Area Forecast Discussion
National Weather Service Sacramento CA
330 AM PDT Mon Jun 14 2021

.SYNOPSIS...
Seasonably warm weather early this week. Hot conditions with high
to very high heat risk expected for the second half of the week.
&&

.DISCUSSION...
Persistent upper trough that has remained off the West Coast all
weekend remains nearly stationary with a front and associated
showers remaining over northwest California. Skies are mostly
clear except for some areas of clouds over the northern mountains.
Southerly breezes are beginning to pick up again across the
northern half of the Sacramento Valley as slight pressure falls
occur to the northwest and north of the region. Southerly gusts
in the teens to around 30 mph north of Willows and Oroville.

Another short-wave will lift northeast across far northern
California later today bringing a renewed chance of showers across
Shasta County, but precipitation amounts will be very light
(generally under a tenth of an inch). Breezy conditions will
become more widespread by afternoon as surface pressure gradients
tighten. Highs today will be in the 80s across the Central Valley,
around 5-10 degrees cooler compared to Sunday.

Warming returns Tuesday as the trough finally lifts out to the
northeast as high pressure centered over the Southwest expands
westward. Highs will return to the lower 90s across most of the
lower elevations and surface winds will transition from onshore to
light northerly.

Heat cranks up Wednesday with highs expected to exceed triple
digits across the Central Valley, then record breaking heat
forecast to begin Thursday as most valley highs will range from
105-110 degrees. Overnight lows will also be very mild, ranging
from the upper 60s to around 80 across most of the valley, and
foothill and mountain thermal belts.

&&

.EXTENDED DISCUSSION (Friday THROUGH Monday)...
High pressure over the Desert SW will continue near record to
record heat over interior Northern California Friday. Ridge
gradually weakens through the weekend into early next week. This
will result in a slow downward trend in high temperatures with 90s
returning to Delta breeze influenced areas Sunday. Highs in the
90s become more widespread in the Central Valley Monday with
triple digit heat lingering in portions of the Northern Sacramento
Valley.
