FRIDAY EVENING AND OVERNIGHT

A stray passing rain shower is possible, but most of the evening is dry, warm and muggy. Overnight, it will be partly cloudy to mostly clear, with lows in the upper 60s to low 70s into early Saturday morning.

WEEKEND OUTLOOK

Saturday will be the better weekend day. There will be a mix of sun and clouds, with temperatures in the mid-80s, and it will still be humid. It will be dry and decent, but with times of more clouds than sunshine.

Sunday is mostly cloudy. There is the chance for a spotty rain shower in the afternoon and evening, but most of the day is dry until late Sunday night. High temperatures will be in the low 80s and you will still feel the high humidity.

MARINE CONDITIONS

Other than a moderate risk for rip currents at the South Shore beaches, there are no posted advisories for boaters for Saturday.
