.DISCUSSION...

KEY MESSAGE 1...Dry start to the day today with scattered showers
and isolated thunderstorms developing in the afternoon. Near- 
seasonable temperatures. 

Brief period with weak high pressure in place will bring a dry start 
to the day today with a mix of sun and clouds. Temperatures aloft 
warm a few degrees from yesterday allowing temperatures to recover 
back to more seasonable values in the upper 60s and low 70s. Clouds 
increase in the afternoon as the next shortwave approaches. This 
shortwave trough will drop southward bringing a slight uptick in 
moisture to support scattered showers developing in the afternoon. 
The morning sunshine and warmer temperatures should also help build 
marginal instability to support a few brief downpours or an isolate 
weak storm. 

Showers continue early tonight gradually decreasing in coverage 
through the overnight period as the remainder of the system shifts 
across the region. 

KEY MESSAGE 2...Unsettled conditions for the first half of the week 
with periods of isolated to scattered showers.

Another push of cold air gets ushered into the region Monday behind 
the Sunday night's system. This will bring cool day with cooler than 
normal highs in the upper 50s and 60s. Expect warmer temperatures in 
the CT Valley in the mid to upper 60s while onshore flow keeps the 
east coastal areas on the cooler side struggling to get into the low 
60s. A weak trailing piece of shortwave energy drops south during 
the day Monday. Not much moisture to work with, but there is a low 
chance (< 30%) to support isolated/pop-up showers in the afternoon. 

Tuesday, the core of lower 500mb heights shifts east although 
souther New England still remains under a trough aloft. With the 
slight moderation in heights, temperatures aloft follow by warming a 
few degrees from Monday. This should support a more seasonable day 
with high temperatures in the low to mid 70s with local sea breezes. 
Coastal areas may end up a bit cooler in the upper 60s where the sea 
breeze sets up. There are indications across model guidance for 
another weak piece of shortwave energy shifting southward across the 
region resulting in another shot for some pop-up showers in the 
afternoon. 

KEY MESSAGE 3...Confidence decreases in forecast for late-week. More 
likely leaning dry and warm. Still monitoring in potential for a 
coastal system to bring showers late Thursday and Friday. 

Uncertainty grows in the forecast as we head into late-week. 
Ensemble guidance shows a general consensus with an amplified upper 
level trough nudging east into the region. A chunk of solutions 
indicate that a closed low develops at the base of the upper trough 
near the Carolinas then tracking in a north/east Thursday into 
Friday. Ensemble means are currently favoring this closed low to 
track well offshore of the region resulting in dry conditions. 
However, there have been individual solutions across deterministic 
and ensemble guidance that indicate a closer pass to the 40N/70W 
benchmark which may bring showers to the eastern portions of the 
region. If it does end up dry, there is a signal for a strong ridge 
aloft to bring an anomalously warm airmass into the region. This may 
support summer-like temperatures in the low to mid 80s, perhaps 
nearing 90s in the Valleys.

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...

Forecaster Confidence Levels...

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

12z TAF Update...

Today...High Confidence.

Any lingering localized fog patches burn off by 13z.
Otherwise...VFR today outside of scattered showers and an 
isolated t-storm or two expected to develop after 18z especially
across central and eastern MA into RI. Given cold temps 
aloft...a bit of graupel is possible with any of the heavier 
showers too. WNW generally near 10 knots...But brief localized 
sea breezes possible for a time near the immediate coast this 
afternoon.

Tonight...High Confidence. 

Mainly VFR outside any scattered showers and isolated t-storm
risk with the main threat coming to an end by midnight. 
Potential for MVFR ceilings to push in after 10Z for the east 
coast/Cape terminals. This as light NW flow turns N-NE towards
12z Monday and increase to between 8 and 14 knots. 

KBOS...High confidence in TAF. Main concern is after 18z for
scattered showers with the low risk of an isolated t-storm in
the vicinity of the terminal into this evening. Also...a brief
sea breeze possible this afternoon. 

KBDL...High confidence in TAF.

Outlook /Monday through Thursday/...

Monday: Mainly VFR, with local MVFR possible. Slight chance
SHRA.

Monday Night: VFR. 

Tuesday: VFR. Slight chance SHRA.

Tuesday Night through Thursday: VFR.

.MARINE...
Forecaster Confidence Levels...

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

Today and Tonight...High Confidence. 

NW winds continue to decrease across the water early this
morning, less than 25 kts by 12Z. SCAs remain in place for outer
coastal waters for 5-6 ft seas. Cape Cod Bay/Nantucket sound and
Mass Bay falls below 5 ft this morning followed by the norther
outer coastal waters by this evening. Seas stay around 5 ft 
through late tonight for the southern outer coastal waters. 

Outlook /Monday through Thursday/...

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

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

Tuesday through Tuesday Night: Winds less than 25 kt. 

Wednesday through Wednesday Night: Winds less than 25 kt. Seas
locally approaching 5 ft. Slight chance of rain showers. 

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