Area Forecast Discussion
National Weather Service Sacramento CA
333 AM PST Fri Feb 8 2019

.SYNOPSIS...
Cold and showery pattern returns with several weather systems
forecast to bring low-elevation snow to the region into next week.
Check ahead before planning travel into the foothills and
mountains.

&&

.DISCUSSION...
Partly to mostly cloudy skies cover the region early this morning
as satellite imagery shows the cold upper low (and its bands of
associated showers) off the northwest coast of California
centered along 130W just to the south of 40N. Current temperatures
are milder compared to 24 hours ago due to the cloud cover and
range from the single digits in the mountain valleys to the mid
30s to mid 40s across the Central Valley.

Several cold systems are forecast to affect the region into early
next week. This first disturbance and associated frontal band
pivots through central California tonight bringing increased
precipitation out ahead of it by late this afternoon or early this
evening. Snow levels remain fairly low, so accumulating snowfall
likely again for the Coastal Range and foothills. Highest POP/QPF
will be across the southern half of the forecast area with lighter
amounts over the northern mountains and northern Sacramento
Valley.

The break between the first system and a second stronger system
will be very brief, and likely not noticeable for many areas. A
brief break in showers will be possible Saturday morning before
the next round of showers drops south with the cold front Saturday
afternoon.

Another break will be possible later Sunday and Sunday night
before a third system spreads precipitation back into the region
early next week.

Although winter impacts are likely over the mountains this
weekend due to moderate snowfall, the colder and drier source
region of these weather systems will limit moisture and Valley
rainfall. Therefore flood or debris flow impacts are not expected
at the lower elevations. Best chance for a little snow across the
northern Sacramento Valley will be Sunday.

&&

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)
Active pattern is expected by mid-late next week given persistent
troughing pattern. However, storm strength and timing differences
are still evident leading to low confidence in specific details.
Guidance suggests a strong system diving southward around the
middle of next week that could have a chance to tap some Pacific
moisture, and bring widespread precipitation across the region. At
this point, the GFS is the most aggressive solution. In addition,
the GFS and EC disagree with how quickly to eject this system
eastward, with the ECMWF being much more progressive than the GFS.
Additional waves of precipitation could be possible late in the
week, potentially through next weekend.

&&

.AVIATION...
Precipitation will gradually move in from the west this afternoon
into the evening hours with lowering visibilities/ceilings
leading to MVFR, locally IFR, conditions. Wind gusts up 15-20 kts
possible from KSCK southward mainly after 02Z Saturday.

&&

.STO WATCHES/WARNINGS/ADVISORIES...
Winter Storm Warning from 4 PM this afternoon to 4 AM PST Monday
for Burney Basin / Eastern Shasta County-Clear Lake/Southern
Lake County-Motherlode-Mountains Southwestern Shasta County to
Northern Lake County-Northeast Foothills/Sacramento Valley-
