.DISCUSSION...

...Today through Saturday...
Current GOES-West visible satellite imagery illustrates widespread
cloud cover across much of interior northern California on this
late Spring Friday morning as the system that has impacted the
area over the past few days begins to taper off and exit the
region. Some lingering showers will be possible over the mountains
today but drier conditions are forecast elsewhere. High temperatures
will still be below normal today, in the 70s in the Valley, 60s
to 70s in the foothills, and 40s to 60s in the mountains.
Temperatures will gradually warm over the weekend and into next
week. Saturday`s forecast highs will trend around 5 to 10 degrees
warmer than today, in the 80s in the Valley, 70s in the foothills
and 50s to 60s in the mountains. Another wave will bring a slight
chance for showers and thunderstorms on Saturday, to the
mountainous areas north of Interstate 80, including portions of
the Coast Range, Shasta County and southern Cascades. Dry
conditions are expected elsewhere.

...Sunday and onward...
Locally breezy northerly flow will develop behind this wave on
Sunday, bringing gusts of 15 to 20 mph in the Valley and Delta.
This will bring along some drying with lower humidity and warmer
temperatures. As we head into the first week of June, weak ridging
will bring a gradual warming trend to the area. Areas of Moderate
HeatRisk return to the Valley next week. The Delta vicinity will
see some late day and overnight relief/cooling as an increased
onshore flow gradient will bring periods of breezy west to
southwest flow, keeping those areas mainly in Minor HeatRisk.
Drier conditions and lower daytime humidity are also forecast,
down to the mid teens to mid 20s in the Valley especially early
to mid week. Towards the end of the week, ensembles are showing an
upper level trough dropping down and moving across the Pacific
Northwest into next weekend. While there is still some uncertainty
with this, it does look like a cooling trend is then favored for
the latter half of next week into the following weekend. Be sure
to stay up to date with the latest forecasts at weather.gov!

.AVIATION...
Mostly VFR conditions over the next 24 hours except lingering low
ceilings and isolated mountain showers will bring local MVFR and
IFR conditions. Sustained surface winds generally less than 12 kts
in the Valley, except the Delta with southwest gusts to 20-25
kts. 10-15% chance for isolated thunderstorms over the southern
Cascades and Shasta County mountains after 18Z Saturday.
