Area Forecast Discussion
National Weather Service Sacramento CA
110 AM PDT Wed Sep 28 2022
Warm and dry weather conditions this week. Periods of locally
breezy winds, especially today.
Upper trough approaching the PacNW coast is spreading some high
clouds into NorCal early this morning, but overall skies remain
clear. Stratus is less extensive along the coast compared to the
past couple of mornings. Onshore gradients persist, though not
quite as strong as early Tuesday. Current temperatures are mostly
running around 3-6 degrees cooler compared to 24 hours ago and are
mainly in the 60s across the Central Valley.
Trough moves by to the north today and Thursday bringing a couple
of days of cooler temperatures. Additionally, breezy southwest
winds are expected today, especially in the Delta and across the
Ridging returns by the end of the week resulting in modest warming
as highs return to the lower 90s across portions of the Central
Valley. Some uncertainty on how the trough will evolve to our
east this weekend with implications on how much north/northeast
wind we`ll see over NorCal. We`ll continue to monitor.
.EXTENDED DISCUSSION (Sunday THROUGH Wednesday)...
Ensembles and clusters in good agreement with maintaining upper
ridge over NorCal through early next week. This will promote dry
weather with seasonally warm high temperatures from the mid 80`s
to low 90`s.
VFR conditions over interior NorCal for the next 24 hours.
Surface winds mainly below 12 kts except for up to 20 kts through
the Delta. Gusts up to 25 to 35 kts possible through the Delta and
over the mountains.
