.KEY MESSAGES...

- Seasonable conditions continue through tonight.

- A storm system will bring a prolonged period of rain to much
  of southern New England Thursday through Saturday with periods
  of snow in the higher elevations. Significant accumulation is
  not expected. 

- High pressure brings cool and dry conditions back to southern New 
England for the start of the next work week.

.DISCUSSION...
KEY MESSAGE 1...Seasonable conditions continue through tonight.

Persistent WNW flow continues through this evening, bringing 
seasonable temperatures and dry conditions ahead of the next storm. 
High temperatures today remain similar to yesterday... in the mid 
50s. A dry shortwave pushing through before sunrise will allow for 
some wind gusts 20 to 25 mph in the higher elevations and coastal 
plain through mid-morning before conditions slowly calm through the 
afternoon.

KEY MESSAGE 2...A storm system will bring a prolonged period of rain 
to much of southern New England Thursday through Saturday with 
periods of snow in the higher elevations. Significant accumulation 
is not expected. 

A vertically stacked trough of low pressure over the Ohio Valley 
will pass over the Mid-Atlantic on Thursday, strengthening as is 
moves into the waters south of New England Thursday night and lifts 
into the Gulf of Maine Friday night. This leads to a prolonged 
period of unsettled weather, even continuing into Saturday thanks to 
the slow progression/trailing behind of the upper trough/cold pool 
aloft. Light to moderate warm advection rain will expand over 
southern New England on Thursday as the low approaches. Eventually a 
cooler airmass is pulled down as flow around the low backs to the 
north and northwest while the mid/upper levels cool with the arrival 
of the trough. This, together with some diabatic cooling will allow 
for places in the high terrain of the Berkshires and Worcester Hills 
to flip to snow by Thursday night. However, given the lack of 
antecedent cold air in the boundary layer those outside of the 
higher elevations will more likely experience a cold rain for most 
if not all of the period. The decidedly mild airmass in place over 
the last week will not bode well for much in the way of 
accumulation. Model soundings show a lack of omega in the snow 
growth zone as well as a dry slot which may move in overnight 
Thursday cutting into potential snowfall amounts. Ensemble guidance 
is fairly steady in showing only a few outlier members with 
substantial snowfall across MA/CT/RI; probabilities of AOA 3" in the 
Worcester Hills range from 10-30% (both EPS and GEFS) but keeping in 
mind these are using 10:1 SLR while in reality they would be less. 
In early season situations like this it is often useful to utilize 
the positive snow depth change guidance as a more realistic 
expectation; thus, continuing to expect a low impact event with only 
minor accumulations in the highest terrain. That being said, as we 
get in range of the higher resolution guidance we will continue to 
evaluate and update the forecast based on the newest
information. 

KEY MESSAGE 3...High pressure brings cool and dry conditions back to 
southern New England for the start of the next work week.

As the low slowly pushes further into Atlantic Canada, high pressure 
begins to build over the Great Lakes Sunday into Monday. The tighter 
pressure gradient will allow blustery conditions to linger through 
Sunday, but the strengthening high will mark the return of a dry 
period through the start of the next work week. High temps slowly 
climb through the early week... in the upper 40s Sunday to the mid 
50s Tuesday/Wednesday.
