Area forecast discussion 
National Weather Service Taunton Massachusetts
1011 PM EDT Tuesday Jun 2 2015

Synopsis...
cold front moves farther offshore overnight. A light north flow
will bring cool drier air to the region. High pressure along with
sunshine and milder temperatures return for Wednesday and Thursday.
Showers are possible Thursday night into Friday. Then high
pressure and dry weather return for the weekend. Weather pattern
may become unsettled early next week. Temperatures warm through the
period...finally reaching seasonal norms by early next week.

Near term /until 6 am Wednesday morning/...

Cloudy skies all areas. But breaks in the lower deck show over
north central mass. The back edge of these clouds is over
northern and western New York with mostly clear skies over
Ontario. Trend of the clearing would bring it to northwest mass
around 6 am with mainly cloudy skies over the remainder of
southern New England. We adjusted sky cover forecasts to reflect
this trend.

Observed temperatures are in the middle 40s to low 50s...observed dewpoints
are in the 40s. Expect min temperatures in the 40s.

Short term /6 am Wednesday morning through Wednesday night/...
Wednesday...

Weak short wave ridging builds into the area along with surface
settling over the area. Cross sections reveal some low level
moisture may remain trapped beneath subsidence inversion so scattered to
perhaps broken scu/cumulus may develop during the afternoon. Nevertheless
partial June sunshine will combine with light winds for very
pleasant weather. Afternoon seabreezes will cool off the coastline.
Strong June sunshine will warm maritime airmass with highs in the
mu60s for most locales...70-75 CT River Valley and 55-60 along the
immediate coast given light onshore winds.

Wednesday night...

1026 mb high over the area will combine with light winds and
relatively dry airmass for temperatures to fall fairly quickly with sunset
especially inland removed from the maritime layer. Dry weather
prevails with middle and high clouds arriving toward morning on the
south-southwest horizon.

&&

Long term /Thursday through Tuesday/...
highlights...

* mainly dry with below normal temperatures Thursday
* a few showers possible Thursday night into Friday and again Friday night into
Sat as a cold front approaches
* dry and seasonable sun then threat of showers returns Monday and Tuesday

Operational models are not in great agreement with this model run.
They are offset timing wise at the very least with the GFS being
slower than the European model (ecmwf). Seems the European model (ecmwf) ensemble mean has been more
consistent...if not the operational run as well over the last few
days so will guide the forecast towards that. Overall...we/ll start
the forecast off with zonal flow and high pressure Thursday.
Following that will be a cold frontal passage Friday night with a
few showers. Saturday and Sunday will see mostly dry weather as
high pressure builds in and then moves offshore. And finally some
more seasonable temperatures early next week ahead of another cold
front.

Thursday into Friday...high pressure moves offshore Thursday
allowing for a few showers to develop Thursday night into Friday
with a weak shortwave. Temperatures will be warming slowly but will
still be below normal.

Friday night into Saturday...a better chance for showers ahead of a
cold front that will move through the area early Saturday morning.
Again...not a washout but another chance for much needed rain.
Temperatures warm to near normal levels Saturday.

Sunday through Tuesday...temperatures continue to warm reaching
seasonal levels and possibly a few degrees above normal by Tuesday.
Sunday and Monday should be mostly dry with showers and possibly
thunderstorms on Tuesday with a cold frontal passage.
