Synopsis
Isolated showers in and around southern new england but even
these should diminish this evening. A cold front swings across
the region early tonight. High pressure then builds over new
england for Monday and Monday night with dry, seasonable
weather. 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 early
Friday, with dry and seasonable conditions to start next
weekend.

Near term until 6 am Monday morning
950 pm update...

isolated showers have developed on the weak boundary along the
south coast where mucapes around 500 j kg. The hi-res cams were
showing the potential for convection on the south coast this
evening with focus shifting south of the coast as the front
moves offshore. Dry conditions expected overnight with gradual
clearing from north to south. Temps still in the 70s across much
of sne but with clearing skies and light winds, lows will fall
back into the mid 50s to lower 60s, but probably not below 65
in bos where it was still 81 at 10 pm.

Short term 6 am Monday morning through Monday night
High pressure in control Monday and Monday night. Some signs of
a weak front trying to shift south through our area in the
afternoon. Limited low level convergence, but in an area of
general subsidence. Limited moisture and lots of dry air above
800 mb, so any trend to form showers will be fighting a
difficult battle.

The center of the high will pass to our north, making it easier
for light winds to turn from the northeast and southeast during
the day. So in addition to plenty of sunshine, expect sea
breezes in the usual spots along the coast. Inland, mixing is
expected to reach to 800 mb, tapping temps equiv to 8-10c at 850
mb. This suggests MAX temps in the mid to upper 70s inland,
with cooler temps at the shoreline.

Dry weather continues Monday night as the high pressure slowly
moves offshore. Increasing cloud level moisture will mean
increasing clouds overnight. But dry air lingers in the surface
layer through 12z Tuesday, so any showers will have a difficult
time moving in. At best, a couple could reach the ct valley
toward morning.

Long term Tuesday through Sunday
Highlights...

* turning cooler Tuesday with rain showers
* a front lingers across the region Wed and Thu with unsettled
conditions and warming temperatures
* 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...

progressive pattern continues through the end of the workweek with
several rounds of rain tues-fri and brief breaks in between. The
persistent subtropical ridge bringing record heat to the southeast
holds on through mid-late week which serves to direct several
shortwaves over top of ridge into southern new england. Increasing
warmth and moisture ahead of a late week cold front will bring our
best chance of thunderstorms around Thursday Thursday night
before things begin to dry out under high pressure.

Details...

Tuesday through Wednesday night...

Tuesday will be cooler and wetter than memorial day as a low
pressure system approaches and crosses the region to the south.

Moisture spilling over the ridge brings increased cloudcover in the
morning before rain overspreads the area mid-late morning. Sne is
placed under the rrq of an upper level jet which will provide some
synoptic lift in addition to a southerly 30-40kt LLJ which develops
as the same time bringing speed convergence in the low levels.

This helps pull in a swath of higher pwats (>1") which all
together should bring from 0.25"-0.75" of rain by Wednesday
morning, with some locally higher amounts. Instability is
lacking and we're not expecting any thunder with this system.

Colder air filters in aloft (850mb temps ~5c) and this with the
southerly track of the low associated NE flow at the surface
will bring cool temps, in the upper 50s and low 60s.

The best lift forcing moves off early Wednesday and rain should taper
off, if briefly. Clouds thin but hang around. Beyond this point
there remains a good deal of uncertainty in the evolution of
the next low pressure system and where it tracks, but there is
general consensus that a warm front will begin to work its way
north through the region on Wednesday. This stems from a low
forming to our northwest. Along with warmer temperatures (upper
60s-70s) this brings another round of rain showers Wednesday
afternoon into the early morning hours of Thursday.

Thursday and Friday...

we may get a reprieve from the rain for a time, Thursday morning
into the early afternoon. Temperatures will be on the rise (
dewpoints as well) as all of southern new england gets into the warm
sector. This will help increase instability ahead of the cold
front and lead to thunderstorm chances in the
afternoon overnight hours. Shower and thunderstorm chances
increase the latter half of Thursday into Friday as the cold
front approaches from the west. Timing is uncertain, but for now
sticking with the more consistent guidance showing an earlier
passage, which would have showers exiting the region early
Friday. This as northwest winds bring a much drier column
overhead with pwats back down near 0.5". Cooler temps in the
post frontal air mass should bring highs in the 70s.

Saturday and Sunday...

best chance of a nice weekend day looks to be Saturday under surface
high pressure and slight ridging at the mid levels. The average high
for boston on the first day of meteorological summer is 71, right
around what is currently forecast for Saturday. So, at this point,
its looking like a seasonable start to summer, with widespread 70s. The
latter half of the weekend looks more unsettled ahead of an
approaching shortwave.
