Clouds and a few showers this morning, partly sunny skies are expected for later today, but you'll definitely notice the humidity. There could be a random, spotty shower at just about any point, but much of the day will stay dry. High temperatures will reach the 80s. If you're heading to the beaches, watch out for rip currents along the South Shore and swim near a lifeguard.
