110 pm pst Tue nov 21 2017
Synopsis Dry weather and above normal afternoon temperatures
can be expected across the central california interior through
the holiday weekend. Patchy fog is possible in the san joaquin
valley during the late night and morning hours each day.
Discussion Weather remains benign over the region due to high
pressure in control, although dense fog development occurred this
morning in portions of the san joaquin valley in madera and
merced counties. The ridge of high pressure over the southwestern
us and northern baja will continue to strengthen and provide
additional warming to the central california interior. Just about
anywhere in our forecast area will experience well above average
temperatures through at least Saturday. Highs are expected to
reach to about a 15 to 20 degree anomaly above the 30-year
average, which is considered record territory. The warmest
locations will reach into the lower 80s, on both Wednesday and
thanksgiving day, especially in the central valley, lower
foothills, and the kern county desert. Even locations in the
mountains at an elevation of around 4,000 feet will rise to the
mid to upper 70s. Low temperatures will also be quite mild and
only reach the 50s in the warmest locations in the san joaquin
valley. Daytime highs are expected to lower slightly on Friday
and Saturday but will still remain well above average. Although
morning and nighttime fog is possible each day through Saturday
as long as the high pressure remains, it will likely be patchy
with mild overnight lows.
A low pressure system will arrive later in the weekend and push
east of the region by Monday. Models have been trending a faster
arrival, so a slight chance of showers and mountain snow in our
forecast area could begin by early Sunday morning or late Saturday
night. Forecast guidance continues to show that this system is
moisture starved and will likely weaken by the time it reaches the
southern portions of the san joaquin valley, or through the day on
Sunday. We added pops as far south as northwestern kern county,|
albeit a slight chance. The best chances for precipitation will be
over the sierra nevada towards yosemite and kings canyon.
On Sunday night into Monday, northwest flow aloft will allow low
clouds to bank up along the west northwest facing sides of the
tehachapi mountains and southern sierra nevada. So, relatively
cool weather (at least compared to this week's forecast), but
still with slightly above average daytime high temperatures, will
likely prevail for early next week. Another ridge of high pressure
arrives by next Tuesday, but it appears not quite as strong at
Record high temperatures

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.
