SYNOPSIS
High pressure brings dry and warmer weather today. Summertime warmth
arrives Wednesday with heat peaking on Thursday with highs possibly
into the lower 90s. The main concern for scattered showers and
thunderstorms will be Friday and/or Saturday. Temperatures return to
seasonable levels this weekend.

.NEAR TERM /THROUGH TONIGHT/...
Key Messages...

* Sunny and warm this afternoon but with low humidity
* Highs today...upper 70s/lower 80s but a bit cooler on the coast

Details...

Upper trough shifts east of the region early this morning allowing
mid-level ridging to build in from the west. Rising height fields
coupled with plenty of sunshine and a dry airmass in place will
allow for a quick recovery in temperatures. After a relatively cool
start...we expect high temps to recover into the upper 70s and lower
80s across most of the region with relatively light winds. It will
be a few degrees cooler on the immediate coast as a weak gradient
allows for sea breeze development. Overall...a beautiful warm
afternoon but with low/comfortable humidity levels.

.SHORT TERM /WEDNESDAY/...
Key Messages...

* Dry/Pleasant tonight lows mainly upper 40s & 50s
* Sunny & Warmer Wed with highs in the middle-upper 80s
* Some Smoke/Haze moves in aloft from the west tonight and Wed

Details...

Tonight and Wednesday...

A mid level ridge axis will continue to build into southern New
England tonight and Wed. Low temps tonight will drop back into the
upper 40s and 50s in most locations with another good night of
radiational cooling. Rising height fields will allow for even warmer
temps on Wed with highs reaching the middle to upper 80s in many
locations away from cooling marine influence near the south coast.
Southwest flow around high pressure to our south will allow for
increasing humidity as dewpoints climb into the 50s. So definitely a
summer feel to the weather on Wed.

Lastly...a lot of the guidance indicates that smoke/haze from
Canadian forest fires will overspread our skies from the west
tonight and Wed. The bulk of this appears to be aloft...so main
impacts will probably be a hazy look to the sky at times.

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

* Heat and humidity continue through the late week with high
  temperatures in the mid to upper 80s and possibly low 90s Thursday
  & Friday

* Becoming more unsettled late Thursday with multiple opportunities
  for showers and thunderstorms through Saturday

* Trending cooler/drier by Sunday and Monday

Thursday and Friday

High heat and humidity peaks on Thursday as dewpoints surge under
continued southwest flow. Many locations in southern New England are
expected to experience dewpoints into the mid 60s on Thursday
afternoon. 925 hPa temps continue to rise as well, likely between
22C-25C, which supports surface temperatures in the upper 80s to low
90s on Thursday afternoon. Skies will start to cloud up Thursday
afternoon as well, as a weak pulse of short-wave energy traverses
over The Northeast. Modest height falls and moderate instability,
around 1000 J/kg or so of MLCAPE, will likely result in a few
afternoon thunderstorms/downpours. Not expecting any strong to
severe storms at this time as both lapse rates and deep layer shear
are not forecast to be favorable for organized storm development.

While Friday will remain hot and humid, increasing cloud cover will
mitigate those high temps somewhat... keeping highs in the mid to
upper 80s, but unlikely to reach 90. The heat finally breaks late
Friday as a cold front pushes through the region with another round
of showers and possibly a rumble of thunder. Latest model guidance
does not support impressive instability, but a couple of hundred
J/Kg of CAPE would be enough to support a few storms. We`ll have
more details as we enter the window of high resolution guidance
later this week.

Saturday through Monday

A low-pressure system moves through The Northeast on Saturday,
resulting in yet another wet Saturday for most of southern New
England. There is some uncertainty with respect to timing of
precipitation. A few solutions support a dry first half of Saturday
with a wet Saturday evening/Saturday night. Still time to iron out
those details, but right now ensemble means are suggesting 0.5 to
0.75" of rain between Saturday morning and Sunday morning.

By Sunday, model guidance suggests low-pressure will be exiting the
region. This would be followed by a cooler/dryer end to the weekend
with a similar pattern carrying into Monday.

.AVIATION /11Z TUESDAY THROUGH SATURDAY/...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

12z TAF Update...

Today through Wednesday...High Confidence.

VFR conditions continue through Wednesday. Winds become W at 5-10
knots this afternoon except for sea breezes developing on portions
of the immediate coast. Winds becoming light from the SSW direction
tonight and then increase to between 5 and 15 knots on Wednesday.

BOS TAF...High confidence in TAF. Sea breeze develops by 14z/15z.

BDL TAF...High confidence in TAF.

Outlook /Wednesday Night through Saturday/...

Wednesday Night: VFR.

Thursday through Thursday Night: VFR. Slight chance SHRA,
isolated TSRA.

Friday: VFR. Chance SHRA, isolated TSRA.

Friday Night: Mainly VFR, with local MVFR possible. Chance
SHRA, isolated TSRA.

Saturday: Mainly MVFR, with local IFR possible. SHRA likely,
isolated TSRA.

.MARINE...
Forecaster Confidence Levels:

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

Today through Wednesday...High confidence.

A ridge of high pressure building to our south will take control of
our weather today through Wednesday. The result will be winds/seas
remaining below small craft advisory thresholds.

Outlook /Wednesday Night through Saturday/...

Wednesday Night through Thursday: Winds less than 25 kt.

Thursday Night: Winds less than 25 kt. Slight chance of rain
showers, isolated thunderstorms.

Friday: Winds less than 25 kt. Slight chance of rain showers.

Friday Night: Winds less than 25 kt. Chance of rain showers.

Saturday: Winds less than 25 kt. Areas of seas approaching
5 ft. Chance of rain showers, isolated thunderstorms.
