.DISCUSSION...
Thanksgiving was a day to give thanks as the stratus finally
broke in parts of the Valley. However, fog has begun or started
to show up on imagery in the southern Valley as of midnight. A
Dense Fog Advisory has been issued through 10 AM due to high
confidence of visibilities less than 1/4 mile. However, with the
ridge of high pressure weakening today as a shortwave rides
through the Pacific Northwest, the fog should be easier to clear
allowing temperatures to climb. There is a 60 to 95 percent
chance in the NBM of highs of at least 60 degrees in the Valley
today.

Model ensembles have a better agreement of this weekend as a
cutoff low slides under the ridge through Saturday before making
a right turn and hanging over the Pacific. At the same time,
another trough begins sliding from the Pacific Northwest late
Saturday to the Great Basin by Monday. However, the ensembles
diverge as to how far east in the Basin the trough will be. No
precipitation is expected from either troughs.

Tuesday through Thursday brings a third trough which the
ensembles agree takes an inside slider approach over the Sierra
Nevada. However, there is a 25 percent chance or less of any
precipitation on Wednesday and Thursday for the Valley with this
system. Snow probabilities are also low at 25 to 40 percent
chance of any accumulation above 7,000 feet.

.AVIATION...
IFR to MVFR ceilings and visibilities will persist in most
Valley locations through 18Z Friday. After 18Z, conditions will
improve especially after 20Z. However, MVFR to IFR conditions
return between 6Z and 9Z Saturday for the overnight hours.
