Synopsis
A taste of summertime heat this afternoon with a low risk for
an isolated late afternoon thunderstorm south of the pike. A
cold front moves south of the coast tonight followed by high
pressure building in through Monday, then shifting off the coast
early Tuesday. A few weak lows will move along a wavering front
across the region late Tuesday into Thursday, bringing the
threat for showers. Milder temperatures move in during Thursday
ahead of an approaching cold front, with the threat for more
showers and isolated thunderstorms. The front exits during
Friday, with dry and seasonable conditions to start next
weekend.

Near term until 6 pm this evening
Clouds from ovrenight are moving off CAPE cod and islands and
should complete the clearing by midday. A second area of clouds
is moving southeast from the berkshires. Mostly clear in between
with developing cumulus. Temperatures range from the upper 60s
to mid 70s.

Morning soundings show mixing potential to 770 mb or deeper,
although albany sounding has two inversions to break to achieve
the deep mixing. Soundings are dry above 750 mb, so any cloud
layers that do develop should be shallow. Do note the albany
sounding shows an 8.3c km mid level lapse rate. Temps in the
mixed layer tap aloft temps equiv to 14-16c at 850 mb. Mixing to
750 mb would tap an equiv of 18c. Winds in the mixed layer are
northwest around 30 kt, so expect afternoon gusts to this speed.

We continue to monitor favorable sbcape, projected around 1000
j kg mid to late afternoon, superposed on observed dry air.

Convective parameters that rely on lapse rate are signalling
potential convection, while those that rely at least partly on
moisture are quite pessimistic for any convective development.

There is a front coming through during the afternoon evening
which could generate low-level convergence with surface layer
dew points in the mid to upper 50s. Best chance for any
convection would be across parts of eastern ma, ri, eastern ct.

We will continue to show slight chance pops for thunder over
this area mid to late afternoon. As noted earlier today, the
chance is small but non-zero.

Short term 6 pm this evening through 6 pm Monday
Tonight...

weak front moves south of the coast with dry airmass and light
northerly flow. With clear skies, lows will drop back into the
50s.

Monday...

weak high pres in control will result in plenty of sunshine.

Cooler airmass but still warm away from the coast. High should
reach well into 70s, near 80 ct valley, but upper 60s along the
immediate coast, especially eastern ma where sea breezes
develop. A cold front will be dropping south from northern new
eng during the afternoon and a few showers are possible along
the boundary but this should remain to the north. The front
drops south across sne Mon evening.

Long term Monday night through Saturday
Highlights...

* mainly dry conditions Monday night
* wavering front lingers Tuesday through Wednesday night with
areas of showers and patchy nighttime fog
* cold front approaches Thu thu night bringing mild
temperatures with showers and isolated thunderstorms
* rain exits Friday, then mainly dry, seasonable conditions
early next weekend
overview...

the progressive, active weather pattern across the northeast
looks to continue through most of not during the entire long
term period. Subtropical ridging remains across the southern
u.S., with general long wave ridging remains across the western
third of the country. Noting a continued nearly zonal mid level
steering wind flow across the northeast, bringing a series of
short waves from the central mississippi valley across the great
lakes to the region.

So, will see periods of showers with mainly near to somewhat
below temperatures through around Wednesday night. The wavering
front channeling these lows may lift far enough north for a
brief break, before a cold front moves E out of the ohio
valley southern great lakes during Thursday. This may bring
milder temperatures and more instability, so may see isolated
embedded thunderstorms late Thu thu night prior to frontal
passage.

Medium range models continue signal generally drier, seasonal
conditions for the start of june.

Details...

Monday night...

should see dry but cool conditions Monday evening as high
pressure moves off the S coast. With the fast flow aloft, clouds
will increase and a few showers may push into central and
western areas after midnight as a warm front approaches.

Tuesday through Thursday...

a mainly zonal steering flow from north central plains eastward
to the northeast will keep mid level shortwaves and associated
surface lows moving across the region. GEFS ensembles signaling
possible pwat plume moving across, with 1-2 sd above normal
precip, possibly up to 3 sd above normal by late Thursday.

Each system will bring a chance for showers, though there may
be a better chance from around midday Tuesday into Wednesday
morning. Current forecast suggests some locally heavy rainfall
may move in with this system, especially across the ct valley
and central areas. QPF amounts may range from 0.5 inches to 1
inch of precip there.

May see a brief break around Wednesday night, then another shot
moves in by around midday Thursday. Temps may warm up during
Thursday as a warm front lifts n. Highs may reach the lower-mid
80s. This will help increase the instability factor ahead of the
approaching cold front, with k indices in the lower 30s, slis
around zero to -1 and tq values in the upper teens. Have
mentioned isolated thunder during this portion of the forecast.

Friday and Saturday...

h5 short wave and surface cold front crosses the region Friday,
with leftover showers pushing offshore by around midday. Some
models try to have some spotty precip lingering across central
and eastern areas during the day, but should be mainly dry and
cooler as winds shift to w-nw.

Dry, nearly zonal mid level flow sets up across most of the
northern tier by early Saturday. Ridging looks to set up across
the northeast. So, at this point, looks like generally dry and
seasonal conditions for the start of meteorological summer on
Saturday.
