.SYNOPSIS...
High pressure results in above average temperatures across
interior NorCal this week.

&&

.DISCUSSION...
Little change in the overall pattern expected for interior NorCal
the next couple of days as the region will remain between strong
high pressure over the Desert Southwest and a low dropping
southward along the BC coast. Temperatures will likely warm a few
more degrees today compared to Monday, and then hold pretty
steady for Wednesday.

Lowering heights aloft will occur over NorCal later Wednesday
into Friday as the low moves across the PacNW. This will only
result in modest cooling for the region late in the week as the
Delta Breeze kicks up a notch and the overall airmass cools
slightly. Highs Thursday and Friday are expected to top out in
the mid 90s across the Central Valley.

&&
.EXTENDED DISCUSSION (SATURDAY THROUGH TUESDAY)...
From Saturday into early next week, high pressure over the
southwestern US and into the Eastern Pacific Ocean will dominate
the weather pattern as it builds into NorCal. Expect dry
conditions with temperatures ranging 5 to 12 degrees above normal
during the extended period. Valley highs will be in the upper 90s
to low 100s, Delta in the 80s to mid 90s, Foothills in the upper
80s to upper 90s, Mountains in the 70s to upper 80s.

&&

.AVIATION...
Southwesterly flow over the Sierra, otherwise, light winds less
than 10 kts in the valley at TAF sites. VFR conditions continue
across interior NorCal.

&&

.STO Watches/Warnings/Advisories...None.
