AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
205 PM PDT Tue Sep 30 2014

.Synopsis...
Dry and warmer weather this coming week with breezy northerly
winds during the middle of the week as high pressure rebuilds
across the region.

&&

.Discussion...
Temperatures are running just a few degrees warmer today than this
time yesterday with mostly sunny skies. A weak short wave is
beginning to clip northern California which will bring some
cloudiness for the northern mountains and northern Sierra. North
winds will begin to increase later this afternoon/evening as the
wave brushes through. Strong high pressure will then build behind
the shortwave, which will further increase surface pressure
gradients. This will allow winds to become breezy to locally windy
across the northern mountains and northern Sierra slopes, and also
along the western side of the Sacramento Valley and foothills
beginning Tuesday night and continuing through Thursday morning.
Winds are expected to decrease Thursday but light north winds will
continue through the end of the week.

Temperatures will trend a few degrees warmer Wednesday and trend
upward through the rest of the week as warm, dry winds and a much
warmer air mass influences the region.

&&

.Extended Discussion (Saturday through Tuesday)

Strong, warm high pressure will continue to sit over Northern
California, bringing well above normal temperatures for the
weekend and into early next week. The peak of the heat looks to be
Saturday, before the ridge flattens out a bit for Sunday and
Monday allowing for a few degrees of cooling. Light north winds
will continue to dry out the region through Monday. Models are
hinting at a weak closed low off the coast early next week which
could bring some additional cooling for Tuesday.

&&

.Aviation...

VFR conditions next 24 hours. Mainly northerly winds increasing
today with sustained surface winds 10 to 25 knots higher
terrain and west side of the Sacramento valley beginning after 06z
Wednesday. Winds will peak Wednesday morning through Wednesday
afternoon.


&&

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