.DISCUSSION...

Persistent pattern through Saturday with the earliest chance of rain
moving in Saturday night into Sunday. Breezy northerly winds during
the daytime hours up to 15 mph with an occasional gust to 20 mph looks
to keep drier conditions with minimum RH around 20 to 30% near the site
through the day on Friday. Overnight winds are expected to relax and
shift westerly, bringing in weak moisture and improving RH to around
60 to 70%. Saturday shifts winds westerly, improving minimum RH to
near 40%.

Highest uncertainty is Friday, where westerly winds 10 mph between
10 am and noon may overtake northerly winds. This scenario will
improve RH to around 30 to 40%.
