AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
905 PM PST Tue Dec 17 2013

.Synopsis...
Temperatures trending closer towards normal beginning tomorrow
with a chance of showers for the Sierra Wednesday night into
Thursday. Windy conditions Thursday.

&&

.Discussion...
A weak low pressure area off the coast is helping to spread some
high clouds over the region tonight. As the next system approaches
from the north the clouds over the area north will be pushed to
the south and east towards morning. The clearing skies might
allow for some patchy fog to develop near the water ways during
the morning.

A very weak system will drop down from the north and may produce
some showers over the region...mainly for the mountains with only
slight chances for showers in the valley. The timing is still
on track for Wednesday night and Thursday for the system to move
through. Winds will pick up behind the system starting early in
the day on Thursday. Wind Advisories look likely for Thursday.
Winds generally look like they will increase to 20 to 35 mph with
gusts up to 45 mph. The strongest winds will be on the west side
of the valley. Gusty northeast to east winds are expected to
increase during the day in the mountains as the system moves
southward during the day. The winds will gradually taper over
night and Friday.

A weak wave pushes through the Pacific Northwest during the
Friday/Saturday time frame. The NAM is a little faster than the GFS
and also slightly further to the west and is indicating the
possibility of some showers Friday afternoon over the mountains.
The GFS is slower and tires to keep any precipitation just east of
the area.

.Extended Discussion (Saturday through Tuesday)

Medium range models continue to advertise a high-amplitude ridge
remaining quasi-stationary off the West Coast through early next
week. This will continue to bring northerly winds across northern
California. Weak shortwave troughs will pass by the region over
the weekend and again early next week, but the bulk of
precipitation should generally remain north and east of the
forecast area. High temperatures should remain above normal
through the extended forecast period.

Dang

&&

.Aviation...

High pressure continues over the area with scattered to broken high
clouds. This will limited fog formation this morning. Expect mainly
VFR conditions except for areas of HZ/BR over the northern San
Joaquin Valley with MVFR in fog through 18Z. Potential for more
widespread fog Wed morning if high clouds stay away.

JClapp/Dang

&&

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