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
Weak system will continue moving through the region keeping
temperatures below normal and bringing breezy to gusty afternoon
and evening winds to the kern county mountain desert areas and
coastal pass locations. High pressure will begin moving into the
region later this week and will bring a return to above normal
temperatures and continued dry conditions.

Discussion
Yesterday temperatures were kept well below normal thanks to a
trough moving through the region and some mid-level marine induced
clouds helping to keep solar insolation to a minimum yesterday
across the sjv. Normal highs are in the lower 90s and yesterday we
only managed to get to a high of 78 at both fat and bfl. Today
cloud cover will be greatly reduced and will allow temperatures to
get closer to the normal levels. Breezy to gusty winds will be
possible for the kern county mountain desert areas and the coastal
pass areas on the western side of the sjv due to weak marine
intrusions.

As we get to the middle of the week, high pressure will begin
moving into the region late Tuesday and by Wednesday temperatures
will once again approach the century mark. This ridging will
dominate the area well into the weekend and at this time Saturday
looks to be the hottest day. There is a bit of uncertainty later
in the weekend with a few weak shortwaves progged to move through
northern california. However with this broad ridging my
inclination is to lean more to the ridge winning out and keeping
temperatures hotter. However, if clouds are increased due to the
shortwave passages, then all bets are off and temperatures could
easily be cooler by 5-8 degrees. This would be the only fly in the
ointment so to speak with the forecast, otherwise every thing else
looks to be on track. It will be interesting to see what happens
next week as there is an active pattern well to the north of us
and any of those systems could meander southward and give us a
cool down. This has been the pattern lately and would not be
surprised to see this happen. Heck, who would of thunk we would
have upper 70s in the second week of june around here? Believe me
i am not looking a gift horse in the mouth, and will definitely
take as much of this as I can get. Remember, with the return to
hot temperatures later this week to keep in mind cold water
safety, with hot air temperatures and still fairly cold river
waters, shock can easily set in and increase chances of drowning.

So be sure to wear a life vest if seeking refreshment in local
waterways.

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.
