Area Forecast Discussion
National Weather Service Sacramento CA
1025 AM PST Sun Feb 3 2019

.SYNOPSIS...
Series of Pacific storms will impact Northern California through
Tuesday. Periods of moderate to heavy precipitation with gusty
wind and isolated thunderstorms are expected. Drier weather
returns by midweek.

&&

.DISCUSSION...
Morning Update: Norcal in between systems this morning, but upslope
precip continues over the Sierra, and showers in the Valley mainly
just N and S of the I-80 corridor as moist SW flow continues over
the region and in advance of the short wave that is approaching the
CA coast. This feature is forecast to move just N of the Bay area by
00z Mon, bringing another area of showers with it. Forecast
soundings from over the Srn Sac Vly/Nrn San Jqn Vly still show some
surface-based convection possible this afternoon, and with cellular
cloudiness developing over this already, there is still the
potential for thunder in this area.

Large scale ascent will be increasing tonite as the aforementioned
wx system moves through the area and the larger scale trof deepens
off the coast. BUFKIT forecasts heavy precip over BLU where hourly
snowfall rates of 2-3 inches/hr are forecast from after midnight to
about noon Mon. This is the time frame where omega and shear line up
within the dendritic (snow) growth zone. Studies/research indicate
high hourly snowfall rates occur and result in whiteout conditions.
We are contemplating upgrading the WSW to a Blizzard Warning to
account for perilous travel over the Sierra during this time.  JHM

.Previous Warning...
Upper low weakening to trough as it tracks across Central CA this
morning. Widespread showers overnight producing mostly light to
moderate precipitation. System has increased wind from around the
Sacramento area southward as it moved onshore. Guidance suggesting
strongest wind is occurring now and speeds will trend down through
the morning hours. Showers will continue this morning, becoming more
widespread again this afternoon as instability increases and next
short wave trough moves inland. Best CAPE, to around 300 J/kg,
depicted from about the Central Sac Valley southward this afternoon
for potential isolated thunderstorm development. Snow levels progged
to be around 4000 to 5000 feet today.

Another short wave trough follows inland tonight into early
Monday bringing additional showers and colder air into interior
NorCal. Snow levels overnight lower to around 3000 to 4000 feet.
Wave followed quickly by a colder and much deeper system digging
south from B.C. along the West Coast. This will result in
additional precipitation with heavy snow in the mountains. Snow
ratios increase to 15 to 1 or more as snow levels lower into the
foothills Monday. Significant snow possible in the foothills with
additional 5 feet or more possible in the Sierra Nevada.
Steepening lapse rates Monday could lead to thunderstorm
development in the Central Valley. With 5h temps lowering into the
lower -30s Deg C, stronger storms likely to produce some hail.

Upper low and associated cold pool tracks inland over NorCal
early Tuesday, then into the Great Basin in the afternoon. -6 Deg
C at 850 Tuesday morning supports some rain/snow mix, if showers
occur, in the Northern Sac Valley to around the 500 ft elevation.
Showers become more widely scattered during the day Tuesday as
main dynamics shift east of the CWA. High temps Tuesday expected
to be upwards of 10 to 20 degrees below normal with upper 40s to
around 50 in the Central Valley and 20s to low 40s for the
mountains and foothills.

Showers end by Tuesday night as subsidence increases and drier
northerly flow aloft sets up over interior NorCal. Upper ridging
begins to build back inland on Wednesday with continued below
normal temperatures.
