223 PM PDT Wed Jun 29 2022

Decreasing high temperatures expected through Sunday, with below
normal temperatures for the holiday weekend. There will be a
slight warm up next week. Locally breezy onshore winds in the
afternoons and evenings continue into next week.


An upper level trough is bringing onshore flow with cooler
temperatures today, and this pattern is expected to continue into
next week. This will also bring breezy southwesterly winds in the
afternoon and evening. Humidity levels will gradually increase
into the weekend, which will bring decreasing fire weather

Temperatures this afternoon are 5-11 degrees cooler than
yesterday. This has brought the heat risk back to low levels
across much of area this afternoon. Breezy onshore winds continue
today, especially over the Sierra crest where gusts are being
observed up to 23-37 mph this afternoon.

Troughing remains off the coast through late week but begins to
deepen Friday into the weekend bringing further cooling to the
area and the potential for precipitation Sunday. By Saturday,
widespread highs in the 80s are expected throughout the Valley,
with mountain locations generally in the 60s. EFI highlights
breezy Delta winds on Saturday with gusts to 30-35 mph. Much of
Solano County should remain in the 70s on Saturday.

A chance of light showers moves into the mountains of northern
Shasta County by late Saturday afternoon and early evening as this
system begins to move onshore.

Clusters continue in good agreement that a trough will continue
to impact interior Northern California Sunday into early next
week. The coolest day is expected on Sunday with EFI highlighting
not only the cool high temperatures across the area, but also
breezy winds in the Delta. Highs will generally be around 10-15
degrees below normal for the date. This system also brings a
chance for some light rain showers on Sunday and Monday, mainly
for the mountains of Shasta County. Increased cloud cover can be
expected elsewhere. The potential for thunderstorms should remain
north of the area over Siskiyou County.

Independence day looks cool across the area, a few degrees warmer
than Sunday, with temperatures 10 to 15 degrees below normal. For
the Valley this means low to mid 80s. Dry weather and a slight
warming are expected by the middle of next week.

VFR conditions next 24 hours. Winds generally under 10 kts in the
Valley with gusts 15-20 kts possible for the Delta, Sacramento
Metro, and northern San Joaquin Valley through 06 UTC. Gusts 20-35
kts also possible over the Sierra through 06 UTC. &&
