Synopsis
A coastal storm will bring some light rain drizzle and coastal
winds late tonight into Monday, with some light icing just
northwest of the boston to providence corridor. The rain may end
as a bit of snow ice across the interior high terrain of
massachusetts late Monday night into Tuesday morning. Mainly dry
and seasonably chilly weather follows Tuesday afternoon through
Thursday afternoon. A cold front may bring some showers and
briefly milder temperatures Thursday night into Friday. Chillier
weather returns for the start of next weekend.

Near term until 6 am this morning
1 am update...

* risk of light icing just northwest of the boston to providence
corridor toward daybreak
dry air aloft will persist early this morning with deeper
moisture not reaching SE new eng 09-12z. As a result, just some
spotty drizzle or freezing drizzle expected early this morning
and toward daybreak.

Coastal front has slipped past bos and temps have dropped to the
upper 30s. The front will likely remain near or a bit east of
the i-95 corridor into the morning as coastal storm crosses 70w
well south of the benchmark. Temps in the interior are near
freezing and dewpoints in the 20s. So any light precip may allow
enough wet bulb cooling for temps to fall a degree or 2 which
would create problems with any light drizzle that develops.

Risk of some very light icing for the morning commute in the
interior to the i-95 corridor as it only takes a trace to result
in hazardous icy travel.

Short term 6 am this morning through 6 pm Tuesday
Highlights...

* light icing likely across parts of the interior through midday
Monday
* NE wind gusts 35 to 45 mph across CAPE islands Monday, with a
few gusts up to 50 mph across the islands
* minor coastal flooding possible along the eastern mass coast
Monday afternoon
details...

1) interior light icing potential...

with the cold air draining across the interior on n-ne winds,
temps will gradually fall to near or below freezing mainly after
midnight. Best chance for colder temps will occur across the
higher inland terrain, which could see the best shot for light
icing. Still need to monitor the placement of the coastal front
and whether it wavers either farther inland or off the coast
overnight.

As the coastal low tracks a bit further offshore than previously
forecast, could see the cooler temps remain further inland, and
the coastal front may not make too much further inroads. This
will be something to monitor closely. In this case, there is
still the potential for some light icing as far east as the
merrimack valley, as well as portions of the ct valley.

Winter weather advisory remains in place from the berkshires to
the merrimack valley. Any icing will be light with amounts a
trace to one tenth of an inch. Temps will be warming above
freezing by midday Monday, so any freezing precip will change
over to all rain.

2) strong wind potential along the coast...

ne low level jet still forecast to reach to around 50 kt as it
slowly lifts north across coastal areas. Peak of strong winds
will move in during the day on Monday, with gusts to 35 to 45
mph over the CAPE islands late tonight and Monday. There is
still the potential to see gusts up to 50 mph on nantucket and
martha's vineyard.

With this in mind, have extended the wind advisory to include
cape cod, and will see the strongest winds on Monday.

Fortunately, given most leaves are off the trees these wind
speeds should not cause too many issues other than a few downed
tree limbs and isolated power outages.

3) minor coastal flooding potential:
see tides coastal flooding section below.

Long term Tuesday night through Sunday
Highlights...

* showers Mon night early Tue am may end as a bit of snow ice
mainly across the berks and northern worcester hills
* mainly dry seasonably chilly the rest of Tue through thu
afternoon
* milder Thu night into Fri with some showers possible but not
expecting the entire period to be a washout
* chillier temperatures return by the start of next weekend
details...

Monday night into Tuesday morning...

coastal low will lift northeast towards the canadian maritimes
mon night. However, vigorous upper level disturbance will lag
behind and cross the region Mon night into Tue morning. This
should result in showers increasing again in areal coverage
during the late evening and overnight hours. Model cross
sections indicate that thermal profiles will be mild enough for
just liquid precipitation across most of the region. It may
become just cold enough for rain to change to snow ice mainly
across the east slopes of the berks and northern worcester hills
before precipitation ends by late morning tue. Accums of a
coating to 2 inches seem reasonable right now, so some slippery
travel is possible for the high terrain of the berks northern
worcester hills.

Tuesday afternoon through Thursday afternoon...

mainly dry and seasonably chilly weather is on tap tue
afternoon through Thu afternoon with a west to northwest flow.

High temps will mainly be in the 40s. The chilliest day of the
week looks to be wed, behind the passage of a cold front.

Thursday night and Friday...

low pressure tracking well to our northwest, may bring some
showers to the region sometime Thu night and or Fri but not
expecting a washout over this time period. Somewhat milder
temps return Fri ahead of the front, so decent shot many
locations see highs in the 50s.

Saturday and Sunday...

mainly dry and chilly temperatures return behind the cold front
on sat. Will then need to watch a low pressure system that may
approach from the south late Sat night sun. If it gets close
enough may bring some precipitation to the region, but that is
uncertain at this time.

Marine
Short term through Tuesday ... Moderate confidence.

Gale warnings continue for all waters. Expect NE winds to peak
late tonight through most of Monday. Wind gusts are forecast to
reach 35 to 45 kt with a few higher gusts possible. Seas will
build up to 15 ft across the eastern outer waters. Vsbys
reduced in rain and fog late tonight and Monday.

Outlook Tuesday night through Friday ...

Monday night: moderate risk for gale force winds with gusts up
to 35 kt. Rough seas up to 17 ft. Chance of rain showers, patchy
fog.

gusts up to 30 kt. Rough seas up to 11 ft. Slight chance of rain
showers.

Tuesday night: winds less than 25 kt. Seas up to 5 ft.

Wednesday: low risk for small craft advisory winds with gusts
up to 25 kt. Seas up to 5 ft. Slight chance of rain showers.

Wednesday night: moderate risk for small craft advisory winds
with gusts up to 30 kt. Areas of rough seas.

Thursday: low risk for small craft advisory winds with gusts up
to 25 kt. Local rough seas.

Thursday night: moderate risk for small craft advisory winds
with areas of gusts up to 30 kt. Areas of seas approaching 5 ft.

Chance of rain showers.

Friday: low risk for gale force winds with gusts up to 35 kt.

Areas of rough seas. Chance of rain showers.

Tides coastal flooding
Continue to forecast a storm surge of 1.5 to 2 ft during the
high tide Monday afternoon. Low level jet is expected to arrive
close the same time as the mid afternoon high tide.

Astronomical high tide at boston is 10.3 ft mllw, and 3.7 ft
mllw at nantucket harbor. This will bring pockets of minor
coastal flooding to much of the eastern mass coast. Seas
offshore will build up to 15 ft, which will add to the impact
along the coast and may bring minor beach erosion.

A coastal flood advisory remains in effect for the eastern mass
coast including nantucket. However, the winds and storm surge
will not be high enough to cause a significant coastal flood
event.
