AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
955 PM PDT WED AUG 26 2015

.SYNOPSIS...
Dry weather with daytime temperatures a little above normal
through the end of the week. Cooler temperatures beginning over
the weekend with a chance of showers over the northern portion of
the state. Above normal daytime highs continuing through Friday
followed by a cooling trend over the weekend.

&&

.DISCUSSION...

Max temps were generally some 4-9 deg above normal on Wed with
similar readings expected on Thu. A few sites (DTS,MOD,SCK) managed
to hit the century mark.

Another very warm/hot day is expected on Thu with with readings
approaching 100 degrees in many valley spots. Weak monsoon push
northward may be enough for an isolated thunderstorm over Alpine
county near the crest. Otherwise...clear and light winds over the
area.

Slightly cooler Friday...but still a few degrees above normal.
Clouds will increase and there is likely to be at least a moderate
late afternoon/evening delta breeze as trough digs south off the
coast. Moisture plume of 1.00-1.50 pwat will swing over extreme
northern California Friday night. Shower chances will be over the
northern Sacramento valley...north of Yuba City-Chico. Best
chances for rain will be Redding northward.

Slight shower chances continuing into Saturday northern valley
with trough swinging through the area...turning drier late
afternoon evening. Temperatures will be much cooler with readings
around 5 degrees below normal.


.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)

Large scale trough will linger off the West Coast into mid-week
with several waves riding southeast in the flow. Little effect
expected on NorCal as moisture remains removed far to the north.
This will result in dry weather and below normal temperatures into
mid-week. CEO

.AVIATION...

VFR conditions expected across TAF sites next 24 hours. Brief
period of MVFR conditions possible near Carquinez Strait Thursday
morning. Generally winds under 10 kts with the exception of
locally gusty SW winds across the Delta with gusts to 20-25 kts
possible.

&&

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