.WHAT HAS CHANGED...
Expanded the Flood Watch to include Windham, Southern Worcester, 
Suffolk, and Suffolk Counties. Monitoring a very low chance for 
waterspouts and a weak tornado across the south coast. The risk for 
any severe thunderstorms is dwarfed by the hydrologic risk, however.

&&

.KEY MESSAGES...

- Confidence continues for a period of torrential and a risk of flooding
  across much of Rhode Island and southeast Massachusetts. 
 

- High pressure in control next week brings generally quiet
  weather. Brief bout of summer warmth and humidity expected
  Wed-Fri.

.DISCUSSION...
KEY MESSAGE 1...Confidence continues for a period of torrential and 
a risk of flooding across much of Rhode Island and southeast 
Massachusetts. 

Main forecast focus for the next 48 hours continues to be on a 
shortwave and warm front later tonight through much of the day on 
Sunday. Aloft, the area will find itself in the right entrance 
region of a 80-90 kt jet by 12z Sunday morning. So, synoptically, 
there are plenty of jet and frontal dynamics at play to allow for a 
heavy rain event. The thermodynamic environment certainly isn't 
lacking either, with model soundings showing PWATs climbing to >2" 
which is near the 99th percentile of climatology for September 13th. 
These highly anomalous PWATs pair with a nearly saturated 
atmospheric column and warm cloud heights of 12-14kft and allow for 
efficient rainfall processes and areas of torrential rain. Taking 
these conditions into account it makes sense that the 12z HREF shows 
a 40-55% chance for 3 hour rainfall amounts to exceed flash flood 
guidance covering an area from eastern Connecticut to Rhode Island 
and SE Massachusetts. Additionally, there is still a strong (55-70%) 
chance for 6-24 HR precipitation values to exceed the 5 year ARI and 
a moderate (25-40%) chance of exceeding the 10 year ARI. The 
greatest concern for areas of flash flooding is across the urban 
corridor from Providence to interior SE MA. Still some uncertainty 
with regards to the exact placement of the heaviest rain it will be 
contingent upon the placement of a mesoscale low. Subtle 
differences in deterministic guidance have this band as far south as 
the south coast and as far north as northern Massachusetts. Think 
the HREF and RRFS handle these differences best by centering 
the highest rainfall totals along the I-95 corridor. 

Given the uncertainty and the N jog in guidance, opted to expand the 
Flood Watch to include Windham county in eastern Connecticut, 
southern Worcester County, Norfolk county, and Suffolk County 
including Boston. Elsewhere, a widespread 0.50" to 1.50" expected 
across much of our region Within the watch there will likely be 
localized narrow bands of 2"-4" of rain possible inside 3 hours. The 
narrow but intense area of rainfall likely comes to an end from west 
to east between 2 and 5 pm.

On a final note, while the main threat is areas of flash flooding, 
there is a low albeit non-zero chance for isolated severe weather 
across coastal RI and MA. CAMs show a narrow area of MLCAPE 
approaching 300-500 J/kg across coastal areas. Paired with 0-1km 
shear of ~20kts and curved hodographs there is a very low chance for 
a spin up or a waterspout as the mesolow passes late tomorrow 
morning into the afternoon. What's lacking is adequate instability 
or lapse rates for deeper convection but worth keeping an eye on. 


KEY MESSAGE 1...High pressure in control next week brings generally 
quiet weather. Brief bout of summer warmth and humidity expected Wed-
Fri.

The start of the new work week starts with some lingering showers as 
the cold front makes its way offshore. Rain comes to an end after 
sunrise for western MA/CT while showers linger into the early-mid 
afternoon across eastern MA/RI. Eventually dry NW post frontal flow 
advects 40-50F dewpoints overhead which combined with highs in the 
low to mid 70s Mon and Tue will make for a comfortable and 
seasonable first half of the week. This, as high pressure is in 
control at the surface through much of the week keeping us dry. As 
the high shifts offshore Wednesday flow turns southerly bringing the 
return of more summer-like temperatures and dewpoints in the upper 
70s and mid 60s respectively. Uncertainty increases with regard to 
the forecast for late week next weekend. Zonal mid level flow 
continues into the weekend with potential for a low to cross 
somewhere in the vicinity of southern New England; whether that 
stays to our north or goes overhead is uncertain, but generally 
looking at a better shot of unsettled weather late Thursday
onward.

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
Forecaster Confidence Levels...

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

00Z TAF Update...

Tonight...High confidence. 

VFR. S winds. Ceilings remain VFR most of the night, though 
area gradually lowering to low- end VFR between 08-12z. 

Sunday...High confidence in trends, moderate confidence in timing. 

Widespread showers and potentially a few embedded thunderstorms will 
overspread the region from west to east roughly 09z-14z Sunday 
morning. This will result in low-end MVFR to IFR conditions 
developing with even brief LIFR conditions in narrow bands of 
torrential rainfall. The bulk of the heaviest showers should be 
exiting the southeast New England coast by 22z/23z. Winds will be 
light from a S-SE direction. With eastern coastal MA going E. There 
also may be a period of LLWS. 

Sunday Night...High confidence.

Low-end VFR to MVFR ceilings. Wind shift to the NW behind the front. 
 
KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Monday through Thursday/...

Monday through Monday Night: VFR. Breezy. 

Tuesday through Thursday: VFR.

.MARINE...
Forecaster Confidence Levels...

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

Today through Sunday...High confidence.

A warm front than approaches and crosses the waters on Sunday. 
Surface gradient should remain weak enough to keep winds/seas 
below small craft advisory thresholds through Sunday. 
However...the main concern for mariners will be heavy showers 
and potentially a few embedded thunderstorms on Sunday with 
reduced visibility. There is a very low chance for a water spout
or two mainly across the near-shore waters along the S coast. 

Outlook /Monday through Thursday/...

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

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

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

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

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