Synopsis High pressure will bring another dry and warming day
today before a fast moving and potentially windy storm system
drops into the great basin on Thursday and Thursday night. High
pressure will return for more springlike conditions for the
Discussion A few high clouds are drifting overhead as they
spill over a pacific ridge extending along the west coast. This
ridge will provide generally mild conditions today with
temperatures pushing a few to several degrees above climo.
These tranquil conditions will be briefly interrupted as the next
frontal system drops through the pacific northwest and into the
great basin Thursday.
Models handle this system similarly and this inside slider type
trajectory will be a mostly dry event for our area. Precipitation
chances will be mainly confined to the mountains as the system
passes Thursday, though can't rule out a few light showers in the
lower elevations north of kern county. Snowfall will mainly occur
above 6-7 thousand feet with no more than a few inches expected at
the highest elevations. The main effect of this frontal trough
will be strong gusty winds. Gusty west to northwest winds will
develop by late morning Thursday as the system moves through the
region. Winds will likely gust around 30 mph during the afternoon|
Thursday, with some locally higher gusts, especially through
westside passes. 50 to 55 mph are likely across the kern county
mountains and desert areas, locally higher in the typically windy
spots. A wind advisory remains in effect here Thursday afternoon
Model agreement continues into the weekend as the low pressure
system moves into the southwest us and high pressure rebuilds
across our area. This will bring dry and calmer conditions with
temperatures trending back above climo. Model solutions then begin
to drift apart a bit for the first part of next week but generally
agree on weakening the ridge as a trough moves into the region
around Monday. Precipitation chances with this passing trough are
minimal and it is expected to mainly bring another round of gusty
winds and cooler temperatures for the early part of next week.
Vfr conditions are expected across the central ca interior for the
next 24 hours.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
