Synopsis
A weak cold front sweeps across the area overnight. Behind the
front, a brief period of drier and less humid weather will be
with us for Tuesday. The front returns north on Wednesday as a
warm front. Humid and very warm conditions overspread the
region Wed afternoon through Thursday. The return of this
summer-like airmass will be accompanied by the risk for
scattered thunderstorms Wed and thu. A cold front sweeps across
the area late Thu setting the stage for dry and less humid
weather Friday into the weekend.

Near term until 6 am Tuesday morning
The last of the showers is moving past the outer CAPE and
nantucket. Per satellite, skies are clear or mostly clear across
most of southern new england. Most of the clouds, over CAPE cod
and the islands, will be moving off to the east by midnight.

Weak cold front has moved through the berkshires and is moving
east. This will move through southern new england overnight with
light south winds becoming light northwest. Dew points, which
were near 70 earlier, will trend to the mid 60s, possibly low
60s in northwest ma. Based on this, we continue to expect
overnight min temps in the 60s.

Short term 6 am Tuesday morning through Tuesday night
445 pm update ...

Tuesday ...

post frontal airmass settles over the region tomorrow with good
column drying as pwats fall below 1 inch, providing abundant
sunshine. This dry air mixes to the surface with dew pts in the
mid to upper 50s, although afternoon seabreezes will keep dew
pts in the low to mid 60s. Still much more comfortable than the
mid 70 dew pts of today.

Not as hot as today but warm with highs in the mid to upper 80s,
just more tolerable with dew pts in the mid to upper 50s.

Overall a real nice late summer day by new england standards.

Tuesday night ...

pleasant during the evening hours with dry weather and
comfortable humidity hanging on. Second half of the night warm
front approaches from the southwest with risk of showers and
thunderstorms toward daybreak. Also patchy fog possible late.

Long term Wednesday through Monday
*** will update after thunderstorms exit ***
highlights...

* shower and thunderstorm chances Wednesday-Thursday
* a cold front brings dry & cooler conditions Friday through the
weekend
details...

Tuesday night through Thursday... .

A series of shortwaves and a strong cold front will bring periodic
shower and thunderstorm chances through Thursday. Starting late
Tuesday early Wednesday a warm front will begin to make its way
north across the region. With this warm front comes a very humid
airmass (dewpoints rising from the 50s Tuesday to the low 70s early
Wednesday, and pwats back up near 2"). As mid level energy
associated with a weak shortwave moves through and interacts with
the warm front it initiates showers and thunderstorms. There is
potential for some strong thunderstorms given the moist warm sector
and CAPE values 2000-3000 j kg with moderate to good bulk shear (35-
45kts). Any storms that form could produce gusty winds and heavy
downpours given how much moisture is in the column. At the moment
the best chance for heavier rainfall looks to be areas north and
west, with less QPF over southeast ma coastal ri. However, we're
still too far out to nail down specifics with much confidence.

The surface low and upper trough over the great lakes region then
slides north and east late Wednesday to Thursday dragging its cold
front across southern new england overnight Thursday. Along and
ahead of the front we again see shower and thunderstorm chances with
>2000 j kg CAPE and good shear parameters (>40 kts bulk shear).

Temperatures remain relatively steady through this period in the
80s before a cool down arrives to end the week.

Friday through Sunday...

the cold front exits off the south coast or in the vicinity by
Friday morning leaving a cooler and much drier post frontal airmass
in its wake. Pwats drop to 0.5" while surface dewpoints in the low
50s will make the air feel refreshing compared to the previous week.

Surface high pressure and mid level ridging builds in through the
period bringing dry and pleasant weather through the weekend. Cold
pool aloft (850mb temps 7-10c) will allow for surface highs in the
70s each day.

Aviation 02z Tuesday through Saturday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday night ... Moderate confidence.

Last of the showers are moving off CAPE cod. Lingering 800 to
1200 foot ceilings with these showers, but all of this is moving
off to the east. Observed conditions are mostly clear off-cape
and trending clear on-cape. Light south winds will turn from the
west and northwest as a weak cold front moves through overnight.

Tuesday ...

vfr and dry weather. Afternoon seabreezes near the coast.

Tuesday night ...

vfr and dry to start but becoming MVFR with chance of showers
and thunderstorms toward morning.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
