.KEY MESSAGES...

- Widespread rain continues this evening and overnight with some
  urban and poor drainage flooding possible. Rain will be heavy
  at times southeast MA and RI where flood risk is greatest. 

- Cooler and drier conditions arrive next week, though it could
  turn unsettled once more towards the second half of the week.

&&

.DISCUSSION...
KEY MESSAGE 1...Widespread rain gradually ends this morning. Rain
will be heavy at times southeast MA and RI, where flood risk is
greatest. Another round of lighter showers this afternoon into
Sunday.

Broad low pressure along a stalled front across eastern MA and
RI will slowly move offshore this afternoon and evening. This 
low pressure should finally reach Downeast Maine and Nova Scotia
around daybreak Sunday.

While this means the widespread rainfall should be offshore by
this afternoon, we will still have to contend with a rather
potent mid level low. This low should pass overhead tonight. The
colder air aloft will result in increased lapse rates, which in
turn should generate some showers later today and tonight. 
These showers will be much lighter in intensity. The greatest 
coverage of showers should be towards northern MA. 

Above normal temperatures continue yet again today, but will be
trending closer to normal. Expecting only slightly above normal
temperatures for Sunday. 

KEY MESSAGE 2...Cooler and drier conditions arrive next week,
though it could turn unsettled once more towards the second 
half of the week.

Colder air aloft continues to shift into southern New England
for the start of next week as yet another upper level trough 
tracks into the region. This is a bit more notable at 850 mb and
500 mb, where temperatures fall to just below 0C and to around 
- 24C at those respective levels. With cooler air aloft and a 
passing shortwave just to our north, we could see some showers 
around Monday. 925 mb temperatures fall to around 2-4C by Monday
night, supporting lows falling further into the 30s and low 
40s, with highs Tuesday and the start of the week generally in 
the 50s to low 60s. Cooler nights will persist through the week.

NAEFS and other ensemble guidance indicate no significant
deviations from the climatological percentiles for temperatures 
or moisture for this coming week, though did note 90th
percentile zonal winds aloft Monday into Wednesday just to the
south of the region. Persistent westerly flow with notably
breezy conditions Monday and Tuesday is expected. Winds
generally stay westerly through much of the week, given the
series of fronts expected to move through the region. With the
drier conditions (PWATS to around 0.5" and less and dew points 
back in the 30s and 40s) at the surface, not much in the way of 
precipitation is expected with these frontal passages; just 
cooler air. Occasional cloudiness is expected at most with 
passing moist air aloft.

Towards the second half of next week, guidance has started to
pick up on the possible development of another low pressure
originating from just to the south of the region along/just off 
the mid- Atlantic coast. This looks to be driven by the approach
of an upper level shortwave tracking from Canada southeast into
the mid-Atlantic region. With this possible system, we could see 
the return of more unsettled conditions for the second half of 
the week.

Through Sunday...High confidence on trends, lower confidence on
exact timing and details.

Low pressure and a cold front finally move east across the 
waters tonight into Sunday. Moderate to heavy rainfall possible
this morning with restricted visibility less than 1 NM at times.
Rough seas subside early this morning. Gusty W to NW winds 
develop tonight into Sunday, which will lead to another round of
rough seas, mainly across the outer coastal waters. While there
will likely be several hours of a lull in Small Craft Advisory 
conditions, may just extend it across the outer RI coastal 
waters for messaging. Rough seas and gusty winds should return 
by this evening there. Elsewhere, Small Craft Advisory 
conditions develop tonight and continue through at least Sunday.

Outlook /Sunday Night through Wednesday/...

Sunday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Areas of rough seas. 

Monday through Monday Night: Moderate risk for Small Craft
Advisory winds with local gusts up to 30 kt. Rough seas up to
