Synopsis
Widely scattered showers will be possible through tonight, but
the majority of this time period should feature dry weather. A
more potent storm system impacts the region late Thursday into
Friday with numerous showers and a few embedded thunderstorms
that may contain locally heavy rainfall, especially across
northern and western ma. Dry and seasonable weather returns for
the weekend, then more summery weather for early next week with
a risk for a few showers and thunderstorms at times.

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

regional radar shows an area of showers and thunderstorms in
eastern pa and nj lifting ne. High-res models want to bring
this activity into sne before sunrise, while additional widely
scattered showers pop up as deeper moisture works its way into
region. Models do show some mucape, primarily in western new
england, so it's possible we get some isolated storms in that
area. Otherwise expect a muggy night with low clouds and patchy
fog.

Short term 6 am this morning through 6 pm Friday
Thursday Thursday night...

shower chances increase thru Thursday, likely to categorical pops,
with brief locally heavy rainfall possible. Surface low pressure
tracks from the southern great lakes region eastward into new
england. Low pressure drops to 995 mb, atypical for mid-june. System
is moisture-rich with pwats near 2", and is accompanied by a digging
trough axis and divergence aloft from a curved upper level jet. The
better dynamics are expected to be N of our area, where a lingering
frontal boundary will also provide better forcing. Convective
allowing models support this as where the higher QPF is forecast.

However this will need to continue to be monitored.

Within sne, expecting mainly 0.5 to 1.5 inches of rainfall during
thu into Thu night, with locally higher lower amounts possible.

Highest rainfall totals are expected across northern western
ma. Scattered thunderstorms are expected during Thursday
afternoon and evening, which could bring localized heavy
rainfall and minor urban poor drainage flooding.

Winds start off light from the east Thu morning, becoming S se
later in the day. Cloud cover, precipitation and onshore flow
will limit highs to the mid 60s to mid 70s, coolest along the
shoreline and the higher terrain of the east slopes berkshires.

Surface low expected cross thru sne during the overnight, bringing a
cold front thru the area. Pwats remain quite high during this
timeframe, again close to 2", and soundings remain close to moist
adiabatic. Thus we have continued likely to categorical pops for
showers, with scattered to isolated thunderstorms possible thru the
evening hours.

Winds Thu night start out from the S se, then eventually become nw
during the overnight as the low starts to track E of our area.

Surface dewpoints remain high overnight, keeping lows in the low to
mid 60s across most of the region. Far interior higher terrain may
be a bit cooler, in the upper 50s, towards daybreak fri.

Long term Friday night through Wednesday
Highlights...

* showers linger fri, improving from west to east in the afternoon
* dry seasonable this weekend with a warming trend
* warmer temps early next week with the risk for a few showers t-
storms but majority of the time will be dry
details...

Friday...

surface low and attending cold front will be moving off the coast in
the morning, but sharp mid level trough axis and deep moisture plume
is lagging to the west and sweeps through new eng during the day
with comma head likely bringing a period of showers to the region.

Drying moves in from the west in the afternoon so expect improving
conditions and partial sunshine developing in western new eng in the
afternoon. Temps are tricky Fri and may fall into the upper 50s to
lower 60s as showers move through with post frontal northerly winds,
then possibly recover into the 70s in the ct valley in the afternoon
as sunshine develops.

Saturday and Sunday...

deep upper trough from the maritimes to east of new eng Sat with
cyclonic flow will lead to diurnal CU developing and a mix of clouds
and sun. There is a low risk for a brief shower sprinkle in eastern
ma as shortwave energy rotates through. Otherwise, a dry day with
seasonable temps in the 70s, but breezy at times. Then Sunday will
feature more sunshine, less wind and warmer temps as the upper tough
lifts out. Highs should reach upper 70s to lower 80s as 850 mb
temps moderate to 12-14c by late day.

Monday through Wednesday...

upper ridge builds into new eng Mon but is replaced by a broad
trough late Tue into Wed as shortwave energy lifts across SE canada.

Mon looks mostly dry as best instability remains to the west but
can't rule out a shower or t-storm in the west in the afternoon.

Then risk for a few showers t-storms increases Mon night into Tue as
moisture instability increase ahead of approaching shortwave. Risk
of showers may linger into Wed depending on timing of cold front but
this is uncertain.

Overall, warmer temps expected early next week but confidence is not
high in specific temp forecast and it is possible a weak backdoor
front could bring cooler temps. Large differences between GFS and
ecmwf for Tue with GFS showing major heat in the 90s while ECMWF has
boundary to the west with onshore flow and temps in the 60s. While
the ECMWF solution is not the likely scenario, it decreases
confidence in heat potential. Considerable temp differences continue
for Wed with ecwmf remaining on the cool side of the guidance.

thunderstorm could develop Friday afternoon.
