.SYNOPSIS...
Lingering rain will move out of the region, and a cold front 
then ushers in a much cooler airmass tonight. Cloudy, cool, and 
blustery conditions on Sunday. High pressure returns with dry 
conditions for Monday and Tuesday, along with mild to warm 
temperatures. A cold front moves across the region on Wednesday 
with a few showers possible late Tuesday night into early 
Wednesday morning. Seasonable temperatures to end the week with 
the next chance for rain by Friday.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
Key Messages:

* Drying out with dropping temperatures and gusty winds with frontal 
  passage tonight

Any lingering rain will exit the region tonight around midnight
and a cold front will progress through, which will also help 
clear some of today's cloud cover. Gusty west winds to around 
25 knots will be possible. Drier conditions take hold as this 
cooler and drier airmass moves in; dewpoints expected to fall 
from the 50s and 60s down to the 30s and 40s, and PWATs decrease
down to around 0.5". Lows tonight expected to be in the low 40s
across the interior, with mid 40s for much of the coastal plain
into the Cape and Islands.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
Key Messages:

* Cool and blustery before winds diminish overnight

Clouds return for Sunday due to the cyclonic flow aloft from a 
trough sitting over the region. Winds shift more NW as the day goes 
on. CAA will continue to promote the mixing of winds aloft down to 
the surface, fueling gusts to 35 kt in the highest elevations. Most 
guidance is indicating that the highest winds are possible in 
the afternoon to evening hours when the core of the 50-60 kt 
jet will be over much of southern New England as the trough 
continues to move east. However, the mixing of the strongest 
winds may be cut off as the jet decouples in the evening hours, 
so held off on any wind headlines for the time being. Clear
conditions make a return Sunday night as high pressure begins to
move in after the low exits. Highs Sunday are expected to be in
the 50s, and lows Sunday night should be in the 40s.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
Key Messages:

* Much warmer with dry conditions Monday and Tuesday. A few showers 
  are possible Tuesday night into Wednesday morning ahead of an 
  approaching cold front. 

* Near seasonable temperatures Thursday and Friday. While Thursday is 
  likely dry, rain chances return for Friday. 

High pressure moves off the Mid Atlantic coast early neat week, but 
extends far enough north into New England to maintain dry weather 
through Tuesday. Our region will also be on the warmer side of this 
high pressure with increasing southwest winds, especially Tuesday.

A low pressure moving across eastern Canada should push its cold 
front across southern New England some time Tuesday night into 
Wednesday morning. This will mean a chance for showers during this 
time.

High pressure briefly returns Thursday with dry weather, but this 
time its positioning will lead to lower temperatures. Another low 
pressure moving across eastern Canada should send another cold front 
our way late next week. Thus, there is a risk for more showers late 
next week into next weekend.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

18Z TAF Update:

Rest of Today: Moderate confidence. 

Widespread MVFR/IFR in bands of steady moderate rain, most of which
has started to move offshore. More rain and continued IFR 
conditions are moving through the region at this time, which is 
expected to continue through the rest of today. Possible SCT 
SHRA/TS near/west of ORH after 20z, although development and 
strength of any TS would depend on how quickly we see any breaks
in OVC. If we do see any storms, they would likely be weakening
as they move east of ORH. Occasional rumbles of thunder also 
possible south of the Cape. S/SW winds around 10-15 kt with 
occasional gusts up to upper 20-kt range.

Tonight: High confidence. 

Improvement toward SCT-BKN VFR with cold frontal passage, 
though some MVFR bases may develop overnight in western 
airports. Winds become W/WNW around 10-15 kt with gusts 25 kt 
(up to 30 kt high terrain).

Sunday through Sunday Night: High confidence. 

VFR. NW winds 10-15 kts. Gusts to 30-35 kt possible across the
region during the afternoon/evening hours, dropping off
overnight.
 
KBOS TAF...Moderate confidence in timing.

Scattered RA possible over the next few hours, ending around 02z.
Cigs improving to borderline VFR levels overnight. Gusty winds 
continue through tonight with the cold frontal passage.

KBDL TAF...Moderate confidence in TAF.

Timing for lifting of cigs dependent on frontal passage.
Improvement to MVFR possible around 21z, but may be later.
Isolated TS could be possible this evening.

Outlook /Monday through Thursday/...

Monday: VFR. Breezy. 

Monday Night: VFR. 

Tuesday: VFR. Breezy. 

Tuesday Night: VFR. Breezy. Slight chance SHRA.

Wednesday: VFR. Breezy.

and reduced visibilities expected until a sharp frontal passage 
this evening, bringing a windshift to W/NW around 15-25 kt. 
Sunday NW winds will gust 20 to 25 kts with seas of 3-6 ft.
Small Craft Advisory conditions expected to continue through
Sunday night across the eastern waters into Nantucket Sound and
Cape Cod Bay, with wind gusts to 25 kt and higher possible. Seas
Sunday night ranging from 4-6 ft.
