333 pm pst Thu nov 15 2018

Synopsis
Dry with near normal temperatures through early next week except
in areas of heavy smoke due to the camp wildfire. Breezy
northeasterly winds over the sierra nevada Saturday night into
Sunday elevating fire danger. Cooler temperatures next week with
increasing chances of precipitation across interior norcal by mid-
week.

Discussion
A strong dome of high pressure over the eastern pacific and west
coast will bring dry conditions across the region. Temperatures
should be below normal over most locations outside of mountain
locales given heavy smoke spreading from the camp fire. Reduced
solar insolation from wildfire smoke in these locations will keep
daytime highs over the next couple of days below normal for this
time of year. The other impact of this wildfire smoke will be
decreased visibilities throughout the central valley impacting
aviation. At this time, the worst area of visibility is around
oroville and yuba city regions where visibilities are reported at
1 2 mile. Smoky valley conditions are likely to continue Friday
and possibly even Saturday given light winds and stable
atmospheric conditions.

Models in fairly good agreement in dropping a shortwave trough
southeastward through the pacific northwest into the central great
basin on Saturday with high pressure rebounding over the west
coast by Saturday night. The combination of northeast to easterly
flow aloft and a tight northeast surface gradient across the
sierra will bring breezy northeast winds Saturday night especially
to the higher elevations and favorably oriented sierra and
foothill canyons. These breezy winds will bring elevated fire
danger will be short lived with winds decreasing by Sunday
afternoon. As such, a fire weather watch is in effect for these
mentioned locations, including the camp fire. The brief wind
event may be sufficient enough to mix some of the smoke out of the
valley on Sunday so this region may see a little more Sun during
the second half of the weekend. &&
.Extended discussion (Monday through Thursday)
increasing potential for measurable rainfall sometime during the
middle to latter part of next week.

The upper ridge is forecast to progress into the central great
basin Monday while split flow ensues across the eastern pacific.

The latest guidance depicts one upper low shearing across socal
on Tuesday while a broader scale trough looms farther offshore.

At this point, medium range models continue to diverge with the
timing of this system. The european has been consistently ahead
of the GFS carrying the short wave trough into norcal Wednesday
with ridging returning by the following day, while the gfs
maintains upper ridging. GEFS and naefs ensembles show upper
troughing similar to european, but slower progression with the
wave moving inland on thanksgiving. As mentioned above, rainfall
chances will be on the increase by the middle of the week, albeit
with significant timing uncertainty.

Aviation
Winds have remained fairly stagnant through the early afternoon
hours and with smoke billowing from the camp fire, conditions have
been bouncing between MVFR and lifr conditions. Look for these
conditions to continue into tomorrow morning.

Sto watches warnings advisories

afternoon for northern motherlode from 1000 to 3000 ft. Includes

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.
