.KEY MESSAGES...

- The historical blizzard impacting RI and eastern MA will
  gradually wind down through the afternoon and early evening. 
  Strongest gusts along SE New Eng coast will slowly diminish 
  late afternoon and evening. 

- Another round of minor coastal flooding along the eastern MA
  coast during the late afternoon high tide, with pockets of low
  end moderate flooding along Nantucket Harbor and Cape Cod Bay
  from Sandwich to Dennis.

- Mostly clear day Tuesday gives way to an unsettled pattern 
  for the mid and late week timeframe. A clipper system may 
  bring precipitation Wednesday and a warm front has the 
  potential to bring yet another round of unsettl ed weather by 
  Friday.

.DISCUSSION...
KEY MESSAGE 1...The historical blizzard impacting RI and 
eastern MA will gradually wind down through the afternoon and 
early evening. Strongest gusts along SE New Eng coast will 
slowly diminish late afternoon and evening. 

The persistent mesoscale snow band hammering RI and SE MA is  
weakening as low pres has moved east of the benchmark and
heading offshore. This trend will continue through the 
afternoon with snowfall rates gradually diminishing as the low 
pulls away. May still have an hour or 2 of 1-2"/hr snowfall 
rates before the snow lightens up and eventually ends early 
this evening. Max snowfall from this storm will be 2-3 feet 
confined to RI and SE MA.

Peak of the wind is occurring now across SE coastal MA and 
Cape/Islands within the core of the low level jet. Wind gusts 
to 60- 80 mph here will gradually diminish mid to late afternoon
with 50-60 mph gusts lingering into the early evening before 
diminishing further through the night as the LLJ weakens and 
moves offshore. 

Otherwise, drying out tonight with partial clearing overnight 
across SNE with lows dropping into the teens, with lower 20s 
along the immediate coast. 

KEY MESSAGE 2...Another round of minor coastal flooding along the 
eastern MA coast during the late afternoon high tide, with pockets 
of low end moderate flooding along Nantucket Harbor and Cape Cod 
Bay from Sandwich to Dennis.

Currently observing a 4.2 ft surge at Nantucket with likely 
similar surge at Dennis. Expect the surge to come down a bit as 
we approach high tide late this afternoon but still looking at a
3-4 ft surge here. This will bring widespread minor flooding to
Nantucket and Cape Cod from Sandwich to Dennis, with pockets of
low end moderate possible. 

For the rest of the east coast, we're looking at a 2-3 ft surge 
which will bring pockets of minor flooding from Plymouth 
northward. 

Again, the most significant impacts for the late afternoon high
tide will be at Nantucket and along Cape Cod Bay with widespread
minor to pockets of low end moderate flooding. 

KEY MESSAGE 3... Mostly clear day Tuesday gives way to an
unsettled pattern for the mid and late week timeframe. A clipper 
system may bring precipitation Wednesday and a warm front has
the potential to bring yet another round of unsettled weather by 
Friday. 

After lows in the teens and single digits Tuesday night, a
clipper system emerges from the Great Lakes region Wednesday. A 
trailing warm front ahead of it brings a chance for some more
wintry precipitation with the highest probs of accumulations in 
the interior. Elsewhere across the coastal plain thermal
profiles appear to be marginal with surface temps warming into
the mid and upper 30s. NBM has the highest probability for 1
inch of snow or greater snowfall totals in the Worcester Hills
and Berkshires. Snow may accumulate at lower elevations if the 
timing of the front but expecting temperatures to quickly warm 
into middle and upper 30s by the afternoon. 

Temperatures will have quite a significant diurnal variation
Tuesday night through Wednesday with lows falling well below
freezing and highs warming into the upper 30s. These warmer
daytime temperatures will result in melting and refreezing of
any melted snow, leading to slick conditions on untreated
walkways. 

Ensemble guidance is hinting at impacts from another area of low
pressure Thursday night into Friday. Details on the exact track 
and strength are highly uncertain at this time. That being said,
ensemble guidance has shown the possibility of a track north and 
west of our CWA which result in more of the way of mixed
precipitation. Again, we are nearly 6 days away from this system 
so exact details will be resolved in future forecast updates.

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Forecaster Confidence Levels...

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

18Z TAFs: Moderate confidence (60%). Timing of improvement may
be +/- 1-2 hours off.

Slow improvement through the evening as bands of heavy snow
gradually push offshore. Strong winds will continue to reduce
visibilities in BLSN even though snowfall rates will decrease,
but that should subside overnight as well. VFR Tue with
diminishing NW winds backing to W in afternoon. 

Fast moving system should bring -SN later Tue night with MVFR. 

KBOS Terminal...Moderate confidence in TAF. Timing of
improvement may be 1-2 hours too fast. Also some uncertainty on
how much BLSN will reduce visibility through early tonight.

KBDL Terminal...Moderate confidence in TAF. Fairly confident on
timing of improvement but less certain on how much BLSN will 
reduce visibility through early tonight.

Outlook /Wednesday through Saturday/...

Wednesday: Mainly IFR, with local MVFR possible. Breezy. SN,
slight chance RA.

Wednesday Night: VFR. Breezy. 

Thursday: VFR. Chance SN, slight chance RA.

.MARINE...
Forecaster Confidence Levels...

Low - less than 30 percent.

evening. Peak of the gusts occurring this afternoon across eastern 
MA waters with peak gusts 55-65 kt. Winds have begun to diminish a 
bit over RI coastal waters and this weakening trend will reach 
eastern MA waters this evening as the low level jet moves offshore. 
Winds are expected to fall below gale force after midnight over the 
eastern MA waters.

Outlook /Wednesday through Saturday/...
