Synopsis...dry weather can be expected over the central
California interior for the next several days. Temperatures
will average slightly cooler than normal through Monday.
A warming trend can be expected for the remainder of the
week with temperatures ending up several degrees above normal
Discussion...ocean-cooled air continues to flow through the
passes along the west side of the sj valley. Local gusts are
currently around 30 mph in these areas, including at Pacheco Pass
and in Sunflower Valley in far southern Kings County along Highway
41. Expect breezy conditions to continue at these locations through
this evening, and winds could briefly pick up this evening once
again in other parts of the sj valley. Temperatures are several
degrees cooler compared to this time yesterday, especially in the
Central Valley, quite a change compared to the last couple of
Cooler than average to seasonal temperatures will likely continue
on Monday and Tuesday as the west-southwest flow aloft prevails,
though daytime highs will trend slightly warmer each day. Highs
will remain mainly in the 90s in the warmest locations, except for
some triple digits in the Kern County desert. Dry conditions are
expected to continue for the next several days.
High pressure returns to the region on Wednesday through the end
of the week, so temperatures will once again rise back to above
average. Widespread triple digits will return and likely last
until next weekend. Models continue to show a tropical system off
the coast of Baja California, though not at as strong compared to
yesterday's runs. Confidence is decreasing for this period,
including with regard to impacts from this tropical system and
the high pressure ridge persisting and possibly strengthening over
much of the southwest U.S. And much of California.
VFR conditions can be expected over the central California
interior during the next 24 hours.
