Area Forecast Discussion
National Weather Service Sacramento CA

.KEY MESSAGES...

 - Dry weather expected next 7 days with a return to widespread
   Valley fog/low clouds and warm/dry weather at higher
   elevations.

&&

.DISCUSSION...

...Today...

A stream of high clouds lingering over the Valley is evident on
satellite imagery early this afternoon, with otherwise dry and
mostly sunny conditions and seasonable temperatures persisting
throughout interior NorCal today. Valley fog development is
expected overnight and into Monday morning, although some
uncertainty regarding areal coverage remains. Resultant HIRES
guidance continues to show a 40 to 60 percent chance of visibility
reductions below a half mile across the Delta, central/southern
Sacramento Valley, and northern San Joaquin Valley.

...The Week Ahead...

A stationary ridge continues to amplify across the West Coast
into this week bringing potential for persistent low stratus and
fog to the Valley. Areas above the stratus (upper foothills and
mountains) will see above normal temperatures, dry conditions, and
breezy to gusty east-northeast winds overnight into the early
morning. Low daytime humidity and limited overnight recovery will
be likely in higher elevation areas where fog and low clouds
remain nonexistent. Overall light winds are expected elsewhere
throughout the week although a period of breezier north winds is
possible late in the week with a 20 to 40 percent chance of gusts
up to 20 mph in the northern Sacramento Valley. Depending on the
extent of these breezier Valley winds, persistent fog and low
stratus may be inhibited later in the week.

&&

.AVIATION...

VFR conditions through 10z for each site, with light and variable
winds. Around 10z through 12z FG/BR develops and spreads through
the sites, with 2SM to 5SM for each site around Sacramento towards
RDD. SCK and MOD have the best chance to see quarter to half mile
visibilities around 10z through 18z tomorrow. Skies generally
clear out after the TAF period.

.STO WATCHES/WARNINGS/ADVISORIES...
None.
