.SYNOPSIS...
More in the way of sunshine on Sunday will allow for readings
to climb back into the lower 70s. High pressure will park
offshore early next week with southeast winds over land. This
will keep temperatures a bit cooler than what they could be and
also keep clouds in the picture. It will continue to warm up
with increasing humidity mid next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
A slow moving front continues to sag southward through the
evening, with clearing skies pressing southward as well. The
front stalls, and some low level moisture begins to increase on
a light east flow. Some fog can`t be ruled out along parts of
the MidCoast tonight, but overall it doesn`t look like the
airmass moistens up quite enough to bring more widespread
coverage tonight.

Across most of the interior, and especially the north, clearer
skies allow for more radiational cooling overnight. Through the
northern valleys, some patchy valley fog is likely by morning as
lows cool into the mid 40s, with some low 40s likely in more
sheltered spots. Further south into southern New Hampshire,
enough cloud cover likely remains to keeps temp into the low 50s
through the night.

&&

.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
Temperatures start to rebound tomorrow as high pressure builds
in from the east. This makes for sunnier conditions, and also a
light but steady onshore flow. Highs likely warm into the low
70s across much of the interior, with some mid 70s likely
through the Connecticut River Valley. The onshore flow keeps the
coast into the 60s for highs, with the immediate shoreline
likely confined to the low 60s. Most water bodies have warmed
into the 60s by now, but some northern water bodies and rivers
are likely still in the upper 50s.

Mostly sunny skies are expected along the coast, with gradually
increasing pop up cloud cover further inland. Isolated showers
and possibly a stray thunderstorm likely form by the afternoon
hours across the higher terrain, but remain limited in coverage
and brief.

Tomorrow night looks pretty quiet as high pressure persists
across New England. Mostly clear skies allow for another night
of radiational cool across the north with lows dipping into the
40s, and generally into the low 50s across the south.&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
No big changes to the going forecast as the 12z deterministic
and ensemble suite are in reasonable agreement and showing
decent run to run continuity. The main theme will be high
pressure hanging out just offshore early next week which will
mean southeasterly winds over the land with the potential for a
good amount of clouds. The onshore flow will keep temperatures
somewhat down as well. The high is modeled to move farther out to sea
mid week, allowing for more of a southwesterly flow regime to
take shape. This should allow for more summery weather with
temperatures well into the 80s by Thurs along with increasing
chances of afternoon thunderstorms.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Short Term... Mainly VFR prevails, but some MVFR to near MVFR
ceilings linger across southern terminals into the evening.
Another period of MVFR ceilings is possible with a marine
stratus deck late tonight. A period of valley fog is likely LEB
and HIE late tonight. VFR then prevails on Sunday and Sunday
night.


Long Term...VFR likely prevails through midweek next week, with
nighttime valley fog possible each night. Marine fog is
possible at RKD by midweek as the airmass moistens. Chances for
scattered afternoon showers and storms increase across interior
terminals starting Wednesday and continue through late week.
More widespread showers and storms are possible late Thursday or
Friday.

&&

.MARINE...
Short Term...Fair conditions persist through Sunday night as a
front stalls across the waters. High pressure gradually builds
across the waters through Sunday night.


Long Term...High pressure gradually moves eastward across the
North Atlantic through midweek next week with generally fair
conditions. However, fog will be possible. A cold front
approaches late in the week, with SCA conditions possible in
southwesterly flow ahead of the front by late Wednesday.
