   next several days

.DISCUSSION...

...Today - Sunday...
Stratus/Low clouds were more of the story this morning vs. fog
dominating the forecast yesterday but still impacting much of the
Central Valley and adjacent lower foothills. Out forecast remains
on repeat with another round of low clouds/fog tonight into
tomorrow morning with best chances Sacramento northward although
fog is possible throughout all of the Valley.

Dry weather and seasonable temperatures are forecasted for the
region, with upper 40s to 50s in the Valley and foothills, and
40s to 60s in the mountains for the daytime highs. Highs are
trending several degrees cooler than initially forecasted due to
the persistence of the fog/low clouds, keeping max temperatures
from being fully actualized.

...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 (mainly for areas outside of stratus/fog
development). Dry conditions will continue through next week.
Some ensembles are indicating a weak 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 continues
into this evening, although some sites may very briefly return to
VFR conditions around 22-24Z. Another round of BF/FG and low
stratus returns tonight after 03Z and continues through Sunday,
with areas of MVFR/IFR conditions. Areas of LIFR in fog and low
ceilings around 12-18Z, particularly in the Central Valley from
Sacramento southward. Lingering low ceilings in stratus expected
to persist through the day. Light and variable surface winds less
than 12kts.
