Area Forecast Discussion
National Weather Service Sacramento CA
925 AM PDT Sat Apr 14 2018

.SYNOPSIS...
Dry and warmer weather today, then Pacific storm moves through
Sunday and Monday with rain, mountain snow, and gusty wind.
Dry Tuesday then possible unsettled weather Wednesday and
Thursday.

&&

.DISCUSSION (Today through Tuesday)...
Upper ridging will result in dry and warmer weather today with
above normal temperatures. Highs forecast in the mid to upper 70s
for the Central Valley with upper 50s to lower 70s for the
mountains and foothills.

Higher clouds spread over the forecast area this evening as
heights lower and Pacific frontal system approaches. Models begin
spreading frontal precip across far NW portions of the CWA Sunday
morning. Pressure gradients also increase over Interior NorCal
at that time, ahead of approaching baroclinic zone. Model precip
spreads to about I-80 by 00z Monday. Winds increase in the Central
Valley with guidance suggesting potential for wind advisory
speeds generally from around Oroville northward Sunday afternoon.
Precip turns showery in the Central Valley after 00z Mon as
heavier precip spreads into the Western Plumas mountains and
Sierra Nevada. Snow levels Sunday evening initially start out
around 4500 to 6500 feet.

Precip decreases in the Western Plumas mountains aft 06z Mon and
in the Sierra after 12z. Snow levels Monday morning expected to be
around 3000 feet. Showers continue Monday with best chances in
the Central Valley during the afternoon. Models also showing
increased instability during this time as cold upper trough moves
through. Potential for thunderstorms exist Monday in the Central
Valley and foothills. Shear profiles suggest potential for isolated
rotating storms but more unidirectional and thus main threat appears
to be small hail with colder mid level air moving through. Precip
winds down Monday evening with drier weather Tuesday. Attm storm
total QPF looks to be up to around half an inch in the Central
Valley, locally higher with stronger convective storms. Liquid
totals in the foothills and mountains of up to around 1.25 inches
are forecast, with snow totals of 6 to 12 inches above 5000 feet.

PCH

&&

.EXTENDED DISCUSSION (Wednesday THROUGH Saturday)
Uncertainty continues next week in how quickly the cold closed
low will move onshore the West Coast. Appears main shower chances
will be Wednesday and Thursday with gradually drier and milder
weather late in the week. This is not expected to be a
particularly cold or wet system with less than a quarter inch of
QPF and only a few inches of snow possible above 4500-5000 feet.

&&

.AVIATION...
VFR conditions next 24 hours. Local south wind gusts 15-20 mph
northern Sacramento Valley 22Z-02Z Sunday.

&&

.STO WATCHES/WARNINGS/ADVISORIES...
None.
