.SYNOPSIS...
Showers and thunderstorms will come to an end tonight.
Oppressive heat and humidity continues Friday and Saturday. Dry
weather expected on Friday. Another round of severe storms and
flash flooding are possible on Saturday as a cold front slides
through. Behind the front cooler and more comfortable conditions
are expected Sunday into the middle of next week.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
7 PM Update:

Focus of severe storms continues to drift south across CT, RI,
and SE MA. Still seeing some stronger cores with 50-60kt showing
up in lower levels on KBOX and TBOS. These storms strengthened
as they ran into area of max instability as seen on
SBCAPE/MLCAPE mesoanalysis, and eventually will head offshore
and become elevated as it runs into more stable airmass.
Additional storms back across CT will continue to pose a threat
of damaging winds as well.

We're planning to drop the Severe Thunderstorm Watch for
western, central, and NE MA but continue it elsewhere until
expiration at 8 PM.

Also watching flash flood threat, especially where storms have
been training. Fortunately storm motion has been fast enough to
limit it so far.

Once we get past storms this evening, guidance suggests there
will be some clearing and areas that do receive heavy rain could
develop some localized fog. Despite the front moving through
tonight will remain warm and muggy with lows in the lower to
middle 70s.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
Friday...

A mid level ridge will build from the the central Great Lakes early
in the day into the eastern Great Lakes/western New England by late
on Fri. A weak high will nudge into southern New England.

Dangerous heat expected to continue across southern New England.
Still looks like the peak of the heat temp wise will be on Fri. Will
see W to WNW flow at 925 hPa with temps of 23-26 degrees C.
Anticipating strong mixing per NAM/GFS Bufkit soundings, so bumped
temps up toward the 90th percentile of guidance. Should see
widespread highs in the low/mid 90s. Though it may stay in the 80s
along the immediate coastline as the seabreeze develops. Did nudge
down our dew points a bit given the W/WNW flow and deep mixing. Did
not go quite as low as ARW/FV3 guidance, but it is not out of the
question especially if you mix down the dew points at the top of the
mixed layer. Due to this have dew points in the mid 60s to lower
70s. The result are heat indices between 90-100, so think the
current Heat Advisory still looking good.

Given the stronger wind fields that were in place on Thu/Thu night
think that south facing beaches still could see a moderate risk for
rips despite wave heights diminishing. A Rip Current Statement
has been issued for all southern facing beaches 8 AM to 8 PM
Friday, beachgoers will want to remain vigilant.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
Highlights

* Oppressive heat/humidity continues Sat.

* Strong to severe storms possible Sat. Heavy downpours could result
  in localized flash flooding.

* Cooler and less humid Sun and into next week.

Friday Night through Saturday...

Mid level ridge axis over the eastern Great Lakes/New England Fri
eve builds offshore by early Sat. The next shortwave/trough lifts in
from the Great Lakes region early in the day and eventually through
by the evening. This will slide a cold front through the region and
perhaps another MCs.

Main change to the forecast was to extend the Heat Advisory across
portions of the south coast, Merrimack and CT Valley through late
Sat. Not expecting much relief from the heat Fri night into Sat as
flow turns more to the WSW/SW at 925 hPa. This will surge upper 60
to mid 70 degree dew points into our region. Expecting overnight
lows to hover right around those dew points, so will be quite warm as
we head into Sat. The question on Sat will be how quickly the front
moves in and if a MCs impacts us. At this point have more confidence
in the heat/humidity during the first half of the day. Ahead of the
incoming front the WSW/SW flow will bring 20-25 degree C overhead at
925 hPa. The result will be highs in the mid 80s to low 90s. Should
see more widespread low 90 degree readings where the Heat Advisory
has been expanded, much of the CT River Valley/south coast and into
the Merrimack Valley. Dew points will be in the low/mid 70s, so heat
indices range from the mid 80s to upper 90s.

On top of the heat concern will have another day where there is a
risk of scattered strong to severe thunderstorms. Somewhat uncertain
to the exact location/track of an MCs pushing in from the west.
Quite difficult to pinpoint these things 3 days out. Our environment
looks quite favorable with deep layer shear in the 0-6 km layer of
30-50 kts as the cold front is sliding in. Instability at this point
looks like roughly a few hundred to perhaps 1000 J/kg of MLCAPE. Low
level lapse rates are 6-8 degrees C and mid level lapse rates are
the typical meh around 5-6. Another anomalous 1.5-2+ inch PWAT plume
advects in with warm cloud layer depths of 3-4.5 km. Given the
environment will have the risk for scattered strong/severe storms
and localized flash flooding. The severe risk highlighted quite well
by the latest CSU ML probs for Day 3 with a 15-30 percent chance of
a severe wind risk for our area and low probs for a hail threat.

Did dial back the default NBM precip chances as am just not sure
where the MCs coming in from the west will track. The GFS/ECWMF
guidance puts us more under the risk whereas the NAM/CMC
highlighting a bit further south. If the NAM is correct then we
could actually have parts of the region where we get no precip.
Given the uncertainty capped things at chances of precip. Hopefully
will have better agreement later today/Fri.

Sunday through Wednesday...

Should see relief from the heat as a more seasonable airmass moves
in behind the cold front. Flow looks like it will be cyclonic
through at least early in the week before a ridge builds into the
Great Lakes region by roughly mid week. Given the cyclonic flow
there does appear there will be a few shortwaves/troughs lifting
through. Tough to time these things this far out especially given
they likely are going to be convectively driven.

Does appear that we are drier and less humid, however given the
upper forcing am not sure we will be completely dry through this
period. Did bump up precip chances on Sun to show an isolated risk
for showers as a shortwave lifts in. Could see some isolated
showers/storms on Mon/Tue across the interior as more waves swing
in. Definitely not looking like there are any washouts at this point
in time. Temps range from the mid 70s to the mid 80s for highs each
day.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
Forecast Confidence Levels:

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

00z TAFs: Moderate confidence. Uncertainty is due to timing of
improvement tonight and if any low clouds/fog form overnight.

Showers/storms across CT, RI, and SE MA slowly weaken early
tonight and move offshore, leaving VFR ceilings across most of
region. Expecting to see patchy fog/low clouds in areas that
received heavy rain earlier which will result in areas of IFR.
Should be more widespread near Cape Cod/Islands with continued
S/SW flow.

Conditions improve rapidly to VFR Fri morning as winds shift to
W/NW, but coastal sea breezes develop by midday. VFR Fri night.

KBOS TAF...High confidence.

KBDL TAF...High confidence.

Outlook /Saturday through Tuesday/...

Saturday: Mainly VFR, with areas MVFR possible. Chance SHRA,
isolated TSRA.

Saturday Night: VFR. Chance SHRA, isolated TSRA.

Sunday through Tuesday: VFR.

&&

.MARINE...
Forecaster Confidence Levels:

Low - less than 30 percent.

subside, and expect winds to drop below SCA on all waters later
tonight. Lingering showers/storms come to an end early tonight
followed by areas of dense fog, especially on south coastal
waters. Quieter weather Fri with local sea breezes nearshore.

Outlook /Friday Night through Tuesday/...

Friday Night: Winds less than 25 kt. Areas of seas approaching
5 ft.
