Area Forecast Discussion
National Weather Service Sacramento CA
1019 AM PDT FRI JUL 22 2016


.SYNOPSIS...
Near normal temperatures today then a transition to above normal
temperatures over the weekend and through next week. Highs 5 to
10 degrees above normal during this time. No precipitation
expected through the next 7 days.

&&

.DISCUSSION...
Another relatively cool start to the day today, but a warming
trend is already on the way. Temperatures are beginning to move
upwards, and at 10 am were a few degrees higher than the same time
yesterday for most spots. There is a much weaker Delta breeze and
some light northerly winds developing. This is due to the
persistent Pacific Northwest trough starts to shift eastward and
broad ridging spreading into the region. Highs this afternoon will
be noticeably warmer than in recent days, reaching around normal
levels for this time of year. Mid to upper 90s are expected across
the Valley, upper 80s and lower 90s in the foothills and 70s to
80s in the mountains. The weekend is on track to see widespread
triple digit highs, though record heat is not expected.

The weather overall looks dry well into next week, though there
are some hints with the GFS model that some monsoonal moisture
could potentially begin moving up the Sierra late next week. If it
happens this could bring some mountain showers, but confidence is
low at this point. EK

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)

High pressure from the Desert SW extends over Interior NorCal
next week resulting in above normal temperatures. Highs in the
Central Valley will generally be above 100 with mostly 80s to 90s
for the mountains and foothills. Forecast remains dry for now, but
will need to watch potential for monsoonal moisture to stream
northward over the Sierra Nevada late next week.

.AVIATION...

VFR conditions with light winds expected over the next 24 hours.

&&

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