.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.
