    Though clouds thicken enough over Connecticut and western Massachusetts to bring some sprinkles and light rain showers by day's end into the evening, most of New England enjoys a fabulous day with temperatures climbing to around 80.

    The exception is the south-facing coasts and communities within about 40 miles of them, where cool ocean air is carried ashore on a southerly breeze.

    Eventually, the persistent south wind brings increasing humidity to New England, evidenced by increasing overnight clouds, scattered showers, areas of fog and a sticky feeling slowly increasing through the night.

    By Friday morning, the most humid air thus far this season will be setting up shop in New England, both south and north, with dew point temperatures climbing toward 70 degrees — a very humid feeling.

    The increased atmospheric moisture not only will be palpable but will aid in producing scattered showers with an embedded downpour in the morning, then scattered thunder later in the day and evening as highs climb to around 80 degrees with breaks of sun emerging from morning clouds and areas of fog.

    Although a cold front passes through New England Friday night, the humidity will linger Saturday for southern New England, at least early, and scattered showers or thunder will probably crop up for some while drier air moves into the northern half of New England.

    That drier air — though quite cool — will be in place Sunday while a large area of clouds, showers and cool temperatures seem likely to drift over the region for days starting Monday.

    Some brightening and warming returns by the end of the exclusive Early Warning Weather 10-day forecast.
