What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Boston/Norton, MA wrote its last area forecast discussion before this river flood warning went out at Sep 27, 7:59 AM EDT, 3 hours 54 minutes earlier. Its key messages:

  • The worst of the wind is behind us but windswept rain with minor coastal flooding/beach erosion and potential for some localized urban and street flooding persists into Monday.
  • Marked improvement Tuesday, followed by mainly dry and warmer weather for the remainder of the week.
Area forecast discussion, Sep 27, 7:59 AM EDT, 3 hours 54 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
759 AM EDT Sun Sep 27 2026

.WHAT HAS CHANGED...
The worst of the wind is over. High Wind Warnings and Wind
Advisories for eastern MA and RI have been cancelled.

&&

.KEY MESSAGES...

- The worst of the wind is behind us but windswept rain with
  minor coastal flooding/beach erosion and potential for some
  localized urban and street flooding persists into Monday.

- Marked improvement Tuesday, followed by mainly dry and warmer
  weather for the remainder of the week.

&&

.DISCUSSION...
KEY MESSAGE 1...The worst of the wind is behind us but windswept
rain with minor coastal flooding/beach erosion and potential for
some localized urban and street flooding persists into Monday.

Monitoring the progress of our Nor'easter on satellite we can see
the center of circulation already starting to move west into New
Jersey. It takes the core of the low level jet with it, thus, the
worst of the wind is over with for southern New England. High Wind
Warnings have been dropped as have Wind Advisories for eastern MA
and RI while we'll continue those advisories for CT and
western/central MA through the morning for any pockets of damaging
wind we may see over the next several hours. Generally expecting NE
winds to continue to gust as high as 30-40 mph today. For the second
half of the weekend we'll continue to deal with widespread,
windswept rainfall, heavy at times, which over the course of the
next two days will add up to 2-4 inches for most. Some locations may
see as much as 5-7 inches. For that reason, the Flood Watch
continues through Monday though the long duration of the rainfall
will help to mitigate flooding issues. Turning attention to the
coast, we will continue the Coastal Flood Warning and Advisory for
the east and and south facing coasts respectively. As we've
mentioned over the past several days, combination of the prolonged
NE winds and high astronomical tides will contribute to coastal
erosion and potential for minor coastal flooding through at least
Sunday, potentially into Monday. Fortunately both Nantucket and
Boston managed to stay under flood stage with the overnight high
tide, but will continue to approach flood stage over the next few
high tide cycles along with locations up and down the coast.

KEY MESSAGE 2...Marked improvement Tuesday, followed by mainly dry
and warmer  weather for the remainder of the week.\

By Tuesday our low pressure system meanders its way offshore finally
ushering in winds from a different direction (namely, from the NW).
As the steering flow becomes more zonal going into the middle and
latter part of the week we'll see some movement and even some rising
mid level heights. Along with a markedly drier pattern this allows
for a warming airmass with 850mb temps rising from around 10C to
near 15C by late week which spells a nice, if brief, warm-up back
into the mid/upper 70s late week before our next cold front brings
cooler weather and perhaps some unsettled weather end of week.
