    One last day of summer sun and warmth will deliver record high temperatures to parts of Northern New England before the remnant moisture of Florence arrives with torrential rain on Tuesday.

    Monday’s sunshine couples with a southwest wind to bring summer redux once more, though increasing clouds in the afternoon and evening portend the changes ahead, formed by moisture riding well ahead of Florence’s remnant rainfall.

    Rain will start after midnight Monday, expanding during the morning commute, avoiding southeast Massachusetts most of the morning and midday and never quite reaching the North Country at all.

    For the rest of us, showers will turn to downpours, then downpours will turn to rain and embedded thunder as the day progresses. Those showers will drop exceptional rainfall rates that will produce localized flooding of streets and urban flooding. It will particularly make an impact during the afternoon as rainfall totals of two to four inches with locally higher amounts are expected.

    As rumbles of thunder move through, one or two thunderstorms may even turn damaging, as isolated tornadoes continue to develop in the remnant of Florence.

    By Tuesday night, rain will be departing, but a cool, moist flow of raw fall air will move in for Wednesday, locking in gray skies and chilly temperatures that will struggle to get much past 60 degrees.

    Thursday should bring a return of some sun in a crisp air, with Thursday night showers marking the return of warmth by Friday.

    Right now, the weekend looks split with Saturday looking good, and Sunday not necessarily a washout, but quite possibly bringing some showers. High temperatures should drop to the 60s from Sunday into early next week in our exclusive Early Warning Weather 10-day forecast.
