AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
400 AM PDT Sat Mar 28 2015

.Synopsis...
Mainly warm and dry weather will continue into next week for most
of the region. Weak systems may bring a few showers to the
mountains this weekend into early next week.

&&

.Discussion...
The high pressure ridge has shifted eastward as an approaching
trough moves towards the Pacific NW. North winds could be a bit
breezy this afternoon on the western side of the valley. This
system is weak with little moisture for NorCal. However, it could
bring a slight chance of light convective showers limited to the
Sierra Crest south of Tahoe this afternoon/evening and again on
Sunday aftn/eve. Temperatures will trend cooler than yesterday,
but still remain above normal as valley highs range upper 70s to
low 80s with higher terrain in the 60s & 70s. Temperatures warm
back up by 2-4 degrees on Sunday with weak ridging over NorCal.

A second weak wave will approach the west coast on Monday and move
inland on Tuesday. Expect temperatures to slightly cool again on
those days (yet still be above normal) while a slight chance of
mountain showers brushes Shasta County on Tuesday. JBB

.Extended Discussion (Wednesday through Saturday)

Broad weak upper trough continues over the region Wednesday
beneath the larger scale ridge along the west coast. Looks like
precipitation chances will be mainly limited to areas near the
Oregon border and temperatures will be close to normal. Ridging
returns late in the week for a gradual warm-up.

&&

.Aviation...

VFR conditions next 24 hours. Dry cold front moves south through
the area this morning accompanied by a few clouds. Surface winds
turn northerly 10-20 kts behind front today.

&&

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