The sounding this evening samples an airmass a bit drier than
yesterday with PW at 1.34 inches. The temperature profile follows
the dry adiabat to 850 mb allowing drier air to mix through the
boundary layer down to the sfc. Winds are rather light and
variable to 650 mb then become westerly aloft. There are several
subtle subsidence inversions through mid levels.

Not much change in the forecast for the next few days. High
pressure is still in place and will remain in place over the next
few days. What that means for us is warm temperatures reaching
into the lower 90s over most of the area. Daily chances of showers
and thunderstorm will be the norm. Expect shower and storm
development to be limited to lake and sea breezes and any other
mesoscale boundaries. Will carry slight chance to chance pops for
most of the period. Overnight lows this week will generally be in
the low 70s to upper 60s. A cold front looks to move into the area
later on in the week. This will increase rain chances greatly in
the latter half of the week into next weekend. Temperatures will
cool some going into next weekend with that boundary in the area
and the greater coverage of showers and storms expected. 13/MH
VFR Conditions are expected to prevail with the exception being
possibility of patchy late night/early morning fog at KMCB and
KHUM. Isolated SHRA/few TSRA may briefly impact a couple airports
near the coast and tidal lakes this afternoon, however only
included mention of VCTS at KHUM where satellite imagery indicates
building cumulus clouds.
High pressure will continue to be the main player over the
coastal waters. With the core of the high closer to the area,
winds will be lighter than they have been for the last few days.
Variable winds of generally less than 10 knots will persist
through at least mid week. Seas will be 2 feet or less.
