.DISCUSSION...
Expect an increase in dewpoints today as we transition into the
warm sector. RH values will still drop into the upper 30s, though,
during the afternoon hours. Southward facing hills could get better
warming from more sun exposure, dropping the RH by a couple of
notches from the forecast. Southwesterly surface winds will increase
10 to 15 mph with gusts 20 to 25 mp through this afternoon. The
nocturnal inversion tonight will allow winds to subside except on
exposed hill tops. Dewpoints and temperatures increase slightly
for Saturday resulting in slightly higher RH values.
