Area Forecast Discussion
National Weather Service Sacramento CA
1006 AM PDT TUE AUG 30 2016

Dry weather with below average temperatures this week. Locally
breezy at times.


No changes to this morning's forecast package. Had some virga that
tracked across Shasta County this morning, but no reports of
actual precipiation or thunderstorms from the short wave that
moved over NorCal. Expecting mild and dry weather for the rest of
this week with locally breezy conditions (mainly delta &
ridgetops) as the main trough continues to linger over the West
Coast. JBB

.Previous Discussion...Mostly cloudy skies across interior NorCal
early this morning as high-level moisture moves northward ahead of
the low off the BC coast. Steady onshore flow continues through
the Delta with winds gusting above 20 kts at KSUU, but the
increase in cloud cover is resulting in milder temperatures across
most of the area.

Satellite imagery shows the short-wave presently off the NorCal
coast which will move rapidly across far northern California this
morning. Forecast soundings show plenty of moisture above 500 mbs,
but dry below, and only minimal elevated CAPE. Expecting the most
we'll see will be abundant virga.

Trough deepens along the West Coast through the remainder of the
week as the low is forecast to eventually make it southward into
the PacNW by Friday. Dry weather expected with below average
temperatures and locally breezy southwest winds.


NorCal will be under the influence of a longwave trough axis
overhead through the weekend. This will continue below normal
temperatures. No precipitation expected. By the end of the
weekend into early next week, the trough axis pushes east into
the Great Basin and ridging may gradually build in, bringing a
warming trend in temperatures and more northerly flow. JClapp/CEO



VFR conditions across TAF sites next 24 hours with some high
clouds today ahead of upper level trough. SW flow aloft with gusty
ridge winds and gusts up to 30 knots into Delta. JClapp
