What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

A weak disturbance over the coastal waters will result in gusty northerly winds over the northern outer waters and lighter variable to southeasterly winds elsewhere. Northwesterly winds will redevelop over the coastal waters early next week. Gusty onshore winds will redevelop north of the bay bridge to the delta later today and again later Saturday. A long period southwesterly swell arrives by early next week.

Synopsis
Temperatures will gradually decrease the remainder of the week
with the potential for thunderstorms in the mountains. Hot
weather returns next week.

Discussion
Clear skies across interior norcal early this morning. Current
temperatures range from the upper 40s to mid 50s in the mountain
valleys to the mid 60s to mid 70s across the central valley
(except lower to mid 80s across the north end of the sacramento
valley).

Strong upper ridging of the past several days will weaken a bit
through the end of the week as an upper low traverses southern
bc with a weak trough trailing back into norcal. The combination
of a little stronger onshore flow along with slight synoptic
cooling will result in a little cooler temperatures across the
region over the next few days.

Additionally, an increase in monsoon moisture will bring greater
cloud cover helping to edge temperatures down a bit as well. With
the return of monsoon moisture spreading further north,
thunderstorm activity will become more widespread across interior
norcal through the weekend. Most of the action is expected to be
diurnal in nature and mainly over the mountains, but we can't
completely rule out a slim chance for a few storms occurring
elsewhere tonight and early Saturday as moisture spreads north.

The ridge is forecast to reassert itself early next week resulting
in a return to hot weather and capping the extent of mountain
thunderstorm activity.

.Extended discussion (Tuesday through Friday)
an expansive upper level ridge will bring hot weather across the
region next week. By even july standards, this upper ridge will
likely be rather anomalous, with naefs (north american ensemble
forecast system) guidance projecting 500mb heights to be 3-4
standard deviations higher than normal over az nm. We will be on
the northern fringe of this upper ridge, but with high confidence
in the pattern we nudged temperatures up a few degrees across much
of the extended period. Current consensus of solutions has
widespread triple digit heat across much of the central valley
through the extended period, with temperatures potentially
approaching 110 degrees again across the northern valley. Dang

Aviation
Vfr conditions the next 24 hours across TAF sites. South to west
winds 5 to 15 knots, except gusts to 30 kt near the delta. Dang

Sto watches warnings advisories None.

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.
