.DISCUSSION...

...Today-Friday...
GOES-WEST imagery once again shows lingering patchy fog and low
stratus this afternoon. Another round of dense to patchy fog is
expected across the Delta, Sacramento Valley, northern San Joaquin
Valley, and adjacent foothills Thanksgiving morning. Currently the
most widespread dense fog looks to occur north of Interstate 80,
with a 50-70% chance of visibilities less than a half-mile.
Seasonably high temperatures continue through the end of the week
with periods of offshore winds are expected to continue as well.

...This Weekend - Early Next Week...
Mountain precipitation chances continue to trend downwards for
this weekend in the NBM. Currently, less than a tenth of an inch
of rain is expected anywhere within the northern Sierra. We are
still expecting breezy north winds Sunday into Monday, though
gusts during that time have also trended down in the latest
forecast; the Valley is looking at gusts less than 25 mph
everywhere, with mountain peaks seeing up to 35 mph gusts
periodically. Breeziest conditions will occur in the evening
Sunday and overnight into early Monday morning. Otherwise, early
next week sees a return to calm and dry conditions with near
normal temperatures.
