Area Forecast Discussion
National Weather Service Sacramento CA
933 AM PDT SUN SEP 11 2016

.SYNOPSIS...
Cooling trend through Tuesday with a slight chance of mountain
showers or thunderstorms. Dry Wednesday through Saturday with
temperatures warming back above normal by the end of the week.

&&

.DISCUSSION...
Trough of low pressure is deepening over the area today and
helping to keep the delta breeze up today. This will result in
cooler temperatures starting today. Highs may only be in the low
to mid 80s for Sacramento region to the lower 90s for the north
end of the valley. Moderate to locally strong delta breeze will
continue into Monday morning and will help to bring a chance of
low clouds into the Sacramento region Monday morning.

The low pressure area will continue to deepen over the west coast
Monday and Tuesday. Monday and Tuesday's temperatures will feel a
bit more fall like than summer. The trough is mostly dry but will
bring some chances of showers and thunderstorms along the crest
Monday and Tuesday along with some breezy ridgetop winds along the
crest late today and Monday. The best chance for thunderstorms
look to occur on Tuesday from around I-80 southward and should
contain some rainfall with them.

The low will move eastward Tuesday night and Wednesday with warmer
and dry conditions but temperatures still remaining a little
below seasonal normals for this time of year.

&&

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)

Warming returns to interior northern California as an upper level
ridge from the eastern Pacific extends into our area. As a result,
dry conditions and above normal temperatures are expected.

10 knots exc gusts 15-30 kts thru the Delta. Areas SW winds 15-25
