426 AM PST Sun Mar 1 2015

Drier and warmer Tuesday onward.

.Discussion...
Radar showing that shower activity has significantly diminished
from yesterday as the storm has tracked into SoCal. Some light
snow showers are near the Sierra Crest south of Lake Tahoe which
will dissipate later today. Daytime highs will be near to slightly
above normal for our region with valley highs in the mid to upper
60s and mountain highs in the 40s and 50s. Breezy northerly winds
along the western Sacramento valley this morning into afternoon,
but they will lessen by this evening.

A secondary wave of light precipitation will track southward
across CA on Monday. The models have recently showed the track
hugging the coastline instead of coming straight over interior
NorCal as before. Thus, have lowered the chance of precipitation
for this Monday event. Snow levels will be around 5000 ft on
Monday, but snow accumulation is forecast to be quite
light...parts of the Sierra could see around an inch.

For Tuesday into Wednesday, warmer and dry with daytime highs
going a little above normal and light winds.  JBB

.Extended Discussion (Thursday through Sunday)

Medium range models show dry weather through this coming weekend
as upper ridging builds over NorCal. Winds are expected to be
relatively light and terrain driven. High temperatures in the
Central Valley are expected in the upper 60s to lower 70s with
mostly 50s to 60s for the mountains and foothills.

Extended models continue to hint at a trough slowly drifting
eastward near NorCal mid to late next week (11th to 13th
time frame).     JClapp

.Aviation...

Upper low moves into SoCal today. Increasing surface pressure
gradient from MFR-SAC is generating breezier northerly boundary
layer winds (SFC-030). No fog except some shallow fog in eastern
Valley south of Beale AFB. Some scattered low to mid clouds
(bases 040 to 080) today southward of Sacramento area.   JClapp

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