Area Forecast Discussion
National Weather Service Sacramento CA
338 PM PDT FRI JUL 22 2016


.SYNOPSIS...
A warming trend continues through next week with highs 5 to 10
degrees above normal. No precipitation is expected through the
next 7 days.

&&

.DISCUSSION...
The relatively cool weather pattern is at an end for a while as
the Pacific Northwest trough starts to shift eastward and upper
level ridging over the south and central plains expands into the
region. Temperatures are a few degrees higher than yesterday for
most spots. There is a weaker Delta breeze so typically influenced
area will notice less cooling overnight tonight. Light northerly
winds over the northern and central Sacramento Valley and the
surrounding foothills will bring warmer temperatures to those
areas, with some spots remaining in the mid 60s to around 70.
After a warm start, there will be widespread triple digit highs in
the Valley, though record heat is not expected.

A weak shortwave trough should bring a bit more Delta flow on
Sunday and Monday, so the Delta and Sacramento area may actually
be a little cooler. Locations elsewhere should be warmer, though,
with Redding forecast to hit around 106.

Further heating occurs on Tuesday as the ridge building returns.
Little or no Delta breeze is expected. No precipitation is
expected with a dry airmass. EK

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)



The presence of the upper level jet stream will continue to be
absent across northern California as an upper level high pressure
system builds and retrogrades west during the long term forecast
period. High temperatures will return to the upper 90s to mid
100s in the Valley, which near normal for the northern Sacramento
Valley and 5 to 10 degrees for the southern Sacramento valley and
Northern San Joaquin Valley. Dry air will remain in place with
minimal cloud cover and no chances for precipitation.


&&

.AVIATION...


VFR conditions are expected for the terminals during the next 24
hours. Light wind shifts are expected through the forecast period.

&&

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