    After the rain from Michael, we say goodbye to summer

    As the remnants of what was once Hurricane Michael make their way north, the primary effect for New Englanders is going to be rain. After that, it’s time to say goodbye to the summer pattern we’ve seen over the last several months.

    The rain from Michael, now a tropical storm, will move into Southeastern New England, especially Nantucket and Martha’s Vineyard, on Friday morning. Winds will also be noticeable over Cape Cod and the Islands.

    There is a flood watch in effect later Thursday through the evening hours. The highest likelihood of any flooding is going to be south of Boston, although there can always be temporary street flooding from some of the downpours as we head into the evening. Around Boston, this watch is related to a cold front more than Michael’s rainfall, but Southeastern Mass. will feel the effects of both the cold front and the tropical system.

    A flood watch is posted for southern New England.

    Rain from Michael

    As this front makes its final pass offshore, it will pull a little bit of the moisture from Michael across Southeastern Massachusetts and that’s why rainfall amounts there will be heavier than they will be in the Greater Boston area. You can see the area of rain moving just to the south of New England early Friday, and this will be after we’ve had showers from the cold front.

    Offshore winds will be gusty

    Pictures of the damage caused by Hurricane Michael will continue to pour in during the day Thursday and throughout the weekend as the storm continues to move out into the Atlantic. It will probably bring some gusty winds to the waters offshore, but beyond rough seas, New England won’t see anything memorable.

    Hurricane Michael will go down in meteorological history with a lot of firsts. It was the strongest storm to ever hit the Florida Panhandle since the records began in the mid-1800s, it’s the strongest storm this far north this late in the season, and it’s perhaps the fastest intensifying hurricane this far north as well. Forecasters will be studying the storm for a long time to understand exactly why the rapid intensification occurred, noting that peak intensification happened at or even just after landfall. The destruction and death caused by the storm means that the name Michael will be forever retired out of the hurricane names book.

    As the storm continues to move up across the Appalachians and eventually off the Mid-Atlantic Coast and then out to sea, it will brush Southern New England. The strongest winds are going to remain offshore and this will be more like a nor’easter rather than a tropical system.

    Into the weekend: Bye bye, summer

    Temperatures were more than 20 degrees above average Wednesday, and days with 20-degree anomalies are quite rare. A cold front now moving in from the west will push this unseasonably warm air out to sea and put an end to the summer pattern that has been going on for the past several months. Saturday will be one of the chilliest days we’ve seen since the spring. Look for a lot of clouds and a couple of showers, but temperatures will be the big story, with highs only reaching the lower to mid-50s in the afternoon. Sunday is a nicer day — still cool, with highs remaining under 60, but there will be plenty of sunshine.

    The overall weather pattern is undergoing a complete flip from what we’ve seen over the past several months, and cooler than average conditions can now be expected for the rest of October, beginning this weekend.
