.KEY MESSAGES...

- Mainly dry through Thursday Night with the exception of a few
  light snow showers this evening and overnight.

- Mostly dry through this weekend except a low chance for light
  nuisance snow Saturday. Temperatures make a return to near
  normal. Attention turns to late this weekend for a potential 
  coastal storm, but forecast confidence remains low due to 
  track uncertainty.

.DISCUSSION...
KEY MESSAGE 1...Mainly dry through Thursday Night with the
exception of a few light snow showers this evening and
overnight. 

A mid level shortwave passes by southern New England late today
into tonight. WHile this may be enough to trigger a few snow
showers during this time, there is not much lift or humidity
expected within the dendritic growth zone. Thus, really looking
more like flurries over land. Over the coastal waters, could be
a different story where some ocean effect processes can help to
enhance the shower risk, which would be mainly a cold rain over
the eastern MA coastal waters this evening.

Colder air moves over our region late tonight, so expecting low
temperatures to be 5-7 degrees lower than what we saw this
morning. This trend looks to continue through Thursday night.

KEY MESSAGE 2...Mostly dry through this weekend except a low 
chance for light nuisance snow Saturday. Temperatures make a 
return to near normal. Attention turns to late this weekend for 
a potential coastal storm, but forecast confidence remains low 
due to track uncertainty.

High pressure builds in over the Midwest/Mid-Atlantic regions
later this week, finally pushing the arctic airmass offshore,
bringing southern New England back to seasonable temperatures.
High temperatures rise into the mid to upper 30s, though
overnight lows will still fall into the teens and low 20s, with 
some spots in the interior in the single digits. 

Another upper-level low moves through Friday night, bringing
chances for another quick shot of snow showers to southern New
England early Saturday morning. The latest NBM guidance
indicates probabilities 20- 30% chance of seeing 0.1" of snow
across eastern MA as PWATs remain only about 75% of normal.  
Heading into next week, guidance continues to indicate potential
impacts from another storm moving across Texas and off the
southeast Atlantic coast. Uncertainty in the timing and track 
only increases exponentially at that point, with the latest
ensemble suite slowing the development of the low and increasing 
the spread of possible tracks. The Canadian ensemble indicates
the closest track, passing just south of Nantucket, while the 
ECMWF ensemble shows the low passing south of the 40N/70W 
benchmark. The GFS ensemble struggles to resolve the low, with 
several members indicating the low may not remain organized as 
it moves offshore. Continued with low-end PoPs for Sunday night 
into Monday given the high amount of uncertainty at this point.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
Forecaster Confidence Levels...

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

Through 00Z...High confidence.

VFR CIGS with gusty NW winds up to around 25 kt. Can't rule out
the low risk for an isolated flurry/light snow shower late this
afternoon into this evening, mainly across western MA/CT. But
could also be across portions of NE MA.

Tonight...High confidence.

VFR. Breezy NW winds with gusts up to 20 kt.

Thursday...High confidence. 

VFR. Breezy NW winds with gusts 20-25 kts. Few snow showers
possible over outer Cape Cod in the morning, but should be
mainly over the waters to the E.

Thursday Night...High confidence.

VFR. Gusty NW winds up to 20 kt.

KBOS Terminal...High Confidence. 

Low risk for a snow shower during the evening push. Hinted at
this with a P6SM -SHSN, but the greater risk will be over the
waters east of the terminal. Not anticipating much snow
accumulation. 

KBDL Terminal...High Confidence.

Outlook /Friday through Monday/...

Friday through Friday Night: VFR. 

Saturday: VFR. Breezy. 

Saturday Night through Sunday: VFR. 

Sunday Night: VFR. Slight chance SN.

Washingtons Birthday: VFR. Breezy. Chance RA and SN.

&&

.MARINE...
Forecaster Confidence Levels...

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

Through Thursday Night...High Confidence.

Low pressure south of the Maritimes will swing an inverted
trough over the coastal waters tonight. This could trigger
scattered rain showers, at least until colder air arrives after
midnight, when snow showers would be favored over the eastern
coastal waters. Gusty NW winds persist as well. Toward daybreak
areas of freezing spray are likely, especially the nearshore
waters of MA and RI.

Outlook /Friday through Monday/...

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

Sunday: Winds less than 25 kt. 

Sunday Night: Winds less than 25 kt. Slight chance of rain,
slight chance of snow. 

Washingtons Birthday: Winds less than 25 kt. Seas locally
approaching 5 ft. Chance of rain.
