Area Forecast Discussion
National Weather Service Boston/Norton MA
655 PM EST Wed Dec 11 2024

.SYNOPSIS...
A strong cold front approaching from the west will bring periods of
heavy rain into this evening along with a round of strong to
damaging wind gusts later today into this evening. The heavy rain
may also result in some stream/mainstem river flooding along with
the risk for localized urban flooding. Dry, blustery and seasonable
temperatures on tap for Thursday behind this system. Below normal
temperatures and dry conditions expected Friday and Saturday.
Sunday through early next week trends more unsettled with
periods of precipitation possible with normal to slightly above
normal temperatures.

&&

.NEAR TERM /UNTIL MIDNIGHT TONIGHT/...
7PM Update:

A fine line has developed across the southern coastal waters in
response to the strengthening LLJ and up to 250 J/kg of MUCAPE.
Have seen lightning activity increase over the last 30 minuets
as it move towards the Cape and Islands. Otherwise current
forecast remains on track. Latest hi-res guidance has rain
moving offshore just after midnight. Gusty WNW winds of 30-40mph
continue through the night even after the rain ends.

Key Messages:

* Additional rainfall of 1-2", locally 3" through tonight.

* Some stream/mainstem river and localized urban flooding possible.

* Strong to damaging wind gusts up to 50-60mph this afternoon and
  evening, easing slightly after midnight.

* Thunder risk is low, but cannot rule out a isolated rumble of
  thunder.

This afternoon through the first-half of the night will be the worst
of this dynamic system. A deep trough extends southward near the
Gulf of Mexico and with a robust LLJ, anomolous PWATs are being
advected northward. The result will be a period of strong to
damaging wind gusts, periods of heavy rain along with the potential
for some flooding and perhaps a few embedded thunderstorms ahead of
the approaching cold front.

List of impacts:

1. Heavy Rain and Flooding Potential:

A round of torrential rainfall early this afternoon will give way to
a brief lull, especially along I-95 from Providence to Boston for
the first-half of the evening commute, while widespread rainfall
continues across the rest of SNE. Driving these heavier bouts of
rain are the anomolous PWATs, those surge into afternoon/evening
between 1.5" to 1.9", which is 3 to 4 standard deviations above
normal, accompanied by strong forcing with a southerly LLJ of 80-90+
knots developing at 925mb. The combination of anomolous PWATS and
strong forcing results in a windswept heavy rain for the remainder
of the afternoon and evening. An additional widespread 1.0" to 2.0",
with locally as much as 3.0" across eastern CT is expected, on top
of the 0.5" to 1.0" which fell earlier today. A lot of this heavy
rain coincides with the evening commute and result in the potential
for localized urban flooding. A Flood Watch remains in effect for
much of the area, away from Boston, mainly for small stream and
river flooding. A quick look at area rivers, the CT River from
northern MA down through CT bares watching due to todays rain and
the snowmelt from the north. CT River at Montague has a 49% chance of
exceeding minor flood stage by Thursday morning, while the CT River
at Middle Haddam has a 47% chance of exceeding minor flood stage by
Friday night. Something we will continue to monitor across all of
SNE.

As for the fine line, CAMs continue to indicate there is the
potential for a fine line to develop and move across SNE late this
afternoon into the evening. Whether or not there is thunder remains
uncertain, as there is little instability. BUFKIT soundings show
little MUCAPE, less than 250 units. Will continue an isolated chance
of thunder into this evening, though it is looking less likely. The
bigger issue, is the transportation of the stronger winds to the
surface.

2. Strong to Damaging Wind Gusts:

Mentioned above, 925mb LLJ is rather impressive with a southerly jet
between 75 and 95 knots, and will be on top of our region late this
afternoon into the early evening. We will be able to tap into the
robust jet and mix down gusts 50 to 60 mph, across SE MA, RI, and
area east of I-495 in northeast MA, with potentially isolated higher
gusts along the immediate south coast. As for areas west of I-495
and across CT, winds aloft are not as strong, and should result in
gusts 40-50 mph. A High Wind Warning remains in effect for eastern
MA, RI, and neighboring southeast CT. Elsewhere, a Wind Advisory
also continues to remain in effect for northern CT and central MA.

3. Nuisance Coastal Flooding for northern Narragansett Bay:

Very nuisance coastal flooding is possible for the northern extent
of Narragansett Bay at the afternoons high tide, 4:17pm, and may
continue for a few hours post high tide due to the persistent
southerly flow. Currently, the forecast of Fox Point is 6.3 MLLW and
this falls below Minor Flood which is 7.0'. We have opt to not issue
and coastal flood headlines as a result. &&

.SHORT TERM /MIDNIGHT TONIGHT THROUGH THURSDAY NIGHT/...

The rain and strongest winds will begin to diminish after midnight
as the cold front races off shore. Behind it, still will have gusty
westerly winds 20 to 30 mph. Skies will be slower to clear tonight
but will trend towards clear by sunrise tomorrow. With falling
temperatures overnight into the the low 30s cannot rule out some
patchy black ice. But given the elevated winds tonight, the it
should preclude any widespread black ice to form. Areas that are
protected from the wind would stand the best chance of having black
ice form.

Chilly and breezy conditions into Thursday as high pressure builds
in from the west. With the cyclonic flow, a few snow showers from
the Great Lakes may approach western SNE. Otherwise more in the way
of sunshine, breezy west winds 25 to 30 mph continue, with highs in
the 30s to 40F, but will feel as if it were in the 20s to low 30s.
Dry and cold conditions continue overnight with lows falling into
the teens and 20s with diminishing westerly winds. &&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Key Messages:

 *Dry conditions with below-normal temperatures Friday through the
  weekend

 *Warming up next week with unsettled weather

Polar high pressure continues to build in for the weekend, keeping
conditions dry. Temperatures on Friday and Saturday will be below
normal in the low to mid-30s for highs and low to mid-teens for
lows. Friday will feel the coldest, with gusty west winds bringing
the feel-like temperatures down into the low 20s. Temperatures on
Sunday begin to warm to the upper 30s to the low 40s. Skies Friday
and Saturday remain mostly clear, turning more cloudy Sunday ahead
of our next potential system Monday.

Polar high pressure moves off to the east, allowing a warming trend
to begin early next week. Several weak shortwaves will pass through
the region over the next week, bringing back a more active and
unsettled pattern. Timing these systems along with Ptype is very
uncertain, with large spread in global deterministic and ensemble
guidance.
