Area Forecast Discussion
National Weather Service Sacramento CA
915 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...
A light northerly flow is expected today within the valley. This
will end up warming temperatures up to between 100 and 106
degrees for today. Marine layer is shallow and under 1000 feet
deep but stratus has been rapidly redeveloping along the coast
this morning.

The air flow will reverse direction for Sunday but inland areas
will remain hot and generally between 100 and 105. Sunday night
the delta breeze looks to be moderate to strong so that may help
to reduce temperatures slightly for Monday.

Tuesday is when the high pressure from the southwest begins to
build over our area and temperatures will likely be 105 to 110
degrees that day throughout the valley with the hottest
temperatures over the Northern Sacramento valley.

&&

.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.

&&

.STO Watches/Warnings/Advisories...
None.
