Area Forecast Discussion
National Weather Service Sacramento CA
333 AM PDT FRI JUN 10 2016

.SYNOPSIS...
An upper level trough will bring continued cooler temperatures
today and Saturday. Temperatures will warm up early next week
with some chances for thunderstorms northern Sierra Sunday.

&&

.DISCUSSION...
Upper low off the Pacific Northwest coast continues to edge slowly
eastward. Some mid level cloudiness currently showing up over the
northern CWA but still believe any precipitation will remain north
of the CWA today. Daytime highs today will continue to cool with
max temperatures coming in a few to several degrees below normal.
Looking at satellite fog product and Fort Ord profiler it appears
marine layer has become somewhat mixed out so any stratus in the
delta or southern Sacramento valley is likely to be quite patchy
this morning. Upper trough axis is forecast to shift east of the
CWA by Saturday afternoon turning main flow from onshore to
northerly on Saturday. Surface progs show a moderate northerly
gradient but with upper trough still over west coast the upper
level support for northerly wind will be limited. Still...breezy
north winds are expected on Saturday especially down the west side
of the Sacramento valley. Combined with fairly low relative
humidity and continued low fuel moistures...this will make for
increased fire danger and a fire weather watch will remain in
place for much of the Sacramento valley Saturday. Main upper
trough axis shifts into Nevada on Sunday leaving the northern
Sierra in close proximity to this axis and associated instability.
Therefore...thunderstorm threat will continue there. Elsewhere...a
lighter surface gradient and warmer airmass will bring warming
with lighter winds on Sunday. Even with the lighter
winds...afternoon RH values will remain quite low with single
digit RH still possible northern Sacramento valley in the
afternoon. Temperatures warm a bit more on Monday as flat upper
ridging moves over the area while more subsidence and more stable
conditions end Sierra thunderstorm threat.

&&
.EXTENDED DISCUSSION (Tuesday THROUGH Friday)

Upper level winds shift more from the southwest Tuesday through
the end of the week as an upper trough gradually deepens off the
Pac NW coast. As a result, temperatures will cool into the 80s for
the Central Valley with 50s and 70s elsewhere. Expect moderate to
strong Delta Breeze and ridge wind speeds throughout the week as
the trough nears the coast. Also, a shower threat exists mainly
over the Shasta county higher terrain Thursday and Friday due to
the upper level disturbance.      JClapp

&&

.AVIATION...

Upper trough just offshore, but Ft Ord and Bodega Bay profilers
show mixed out marine layer. Dewpoint depression in Srn Sac Valley
still warrants a chance of stratus at KSAC and KMHR this morning
w/ typical bases approx 012-014 between 12z- 15z, but patchy
stratus may not form ceiling. Northerly boundary layer winds begin
Fri evening increase Sat.     JClapp

&&

.STO Watches/Warnings/Advisories...
Fire Weather Watch from late tonight through Saturday evening
for Central Sacramento Valley in Glenn, Colusa, Yuba, Northern
Sutter, and Butte County Below 1000 Ft-Northern Sacramento
Valley to Southern Tehama County Line Below 1000 Ft-Southern
Sacramento Valley in Yolo-Sacramento Far Western Placer,
southern Sutter and Solano County Below 1000 Ft.
