.DISCUSSION...
KEY MESSAGE 1...Scattered showers and perhaps isolated t-storms this
afternoon. Focus across eastern New England where activity may
linger into part of the evening. Dry/cooler weather follows tonight
into Mon night.

A dynamic shortwave/cold pool aloft will drop south into the region
this afternoon. Although the low level moisture will be
lacking...the dynamics/cold pool aloft will result in several
hundred J/KG of Cape developing which potentially may approach 1000
J/Kg near the south coast. This will trigger scattered this
afternoon with potentially isolated t-storms. Perhaps some gusty
winds/small hail would be possible if a t-storm is able to develop
given cold pool aloft and modest T/Td spreads. Activity will focus
across eastern New England...where it may linger into part of this
evening.

Otherwise...drier/cooler air will continue to work into the region
tonight on northerly flow behind the cold front. Low temps tonight
will be in the 50s...But some of our typically prone low-lying
locations will briefly decouple and allow for lows in the middle to
upper 40s.

Large high pressure builds across the region Mon into Mon night.
This will result in sunny skies on Mon with highs in the upper 70s
to near 80...But cooler upper 60s to lower 70s on parts of the very
immediate coast with onshore flow. Mainly clear skies with
light/calm winds Mon night will result in a good night of
radiational cooling. Low temps Mon night will be in the 40s across
the outlying locations to generally lower to middle 50s elsewhere.
However...the Urban Heat Island of Boston will only drop to around
60 as southwest flow begins to warm advect.

KEY MESSAGE 2...Summerlike temperatures expected Tuesday through the
weekend, with a multi-day stretch of 90+ degree temperatures in some
locations possible.

We are still anticipating a steady warming trend to our temperatures
starting Tuesday, as an amplified upper level ridge moves in and
then begins to flatten around late week into the weekend. By
Wednesday, 850 mb temps are in the mid to upper teens C range to go
along with an uptick in humidity levels. We could be looking at a
few consecutive days of 90+ degree temperatures with heat indices
possibly warranting heat headlines. The bigger uncertainty on the
temperature forecast is the potential for thunderstorms, which is
still a little uncertain, but the chances for storms increases as we
move into late in the week into the weekend as the ridge axis
flattens and allows for increasing midlevel winds to interact with
the northern/western periphery of the building heat.

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
Forecaster Confidence Levels...

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

00z TAF Update...High confidence.

Band of SHRA moving southward from northeast MA to bring brief
MVFR ceilings/visbys from 00-05z from north to south, mainly
affecting ORH/BED/BOS south and east. This will also be
accompanied by NE winds 10-15 kt with gusts 20-25 kt.
Ceilings/visbys should improve to VFR shortly after rain ends,
although NE winds remain around 10-13 kt overnight. VFR then
prevails through Monday night.

As for winds...NW wind gusts of 20-25 knots this afternoon shift to
the N tonight. Brief N wind gusts of 20-25 knots with the strongest
near the coast before they gradually diminish or even decouple in
the typically prone spots overnight. Light NE winds Mon becoming SW
Mon night.

KBOS Terminal...High confidence in TAF. Brief MVFR thru 02z in
SHRA/stratus but conditions improve to VFR. NE winds around
12-16 kt with gusts 25 kt thru 03z. Gusts then ease but remain
around 10-15 kt thru midday Monday, then potential seabreeze
around 17z as gradient slackens.

KBDL Terminal...High confidence in TAF.

Outlook /Tuesday through Friday/...

Tuesday through Tuesday Night: VFR. Breezy.

Wednesday: VFR. Breezy. Slight chance SHRA.

Wednesday Night: Mainly VFR, with local IFR possible. Breezy.
Chance SHRA, slight chance TSRA.

Thursday: Mainly VFR, with local MVFR possible. Breezy. Chance
SHRA, slight chance TSRA.

.MARINE...
Forecaster Confidence Levels...

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

Tonight through Monday night...High confidence.

Shortwave/cold front crosses the region by early-mid evening. This
will bring a surge of N wind gusts of 25 knots especially across our
eastern waters. Small craft headlines have been posted for most of
our waters. High pressure building into the region Mon will result
in winds/seas dropping below small craft headlines from north to
south...but it may take until late afternoon/early evening across
our southeast most outer-waters.

Lastly...will need to watch for a few showers and isolated t-storm
developing nearshore later today into early this evening...
particularly near the south coast. Gusty winds/small hail and
lightning possible with any t-storm.

Outlook /Tuesday through Friday/...

Tuesday: Winds less than 25 kt.

Tuesday Night: Winds less than 25 kt. Seas locally approaching
5 ft.

Wednesday: Low risk for Small Craft Advisory winds with gusts
up to 25 kt. Areas of seas approaching 5 ft.

Wednesday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Seas up to 5 ft. Rain showers likely, slight
chance of thunderstorms.

Thursday: Winds less than 25 kt. Seas up to 5 ft. Slight chance
of rain showers.

Thursday Night: Winds less than 25 kt. Areas of seas
approaching 5 ft. Slight chance of rain showers.

Friday: Winds less than 25 kt.
