Area Forecast Discussion
National Weather Service Sacramento CA
826 AM PDT FRI AUG 26 2016

.SYNOPSIS...
Dry weather pattern with near normal temperatures for the next
week.

&&

.DISCUSSION...
Dry northerly flow aloft has settled into Northern California this
morning behind a weak upper level trough over SoCal. Clear skies
prevail over the region, except the usual coastal stratus reaching
into the western Delta this morning.

The trough will shift south and east the next few days, allowing
for a shortwave ridge to rebuild into California. As such, expect
a modest warming trend to occur through the weekend. High
temperatures will reach the upper 80s to mid 90s across the
Valley, with 70s and 80s over the mountains. These forecast
temperatures are within a few degrees of normal. A few
thunderstorms may form this afternoon along the high Sierra,
mainly from Alpine County southward.

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)

A short wave trough should approach interior northern California
early next week. Model differences still exist regarding the
progression of the approaching trough, with the GFS being the
fastest solution. A deeper wave will move along the West Coast by
midweek, resulting in synoptic cooling during the extended
period. Temperatures will be near to below normal temperatures
next week. Precipitation chances are low at this point, given that
the air mass looks to be dry for convection.

&&

.AVIATION...

VFR conditions across TAF sites next 24 hours. Generally light winds
except for gusts up to 25 knots near the Delta region.


&&

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