.KEY MESSAGES...

  - Dry with seasonable high temperatures through the next week.

  - Slight but uncertain chance for isolated thunderstorms on
    Monday.

.DISCUSSION...

Some high clouds visible moving across interior NorCal today on
GOES West Satellite imagery. Still, conditions remain dry with
seasonable temperatures. Valley highs primarily in the 90s today,
with 80s to 90s at higher elevations. Breezy onshore conditions,
though less windy today than the last few days.

The remainder of the week, upper level low pressure to the
northwest and high pressure to the east will continue the pattern
of periodically breezy onshore winds, with seasonable high
temperatures and cooler overnight lows. Early Monday morning there
is a less than 5% chance for an isolated thunderstorm to develop
over the western portion of the southern Sacramento Valley, though
there is very little confidence in this occuring. Monday afternoon
and evening, there is up to a 10% chance for isolated
thunderstorms along and east of the Sierra crest, including near
the Burney Basin.

.AVIATION...

VFR conditions continue through the TAF period, with FEW to SCT
clouds moving through the Sacramento sites this afternoon/evening.
Overnight another cloud deck shifts through Interior Northern
California bringing SCT clouds, with VFR ceilings. Winds during
the TAF period will be breezy at times near the Delta, but overall
around 5-10kts elsewhere.
