Synopsis
Very warm and humid conditions will continue through mid week,
along with showers or thunderstorms at times. A cold front will
cross the region later this week, followed by cooler and drier
conditions.

Near term until 6 pm this evening
Only minor tweaks to the forecast this morning. Already had a
few brief spot showers pop up over portions of northern ct and
southern ma. Increased pops slightly this morning, as latest
mesoanalysis showed some lingering instability near our region.

Shear remains rather weak, on the order of around 20 kt, so not
expecting any thunderstorms just yet. Both mid and low level
lapse rates were poor, but should increase rapidly with the
increased sunshine and high humidity.

Main concern today will be the risk for excessive heat. After
looking at observed conditions from Sunday, though it necessary
to expand a heat advisory into portions of eastern ma using the
lower 2-day threshold of 95 degrees.

Expecting another shortwave to trigger another round of showers
and thunderstorms. Questions remain with the timing. Should
thunderstorms not arrive before sunset, thinking we will see a
diminishing trend as these storms move east into southern new
england. While shear values should be slightly higher than what
we saw on Sunday, thinking it will not be enough to sustain
storms much past sunset. This potential will need to be
monitored through the day.

Short term 6 pm this evening through 6 pm Tuesday
Showers and thunderstorms diminish rather quickly after sunset,
leaving most of the night dry. Increasing risk for more showers
and thunderstorms late Tuesday afternoon as a warm front passes
by.

Temperatures remain above normal, but dew points should not be
quite as high as today. This should prevent the need for a heat
advisory continuing into Tuesday.

Long term Tuesday night through Sunday
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.

waters and around nantucket this morning with visibility less
than 1 nmi. Smaller risk of poor visibility in patchy fog
tonight around nantucket.

Outlook Tuesday night through Friday ... Moderate confidence.

Tuesday night: winds less than 25 kt. Seas locally approaching
5 ft. Chance of rain showers and thunderstorms.
