Area Forecast Discussion
National Weather Service Sacramento CA
338 PM PDT Mon Mar 20 2023

.SYNOPSIS...
Showers return late tonight and continue through Wednesday, heaviest
Tuesday, with afternoon thunderstorms possible. Accumulating
snowfall is expected above 4000 feet. There will be some gusty
southerly winds on Tuesday. The cool and unsettled weather pattern
will continue through mid to late week, with periods of showers.
The weekend will see some cold morning temperatures.

&&

.Discussion...
Short-wave ridging has brought a break in precipitation to the
region today and tonight. There were some lingering showers
earlier this morning, mainly over the Sierra and the northeast
foothills. This afternoon there are just some scattered clouds
clouds left over the area. The Winter Storm Warning was allowed to
expire at 11 am PDT.

The next storm system arrives late tonight and continues into
Wednesday. This will be a cold closed low pressure system from the
Gulf of Alaska which will move southward along the California
coast and then move inland over Southern California. The
trajectory of this system will bring the greatest moisture into
central and Southern California. This system will bring lower snow
levels than in recent storms, around 3000-5000 feet. The heaviest
amounts for northern interior California will be in the Sierra
south of US Highway 50, where 1 to 2 feet of snow is possible
above 6000 feet. A Winter Weather Advisory is in effect 5 am PDT
Tuesday to 5 am PDT Wednesday, with delays in travel likely at
times. Gusts to 50 mph are possible and along with the snow could
bring some reduction in visibility at times.

Some breezy southeasterly winds are possible Tuesday, gusting up to
25-35 mph over the northern San Joaquin Valley, lighter to the
north.

Highest forecast rainfall amounts through Wednesday are
0.75"-1.00" for the Delta and locations in the Valley from
Sacramento southward. Isolated thunderstorms are possible Tuesday
afternoon and evening for the northern San Joaquin and southern
Sacramento Valleys. Instability is not especially strong but
there is a fair amount of shear. Small hail and heavy rain are the
main threats with any thunderstorms that form.

Some residual showers will linger into Thursday on the backside of
the system, especially over the mountains. A weak system brushing
by to the north could bring more light mountain showers on Friday.

.EXTENDED DISCUSSION (Friday THROUGH Monday)...
Ensembles show longwave troughing continues off the West Coast
through the extended forecast period with series of shortwaves
moving through. This will keep unsettled weather Friday through
Monday with showers and foothill/mountain snow showers. Below
normal high temperatures expected, with some cold morning lows.
The NBM projects Valley lows in the mid to low 30s, potentially
around freezing for the northern Sacramento Valley Sunday morning.
Clusters show good agreement in a stronger low early next week,
but timing and location differences are bringing uncertainty, so
it remains unclear how impactful this system will be. Stay tuned!
