Synopsis
Low pressure over southern quebec will move southeast overnight
to near downeast maine by Friday morning. Low pressure will head
out to seas south of nova scotia on Friday as high pressure
builds in from the west. High pressure will crest over the
region Saturday morning before shifting offshore in the
afternoon. A warm front will push in from the west Saturday
night and will shift east of the area Sunday morning. A cold
front will move in from the west Sunday afternoon and evening.

The front will shift offshore Sunday night followed by high
pressure on Monday. High pressure will shift in from the west
Monday night and will crest over the region early Tuesday. A
warm front will lift into the region from the southwest Tuesday
afternoon and will stall over the region Tuesday night and
Wednesday.

Near term until 6 am Friday morning
650 pm... Compact fast moving system will sweep across cwa
overnight, and current shra over CWA associated with waa, and
convection over ny being forced by cold front. Triple point of
system will likely cross far NRN zones this evening, and strong
850 mb jet should produce a decent burst of rain over NRN zones
as that convection to our west moves through, although in a
weakened state. Full sfc warm sector unlikely to mix down over
the strengthening marine lyr, but should temps staying steady
once he warm front thru, and tds might rise a bit. Will hold the
chc of thunder given the convection developing in ny, and the
strong mid-lvl jet, but it will all be elevated, so any chc of
strong wind mixing down is very small. Think the rain showers
will end around or shortly after midnight in the south, but
will continue through the overnight in the NRN and eastern
zones as the upper lvl deepens a little and the occlusion slides
s and E through central me.

Previously... S WV trof is swinging across the ERN great lakes.

Decaying convection from overnight is still hanging
tough... Though warming cloud tops and a lack of lightning points
towards continued trend towards an area of showers moving thru
late this afternoon and early evening. A second round of
convection is expected to develop along the trailing cold front
shortly. The question is intensity and coverage of this
convection in the wake of early day rain. If it remains
scattered... We are less likely to see an active area of thunder
move into the forecast area. Lapse rates are steep enough to
support scattered elevated storms into the evening otherwise.

The warm front is also forecast to get hung up across the middle
of the forecast area. To the N it will remain cool but continue
to moisten... Allowing low clouds and fog to form tonight. Some
model guidance suggests areas of dense fog are not out of the
question for midcoast me. To the S atmosphere remains more well
mixed and mild for this time of year.

Short term 6 am Friday morning through Friday night
As trof crosses the area and low pressure drops se... Winds will
flip nly and increase. Pop is higher across WRN me underneath
the upper low center... But these showers should quickly exit the
area over the first half of the day. With offshore flow and caa
mixing should be deep enough to reach h8. Temps mixed down from
that level yields widespread 60s and a run at 70 for SRN nh.

Winds... Especially near the coast... Will get gusty as well with
possible gusts up to 30 mph.

Fri night the next ridge of high pressure moves into the area.

Temps will cool off quickly around sunset with clearing skies
and winds diminishing. Should see widespread readings in the 40s
with some upper 30s in NRN valleys.

Long term Saturday through Thursday
Models in fairly good agreement through early next week
in the extended forecast with some warm weather on the
horizon...

high pressure will crest over the region early Saturday
morning before shifting offshore in the afternoon. After
a mostly sunny start to the day expect increasing clouds
in the after noon as a warm front approaches the region
from the southwest. Majority of the forecast area should
see a dry day but expect at least a few showers to push
into the connecticut valley during the early evening
hours. High temperatures will range from the mid to upper
60s north and lower to mid 70s south.

Warm front will push into the region from the west
Saturday night driving a band of rain through the region
overnight. QPF with this system continues on the light
side with most areas seeing between a quarter and three
quarters of an inch. Should be a quick hitter with showers
pushing east by daybreak. Lows overnight will range from
the mid 40s north to the mid 50s south.

Lingering low level moisture Sunday morning will quickly
be swept east as boundary layer winds turn into the
southwest behind the front. Expect temperatures to quickly
bounce into the upper 70s and lower 80s across a good
portion of southern and central new hampshire and maine.

Cold front approaching from the west will set the stage
for afternoon and evening showers and thunderstorms.

Shear values for Sunday still looking healthy so some
severe cells will be possible with wind damage the major
threat. Hail threat looking more marginal but could be a
factor in northern zones where freezing levels will be
lower.

Cold front will slow to a crawl as it pushes into the
region Sunday evening. This will prolong convection in
southern and eastern zones through the evening hours
before diminishing toward midnight as the front slides
offshore. Low temperatures will range from the mid 40s
north to the mid 50s south.

Lingering clouds will gradually diminish on Monday as
high pressure builds in from the west. Expect a mix of
sun and clouds in the morning to give way to mostly
sunny skies in the afternoon. High temperatures will
range from the mid 60s to lower 70s north and mid to
upper 70s in the south.

High pressure will continue to build in from the west
Monday night and will crest over the region by daybreak
Tuesday. After mostly clear evening looking for high
clouds ahead of an approaching warm front to filter into
the region from the west after midnight. Lows will range
through the 40s north and upper 40s to lower 50s in the
south.

Warm front will push into the region from the southwest
on Tuesday as high pressure shifts offshore. Expect the
morning to be dry across the region with showers moving
into the region from west in the afternoon. Highs will
range from the upper 50s to mid 60s north and mid 60s to
lower 70s south.

Warm front will gradually push into the region Tuesday
night and will stall over the region on Wednesday.

Aviation 00z Friday through Tuesday
Short term... Next trof moves thru tonight. Ahead of it a
decaying band of showers will move across much of the forecast
area late this afternoon. Another round of convection is
expected to develop over central ny this afternoon and continue
ewd into new england tonight. The surface warm front is forecast
to stall across WRN me overnight... With low clouds and fog
forming N of it. Pwm... Aug... And rkd are expected to see at
least a several hour period of ifr or lower conditions before
offshore winds mix out low levels Fri morning. While conditions
improve to MVFR Fri morning andVFR by the afternoon... Surface
wind gusts may reach 25kt along the coast early in the day.

Llws: N of the warm front surface winds will remain light and
onshore... While a ssw LLJ develops ahead of the approaching cold
front. A period of marginal llws is possible at rkd before the
llj moves E early Fri morning.

Thunder: a window for tsra is possible at all terminals late
this afternoon thru about midnight. While not likely isolated
tsra are possible and may hold together long enough to impact
terminals... Especially across nh. Right now confidence is too
low to include within tafs.

Long term...VFR Saturday. Areas of MVFR ifr ceilings Saturday
night with the passage of the warm front.VFR Sunday with areas
of MVFR ifr in afternoon showers and thunderstorms.VFR Sunday
night through Tuesday.

Marine
Short term... SCA remains in effect outside of the bays for
increasing SW flow and seas tonight. Wind will shift early fri
to a nly direction and increase gusts closer to 30kt. Winds and
seas gradually diminish Fri night.

Long term... Sca's may be needed Saturday night.

Gyx watches warnings advisories
Me... None.

Nh... None.
