.SYNOPSIS...
A cold front will push off the Downeast coast this afternoon.
High pressure will build into the region tonight and will begin
to move into the Maritimes on Sunday. A cold front will cross
the region Monday night.

&&

.NEAR TERM /THROUGH TONIGHT/...
11:20 AM Update. Raised temps a couple degrees again. Expect
temps to rise 3 or 4 more degrees with cold advection limiting
heating a bit this afternoon. The sky should continue to clear
from north to south.

A cold front across northern Maine early this morning will push
south to the Downeast coast this afternoon, and will move
offshore tonight. A weak wave will track along the front and
across parts of the Downeast Region today. High pressure over
Hudson Bay will build into northern Quebec today and into
western Labrador tonight. The ridge will extend south into Maine
tonight.

Isolated showers in far northern Maine will wind down early this
morning. Showers will fall in spots Downeast this morning and
into at least the first half of the afternoon with drier air to
filter in late in the day. The last several runs of the HRRR and
RAP indicate more widespread showers from around Dover-Foxcroft
and Bangor and into much of Hancock County later this morning
into the afternoon. Have increased the PoPs and coverage a bit
today, and it is possible that the PoPs might need to be
increased even further once we get a better handle on just where
the showers will fall. Clouds will give way to breaks of sun
this afternoon as it turns less humid. Across the north, early
clouds and isolated showers and patchy fog will give way a
mostly sunny day with low humidity and a north wind of 10 to 15
mph with a few gusts to 20 to 25 mph. Highs will range from the
mid 60s north to the low 70s in the Greater Bangor area. Clear
and cool tonight with some frost across the colder northwest
valleys. Have added in some patchy frost. It is iffy as to
whether there will be any frost in eastern Aroostook County and
will hold off on any frost headlines for now as patchy frost is
only in the grids for an hour, and only in some of the lower
spots, but this is something that will need to be monitored.
There may also be a bit of fog in the river valleys for an hour
or two around sunrise.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY/...
Fair weather is expected Sunday as high pressure builds across
the area. The high will slide east of the Canadian maritimes
Sunday night. The high will continue to move east on Monday as a
cold front approaches from the west. There will be the chance
for showers across northern and western areas Monday afternoon
in advance of the approaching front. Highs on Sunday will be in
the mid to upper 60s and in the low to mid 60s on Monday.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
The cold front will cross the region Monday night with the
chance for showers. Tuesday will be a dry day with mainly sunny
sky conditions and seasonable temperatures. Continued fair and
seasonable weather is expected Tuesday night and Wednesday.
Thursday is still shaping up as a very warm day as H925 mb
temperatures approach 23 to 24C with high temperatures
potentially climbing well into the 80s. The ridge moves offshore
Friday allowing a southerly flow to transport moisture back
into the region by late week.

&&

.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
NEAR TERM: VFR today at the northern terminals. Brief MVFR
conditions are possible late this morning into mid afternoon at
KBGR and KBHB in clouds and showers. Otherwise, VFR expected
today and tonight. Patchy late night river valley fog possible
just prior to sunrise Sunday morning, which may locally cause
IFR conditions, but they are not expected to be widespread.

SHORT TERM: Generally VFR through the period. The exception will
be Monday night when a cold may bring MVFR/IFR conditions to the
region.

&&

.MARINE...
NEAR TERM: The wind and seas will remain below small craft advisory
levels through tonight.

SHORT TERM: Winds/seas remain below SCA levels through much of
the period.
