  Wednesday. 

- A chilly rain likely late Thu into Sat, with some snow
  possible in the higher elevations of MA/CT

&&

.DISCUSSION...
KEY MESSAGE 1...Dry and seasonable weather continues for tonight and
 Wednesday. 

Dry subsident W to NW flow continues into Wednesday as southern New 
England remains under a flattened mid-level ridge. A moisture-
starved shortwave drops southward overnight. This will mainly bring 
a period of breezy conditions overnight, mainly along the coast and 
interior higher elevations overnight. This will also bring in a 
slightly cooler airmass aloft by Wednesday. At most, temperatures 
may be a degree or two cooler than Tuesday. Highs will likely rise 
into the low to mid 50s with the exception of the CT Valley with 
upper 50s in spots. Mid/upper level moisture will support some cloud 
cover mixed in with sunshine. 

KEY MESSAGE 2...A chilly rain likely late Thu into Sat, with some 
snow possible in the higher elevations of MA/CT

Good model (AI and traditional models) agreement on a coastal low or 
series of lows tracking somewhere along or south of New England in 
the Thu-Sat timeframe. Although, there is considerable uncertainty 
in the guidance on multi waves vs one consolidate low, along with 
the magnitude/intensity of each wave. Therefore, large differences 
on QPF, axis of heaviest QPF, along with location/track of dry slot. 
As for ptype, given the lack of cold air (warm blyr), most of the 
region will likely experience a chilly rain, especially the coastal 
plain and big population centers of Boston, Worcester, Providence 
and Hartford. For snow in the coastal plain to occur with this 
setup, a stronger system would be required, with strong height falls 
cooling the column from top down to erode warm boundary layer. Also, 
heavy precip would be required to cool the column via diabatic 
cooling from melting, and models show a very large spread in axis of 
heaviest QPF. Thus, a low confidence forecast on exact storm 
details. As for timing of precip, most 12z guidance, including the 
12z REFS, Thu may begin dry, but by days end, most guidance has rain 
falling over all of MA/CT/RI. 

A look at the ensembles, both AI and traditional models, only one or 
two members from both the EC and GFS ensembles have substantial 
snowfall across MA/CT/RI. Thus, non-zero, but very low probability 
of this happening. Again, it would require a stronger system with 
significant height falls and heavy precip over SNE. Hence, a chilly 
rain for most of MA/RI/CT, with some snow possible across the higher 
elevations of MA/CT.   

As for snow probs from the ensembles, the 12z GEFS ensembles only 
have 10-20% probability for 3+ inches across Northern Worcester and 
the Berkshires. The CMC ensembles are very similar and the 12z ECENS 
have up to 50-60% of 3+ inches across the Berks, with 30-40% over 
Northern Worcester county. 

Ensembles suggest low slowly exits by Sunday, with some height rises 
over SNE. Thus, some improvement Sunday with drier weather and not 
as chilly as Sat, although remaining blustery Sunday. Additional 
improvement comes early next week with further height rises 
promoting seasonable temps (highs low 50s) and dry weather.

Forecaster Confidence Levels...

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

Through Wednesday night...High confidence.

Surface high pressure across the coastal waters tonight and 
Wednesday. Elevated winds continue this evening and early tonight as 
a dry front moves through with gusts 20-28 kts. Opted to keep the 
SCAs going for the outer southern waters and eastern waters since it 
is marginal. Seas 3-6 ft. Winds decrease early Wednesday morning, 
although seas may remain near 5 ft across portions of the southern 
outer waters through the afternoon Wednesday. SCAs will continue 
tonight through 12Z, but it is possible some of the southern zones 
may need to be extended due to the elevated seas.

Outlook /Wednesday Night through Sunday/...

Thursday: Low risk for Small Craft Advisory winds with gusts up
to 25 kt. Seas locally approaching 5 ft. Chance of rain. 

Thursday Night: Moderate risk for Small Craft Advisory winds
with areas of gusts up to 30 kt. Rough seas up to 11 ft. Rain.
