Minor afternoon breeziness can be expected today and Saturday before stronger winds from the southeast develop Sunday. More cloudiness can be expected as well on Sunday. Monday is expected to have lighter winds before breezes increase on Tuesday ahead of an approaching Pacific weather system.
Daily average Particulates are expected to remain in the Good range most days (close to Moderate Saturday). The exception will be Sunday with breezy to windy conditions from the southeast leading to pockets of blowing dust and in turn a daily average reading in the Moderate range (winds and dust actually start up late Saturday evening). If winds turn out to be stronger than forecast, Particulates will also be higher than forecast.
