national weather service san joaquin valley - hanford ca
518 pm pst Mon nov 12 2018
updated air quality section

Synopsis A ridge of high pressure will remain over the
area for the next several days with continued dry weather.

Discussion Less upper level smoke transport into the forecast
area today however, lower level smoke from wildfires remains
trapped in the san joaquin valley and the west slope of sierra.

Visible imagery shows both the alder complex and eden fires
producing smoke however the transport thus far is limited. I
expect overnight as downslope flow to move some smoke into the
foothills and east side of the san joaquin valley. Meanwhile over
the kern county desert and mountain areas, dry easterly flow is
keeping skies clear, relative humidity low and winds locally
gusty.

Speaking of winds, speeds in the bear valley, cummings valley and
down the i-5 corridor from lebec to grapevine have been
consistently in the 30-40 mph range... Which is a bit weaker than
yesterday. All high resolution forecast models keep the easterly
flow and gusty winds blowing over the above mentioned areas
tonight and Tuesday morning with then a general diminishing regime
for Wednesday.

With the very dry airmass in place and no cloud cover, overnight
lows tonight will again be rather chilly with deserts in the 20s
in lower spots and low to mid 30s in the san joaquin valley. I
have included patchy frost in the forecast based on this mornings
observations.

So how does the pattern develop? Again, dry weather will continue
as both GFS and ECMWF models keep the high amplitude ridge of high
pressure over the area through Wednesday and then shift the axis
back to the west later in the week. Models then rebuild a high
pressure center off the pacific northwest coast over the weekend
and the ECMWF then tries to bring a weakening area of low pressure
under the high and off the california coast by Monday. GFS has a
similar solution today, however both the GFS and ECMWF models did
not have this solution yesterday. Confidence is increasing in a
pattern change next week, however how it changes is still way up
in the air. Will it be a dry closed low moving across socal per
the gfs... Or an open trough of low pressure moving across the
entire region with rain as depicted on latest ecmwf? Ending this
very long dry spell will happen sometime, maybe next week? I think
forecasting using model ensembles to get consensus first before
adding precipitation to the forecast is the best way to go today.

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.
