.DISCUSSION...

...Today - Friday...
Current GOES-West imagery shows a broad stratus deck enveloping
the Delta, Valley, and adjacent lower foothills this afternoon.
Any lingering patchy fog and reduced visibilities will continue to
improve through the remainder of the day, with additional dense
fog development anticipated this evening into Friday morning.
Probabilities of visibilities less than a half-mile currently sit
around 50 to 70 percent throughout the Delta, Valley, and adjacent
foothills locations. Aside from periodic fog development, cool
and dry weather are expected to persist through the end of the
week as well.

...This Weekend - Next Week...
While a slight chance for isolated mountain showers remains
possible late Saturday into Sunday, predominantly dry weather is
expected to continue this weekend into early next week. Breezy
north to east winds will be possible Sunday into Monday as well,
although strongest wind gusts up to 35 mph are expected along the
Sierra at this time. With a more persistent offshore wind pattern
setting up late weekend into next week, fog development is
expected to be lesser relative to this past week. Otherwise,
seasonable temperatures look to persist. Ensemble guidance then
indicates some potential for a trough retrograding toward the west
coast around the middle of the week. While uncertainty remains
high at this time, potential for breezier north to east winds and
another slight chance for mountain showers will be possible.
