Synopsis
High pressure will bring dry and seasonable temperatures today.

A cold front moves south across the region late tonight
followed by a surge of gusty northeast winds and unseasonably
cool temperatures Monday. A warm front approaches with
scattered showers across western areas Monday night. The
showers will fall heavily at times during Tuesday. Warmer and
more humid conditions return Tuesday night into Wednesday
night, along with scattered showers and a few thunderstorms as
a cold front approaches. Dry, seasonable conditions return late
this week, though a few showers are possible Thursday night into
Friday as a fast moving frontal system passes.

Near term until 6 pm this evening
8 am update...

current forecast looks on track. Some patchy fog in the river
valleys of far interior ma will lift and dissipate over the next
couple of hours. Otherwise, continue to expect high cloud shield
to gradually push south today.

Early morning discussion follows...

high pres remains in control today keeping deeper moisture and
shower risk south of new eng. High cloud shield expected to
gradually push south across the region today with the most
sunshine across northern ma but south coastal areas will see
partial sunshine. Highs should top out near 70 degrees for most
areas, a bit cooler along the coast where sea breezes will
develop.

Short term 6 pm this evening through 6 pm Monday
Mostly clear skies and light winds for much of tonight will
result in another chilly night with lows dropping into the 40s
for most locations. Main feature is backdoor cold front which
drops south across the region late tonight, mostly after
midnight, as strong high pres builds across quebec through mon.

A decent surge of gusty NE winds expected behind the front late
tonight into Mon morning, especially across eastern ma where a
period of gusts to 20-30 mph likely. Cross sections and
soundings show a shallow layer of moisture around 900-950 mb
developing by daybreak Mon across eastern ma then spreading west
within moist low level E NE flow. This will likely bring a fair
amount of lower clouds to the region on Monday, but expect some
breaks of Sun as well. It will be much cooler Mon as 925 mb
temps fall to 6-8c with a pocket of 4c air across NE ma. Highs
will range from the mid upper 50s across central and NE ma to
lower 60s lower ct valley and ri SE ma. A definite fall feel on
Monday.

Long term Monday night through Saturday
Highlights...

* rain and showers return Monday night Tuesday, with locally
heavy rainfall
* warm and humid Tuesday night into Wednesday night with
scattered showers and a few thunderstorms possible
* seasonable temperatures late this week, with a few showers
possible Thursday night into Friday
details...

Monday night...

high pressure across northern new england will shift E into the
maritimes during Monday night. Should see dry conditions
through around midnight, then area of rain will push into
central and western areas during the early morning hours on
Tuesday. Expect some gusty e-ne winds mainly along the coast.

It will remain chilly especially across the higher inland
terrain as temps bottom out in the lower-mid 40s.

Tuesday through Wednesday night...

warm front approaches Tuesday bringing periods of rain. Pwats
increase to around 2 sd above normal, so there will be a swath
of rain falling heavily at times on Tuesday. Could see between
0.75 and 1 inch of rainfall across central and western areas.

There may be some pockets of poor drainage and urban flooding in
the typically prone areas. At this point, still not expecting
any flash flooding as rainfall rates not high enough. Temps will
hold in the 60s across the region on Tuesday, possibly touching
70 along the S coast.

As the warm front moves through Tue night, temps will remain
steady or slowly rise as showers continue. Instability increases
with the milder, more humid air. K indices in the lower 30s and
surface based lis drop to -1 to -2. So have also mentioned
isolated thunder ahead of an approaching cold front later wed,
pushing through Wed night. Temps will rise to the 70s ahead of
the front during wed, which will help enhance any convection.

Thursday through Saturday...

medium range model guidance continues to signal a fast moving
northern stream mid level steering flow. At this point, any
leftover showers early Thursday should move offshore as high
pressure moves across. There may be a few showers as a weak h5
short wave moves across mainly after midnight Thursday night
into Friday, then more dry, seasonal conditions as another high
approaches Saturday.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
