Synopsis
High pressure will shift offshore tonight as a warm front
approaches from the southwest. The warm front will lift into the
region on Thursday as low pressure shifts into southern quebec.

Low pressure will drop southeast through the region Thursday
night and will continue offshore on Friday. High pressure will
build in from the west Friday night and will crest over the
region early Saturday before shifting offshore. A warm front
will push east through the region Saturday night and will be
followed by a cold front late on Sunday. High pressure will
build in from the west Sunday night and Monday. Another warm
front will lift into the region on Tuesday.

Near term until 6 am Thursday morning
1020 pm... Temps somewhat variable tonight, as we are seeing
some areas that have decoupled and some that still have enough
boundary layer to prevent it. Temps were adjusted based on
current obs, but overall mins are similar to previous forecast.

Thinking that areas that decouple late will have to deal with
incoming cirrus and mid lvl clouds which will work against each
other.

625 pm... A few minor changes to forecast based on current conds,
just to line up t TD wind a little better. Tds running blo
guidance so, brought them up only very slowly overnight. Lows
range from upper 30s to around 40 in the mtns to mid-upper 40s
in the south.

Previously... High pressure builds over the area tonight. Winds
will continue to die down... Especially around sunset. Low temps
are expected to be cool but high cloud cover increasing and
lowering thru the night will mitigate any potential issues with
frost freeze temps.

Short term 6 am Thursday morning through Thursday night
Much of the day Thu is expected to be dry. Will have to watch in
the morning as the leading edge of the steep lapse rates move
into the area. Some very elevated showers may be possible as
this moves into the area. Otherwise the cloud cover will limit
warming and help keep the warm front to our sw... But temps
should still be seasonable.

Thunderstorms are expected to develop ahead of the next trof
approaching the area. All the significant instability is
forecast to remain well SW of the forecast area... So we have a
very low risk of any severe wx. If high enough temp dewpoint
combo can move into swrn nh a strong storm or two is possible
but not likely at this time. The most likely scenario is that
storms become increasingly elevated above the boundary layer.

While forecast soundings show enough MUCAPE to sustain thunder
thru much of the forecast area... These will pose little risk for
severe wx. Heavy rain would be the greatest threat with any
overnight thunderstorms.

Triple point and low pressure is expected to move thru the
forecast area late Thu night and into the gulf of me by fri.

That will keep the WRN part of the forecast area mainly dry
overnight... With ERN zones seeing the bulk of the rain. Upslope
showers follow the passage of the low pressure system.

Long term Friday through Wednesday
Models in fairly good agreement on synoptic pattern for the
end of the week and the weekend...

low pressure over the gulf of maine will continue to drift
off to the southeast on Friday as high pressure builds in
from the west. Moist flow off the maritimes will keep skies
mostly cloudy for much of the day before some sunny breaks
develop toward evening. High temperatures will range from
the mid 50s to lower 60s north and mid to upper 60s south.

High pressure will continue to move in from the west Friday
night and will crest over the region early Saturday. Expect
clearing skies overnight with lows ranging through the 40s.

High pressure will shift offshore on Saturday as a warm front
approaches from the west. After a mostly sunny morning...

clouds will be on the increase during the afternoon and expect
showers to move into far western zones during the early
evening hours. Highs will range from the lower 60s north to
the lower 70s south.

Warm front will push east through the region Saturday night.

Band of showers ahead of this boundary will gradually push
east through the region overnight and should clear the area
by Sunday morning. QPF not overly impressive with most areas
see a half inch or less. Lows overnight will range from the
mid 40s north to the mid 50s south.

A slow moving cold front will approach the region from the
northwest on Sunday. Looking for a mix of Sun and clouds in
the morning. Should see enough Sun to produce moderate
instability in the afternoon. Will have a fair amount of
uni-directional shear in place over the region but moisture
may be a limiting factor in holding down development. In any
case... Will likely see scattered afternoon and evening showers
and thunderstorms with the potential for wind damage with any
stronger cells. Highs will range from the mid 60s and lower
70s north and mid to upper 70s south.

Cold front will gradually slide offshore Sunday night
bringing an end to any lingering shower activity in southern
zones. Should see mostly clear skies overnight with lows from
the mid 40s north to the mid 50s south.

Narrow ridge of high pressure will build in from the west on
Monday. Looking for a fair amount of sunshine through the day
with highs in the lower to mid 60s north and upper 60s to mid
70s south.

High pressure will slide east Monday night as a warm front
approaches from the southwest. Expect variable cloudiness
overnight with the chance of a shower. Lows will range
through the 40s.

Warm front will lift northeast through the region on Tuesday
with scattered showers developing into a steadier rain as the
day GOES on in northern and eastern zones. Highs will range
from the upper 50s to mid 60s north and mid 60s to lower 70s
south.

Aviation 03z Thursday through Monday
Short term...VFR conditions expected thru Thu afternoon. Clouds
continue to lower and thicken thu... With front pushing into the
area in the evening. Widespread MVFR is expected with local ifr
in heavier shra or tsra into the night. Shra tsra clear from w
to E early fri... But MVFR CIGS likely linger into the morning.

Long term...

widespread MVFR ifr ceilings Friday... Improving toVFR Friday
evening.VFR Friday night and Saturday. MVFR ifr ceilings
developing Saturday night with areas of lifr.VFR Sunday and
Monday.

Marine
Short term... Winds and seas are expected to remain below sca
thresholds thru much of thu. Increasing SW flow will try and
bring seas to near 5 ft outside of the bays Thu night
long term... Sca's likely on Friday and again on Saturday night.
