.SYNOPSIS...
High pressure will move southeast of the region today. A weak
cold front will cross the region tonight. High pressure will
build toward the region Monday. A cold front will approach
Monday night into Tuesday and cross the area Tuesday night
followed by a secondary cold front on Wednesday. High pressure
will build in on Thursday.
&&

.NEAR TERM /THROUGH MONDAY/...
An Air Quality Alert is in effect for the interior Downeast
region today from 6 AM to 11 PM. A Beach Hazards Statement is
in effect for the Downeast coast today. High pressure exits
southeast of Nova Scotia today. A weak cold front will approach
northern areas later today, then cross the region tonight. High
pressure will build toward the region Monday. Aloft, an upper
level disturbance will cross the region early tonight. CAPE
values increase to 500 - 1000 J/kg across northern and central
portions of the forecast area this afternoon. Diurnal
instability, along with the approaching cold front and upper
level disturbance, will help support scattered
showers/thunderstorms across mostly northern and central
portions of the forecast area this afternoon into early tonight.
However, the extent of convection is still uncertain. Lesser
shower/thunderstorm chances will occur Downeast.
Showers/thunderstorms then end overnight. Patchy fog is also
possible Downeast tonight. Expect mostly/partly sunny skies
Monday. High temperatures today will range from the mid to upper
80s north, to the lower 80s interior Downeast. Temperatures
along the Downeast coast will range from the mid 70s to around
80 with onshore winds. Low temperatures tonight will range from
the upper 50s to lower 60s across the forecast area. High
temperatures Monday will range from around 80 to the lower 80s
north, to the mid to upper 80s interior Downeast with around 80
to the mid 80s along the Downeast coast.

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
A weak weather disturbance crossing the area Monday night will work
with some divergence aloft and lingering moisture to bring a chance
for some showers, mainly over the north. A cold front will
slowly press across the area Tuesday into Tuesday night bringing
additional chances for showers and possibly a thunderstorm,
mainly across the north. Divergence aloft between cyclonic flow
south of a trough over Eastern Canada and anticyclonic flow
north of a ridge to our south may continue to add some lift
supporting showers Tuesday into Tuesday night. CAPEs are
progged to be up to around 600 J/KG supporting any convection
that is initiated. A secondary cold front will approach on
Wednesday bringing another chance for a round of showers and
thunderstorms. By Wednesday, westerly winds will have
significantly increased aloft as the large upper low over
Eastern Canada drops further south. This could result in strong,
gusty, and potentially damaging winds in any deep convection as
it pulls momentum down from aloft. Currently, forecast CAPE is
weak across the north but moderate to strong and very deep over
central and southern areas, likely a result of southern areas
having more daytime heating before the front arrives.
&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
Showers and thunderstorms along the front will press
southward Wednesday evening as the front continues south. This
will bring a chance of thunderstorms, some possibly gusty,
across central and Downeast areas Wednesday evening.

A large, cool Canadian high pressure system will slowly press
in from the west Thursday into Friday as the upper trough over
Eastern Canada weakens and slides to the east. This will bring
cool dry weather for the end of the week with highs Thursday in
the low to mid 70s and highs Friday near 70 under mostly sunny
skies. Lows Thursday night and Friday night may drop well into
the 40s north and the 50s south.

The large Canadian high will slide south to a position off the Mid-
Atlantic coast next weekend allowing a return flow behind the high
to advect warmer air north into the area supporting a building
ridge. This will likely sustain dry weather through next weekend
with a warming trend. However, the position of the high to our
south, ridging west well inland across the Appalachians, would
likely prevent much humid air from flowing back north from the
subtropics. This would result in continued low humidity through at
least the start of next weekend.

.AVIATION /07Z SUNDAY THROUGH THURSDAY/...
NEAR TERM: Variable conditions with any showers or
thunderstorms across the region this afternoon into
tonight, also with any patchy fog Downeast tonight. Otherwise,
VFR today through tonight. VFR Monday. Southwest winds 10 to 15
knots with gusts up to around 20 knots today. Southwest winds 5
to 10 knots, becoming northwest tonight. North/northwest winds
10 to 15 knots Monday.

SHORT TERM:
Monday night...VFR except possibly MVFR in any showers or
thunderstorms. Light and variable wind.

Tuesday...VFR except MVFR in any brief showers, mainly over the
north. Light W wind.

Tuesday night...VFR. Light NW wind. Possibly westerly wind shear
late.

Wednesday...VFR, except briefly MVFR or IFR in any
thunderstorms. Potentially strong gusty winds in any storms.
Otherwise, light W winds.

Wednesday night...VFR, except in any storms early in the
evening. NW wind.

Thursday...VFR. NW wind, possibly gusty at times.
&&

.MARINE...
NEAR TERM: Winds/seas below small craft advisory levels today
into Monday. Slight chance of a shower tonight. Patchy fog
tonight into Monday.

SHORT TERM: Wind and seas are expected to be below SCA through
the coming week. Humid air over the waters Monday and Tuesday
may result in some fog and mist across the waters. The air will
trend drier during the second half of the week resulting in good
visibilities with the only potential exception being when smoke
from the Canadian forest fires strays into the Northeast.
