area forecast discussion
national weather service san joaquin valley - hanford ca
404 pm pst Tue dec 18 2018

Update Updated air quality issues section.

Synopsis
High pressure aloft will dominate the forecast area
through Thursday, giving us mostly clear skies and above average
temperatures, with morning fog possible the next two nights.

Friday onward, a more unsettled weather pattern begins with
marginal chances of precip in the sierra nevada this weekend.

Another chance of precip Monday night and into Tuesday as another
storm system arrives.

Discussion
We started off the day with patchy dense fog across many areas in
the san joaquin valley, which prompted a dense fog advisory that
expired at 11 am pst today. Things have cleared out since then,
with the exception of a few high clouds traveling with the
northwesterly flow aloft. Dense fog looks to be possible again in
the forecast tonight for the valley as high resolution model
progs have light winds, mostly clear skies, and high rh's. A
slight warming trend will occur over the next few days as 500 mb
heights slowly rise with the building ridge. Highs by Thursday
and Friday could be over 60 degrees for many areas in the sqv,
which would be 5-8 degrees above average for this time of the
year. Fog will also be possible Wednesday night and Thursday
morning.

Early Friday morning, a disturbance will mainly impact northern
california, but still may bring a marginal chance of precipitation
for the higher elevations of northern portion of the sierra
nevada in our cwa. Low-amplitude impulses are progged to move
through the region throughout the weekend, bringing slight chances
of precipitation in the sierra nevada. However, there is some
disagreement on when the precipitation could arrive in the models
at this time.

On Monday evening and into Tuesday, the ecm and GFS show a more
significant area of low pressure aloft swinging down from the
gulf of alaska. Models have been fairly consistent in their
development of this system, as well as a southeast trajectory into
california. There is uncertainty in the intensity of this system
-- if it remains a closed low or weakens into an open wave is not
clear at this time. Either way, it looks like it could bring a
chance of precipitation into the central california early next
week, but the exact timing and intensity of this storm system are
unknown this far out.

Aviation
In the san joaquin valley, expect areas of MVFR visibilities due to
haze and mist, except local ifr lifr in fog from 06z to 18z
Wednesday. MVFR ceilings with local ifr expected through 18z Wed due
to low clouds over the sierra foothills. OtherwiseVFR conditions
will prevail over central california through the next 24 hours.

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.
