Area Forecast Discussion
National Weather Service Sacramento CA
726 PM PDT Sat Oct 1 2022

Warm and dry conditions continue into next week with temperatures
slightly above normal for this time of year.

.UPDATE DISCUSSION... Delta Breeze is cooling things off quickly
this evening. This has influenced a few high temperatures, which
reached 90 at Sacramento International Airport, but only 83 at
Sacramento Executive Airport and 88 for downtown Sacramento. At 7 pm
it was only 64 at Fairfield, a drop of 17 degrees compared to this
time yesterday. Winds there were 26 mph gusting to 33 mph out of the
southwest. Updated forecast with Delta winds using Lamp guidance to
reflect observed and expected winds tonight into Sunday.

Sunday morning lows for influenced areas are on track to
drop into the 50s. Fort Ord Profiler shows marine layer thickening
to around 3000 feet, which could allow for a stratus intrusion
through the Delta into the Sacramento metro area. Introduced
scattered clouds into TAFs, with latest HREF showing some low
stratus clouds possible into the area. May need to introduce some
TEMPO broken ceilings in 06Z TAF forecasts.

High pressure will build over the west coast the next several
days with some warming occurring during the first part of next
week. Temperatures will peak over the region the middle of next
week. Warm and dry conditions are forecast through the period.
After Sunday, valley high temperatures will be in the upper 80`s
to mid 90`s through the period about 5 to 10 degrees above normal.
Low temperatures will cool into the mid and upper 50`s through
the period. Winds will remain less than 15 mph.

Cluster analysis and ensembles remain in very good agreement with
ridging continuing over interior northern California most of next
week with warm and dry weather conditions prevailing. A slight
flattening of the ridge late next week into next weekend will
allow for some slight cooling to occur.



General VFR conditions are forecast to prevail throughout interior
northern California over the next 24 hours, though SCT/BKN ceilings
from marine stratus clouds are possible 12-18z for the Delta and
Sacramento metro airports. Surface winds at/below 12 knots through
the period, except near the Strait of Carquinez, where winds to 25
kts with gusts to 35 kts are possible through the day Sunday.
