Area Forecast Discussion
National Weather Service Sacramento CA
330 AM PDT SAT JUL 23 2016

.SYNOPSIS...
Dry with a gradual warming trend through the week. Triple digit
heat expected in the Central Valley with high temperatures well
above normal.

&&

.DISCUSSION...
AMS begins to warm today in wake of short wave trough pushing
through the PacNW and upper high to the south expanding northward.
Highs expected to climb into the triple digits today in the
Central Valley, hottest around 105 in the Northern Sacramento
Valley. Warming also expected in the Delta region today as flow is
weak and marine layer very shallow.

Upper troughing progged to deepen slightly over NorCal Sunday into
Monday resulting in increased Delta breeze and minor deepening of
the Marine layer. This in turn will result in slight cooling
through the Delta and into the Southern Sac Valley Sunday and
Monday. Highs in the Sacramento area expected to lower into the
upper 90s Monday. Max temperatures throughout the remainder of
Interior NorCal likely to be near the same or slightly warmer
Sunday into Monday.

Upper ridging from the Desert SW combines with the EPAC high
Tuesday and expands northward over NorCal. High pressure then
continues to strengthen into Thursday. This will result in more
significant warming trend with highs climbing to around 110 in
the Northern Sac Valley Thursday. Max temperatures expected to be
upwards of 10 plus degrees above normal next week, but remaining
below record values.

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)

Upper level ridging remains over the western U.S through the
extended period for dry and very warm conditions through the end
of next week. Daytime highs will run anywhere from 5 to 10 degrees
above normal for late July but still below record values. Winds
generally light under the ridge. A slight cooling possible by next
Saturday as upper trough approaches the Pacific Northwest coast
increasing onshore flow. At this time...monsoon moisture appears
will remain south and east of CWA but some models bringing
precipitation up the Sierra by next Saturday. Have kept extended
dry for now.

&&

.AVIATION...

VFR conditions all terminals next 24 hours. Mainly northerly
sustained wind up to 15 knots.
