.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.
