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.

Synopsis
Hot and dry weather this week, peaking this weekend.

Discussion
Clear skies across interior norcal early this morning. Onshore
flow continues into the central valley and the marine layer remain
around 1k feet deep with satellite imagery showing stratus along
the coast extending locally inland in the bay area. Current
temperatures are running several degrees cooler compared to 24
hours ago thru much of the valley while readings elsewhere are
slightly milder.

Effects from yesterday's short-wave will linger this morning, but
anti-cyclonic flow aloft will return this afternoon leading to
slightly warmer temperatures compared to Wednesday as onshore
flow is expected to slacken a bit.

Widespread triple digit heat is expected on Friday as surface flow
becomes northerly and the delta breeze diminishes. Temperatures
will be as hot or perhaps slightly hotter on Saturday. Given the
potential for heat-related illnesses with this sharp but
relatively brief heat stretch, an excessive heat watch has been
issued across the sacramento and northern sj valleys, along with
adjacent foothills.

.Extended discussion (Monday through Thursday)
upper trof moving through the pac NW on Mon will bring some
cooling to norcal as sun's ridge axis is pushed inland by the
trof. Lowering 5h heights and synoptic cooling should lower max
temps some 5-10 degrees most locations. Slight differences in the
modeling beyond Mon into the middle of the week results in some
uncertainty as to the amount of cooling (or lack of cooling) over
norcal as the mod trend tool shows a rather stable forecast 5h
pattern over norcal until Wed when there is just a slight
variation. Although there should be an increase in onshore
gradients by midweek which should provide some cooling to the
delta influenced areas, the warmth should continue elsewhere. Have
adjusted most of the temps upward during the efp wrt to the mex
guidance. However, more significant height falls on Thu should
offer a little more cooling to our cwa. The closed low descending
into norcal next Sat (30th) per the ECMWF looks overdone, but can
certainly buy off on a more progressive trof per the GFS given the
time of year. Jhm

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.
