Area Forecast Discussion
National Weather Service Sacramento CA
302 PM PST Mon Nov 28 2016


.SYNOPSIS...
Dry weather with locally breezy north wind returns this week as
high pressure builds along the West Coast. The exception will be a
weak system that may bring a few showers to the northern mountains
on Wednesday.

&&

.Short Term Discussion (Tonight through Thursday)...
Dry weather weather with seasonably cool temperatures expected
for the remainder of the week as high pressure over the eastern
Pacific dominates the pattern. The exception will be a weak system
that is forecast to move through the ridge on Wednesday bringing
a chance of showers to the northern mountains, north of I-80.

Northerly flow increases over NorCal tonight into Tuesday and will
likely preclude much fog development. More north winds expected
across the area on Thursday in the wake of Wednesday`s system. I
lull in the northerly wind exists Wednesday with the weak system,
which will likely allow more significant fog to develop.  JClapp

.EXTENDED DISCUSSION (Friday THROUGH Monday)
Broad upper level ridging is forecast to dominate our weather
during the start of our extended forecast. Temperatures on Friday
are expected to be in the mid to upper 50s which is near to
slightly below normal. Heights gradually build into Saturday which
will provide a few degrees of warming over Friday. By Sunday, an
approaching trough from the Pacific Northwest will skirt past our
area and may provide a few light showers to our northern mountains
late Sunday but the best dynamics will be well to our north.
Showers may continue for the northern mountains into Monday but
the rest of our area is expected to remain dry with temperatures
near normal.  Wilson

.AVIATION...
Clearing skies and mainly VFR conditions expected for the valley
next 24 hours as atmosphere drys under NW flow aloft. At the
surface, northerly flow will continue through tomorrow and should
limit fog development overnight. However, eastern portions of the
valley (south of SAC) sheltered from the N winds could see fog
develop early tomorrow morning. For now, confidence is not high
enough to include it at TAF sites.

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