.WHAT HAS CHANGED...
No significant changes to the forecast since the last update.

&&

.KEY MESSAGES...

- Unseasonable warmth and dry weather hold through at least mid
  to late week. Maximum temperatures peak in the upper 60s to 
  low and mid 70s potentially putting daily records in jeopardy.

- Unsettled weather with continued warmer temperatures expected
  later this week heading into the weekend, which would feature
  periodic chances for rain.

&&

.DISCUSSION...
KEY MESSAGE 1...Dry with anomalous warmth continuing into mid-week. 
Daily high  in the upper 60s to low 70s, with isolated readings into 
the  mid-70s flirting with daily records.

High confidence in continued dry and warm conditions through late 
week. Mid-level ridge remains dominant across the eastern CONUS, 
with the ridge axis moving over the region through at least 
Wednesday. Deep-layer subsidence combined with 925mb temps in the 
+11C to +14C range will yield an uncharacteristically warm airmass 
through Friday. Dry soil conditions and full solar insolation will 
continue the chance for high temps to overperform vs the NBM/MOS 
consensus. Thus, have bumped high temperatures on Wednesday and 
Thursday in the CT and Merrimack Valleys up 3-5 degrees. Doing so 
yields highs in the mid and even upper 70s across these 
regions. These readings would potentially challenge daily 
maximum temperature records both Wednesday and Thursday. 
Additionally, a SSW return flow will help to increase surface 
dew point temperatures into the 50s and 60s Wednesday night 
through Friday. This results in elevated nocturnal minimums and 
so both high and low maximum temperature records may be 
challenged through the week. More details in the climate section
below. 

KEY MESSAGE 2...Unsettled weather with continued warmer 
temperatures expected later this week heading into the weekend, 
which would feature periodic chances for rain.

A thermal ridge is expected to continue building over southern New 
England towards the midweek timeframe, which will be supportive of 
above-normal temperatures continuing for Wednesday and Thursday this 
week. 925 mb temperatures between 12-16C along with SW to S flow 
will bring the possibility of highs in the upper 60s into the 
low/mid 70s across southern New England Wednesday and Thursday. 
Ensembles have quite high probabilities of highs exceeding 70F 
Wednesday afternoon, and these remain somewhat elevated (up to 90% 
in southern parts of the coastal plain) for Thursday afternoon as 
well. Guidance doesn't indicate much with regards to a return to 
more mild temperatures until the second half of the weekend as the 
ridging shifts off to the east, but that could vary depending on how 
the approaching system evolves and tracks across the region.

Ensembles have continued to show a consensus with regards to the 
return of more unsettled weather for the second half of this week. A 
mid to upper level trough is expected to move in from the west, 
which will help advect in an anomalous moisture plume around 2 to 3 
standard deviations above normal over southern New England. Closer 
to the surface, a frontal system associated with a previously more 
developed low pressure is expected to track across the region, 
bringing good chances for wetting rains towards the end of the week. 
Exact timing is still a bit uncertain, but latest guidance is 
leaning towards onset being Thursday evening at the earliest in 
western MA and CT, then tracking eastward through Friday. Showers 
may even linger into Sunday for parts of the region. Ensemble 
probabilities with regards to totals have not changed much from the 
overnight forecast, with probabilities for 24-hr totals >= 0.5" 
(period ending Saturday morning) generally between 30-70% across 
ensemble suites. Notably, though, the Canadian and ECMWF ensembles 
distribute these probabilities across the majority of southern New 
England as the front tracks from west to east, while the GEFS has a 
more focused footprint of higher probabilities and totals over Cape 
Cod and some of the coastal plain in SE MA. Given the spread in 
guidance, there is still decent uncertainty regarding the 
progression and development of the surface features that would 
really enhance rainfall totals and even introduce the chance for 
some rumbles of thunder.

12z TAF Update...High confidence.

VFR. This will persist through the middle of the week. Mid to

.MARINE...
Forecaster Confidence Levels...

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

Through Wednesday...High confidence.

An upper level ridge of high pressure will keep winds/seas below 
small craft advisory thresholds through the middle of the week. 
Nonetheless...we may have some SW wind gusts of 20+ knots at times 
particularly nearshore during the afternoons. This may result in 
some choppy seas at times...but thinking we should remain below the 
need for headlines. Greatest chance of 20+ knot winds is this 
afternoon across the SE waters.

Outlook /Wednesday through Saturday/...

Wednesday: Winds less than 25 kt. Patchy fog. Local visibility
1 to 3 nm.

Wednesday Night: Winds less than 25 kt. 

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

Thursday Night: Winds less than 25 kt. Seas up to 5 ft. Chance
of rain. 

Friday: Winds less than 25 kt. Seas up to 5 ft. Rain likely,
slight chance of thunderstorms. 

Friday Night: Winds less than 25 kt. Seas up to 5 ft. Rain,
slight chance of thunderstorms. 

Saturday: Winds less than 25 kt. Rough seas up to 9 ft. Rain
likely, slight chance of thunderstorms.

.CLIMATE...
Persistent unseasonable warmth over the next several day will
