.WHAT HAS CHANGED...
Flood Watch continues for today and tonight across RI and
southeast MA. Guidance trended slightly farther north with 
axis of heaviest rainfall.

Otherwise, overall forecast remains in good shape.

&&

.KEY MESSAGES...

- Widespread rain arrives today and continues tonight before
  tapering off early Saturday. Rain will be heavy at times
  across RI and southeast MA, including Cape Cod and the
  Islands. 

- Unsettled weather continues into this weekend, then cooler 
  and drier conditions arrive next week.

&&

.DISCUSSION...
KEY MESSAGE 1...Widespread rain arrives today and continues
tonight before tapering off early Saturday. Rain will be heavy 
at times across RI and southeast MA, including Cape Cod and the
Islands.

Still trying to pinpoint the axis of heaviest rainfall. Some of
the latest guidance have shifted this axis slightly farther
north, owing to a slightly slower timing of a cold front. Still
have the greatest confidence in the heavier rainfall across RI 
and southeast MA. 

Temperatures remained well above normal for early November.
Expecting low temperatures this morning to be higher than our
normal high temperatures. A few records See the climate section
below for more details. 

Still strong signals for a significant rainfall across our
region into Saturday. Thus, not much change to the overall
forecast. There was some lightning around midnight south of 
Long Island, as well as a few flashes south of Cape Ann more
recently. A few thunderstorms remain a possibility. Thus far, 
it has not been particularly widespread, but will keep a broader
mention of thunderstorms in the forecast due to the supporting 
dynamics. 

Rainfall totals were not changed substantially. Continue to have 
high confidence for 1-3", with lower probabilities for isolated
4-5". This might result in urban/poor drainage flooding,
including the typical flood prone areas of New Bedford, Fall 
River, Providence, Cranston, etc. Given the time of year, leaf 
clogged drains will only exacerbate the urban/poor drainage 
flood potential. Regarding small rivers and streams in RI and 
southeast MA, 4+ inches would be required for minor flooding. 
Hence, looking more like a poor drainage/urban flood potential. 
Elsewhere across CT into northern MA, less rainfall is expected.
Thus, the flood threat is limited to RI and southeast MA. Given
the flood potential and uncertainty in the exact location of 
heaviest rainfall, a Flood Watch continues to message the 
threat for flooding. 

Rainfall chances initially diminish Saturday morning with a 
lull in the precipitation. Will see a resurgence in rainfall
chances Saturday afternoon into Saturday night as the colder
core of an upper level low moves overhead. The anomalously 
cold air aloft paired with partial clearing at the surface 
likely results in steep lapse rates and widespread showers. A 
few showers may be capable of producing heavy rainfall and small
hail as strong cold air advection cools the mid levels of the 
atmosphere.

KEY MESSAGE 2...Unsettled weather continues into this weekend, 
then cooler and drier conditions arrive next week.

In the wake of today's system, surface low pressure develops in
the Gulf of Maine Saturday night into Sunday morning. This low 
shifts off to the north and east through Sunday morning while 
the core of an upper level trough steadily follows it from the 
west. This core is expected to move over southern New England 
over the same time period, and with it, much cooler temperatures
aloft. Temperatures at 500 mb dip to around -20C, with some 
guidance falling to -25C. Closer to the surface, temperatures at
925 mb fall to around 2-4C and temperatures at 850 mb fall to 
around 0C by early Sunday morning. Once the upper level trough 
clears off to the north and east, 850 mb temperatures improve 
slightly to just around 2C. This colder air aloft will be more 
supportive of highs Sunday into the start of next week falling 
back to the 50s with cool nights in the 30s and 40s.

NAEFS guidance indicates no significant deviations from the  
climatological percentiles for temperatures or moisture for the
next week, though did note 90th percentile zonal winds aloft 
Monday into Wednesday across much of the region. Persistent 
westerly flow with notably breezy conditions Monday and Tuesday 
is expected. Winds generally stay westerly through much of the 
week, given the series of fronts expected to move through the 
region. With the drier conditions (PWATS to around 0.5" and less
and dew points back in the 30s and 40s) at the surface, not 
much in the way of precipitation is expected with these frontal 
passages; just cooler air. Occasional cloudiness is expected at 
most with passing moist air aloft.

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
Forecaster Confidence Levels...

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

Today and Tonight...High confidence on trends, lower confidence
on exact timing and details. 

Widespread LIFR/IFR in periods of rain, heavy at times across RI 
and southeast MA terminals. Low risk of -TSRA, especially off 
the south coast of RI/SE MA. 

More of the same tonight. IFR conditions in periods of rain, 
locally heavy at times across RI and southeast MA. As wave of 
low pressure tracks along the south coast and then exits the 
canal, winds will shift to the N-NE. Low risk of marginal LLWS
as low level southwest jet of 40-45 kt moves across RI and
southeast MA. 

Saturday...High confidence on trends, lower confidence
on exact timing and details.

Slow improvement from W to E from IFR to mainly MVFR. Areas
towards SW New England could be VFR during the afternoon.

KBOS Terminal...High confidence in trends, moderate confidence 
in exact timing and exact details. Brief lull this morning, but
SHRA returns towards 14Z. Visibilities may fall to IFR before 
20z in any periods of heavier rainfall, but uncertainty remains 
on exact timing.

KBDL Terminal...High confidence in trends, moderate confidence
in timing and exact details. Visibilities may fall lower than
2SM in any periods of heavier rainfall during the day. Ceilings
could flirt with LIFR, but confidence is just too low to include 
in TAF for now.

Outlook /Saturday Night through Tuesday/...

Saturday Night: Mainly VFR, with areas IFR possible. Breezy.
Chance RA.

Sunday: Mainly VFR, with local MVFR possible. Breezy. Chance

Sunday Night through Tuesday: VFR. Breezy.

A cold front is still expected to stall across eastern New
England this afternoon. A low pressure traverses this front,
reaching eastern MA tonight, then moving east across the waters
Saturday. Main impacts will be from areas of moderate to heavy
rainfall with poor visibility at times. A few thunderstorms are
possible as well.

Rough seas expected across the southern coastal waters. Posted a
Small Craft Advisory for those waters. Seas subside some tonight
as winds diminish.
