Area Forecast Discussion
National Weather Service Sacramento CA
1235 PM PDT Sun Oct 1 2023
.Synopsis...
Lingering showers over the Sierra today, otherwise dry and milder
weather returns this week. Occasional breezy north winds.
&&
.Discussion...
Shower activity has quieted this afternoon with sites clearing
across the valley outside of some lingering clouds near
Sacramento. Today’s rain will be primarily limited to south of
Hwy. 50 with a slight chance of thunderstorms (10-15%
probability). Totals will be under a tenth outside of any
convective showers forming that may have brief periods of heavier
rain. High pressure in the Pacific slides eastward and extends
ridging through the area by Monday night. This will be the main
weather driver through the short term resulting in northerly flow
and rising temperatures across our forecast area.
Gusty northerly winds across the Northern Sacramento Valley and
west of I-5 from around 15 to 25 mph started this morning and
should persist through the early afternoon before gradually
tapering off through Monday morning. This week will see several
periods of northerly-northeasterly winds 5 to 15 mph with a
stronger period of winds Tuesday afternoon through Wednesday
afternoon. EC Ensemble data shows the strongest winds occurring
Tuesday late afternoon through Wednesday morning with gusts 25 to
35 MPH. NBM guidance has trended to increased confidence of gusts
occurring with around 30-60% probability of gusts exceeding 30 MPH
early Wednesday morning.
With the increased temperatures and northerly flow, conditions are
set to dry, particularly in areas of northerly winds through the
week. Afternoon humidity values remain in the upper teens and low
20s this week, so critical fire weather conditions aren’t expected
but will continue to be monitored as we get closer to midweek.
Temperatures will trend warmer this week and can expect a 4-7
degree increase Monday and Tuesday before settling into upper 80s
and low 90s across the Valley in the latter portions of this week.
&&
.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...
As the ridge continues to expand over NorCal, temperatures will
increase into the weekend, topping off around Saturday. Dry
conditions are expected and high temperatures in the Valley will top
out in the high 80s to low 90s. Over the weekend, the ridge will
begin to move east, putting NorCal in between the ridge to the east
and a trough to the west, causing onshore flow and bringing the area
back to seasonable conditions. //SP
&&
.AVIATION...
VFR conditions are expected over most of the area for the next 24
hours, with exceptions over the mountains, where isolated
thunderstorms may cause MVFR/IFR conditions until 03z Monday. Winds
in the Sacramento Valley will be northerly, with sustained speeds up
to 20 kts and gusts up to 25 kts until around 00z Monday. Otherwise,
surface winds will mostly remain below 12 kts.

.STO WATCHES/WARNINGS/ADVISORIES...
None.
