    Records fell in parts of New England over the weekend. St. Johnsbury, Vermont hit 85, breaking the record of 85 set "way back" in 2015. Meantime, highs soared to 90 in Lawrence, Massachusetts and near 90 in Metrowest.

    While 80s may be more common these days in September, we're really pushing the limits of the heat these days. Today we'll stumble a bit as the numbers come down thanks to a few more clouds and a steady south wind. That said, it will still feel like a summer day.

    A flash flood watch was issued for northern Connecticut, Massachusetts and Rhode Island that will be in effect Monday through late Tuesday.

    In Connecticut, Hartford, Tolland and Windham are under the watch. In Massachusettes, Essex, Franklin, Hampden, Hampshire, Middlesex Norfolk, Northern Bristol, Northern Plymouth, Suffolk and Worcester counties are affected by the watch. As for Rhode Island, Kent and Providence are under the watch.

    What remains of Florence - and it's a lot - is still spinning in Western North Carolina and Tennessee. Plumes of tropical rain are feeding into the circulation. A good amount of this will disperse/decay with time in the next 24 hours, but since the storm is getting scooped up by a fast-moving jet stream, the rain will be on our doorstep by tomorrow morning.

    Latest forecasts keep at least some of the heavy rain intact as the storm crosses the Commonwealth. Expect the most intense and persistent downpours to target Northern Massachusetts and Southern New Hampshire on Tuesday afternoon.

    It's here that brief, localized flooding could become a problem into the evening drive. Stream rises will be abrupt, so watch out for rising water. Elsewhere, pockets of heavy rain could pass as well, but the primary focus for two hours of rain seems to lie to the north of Boston.

    A very sticky wind will blow in with the storm system, too. Dew points will rise near or over 70, making it super-humid, as the winds gust from the southwest. And then, just as quickly as it arrived, it will move away Tuesday night.

    In its wake are cooler temps and a ton of clouds. We’ll be a little closer to normal, but heat may make a cameo by the end of the week.
