Area Forecast Discussion
National Weather Service Sacramento CA
330 AM PDT Wed Aug 23 2017

.SYNOPSIS...
Hot and dry weather returns to the region later this week with
temperatures returning to well above average by the weekend.

&&

.DISCUSSION...
Some debris cloudiness left over from last evening`s thunderstorm
activity lingers across far northern California and portions of
the northern Sierra Nevada. Otherwise, skies are clear across the
region early this morning. Current temperatures are milder across
most of the area compared to 24 hours ago and range from the upper
40s in the mountain valleys to the mid 70s across the warmer
portions of the Sacramento Valley.

Low pressure that`s been parked along the central California for
the past several days is forecast to shift east into SoCal by
Thursday as a northern stream system approaches the PacNW. Enough
moisture and instability lingers for one more day of shower and
thunderstorm chances across the northern Sierra before the deeper
moisture and instability is shunted eastward.

Temperatures remain close to average the next few days, then
hotter weather returns for the weekend as high pressure
strengthens along the West Coast.

&&

.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)
Quiet weather pattern ahead for the long term forecast period. A
stable upper level ridge of high pressure positioned over the west
will provide clear skies and dry weather with above normal
temperatures across northern California. Temperatures are expected
to gradually cool closer to normal towards the middle of next
week.

&&

.AVIATION...
VFR conditions expected at the TAF sites the next 24 hours. Some
mid to high level clouds early in the TAF period will gradually
diminish through the day for valley terminals. Winds 5 to 10 kts
with gusts up to 15 kts except for 30 kts through the delta.
Afternoon thunderstorms and CB possible for the mountains.

&&

.STO WATCHES/WARNINGS/ADVISORIES...None.
