Synopsis
High pressure will maintain dry and stagnant conditions with
valley inversions through the weekend. A pattern change will bring
increasing changes for gusty winds, valley rain and mountain snow
Wednesday to Friday. Plan for travel impacts and winter driving
conditions over the thanksgiving holiday weekend.

Short term
No big changes to the forecast for the start of next week.

Hazy skies from the camp fire smoke should clear tonight with a
light east flow. Smoke from the camp fire could return by
Tuesday, especially for lassen and plumas counites as winds start
to increase from the south.

Aside from the haze, the weather will remain rather quiet under
high pressure through Tuesday. Valley inversions will limit
warming and keep some haze near population centers. Afternoon
highs will be in the 50s to near 60 across the region with
overnight lows in the teens and 20s. Brong

Long term Wednesday onward...

*synopsis:
a pattern change is upon us starting the middle part of this
coming week, which is just in time for thanksgiving weekend and one
of the busiest travel days of the year. The strong ridge that is
currently over the western coast of the u.S. Will finally break
down this coming week allowing a series of shortwave troughs to
make their way into the western u.S. The first weather system will
affect our region beginning Wednesday morning and lasting through
Thursday. The second system will affect our region Friday morning
into Saturday. The third and fastest moving system will make its
way across our region Sunday. These weather systems do not
particularly look strong, however, precipitation totals could add
up noticeably with each passing shortwave.

*winds:
the eastern sierra and western nevada valleys will experience
blustery conditions ahead of the first disturbance Wednesday
morning into Thursday. Turbulence will also be possible above and
downstream of the sierra nevada during this time. Gusty winds are
likely through the weekend, with speeds increasing Friday through
Saturday ahead of the second system. Winds with the third and
fastest moving shortwave do not look to be as strong as with the
previous shortwaves. Did not make extensive changes to the
previous forecast regarding winds.

*precipitation:
a series of shortwaves will pass over our region bringing rounds
of rain for the lower valleys of western nevada and snow to the
sierra nevada. Current model guidance, including ensemble guidance
from the GEFS and eps show that snow levels will likely drop to
near 6000-6500 feet msl in the sierra. In cloud evaporation and
melting of snow could push snow levels down as low as 5500 feet.

This means that areas including geiger grade, virginia city, and
higher elevation areas along u.S. 50 and 395 could see brief
periods of snow. It is too early to pin down QPF and snow totals
due to modest run-to-run model variability. However, with the
thanksgiving holiday weekend being one of the busiest travel
periods of the year, wide-ranging travel impacts can be expected.

Aviation
ExpectVFR conditions today with light winds. Slantwise visibility
could be reduced at times due to smoke haze trapped beneath
inversions. Light westerly winds may push smoke haze over the
sierra nevada from the camp fire in northern california. However,
the depth and visual reduction due to this smoke looks minimal.

Dry conditions are expected Monday and Tuesday ahead of a series
of weather systems, which will affect our region Wednesday through
next Sunday. Gusty surface winds, turbulence, and mountain
obscurations due to precipitation are all possible Wednesday
through Saturday. Please refer to the long term discussion for
more details.

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.
