...Strong Winds over Interior Northern California...

.Strong north to east winds are forecast over interior northern
California beginning late Sunday night and lasting into Tuesday
evening. The winds are expected to be strong enough to damage
trees and cause power outages. The strongest winds are still expected
to be Monday night and Tuesday over most of the area.

The strong winds are the result of the difference in pressure
between a strong low pressure system moving over the area on
Monday and strong high pressure building in behind it Monday
night and Tuesday.

Area Forecast Discussion
National Weather Service Sacramento CA
229 AM PST Fri Jan 15 2021

.SYNOPSIS...
Dry weather into next week with areas of late night and morning
valley fog. Well above average temperatures will continue into
next week. Strong winds possible early next week.

&&

.DISCUSSION...
Infrared satellite imagery reveals developing Tule Fog in the
Central Valley this early Friday morning. Visibilities are already
down to a quarter-mile at several airports. Consequently, a Dense
Fog Advisory is in effect for the southern Sacramento Valley, the
Delta, as well as the northern San Joaquin Valley through 11 AM
PST Friday.

A broad upper level ridge parked about 400 miles west of Santa
Barbara will promote another afternoon with temperatures well-
above January normals. Most communities in the Sacramento Valley
will max out in the 60s. Similar to yesterday, localized areas
with lingering fog into the afternoon hours may struggle to get
out of the upper 50s. For reference, normal high temperature for
January 15 at Downtown Sacramento is 54 deg F and 55 deg F at
Redding.

The offshore ridge is forecast to amplify over the weekend,
leading to further warming across much of the Golden State.
Unfortunately, this also means that dry conditions are forecast to
prevail as we dive deeper into what is ordinarily the wettest
time of the year.

A shortwave will ripple around the outer periphery of the upper
level ridge late Sunday and into Monday, quickly diving south from
the Pacific Northwest into California. A second piece of energy
will drop south on Tuesday as an inside slider, reinforcing
northeasterly, and potentially strong/damaging offshore flow. More
on that in the extended discussion section... // Rowe

&&

.EXTENDED DISCUSSION (Tuesday THROUGH Friday)...
A closed off upper level low will be set up over SoCal with a
strong Pacific high begining to build into NorCal. This will bring
a strong pressure gradient over the region with strong north to
east winds late Sunday night into Tuesday. NAEFS shows a band of
anomalous winds (30+ year return intervals) for the wind
component. Current forecast indicates wind gusts ranging from the
30 to 40 mph in the Valley and into the Delta, locally higher.
There is the potential for higher wind gusts up to 70+ in favored
gaps, canyons and ridgetops. Weakened or burned trees and limbs
may fall in strong winds. Stay tuned for details.

Dry weather is expected for much of the extended period as we sit
on the eastern edge of the Pacific high. The ridge will push west
late in the week as a short wave trough digs down the coast. This
may bring some light showers to the area. NBM guidance shows
daytime temperatures gradually cooling down through the period,
but highs could still remain above normal for mid January.

&&

.AVIATION...
Areas of IFR/LIFR from KMYV south due to fog and low cigs this
morning. Conditions improve after 18z with VFR conditions expected
by 20z. VFR conditions north of KMYV. Winds remain under 10
knots.

&&

.STO WATCHES/WARNINGS/ADVISORIES...
Dense Fog Advisory until 11 AM PST this morning for Carquinez
Strait and Delta-Central Sacramento Valley-Northern San Joaquin
Valley-Southern Sacramento Valley.
