The Nor’easter has definitely lived up to expectations

 

Surface Chart, Radar and Satellite

 






This powerful nor'easter slammed the East Coast this weekend with heavy rain and high winds causing major flooding in the Jersey Shore into New York City. After hitting New Jersey, the nor’easter will be heading toward Long Island today, then it will pass close to Nantucket later tonight into Monday morning, as it heads for the Gulf of Maine on Monday, before moving into the Canadian Maritimes Monday night into Tuesday.







As it follows this track the nor’easter should gradually weaken on Sunday, though its impacts will continue into Monday, including on-and-off rain showers, gusty winds and some coastal flooding. As the impacts shift into New England, southern New England will be dealing with isolated inland flooding, along with gusty winds gusting 40-60+ mph, coastal flooding and beach erosion through Monday. Across New England the heavier and steady rain will be waning by Tuesday morning. Across western New England into Eastern New York State wind gust of 20-30 mph can be expected in the lower elevations, while gust of 35 to 45 mph will be possible in the highest elevations of the Catskills, southeast Adirondacks, Taconics, Berkshires and southern Greens. This area can also expect periods of rain tonight and tomorrow.

As this slowly weakens the wind field is going to be expanding. So, areas farther inland in Southeast New York State and New England will see gustier conditions, southeastern New Hampshire, especially the seacoast into southern Maine will likely be dealing with wind gust of 25-40 mph, but tomorrow into Tuesday the winds will slowly drop back.  The worst of today’s rainfall will be northern New Jersey through New York City/ Long Island into southern New England. Then the steadier rain looks to work into southern Maine where a couple of inches will be possible into Monday. But by then the storm will be much weaker than it has been.

Behind the departing nor’easter temperatures will be turning milder for Wednesday and Thursday. Then another disturbance approaches and moves through later Thursday and Friday, bringing rain back into the region.

I’ve been working on the first installment of the 2026-2027 winter outlook, that I will be releasing in a couple of days.
