320 am pdt Tue oct 16 2018
Dry conditions are expected to continue with temperatures
remaining at near normal values through out the week.
Strong winds observed on Sunday Monday diminished with localized
breezy conditions over the mountains of tulare and kern counties
this morning. The associated upper low that generated the strong
winds is currently over arizona and progged to move slowly
northeast toward the four corners area by mid-week. This shift
in the upper level pattern will allow the ridge axis to approach
the west coast as dry and warm conditions will prevail for the
reminder of this week. While the blocking pattern over the west
will transition to a rex block form by this weekend, change is in
store as subtropical moisture is tapped to surge toward the
district during the weekend and into early next week.
While uncertainty still exist on how the pattern will evolve
toward the end of the week, confidence is growing toward a
possible rex block with the center of the low around san diego to|
offshore of the san diego area. This solution may allow for a
northward surge of moisture into the region as the flow becomes
east to southeast. At the moment, will increase the potential of
precipitation and cloud cover for the latter part of the forecast
period (around Sunday - Monday) and wait until better consensus
of models can be reached. Therefore, for now, will keep the
district dry during the next seven days. Otherwise, will expect
temperatures at near normal values while a blocking pattern
dominates the area.
Vfr conditions will prevail over the central california interior
during the next 24 hours.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
