.WHAT HAS CHANGED...
Increasing confidence for some accumulating snow Wednesday into
Wednesday night across northern MA.
&&
.KEY MESSAGES...
- Some snow showers remain possible tonight into Monday
morning. Minor accumulations with little to no impacts
expected.
- More snow showers possible early Tuesday morning/late Monday
night.
- Multiple rain, snow or mixed wintry precip events possible
from mid week into next weekend. Near seasonable temps.

.DISCUSSION...
Key Message 1...Some snow showers remain possible tonight into
Monday morning. Minor accumulations with little to no impacts
expected.
A period of some light snow remains possible tonight into Monday
morning, particularly towards the south coast, as a coastal storm
passes to our south. Some snow showers in western MA into parts of
CT are a possibility as well.
The latest guidance has continued to show a coastal storm associated
with a southern stream shortwave track to our south and a northern
stream shortwave moves into the northeast from the Great Lakes
heading into tonight. Even with these waves tracking at roughly the
same time, they don't phase with each other by the time they reach
southern New England. We may still see impacts from the coastal
storm though, mostly in the way of light snow along the south coast.
The northern wave may also bring some light snow showers to parts of
the interior; some slightly elevated PWATs there could help
facilitate some showers, but not much is expected outside of
western MA.
In terms of accumulations, no more than a trace to a few tenths
of an inch are expected for both the south coast and parts of the
interior. And with daytime highs Monday getting into the mid to
upper 30s, the light accumulations that we could pick up overnight
will likely melt away during the day. The 75th percentiles have at
most a few tenths of an inch for parts of southern CT and western
MA, and the 25th percentiles continue to show no accumulations at
all.
Key Message 2...More snow showers possible early Tuesday
morning/late Monday night.
Drier conditions through the afternoon Monday after any early snow
showers towards the south coast. Another shortwave approaches
southern New England Monday night into early Tuesday morning and
PWATs increase to at/just below 0.5" as it arrives. With the lift
from the wave and that increased moisture from some light WAA, some
light snow showers and flurries are possible early Tuesday morning.
The highest PoPs are in western and central MA into parts of CT,
though even then, it is only a slight chance (at or below 20 percent
chance). This wave clears out of southern New England by the
afternoon, and the already lower chances for some spot snow showers
will continue to decrease.
Key Message 3...Multiple rain, snow or mixed wintry precip
events possible from mid week into next weekend. Near seasonable
temps.
An active Pacific jet with a parade of shortwaves traversing
the CONUS will bring an unsettled pattern to New Eng with
multiple precip events from midweek into next weekend. The -PNA
pattern with modified Pacific flow will keep arctic well to the
north but not that mild here with temps mostly averaging around
seasonable norms but periods of colder than normal temps
possible. While there is high confidence in an unsettled period
in SNE, it's a rather complex pattern with many shortwaves
moving through the flow leading to lower predictability in the
finer details of timing of precip events and distribution of
ptype across the region.
There is better agreement that the first system will impact the
region sometime Wed into Wed night as shortwave energy lifts NE
from the Gt Lakes, although exact timing, axis of heaviest
precip and ptype is still in question. The surface boundary will
likely set up near or south of SNE coast with a secondary wave
tracking along it which should help to lock in low level cold
air, especially across northern MA where best chance for
accumulating snow. But some of the ensemble members including a
majority of EPS members keep axis of snow further N. These are
details which will need to be ironed out over the next 24-48
hrs. Low levels are clearly warmer further south and suggest
more rain south of the MA Pike although can't rule out some snow
here if boundary and low track end up further south. Best
chance of plowable snow will be across northern MA. GEFS
indicating 40-70% probs for greater than 3 inches of snow in
northern MA, while EPS showing 20-40% probs with highest probs
to the north.
Model consensus favors mainly dry conditions Thu with temps
near or a bit below normal in the 30s as system pulls away and
high pres builds in from the north. Then forecast confidence
decreases significantly Friday into next weekend as multiple
shortwaves within the active subtropical jet approach New Eng
from the SW. Lots of uncertainty with how global guidance
handles these shortwaves and whether there will be multiple
weaker systems Fri through Sun or a stronger storm to impact
the region. However, more accumulating snow is possible for
portions of SNE during this time period. Overall a very active
weather pattern.

Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Through Monday night...High confidence.
Seas 2-3 ft through tonight are expected before a deepening low
pressure moves off the Mid-Atlantic coast tonight through early
Monday morning that will result in building seas into Monday. Seas
may approach Small Craft Advisory criteria by Monday night/early
Tuesday morning.
As the deepening low passes to our south, some elevated E to NE
winds in the southern waters are possible for Monday with gusts to
around 20 kt. Winds over the northern and eastern waters remain at
or below 10 kt. Some light snow showers are possible tonight
into Monday over the southern waters associated with the
passing low.
Outlook /Tuesday through Friday/...
Tuesday through Tuesday Night: Winds less than 25 kt. Seas up
to 5 ft.
Wednesday: Winds less than 25 kt. Seas up to 5 ft. Rain likely.
Wednesday Night: Winds less than 25 kt. Seas up to 5 ft. Rain
likely, chance of snow.
Thursday: Winds less than 25 kt. Seas up to 5 ft. Slight chance
of rain, slight chance of snow.
Thursday Night: Winds less than 25 kt. Seas locally approaching
5 ft. Slight chance of rain.
Friday: Winds less than 25 kt. Areas of seas approaching 5 ft.
