.SYNOPSIS...
A couple of weak disturbances will bring scattered showers at
times late tonight into Wednesday with a few thunderstorms
possible Wednesday. Cooler than normal temperatures Tuesday
will be followed by a warming trend with hot and humid
conditions Thursday. The heat and humidity will be accompanied
by a chance of thunderstorms, some severe possible, late
Thursday and Thursday evening ahead of a cold front. Then more
seasonable and drier conditions follow for Friday and Saturday.
Looking ahead to early next week, it appears significant heat
may impact southern New England.

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Key Messages:

* Stratus and patchy fog redeveloping

* Scattered showers possible late

Weak mid level ridging will set up over New Eng tonight with weak
large scale subsidence for most of the night. However, deepening
moisture plume approaches from the west ahead of a weak shortwave so
scattered showers may develop late tonight from west to east.
Otherwise, ridging at the surface will extend west across SNE with
continued low level SE flow providing abundant low level moisture.
Result will be stratus and patchy fog redeveloping and expanding
across the region tonight. Lows will range from 55 to 60.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
Key Messages:

* Lots of clouds with scattered showers at times Tue and Tue
  night

* Below normal temps Tue but increasing humidity

Tuesday and Tuesday night...

Unsettled pattern developing as a couple weak shortwaves will be
moving through. Meanwhile, an area of deep moisture sets up across
SNE with anomalous PWAT plume increasing to 1.75 to 2 inches.
Forcing for ascent is weak but enough forcing acting on high
moisture will lead to scattered showers moving through. Timing of
these showers is uncertain and not expecting a washout, but there
will be showers at times Tue into Tue night. Not expecting any
thunder but may see some convective showers developing as stability
decreases.

Otherwise, expect gloomy conditions with lots of stratus through the
period. The cloud cover and SE flow will result in cooler than
normal temps Tue with highs upper 60s to lower 70s. Dewpoints will
be climbing into the low and mid 60s so there will be somewhat of a
humid feel to the airmass. A milder night Tue night with lows in the
lower 60s.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Key Messages:

* Becoming hotter each day through Thursday, then cooling off a bit
  Friday through the weekend before our hottest stretch of the year
  early next week.

* Severe weather possible on Thursday, greatest risk is damaging
  winds

* Dry Friday and Saturday but chance for some showers at some point
  in the weekend.

Wednesday and Thursday...

The return of more summer-like warmth comes Wednesday as southern
New England will be sandwiched between high pressure  over the
Atlantic and low pressure moving through the Great Lakes. This
places us beneath warm, moist SW flow until a cold front sweeps
through late Thursday. Before this, 925 temps reach 20C on Wednesday
and near 25C on Thursday which should lead to high temperatures in
the 80s and upper 80s/low 90s respectively. It will also feel very
humid as dewpoints surge into the upper 60s Wednesday and even low
70s potentially by Thursday. Not only will this increase the
apparent temperatures, it will contribute to a great amount of
instability on Thursday; guidance indicates several thousand J/kg of
MUCAPE available. This, combined with mid level lapse rates
approaching 7 c/km and 30-40 kts of 0-6 km bulk shear will lead to a
decent chance of severe weather on Thursday. SREF guidance indicates
a 40-50% probability of CAPE > 1000 J/kg and bulk shear >30kts,
maximized over western and central SNE. Timing and severity will
depend on several factors, including how quickly that cold front
moves through. At this point the ECMWF would indicate a quicker
passage, closer to the peak heating of the day while the GFS is
slower, after sunset. Stay tuned.

Friday through early next week...

Friday into the weekend we`ll be under drier W/NW flow and with a
lingering trough/cyclonic flow aloft leading to some diurnal clouds
Friday and potential for a weak shortwave moving through around late
Saturday/early Sunday which may bring some showers but confidence is
low at this point. What is more certain is that the pattern will be
changing as we go into next week with high confidence of a building
ridge and very hot temperatures for the first half of next week. At
this point both the EPS and GEFS indicate a 70+% chance of 90+F on
Monday and a near certainty by Tuesday.
