.SYNOPSIS...
High pressure will move southeast of the New England coast today
with warm and dry conditions as a result. A shower is possible
as a weak frontal boundary crosses the region late tonight.
Temperatures and humidity begin to build on Independence Day
with this trend continuing through the end of the week. The next
chance for more widespread showers and thunderstorms is
expected this weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Another very quiet day expected today as a ridge of high
pressure anchored over the Northeast gradually eases off the New
England coastline this afternoon. This will allow for mainly
sunny skies with some high, thin Cirrus crossing the region from
time to time.

Temperatures will be slightly above normal for this time of the
year once again with mainly 80s across the region. It will
become cooler along the immediate coastline as winds become
onshore during the afternoon.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Clouds will continue to increase tonight as weak frontal
systems approach from the west. A few scattered showers will
make it into northern areas during the night. However, model
soundings suggest the atmosphere will remain initially dry in
the mid levels of the atmosphere. Any scattered precipitation
will be light.

There will be some patchy fog as well, however it will be
limited due to the cloud cover. Overnight lows will range from
the upper 50s to mid 60s.

A cold front will begin to dissipate over the region on
Independence Day. Isolated showers and perhaps a rumble of
thunder can be expected during the day. Temperatures will be on
the warm side once again inland with highs in the 80s. Cooler
conditions can be expected along the coastline where a sea
breeze develops during the day.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Highlights:

* Scattered showers are possible early with humidity expected to be
  on the increase for Independence Day

* Warm, humid airmass taking control over the weekend with
  showers expected mainly Saturday Afternoon into Sunday

Friday:

Friday looks to remain dry with partly cloudy conditions
throughout the region and temperatures topping out in the
middle to upper 80s. Dewpoints are expected to remain elevated
both days leading to a more humid feel to air. Low temperatures
are expected to range through the 60s from north to south.

Saturday and Sunday:

The pattern becomes more unsettled heading into the weekend as a
series of fronts approaches the region from the southwest.
There is quite a bit of model uncertainty on the surface features
but Saturday looks to start out dry with showers and thunderstorms
arriving by the afternoon. Severe weather threat looks minimal but
the greatest chance for thunderstorms looks to be over Southern NH
where the warm front has a greater chance of lifting. Farther north,
the threat for storms is lower as the front is likely to occlude.
Showers are expected to linger into Sunday with shower chances
decreasing later in the day. The airmass will remain very humid
through this period with high temperatures Saturday in the low to
mid 80s and mid to upper 80s on Sunday. A few spots in Southern NH
may hit 90 degrees by Sunday afternoon. Low temps remain warm in the
mid to upper 60s with low 70s possible the urban areas of Southern
NH.

Monday and Tuesday:

Generally pleasant weather is expected Monday. Beyond that, low
pressure passing to our north is likely to drop more showers and
thunderstorms into our region for Tuesday, however timing is
uncertain and confidence is low with this feature. High temperatures
are expected to remain in the 80s during this time.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
Short Term...VFR conditions today with seabreeze continuing to
kick in at the coast this afternoon and evening. A few patches
of valley fog possible tonight. A few widely scattered showers
late tonight into Thursday could bring a period of lowering
conditions.

Long Term...

conditions with localized IFR Saturday afternoon and evening in
scattered showers. MVFR to VFR conditions return on Sunday.

evening but sub-sca conditions are expected for the most part
tonight through Thursday.

otherwise an extended period of relatively light winds and low waves
are expected Friday through the weekend and into early next week.
