.SYNOPSIS...
High pressure will build across the region today, then slowly
move southeast tonight into Sunday. A weak weather disturbance
will cross the area Sunday night followed by high pressure early
Monday. A cold front will approach Monday night and move
through on Tuesday. Another cold front will cross the area
Wednesday.
&&
.NEAR TERM /THROUGH SUNDAY/...
Update...
Have updated to include an Air Quality Alert in effect through
11 PM late this evening for the Interior and Coastal Downeast
regions.
Previous Discussion...
A Beach Hazards Statement remains in effect for the Downeast
coast from 8 AM this morning to 8 PM this evening. High pressure
will cross the region today, begin to move southeast tonight,
then exit southeast of Nova Scotia Sunday. A weak cold
front/pre-frontal trof should begin to approach northern Maine
later Sunday afternoon. Generally expect mostly clear skies
today through tonight. Smoke/haze will generally remain west of
the region today, However, smoke/haze could begin to return to
mostly western portions of the forecast area later today into
tonight. Due to uncertainty regarding the extent of the
smoke/haze, have not included this in the forecast yet though
this will have to be monitored. Could also have the slight
chance of a shower/thunderstorm across northern areas later
Sunday afternoon in advance of the approaching weak cold
front/pre-frontal trof. High temperatures today will range from
the mid to upper 70s north, to around 80 to the lower 80s
Downeast. Low temperatures tonight will range from the mid 50s
north to the mid to upper 50s Downeast. High temperatures Sunday
will range from the mid to upper 80s north, to around 80 the
lower 80s interior Downeast. Mid to upper 70s are expected along
the Downeast coast with onshore winds.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
We will remain in nearly zonal flow into mid-week before a trough
begins to amplify over Eastern Canada late in the week.
A broad upper level ridge of high pressure will be to our southwest
Sunday night as a weak shortwave trough slides to our east. A weak
upper level disturbance and shortwave crossing the area may bring an
isolated shower to the north Sunday night. Otherwise, the area will
begin partly cloudy then mostly clear late at night. High pressure
and upper ridging will build over the region on Monday bringing a
sunny and very warm day with inland highs well into the mid 80s.
Another weak upper level disturbance will cross the area Monday
night, possibly with a few showers over northern and western areas.
The shortwave weakens and loses moisture as it slides east and
southeast late at night diminishing chances for showers further
southeast. A weak frontal boundary will linger over the area Tuesday
as another shortwave begins to approach from the west. A large upper
trough will begin to dig to our west on Tuesday. Upper level flow
out from this trough, and around an upper level ridge well to our
south, will result in some diffluent flow which, combined with the
weak lingering frontal boundary, will likely produce some showers
and possibly thunderstorms over the north.
&&
.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
Weak upper level difluence will continue over the area Tuesday night
into Wednesday as a very weak surface frontal boundary remains
across the area. This will bring continued small chances for showers
through Wednesday. Otherwise, Tuesday night and Wednesday will
remain partly cloudy. The air will cool just a bit on Wednesday
following the weak front.
As we go into late week, a large upper trough will continue to take
shape and amplify a bit over eastern Canada. This will bring partly
cloudy and cooler conditions Wednesday night into Thursday with
highs Thursday from the low 70s north to the mid 70s south.
The upper trough will continue to dig nearby to our north on Friday
bringing a continuation of unseasonably cool weather to start the
month of August. It will be partly cloudy north to mostly clear
south. Cool air aloft may produce just enough low level instability
for a stray shower across the north on Friday. Otherwise, mainly dry
weather is expected through late week.
&&
.AVIATION /09Z SATURDAY THROUGH WEDNESDAY/...
NEAR TERM: Generally VFR conditions are expected across the
region today through Sunday. However, variable conditions are
possible in any patchy fog overnight. Occasional MVFR
visibilities are also possible this afternoon into tonight with
any smoke/haze. North/northwest winds 10 to 15 knots, becoming
variable 5 to 10 knots today. Variable winds 5 to 10 knots,
becoming south/southwest tonight. Southwest winds 10 to 15 knots
with gusts up to 20 knots Sunday.

&&
.MARINE...
NEAR TERM: Winds/seas below small craft advisory levels today
through Sunday.
SHORT TERM: Light winds and seas of 1 to 2 ft are expected
through the coming week. Humid air over the cooler waters may
result in some mist or patchy fog through mid-week. Drier,
cooler air should then result in good visibility during late
week.
