Synopsis Dry weather can be expected over the central
california interior for the next several days. Temperatures
will cool to near normal by Sunday and Monday. Hot weather
will return during the mid to later part of next week with
highs above 100 degrees in the san joaquin valley, lower
foothills and the kern county desert.
Discussion The stage is set for a significant cooling trend
over the central california interior during the next few days.
As of this writing, temperatures are already trending 3 to as
much as 15 degrees lower than 24 hours ago over the northern half
of the state. Brisk winds are blowing through the sacramento
delta this morning and gusting as high as 30 mph at travis afb.
The marine layer along the central california coast is deepening
as of this writing and time lapse satellite imagery shows the
inland invasion of low stratus into the coastal valleys. These
are excellent indicators of a definitively cool change in the
weather across the entire CWA during the next 24 to 48 hours.
We can credit this cooling to an upper level trough over the
pacific northwest. The trough will settle southward into the
golden state this weekend and finally shove the high pressure
ridge that's been baking us into texas.
Although cooler air will be infiltrating our CWA today, high
temperatures will still top the century mark over the southern
half of the san joaquin valley, the lower foothills of tulare
county and the kern county desert but it will be the last day of
triple digit heat in any part of our CWA until the middle of next
week. Sorry about that spoiler. Yes, 100-degree heat will indeed
make its return by Wednesday or Thursday in the san joaquin
valley, lower foothills and the kern county desert, so enjoy the
short-lived cool down. Sunday and Monday will be the coolest days
in this pattern with highs in the upper 80s to lower 90s in the
san joaquin valley. Minimum temperatures in the valley will be
very comfortable during this period with lows ranging from the
mid 50s to mid 60s. In the kern county desert, afternoon high
temperatures will stay below the century mark Sunday and Monday|
with lows generally in the 60s. Additionally, the cool change
will be accompanied by gusty west to northwest winds this weekend.
Gusts of up to 35 mph are likely through and below the passes on
the west side of the san joaquin valley this afternoon and evening
with a possible recurrence late Sunday into Sunday night. The
winds could also kick up some dust in a few locations west of
interstate 5. In the kern county mountains and desert, westerly
winds could gust to 40 mph or higher through and below the passes
The onshore flow will dwindle Monday and become offshore again
by Monday night or Tuesday as the high pressure ridge over
texas begins to builds westward. As the ridge retrogrades next
week, it will inevitably put us back in the frying pan. As we've
already indicated, widespread triple digit heat will return to
elevations at and below 2500 feet by Thursday. The pattern will
likely stagnate across central california in the 5 to 7 day period
as the high pressure ridge remains in control. During that time,
the models forecast an increase in activity over the tropical
regions of the eastern pacific with the possibility of a named
cyclone near the baja peninsula. Whether or not tropical moisture
from this system moves northward into california by next weekend
is questionable, but it's worth watching. Otherwise, it appears
that the high pressure ridge over the southwestern u.S. Will keep
central california dry in the extended forecast period.
Vfr conditions can be expected over the central california
interior during 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.
