    Sticky Tuesday Sun, Isolated Thunder for Some

    Tuesday: Sticky sun to isolated thunder. Highs in the 90s, heat index near 100 degrees.

    Overnight Tuesday: Sticky, mostly clear, chance thunder in Vermont. Lows around 70.

    Wednesday: Humid, scattered afternoon thunder. Highs near 90, heat index mid-90s.

    Our heat wave rolls on across New England Tuesday and, for some, it will even extend into Wednesday.

    The last couple of days haven’t brought strong atmospheric disturbances, but they’ve been strong enough to result in at least isolated thunderstorms. The problem in a setup like this is any storms that develop feed off the ample heat and humidity and can quickly become strong.

    We’ve seen this quick escalation in isolated storms the past few days and will see it again Tuesday, so keep an eye to the southern and southwestern sky. Watch the direction the storms will be coming from as they are expected to deliver locally drenching rain, lightning and the potential for gusty wind.

    Otherwise, the story continues to be the heat with temperatures shy of records, but reaching the lower to middle 90s with heat index values near 100 degrees during the afternoon.

    Hot and Sticky Day Thanks to Humidity

    [NECN] Hot and Sticky Day Thanks to Humidity

    Today (Tuesday): Sticky sun to isolated thunder. Highs in the 90s, heat index near 100°.
    Overnight Tuesday Night: Sticky, mostly clear, chance VT thunder. Lows around 70.
    Wednesday: Humid, scattered PM thunder. Highs near 90, heat index mid 90s.

    An approaching cold front Wednesday won’t arrive in time to keep temperatures from hitting 90 degrees in some communities. That will extend the heat wave. Meanwhile, others will fall just shy but humidity will continue and scattered storms will erupt during the afternoon and evening.

    Behind the storms, brand new, fresh air will be moving in Thursday and stay into the weekend, with the next chance of increased humidity and scattered thunder later Sunday, with temperatures in the 80s in our exclusive First Alert 10-Day Forecast.
