.SYNOPSIS...
Steady snowfall in the Sierra Nevada will taper to snow showers as
a storm system moves away from Central California this afternoon.
A warmer and wetter storm system will impact the forecast area,
starting Saturday afternoon and persisting into Monday. Most of
this precipitation will fall Saturday night through Sunday night.

&&

.DISCUSSION...
An upper-level area of low pressure will be centered near the
California/Nevada border this morning. This atmospheric
disturbance may be responsible for an additional four to eight
inches of snow in the Southern Sierra Nevada this morning.
Precipitation will become more showery in nature this afternoon as
the area of low pressure aloft moves to the northeast. An Eastern
Pacific ridge of high pressure will approach the west coast of the
United States tonight. This ridge of high pressure will progress
eastward across California Saturday.

A storm system will remain offshore of the west coast of the
United States Saturday night into early next week. Prolonged
southwesterly flow will continue to feed abundant moisture into
Central California. This will be a warmer storm system, with snow
levels around 7000 feet. Three to six inches of rainfall is
conceivable in the Southern Sierra Nevada foothills and the
Southern Sierra Nevada below 7000 feet. Forecast confidence is
increasing regarding the potential for several feet of high
elevation snow. Rain amounts the San Joaquin Valley will decrease
from north to south. One to one and a half inches of rain is
possible in Merced, Madera, and Fresno Counties. One half of an
inch to inch inch of rain is conceivable in Kings and Tulare
Counties. One quarter of an inch to one half of an inch of rain is
possible in Kern County. The majority of precipitation will fall
Saturday night through Sunday night.

The aforementioned storm system will finally move onshore Tuesday
night or Wednesday. Any precipitation Monday night through
Wednesday should not be heavy. A brief break in precipitation is
expected Wednesday night through Thursday night as a ridge of high
pressure progresses eastward through the Western United States.

.AVIATION...

morning. Closer to the mountains, IFR or lower ceilings will raise
to MVFR category this morning, before dissipating this afternoon.
Mountain obscurations will persist into tonight, before clearing.
