Synopsis
A few showers are possible late tonight into early Thursday as a warm
front approaches. Showers and scattered thunderstorms late Thursday
into Thursday night ahead of a sweeping cold front. A bit windy on
Friday, especially across CAPE cod and nantucket as low pressure
moves east of the canadian maritimes. Much of Saturday looks dry with
pleasant temperatures, but a fast moving disturbance will probably
bring a period of showers late Saturday into early Sunday. The rest
of Sunday into memorial day looks to be mainly dry, but an approaching
warm front may bring some showers by Tuesday.

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

a few showers from eastern ny approaching western new eng early
this morning, with a more concentrated area of showers and
embedded thunder moving eastward from NE pa. This activity assocd
with the leading edge of higher theta-e air with the mid level
warm front. Bulk of showers will slide to the SW but a few
light showers will move into western ma and northern ct through
daybreak.

Short term 6 am this morning through 6 pm Friday
4 pm update ...

some concern given faster timing of the sweeping cold front, perhaps
destabilization over SW new england prior to that'll be enough to
break the cap along with lift preceding the sweeping cold front. 15z
sref has extended probabilities further into S new england across
ct. Perhaps an artifact of a tongue of higher thermal-instability
and sub-tropical moisture driving N into the hudson valley along
which the cold front will intersect and invigorate multi-cellular
clusters into a squall-line as the 12z NAM nest suggests. Figure
we'll have to evaluate the morning environment with early onset
over-running and light shower activity. See how the cloud deck
evolves and if there are any breaks into the daylight hours. From
there an analysis on the mesoscale environment and convective
parameters. Still confidence that much of S new england will still
see widespread showers with embedded heavier elements, rumbles of
thunder, and gusty winds.

Thursday into Thursday night ...

late afternoon into evening widespread showers with embedded heavier
showers, possible thunderstorms. Confident heavy rain, however lower
confidence with regards to strong to severe weather, particularly
strong to damaging winds and the possibility of a tornado, albeit a
low risk.

Synoptically, n-conus low occlusion ejecting E with attendant h3 jet
streak. Preceding warm front, broadscale 295-300k surface isentropic
ascent, expect scattered morning showers along a convergent nose of
a h8-9 low-level jet with increasing thetae. Clouds linger with high
pressure se, subsequent surface onshore S flow beneath a h9-8 warm
nose with h85 temperatures +14c prior to a sweeping cold front over
s new england around midnight overnight. Big question is whether we
can destabilize over S new england beforehand. Surface low ejecting
over N new england around evening beneath the left front quadrant of
a parent h3 jet streak. Potent h5 vortmax digs across new england as
a W jet throughout the column races E with drier air on the backside
of the aforementioned trailing cold front.

Mesoscale, again, big question is whether we can destabilize, more
so if temperatures warm into the 70s. Clouds, capped by a warm-nose
around h9, and maritime onshore s-flow will limit the environmental
potential along with the late-day into evening event. Noting strong
w shear and low-level helicity, however weak instability in an over-
all saturated moist-adiabatic, convectively unstable environment on
the order of 500 j kg as the cold front sweeps through. Convective
indices met or exceeded in tandem. And with the strong, dry W jet
that looks to impinge rearward of the cold front, its a question as
to whether synoptic influences will erode storm-top development or
enhancement.

Agree with SPC outlook in limiting the strong to severe potential to
the e. Confidence on widespread showers with embedded heavier rain,
some rumbles of thunder. Not ruling out the potential for a strong,
perhaps even a severe thunderstorm. Noting the environment above,
any severe weather threats would mainly be strong to damaging winds
with the very low risk of a tornado. Freezing levels to 10 kft and
precipitable waters to 1.5 inches with both synoptic and convective
support, will also have to watch for heavy rainers and localized
flooding.

Final note, storm attributes from href along with severe parameters
and probabilities from SREF as well as cips analogs not only are
pushing the system through faster per dprog dt but also put the
highest confidence on outcomes SW of our area. SPC has shifted their
d2 outlook accordingly. If anywhere in S new england where there is
the potential for strong to severe weather, seemingly it would be
across W new england into the ct river valley.

Clearing out and drying out overnight with breezy W NW winds that'll
follow. Given the midnight timing, not expecting lows to drop down
significantly, will hold in the 50s.

Long term Friday night through Wednesday
Highlights...

* a bit windy on Fri with perhaps a couple of showers near the coast
* pleasant temperatures Sat with dry weather most of the day
* a period of showers likely sometime late Sat into early sun
probably followed by a mainly dry warm Sun afternoon
* memorial day looks mainly dry with nice temperatures
* a period of showers Tue with a warm front might be followed by
rather warm temperatures by wed
details...

Friday...

amplifying shortwave east of northern new england coupled with a
decent north to northwest LLJ should result in a breezy to windy
Friday. The majority of the day should be dry, but a few showers
may develop along the coast as the flow turns nne. Overall, expect
northwest wind gusts of 25 to 35 mph, but a bit stronger on the
cape nantucket as the flow turns northerly. High temperatures should
mainly be in the upper 60s to the lower 70s. It will be cooler
across the outer-cape nantucket.

Saturday...

as the shortwave departs, rising height fields will result in milder
temperatures. Highs should recover well into the 70s away from any
localized sea breezes on the coast. We may see showers arrive
across interior ma late in the day ahead of the next shortwave, but
overall think much of the day ends up dry.

Saturday night and Sunday...

the shortwave should cross the region Sat night into early sun,
probably resulting in a period of showers. Things could certainly
change in this time range, but appears the bulk of the activity
might be over by Sun afternoon. In fact, westerly flow and a
relatively mild start may push highs well up into the 70s to the
lower 80s.

Memorial day through Wednesday...

a ridge of high pressure may result in mainly a dry memorial day
with pleasant temperatures. An approaching warm front may bring
some showers tue, followed by the potential for mainly dry warm
conditions by wed. Of course this is a long way out, so
certainly subject to change.
