AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1020 PM PDT SAT AUG 29 2015

.SYNOPSIS...
Cooler and drier conditions with below normal temperatures next
week.

&&

.DISCUSSION...
Drier air has moved into NorCal this evening with clear skies now
over the area. Moderate delta breeze is bringing much cooler
temperatures with readings 5 to 15 degrees cooler versus yesterday
at this time. Current forecast is on track and no update will be
needed.

.PREVIOUS DISCUSSION...
A weak system moved through the region earlier has brought cooler
air and a few showers to the interior. A few post frontal showers
or even an isolated thunderstorm will be possible over the
northern mountains the remainder of the afternoon but in general
expect dry conditions for most locations. Temperatures are
running a lot cooler today down 10 to 15 degrees from yesterday.
Clouds will clear from west to east late in the day into the early
evening hours.

The current trough over the region will lift northeast on Sunday
but another trough will drop down along the coast from Canada
early next week to help keep temperatures cooler than normal to
near normal through at least mid week. The trough does not look
like it will bring any precipitation to our area at this time.

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)

Northern California will remain under the influence of a large
scale trough pattern through the extended period. This will likely
keep temperatures below normal through the end of next week. The
GFS continues to hint at a deeper trough bringing precipitation to
far northern CA late next week. The consensus suite of models
leaves things dry however, and our forecast hedges toward the
consensus.


DANG/JBB

.AVIATION...

VFR conditions continue. Generally light winds with gusts to 25
mph through the delta.

.STO WATCHES/WARNINGS/ADVISORIES...
