.DISCUSSION...

...Today-Friday...
Current GOES-West visible satellite imagery illustrates the
blanket of stratus in the Central Valley gradually eroding, with
some high clouds passing overhead from the north. Visibilities
have improved across the Central Valley this afternoon, however
you can expect another round of patchy dense fog and low clouds
once again tonight into Friday morning. High resolution guidance
suggests the best potential from Marysville southward. Dry weather
and seasonable temperatures are forecast for the region, with 50s
to 60s in the Valley and foothills, and 40s to 60s in the
mountains for the daytime highs.

...Friday Night-Sunday...
A weak system passing to the north over the weekend may bring
some isolated, light showers to the Shasta County mountains,
however little to no impacts or accumulations are expected.
Elsewhere, dry conditions will persist over the weekend with daily
chances for fog, mist and low clouds especially in the Valley.
High temperatures are forecast to be in the 40s to 60s across
interior NorCal.

...Next Week...
High pressure builds across the region next week, allowing for a
gradual warming trend with high temperatures warming to the 50s
to near 70 (most noticable for areas outside of stratus/fog
development). Dry conditions will continue through next week. Some
ensembles are indicating a pattern change in mid December but
there is a large amount of uncertainty as it is too far out in
time.

.AVIATION...
Lingering low cigs and mist across the Central Valley this
afternoon and evening, although some sites may briefly return to
VFR conditions (mainly across the northern Sacramento Valley).
Another round of BF/FG and low stratus returns tonight after
08-15Z, with areas of MVFR/IFR conditions, locally IFR,
particularly from Sacramento southward. Light and variable surface
winds less than 12kts.
