be accompanied by a subtle drying trend, with min RH dropping to
15-25% across interior mountains this weekend. Onshore winds will
remain moderate and diurnally driven through the week. As monsoon
moisture filters out, the chance for thunderstorms has dropped to
zero.
Note : All winds are 20-foot Winds Unless otherwise specified.
