  Bristol County in southeastern Massachusetts...
  Southwestern Plymouth County in southeastern Massachusetts...
  Bristol County in Rhode Island...
  Kent County in Rhode Island...

  torrential rainfall had occurred overnight and early this morning. 
  Flooding is ongoing or expected to begin shortly in the warned 
  area. Between 3 and 7 inches of rain have fallen.

* Many area rivers and streams are still rising, and some will 
  produce flooding during this morning into early this afternoon. In 
  addition, due to the amount of rain that has fallen, a 
  considerable amount of urban and poor drainage flooding will 
  likely take much of the morning or even into early afternoon to 
  fully recede.

* Some locations that will experience flooding include...
  Providence, New Bedford, Fall River, Warwick, Cranston, Pawtucket, 
  Taunton, East Providence, Woonsocket, Coventry, Dartmouth, 
  Cumberland, North Providence, South Kingstown, West Warwick,

What forecasters said that day

The local office's own words before this areal 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 areal flood warning went out at Sep 2, 7:27 AM EDT, 16 minutes earlier.

Area forecast discussion, Sep 2, 7:27 AM EDT, 16 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
727 AM EDT Thu Sep 2 2021

.SYNOPSIS...

Heavy rain ends early this morning and skies clear from west to
east as high pressure nudges in from Ontario. Gusty winds are
still possible across RI and eastern MA into this afternoon.
Drier and cooler conditions arrive this afternoon and linger
into the beginning of the Labor Day weekend, with a touch of
fall Thu night into Sat. Then temperatures moderate Sunday,
Monday and Tuesday, along with a low risk for a few showers from
time to time, but not a washout.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

7 AM Update...

Main change in the latest update was to bring precipitation to
an end quicker than the previous forecast. Leaned toward the
latest HRRRE guidance with winds, gusts and precipitation
chances as it is doing well with current observations. Will see
skies clearing from west to east as high pressure nudges in.
Rest of the forecast remains on track and looks good.

4 AM Discussion...

Highlights

* Heavy rain tapers off this morning, but gusty winds will
  persist across eastern areas into the early afternoon.

Heavy rain tapers off from west to east and should be over with
by roughly 7-8 AM. Dry, but breezy conditions are expected for
much of the day as low pressure lifts out and exits the region.
Still could have a period of damaging wind gusts this morning
into the early afternoon, especially where the Wind Advisory is
in effect given the saturated grounds and gusts up to 45 mph at
times. These winds will slacken as high pressure nudges in from
Ontario relaxing the pressure gradient. Leaned toward the HRRRE
guidance to handle the wind speeds/gusts.

Looks much more comfortable temperature and humidity wise across
southern New England today as high pressure nudges in. High
temperatures range from the upper 60s to low 70s with dew points
in the 50s to low 60s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...

No changes to the previous forecast, dry and much cooler behind
the exiting system. Lows in the 50s regionwide, with upper 40s
in northwest MA. Temperatures on Friday very similar to today
with readings in the upper 60s to mid 70s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...

* Drier conditions behind the remnants of Ida to start the holiday
  weekend
* Warming trend through the weekend and early next week
* Unsettled pattern expected next week

Friday and Saturday

High pressure builds in behind the remnants of Ida on Friday bringing
sunny skies and early fall like conditions to southern New England.
Afternoon high temperatures likely to top out in the mid to upper
70s on these days.

Sunday through next week

As high pressure shifts east late this weekend return flow from the
south will support a warming trend through the middle of next week.
Global models are hinting at a more active jet-stream next week
supporting an unsettled pattern. Next frontal system and
precipitation event may be in the Sunday night through Monday time
frame as global models hint at an upper-level disturbance moving
across the northeast. Stay tuned for details.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...

Forecaster Confidence Levels.

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Today...High confidence in trends, but moderate in timing.

Precipitation ends early this morning and skies clear from west
to east. Conditions gradually improving from IFR/MVFR to
MVFR/VFR mid to late this morning and VFR by the afternoon for
all terminals. As the system exits will have N/NW winds with
gusts of 25-35 kts. Should see the gusty winds ending by late
afternoon/evening as high pressure relaxes the pressure
gradient.

Tonight...High confidence.

VFR with NW winds at 5-10 kts.

Friday..High confidence.

VFR with NW winds at 5-10 kts.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Friday Night through Monday/...

Friday Night through Saturday: VFR.

Saturday Night: Mainly VFR, with local MVFR possible. Chance
SHRA.

Sunday: Mainly MVFR, with local IFR possible. Chance SHRA.

Sunday Night: MVFR/IFR conditions possible. Chance SHRA.

Labor Day: VFR.

&&

.MARINE...
Forecaster Confidence Levels.

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

* Gale Warnings overnight into Thu

Tonight and Thursday...High Confidence. The remnant circulation of
Ida passing near the south coast overnight into Thursday will create
Gale force wind gusts and building seas across the waters overnight
into Thursday. Impressive 925 mb LLJ for this time of year should
allow for NNE wind gusts of 30 to 40 knots to develop after midnight
and shift to the N on Thu. Seas should build to between 7 and 11
feet. Gale Warnings are posted for most waters with Gale Watches
issued for Boston Harbor/Narragansett Bay. We also should mention a
few strong t-storms are possible overnight into early Thursday
morning near the south coast with the potential for a waterspout.

Outlook /Friday Night through Monday/...

Friday: Winds less than 25 kt. Areas of seas approaching 5 ft.

Friday Night: Winds less than 25 kt. Seas locally approaching
5 ft.

Saturday through Saturday Night: Winds less than 25 kt.

Sunday through Sunday Night: Winds less than 25 kt. Seas up to
5 ft. Chance of rain showers.

Labor Day: Winds less than 25 kt. Seas up to 5 ft.
