    Weather Forecast: Hot With Possible Thunderstorms

    Friday night: Mild and muggy. Low 70s. Steady southerly breeze. Saturday: Hot, breezy and very humid. Thunderstorms possible in the afternoon. Upper 80s to low 90s. Sunday: Dramatically less humid. Sun & clouds. Cooler. Mid-70s at the coast, to near 80 elsewhere.

    (Published Saturday, July 6, 2019)

    It’s an official heat wave in parts of New England, with some cities and towns hitting 90 or higher for the third consecutive day. Humidity is creeping up today, particularly along the south coast where some fog is flirting with the coast.

    Overnight the fog will expand as the humidity increases for all of us. With lows in the 70s it will be very uncomfortable for sleeping without the benefit of air conditioning.

    Morning fog will linger on the Cape and Islands in particular, and it will dance with that part of the region throughout the day. However, most of the day on the Cape and Islands will be dry Saturday.

    Elsewhere expect highs in the 80s with very high humidity and scattered storms.

    The storms will develop first around lunchtime in far northern and western New England, and then they’ll slide into southern New England during the mid to late afternoon and especially the evening.

    Expect heavy rain, lightning, and gusty winds with the storms that develop, but it’s important to remember it will not at all be a washout.

    A whole new airmass arrives after the storms, with sunny and less humid weather on Sunday. Expect highs in the 70s to around 80.

    That same beautiful weather continues into the middle of next week as temperatures slowly tick up, back above average. Storms will creep back next Thursday and Friday, as well.
