 Flash flooding, certainly a concern. Temperatures in the upper 60s overnight. A couple of showers to start tomorrow morning, then sunshine breaks out. Less humid in the afternoon. Pretty nice day, 83 for the high temperature. Tomorrow night, mainly clear. Temperatures in the 60-degree range in Boston, 50s in the suburbs. And then Friday, a pleasant day. Mostly sunny, low humidity, 75 at the harbor, 80 inland. A little more humidity Saturday. We may pick up a shower late in the day.
