.WHAT HAS CHANGED...
Increased probability for 1-2" of rainfall possible Thu into
Fri.

&&

.KEY MESSAGES...

- Widespread rainfall Thu into Fri, with 1-2" possible in spots.

- Cool weather Friday, gives way to a pattern change this
  weekend into next week, accompanied by unseasonable warmth.

&&

.DISCUSSION...
KEY MESSAGE 1...Appreciable rainfall Thursday, lingering into Fri.

High amplitude pattern Thu and Fri, yields roughly a 48 hr period of 
wet weather. This high amplitude pattern contributes to a slower 
arrival time of the rainfall, with much of this afternoon and 
evening dry across MA/RI/CT. Just expecting some warm frontal 
showers this morning and mainly confined to CT and northern MA. It 
will become breezy this afternoon and continuing into early this 
evening, with south winds gusting up to 20-30 mph at times. Cloud 
cover and southerly winds off the cool ocean will cap highs this 
afternoon to the low to mid 60s, about 5 degs cooler than normal. 

Potent short wave streaming across the Great Lakes Tue night, digs 
southeast and evolves into a high amplitude vertically closed cool 
season low Thu, that slowly tracks just south of New England Fri. 
This yields deep layer Atlantic moisture advection into SNE, with 
PWATs greater than 1 inch Thu and Thu evening, along with strong 
synoptic scale forcing for ascent. This will result in widespread 
rain Thu and Thu night, then transitioning to lighter rain/drizzle 
Fri, as dry slot overspreads the region. Rain will be moderate to 
heavy at times, given strength and persistence of low level S-SE jet 
(possible upslope enhancement), combined with some elevated 
instability. Widespread rainfall of 0.5-1.0 inches, however up to 2 
inches possible per hi res guid, ensembles and AI models. However, 
given rainfall will be spread out over 2 days, not expecting any 
flooding, more of a beneficial rainfall, with typical nuisance 
street/highway flooding possible. 

KEY MESSAGE 2...Cool weather Friday, gives way to a pattern change 
this weekend into next week, accompanied by unseasonable warmth.

Departing vertically closed low and associated cloud cover, spotty 
light rain/drizzle (especially Fri AM) and cool NE flow (only +6C at 
925 mb), likely keeps highs in the 50s across the area Fri, with 
coolest temps in eastern MA. Normal high this time of year is 65-70. 
Then over the weekend and into next week, a pattern change evolves 
with the northern stream jet deamplifying and giving way to the 
subtropical ridge emerging and building up along the east coast.

Ensembles indicate high probabilities for temps well into the 
mid/upper 70s Saturday and continuing to warm into the low and mid 
80s Sunday! Possibly not quite as warm Monday, especially in eastern 
MA, if a backdoor cold front makes it this far south. Otherwise, the 
unseasonably warm weather continues early next week and likely peaks 
Tue, with highs possibly as warm as 85-90, as some guidance streams 
+23C/+24C airmass at 925 mb across SNE! It will be relatively dry 
airmass/low humidity, with dew pts in the 50s, possibly rising into 
the low 60s briefly Tue.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
Forecaster Confidence Levels...

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

06Z TAF Update:

Today...High confidence.

VFR. Light rain showers possible 10z-16z across CT into northern MA. 
Otherwise dry weather prevails. Light SW winds early this morning, 
become south late morning and increase 15-20 kt this afternoon with 
gusts up to 30 kt possible at times. 

Tonight...high confidence. 

VFR and dry this evening, then MVFR/IFR cigs after 04z from west to 
east, although remaining mainly dry. As surface winds slacken, 
marginal LLWS possible given modest low level SW jet of 40 kt.  

Thursday...high confidence on trends but some uncertainty on exact 
timing of details. 

MVFR/IFR with periods of rain, moderate to heavy at times. 20-25% 
probability of -TSRA in embedded heavier showers. Marginal LLWS 
possible in the morning, as 40-45 kt low level S-SE jet moves across 
the area, then offshore during the afternoon. 

KBOS...High confidence.

KBDL...High confidence.

Outlook /Thursday Night through Sunday/...

Thursday Night: MVFR/IFR conditions possible. SHRA likely,
slight chance TSRA.

Friday: Mainly VFR, with areas IFR possible. SHRA likely.

Friday Night: VFR. 

Saturday through Sunday: VFR. Breezy.

.MARINE...
Forecaster Confidence Levels...

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

2 AM update...

Today through Thursday...High confidence.

Strengthening low level SW jet moves across SNE today, with light SW 
early this morning, becoming south and increasing to 20-25 kt this 
afternoon, except 25-30 kt in gusts near shore. Hence, SCA remains 
posted. Other than a spot morning shower across northern MA waters, 
dry weather and good vsby prevail today. South winds slacken tonight 
with mainly dry weather. Rough conditions Thu, with S-SE winds 20-25 
kt in the morning, then slacken in the afternoon and become east as 
low pressure tracks south of New England. This low will bring 
widespread rain to region Thu, moderate to heavy at times with 
reduced vsby.  

Outlook /Thursday Night through Sunday/...

Thursday Night: Winds less than 25 kt. Areas of seas
approaching 5 ft. Rain showers likely, slight chance of
thunderstorms. 

Friday: Winds less than 25 kt. Seas up to 5 ft. Chance of rain
showers. 

Friday Night: Winds less than 25 kt. Seas up to 5 ft. 

Saturday: Low risk for Small Craft Advisory winds with gusts up
to 25 kt. Seas up to 5 ft. 

Saturday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Areas of seas approaching 5 ft. 

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