.DISCUSSION...
A trough of low pressure will deepen over the northern half of
California today. This trough of low pressure will be responsible
for scattered showers in the San Joaquin Valley and Sierra Nevada
foothills this afternoon. A Winter Storm Warning remains in effect
for the Sierra Nevada until 11 PM PDT this evening. Additional
snow accumulations should range from one to two inches from 4,000
to 5,000 feet, two to four inches from 5,000 feet to 6,000 feet,
and four to eight inches above 6,000 feet. The majority of this
snow will fall this afternoon. The pressure gradient should
tighten today, resulting in strong, gusty winds in the Mojave
Desert Slopes today. A Wind Advisory will likely be issued later
this morning for the Mojave Desert Slopes.
The trough of low pressure will deepen over Southern California
tonight. The probability of a trace or more of snow in Tehachapi
tonight is 52%. Right now, we are expecting an inch or less of
snow along Interstate 5 over Tejon Pass and along Highway 58 over
Tehachapi Pass tonight and Thursday morning. Be that as it may,
motorists should prepare for slick, icy roads and the possibility
of travel delays tonight and Thursday morning.
The trough of low pressure will move eastward into the Great Basin
Thursday afternoon. Temperatures may drop into the mid 30s in the
San Joaquin Valley Thursday night, leading to the possibility of
patchy frost. A fast-moving atmospheric disturbance embedded in
zonal flow aloft may impact the northern portion of the service
area this weekend. A stronger storm system may approach Central
California Tuesday.

.AVIATION...
IFR or lower conditions are possible in the northern portion of
the San Joaquin Valley early this morning due to fog. MVFR or
