level ridge over the eastern pacific. Still have a fairly healthy
delta breeze blowing this morning with a moderate marine layer
hanging in at around 1600 feet. Some coastal stratus moving into
the bay area and may see some patchy stratus this morning western
solano county. Airmass warms a bit today as upper ridge axis
centers over the area so expecting high temperatures today a few
degrees over yesterday. Subsidence and stability over the region
under the ridge will keep any mountain thunderstorm threat
out of the forecast over the next several days. Upper ridge axis
crosses over the north state Friday bringing more warming with
daytime highs expected to reach up to about 10 degrees above
normal. A moderate delta breeze is expected to continue but high
pressure ridging will keep the marine layer and stratus intrusion
into the delta minimal. A weak upper trough passing through the
pacific northwest on Saturday will have minimal impact on cwa
weather with its main impact to keep daytime highs Saturday from
climbing. Upper ridging moves quickly back over the west coast
bringing a slight warming again on Sunday.

.Extended discussion (Monday through Thursday)
high pressure aloft will create warm and dry conditions across
northern california with temperatures near normal. A trough
pattern could develop for the middle of next week, but model
forecasts are still a bit uncertain and lack agreement. If a
trough does develop, temperatures could drop a few degrees but
will still remain near normal. Best lift dynamics appear to remain
well north of the forecast area, so any development for
precipitation looks very limited at the moment. However, a
mountain shower or thunderstorm cannot be ruled out Wednesday or
Thursday 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.
