.DISCUSSION...
KEY MESSAGE 1...Mostly sunny, cool and blustery Monday. Could 
see a few rain/snow showers Monday night into Tuesday.

A upper-level trough moving through the Great Lakes and into 
New England will bring a cold pool aloft, with 850mb 
temperatures around -5C and 500mb temperatures below -30C. A 
shortwave then moves through, which would help support some 
light snow showers possibly developing and mixing in with rain 
showers, especially over the higher elevation areas. Guidance 
has trended towards a later start, perhaps after midnight/early 
Tuesday morning instead of Monday... though we can't rule out a 
stray shower developing today in the higher elevations. Surface 
temperatures will likely hover near or possibly just below 
freezing Monday night into Tuesday morning, but they're expected
to make a fast recovery later Tuesday morning... into the low 
to mid 40s. A secondary shortwave moves through later Tuesday 
and may allow showers to linger through part of the day, but not
expecting much in the way of rain totals.

KEY MESSAGE 2...Later in the week looks to remain mostly dry with 
temperatures on the rise.

Drier conditions and southwesterly flow are expected to return 
to southern New England as a large high pressure system moves 
into the Mid-Atlantic region Wednesday. Temperatures will 
improve throughout the second half of the week as the upper 
level trough moves off to the east and a warmer airmass advects 
into the region. Expecting highs to rebound into the 50s by 
Thursday and further improve into the 60s by Friday. However, 
some uncertainty remains towards the end of the week as some 
ensemble guidance hints at another backdoor front moving in 
Saturday night into Sunday. High pressure moving east from just 
to our north could encourage onshore flow early Sunday morning 
and possibly continuing through the day before it shifts further
offshore and winds return to SW.

.AVIATION /12Z MONDAY THROUGH FRIDAY/...
Forecaster Confidence Levels...

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

Today: High confidence.

VFR. NW winds increasing through this morning to 12-17 kt and 
gusts 25-35 kt, with the highest gusts across the higher 
terrain. 

Tonight: High confidence overall, though moderate on possible 
precip chances. 

Disturbance aloft moves through Southern New England tonight, 
which will bring at least SCT-OVC cloud deck, mainly VFR 
ceilings. Less confident on if any precip with sweep through, 
but potential exists for brief periods of MVFR visby under light
SHSN. NW winds decrease to 8-12 kt with gusts in lower 20 knot 
range.

Tuesday: Moderate confidence.

Could see some -SHSN spreading east across SNE early Tues AM, 
but not very confident on exact timing or if anything will 
manifest at BOS. Generally W winds 10-15 knots with occasional 
gusts 20-25 knots possible. 

KBOS Terminal...High Confidence in TAF.

KBDL Terminal...High Confidence in TAF.

.MARINE...
Forecaster Confidence Levels...

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

High confidence.

SCAs continue through most of today with seas at or above 5 ft 
across most waters and SW winds gusting 25-30 kts. Guidance has 
lowered on wind speeds tonight into Tuesday morning, so elected
to allow SCAs to expire later this afternoon.

Seas remain below 5 ft through Tuesday, but some northwesterly 
wind gusts may approach SCA levels Tuesday evening across the 
southern waters ahead of an approaching high pressure system.

Outlook /Tuesday Night through Friday/...

Tuesday Night: Winds less than 25 kt. Areas of seas approaching
5 ft. 

Wednesday: Winds less than 25 kt. Seas locally approaching
5 ft. 

Wednesday Night through Thursday Night: Winds less than 25 kt. 

Friday: Winds less than 25 kt. Areas of seas approaching 5 ft.
