Area Forecast Discussion
National Weather Service Caribou ME
1259 PM EST Sat Dec 4 2021

.SYNOPSIS...
High pressure will cross the region today. Weak low pressure
from central Canada will cross the region tonight then exit
across the Maritimes Sunday. A warm front from strong low
pressure moving northeast from the upper Great Lakes will lift
across the region Sunday night into Monday. A strong cold front
will cross the region Monday night as the low moves toward
northern Quebec. High pressure will cross the region Tuesday.
Another low from the Midwest will approach later Wednesday.
&&

.NEAR TERM /THROUGH TONIGHT/...
Update...
High pressure will cross the region today. A clipper system will
approach from the west later this afternoon. Generally expect
mostly sunny skies through much of the afternoon. However,
clouds will begin to increase across mostly western areas later
this afternoon in advance of the clipper. High temperatures
this afternoon will range from the upper teens to lower 20s
north, to the mid to upper 20 interior Downeast with around 30
along the Downeast coast. Have updated to adjust for current
conditions along with afternoon temperatures and clouds.

Previous Discussion...
Clds will be on the increase late tdy and erly eve ahead of a
weak clipper s/wv and associated sfc low apchg from Cntrl Can.
Initially, lgt sn will be breaking out ovr NW and W Cntrl ptns
of the FA from the weakening primary sfc low movg into Ern QB,
with another area of lgt sn developing alg the Downeast coast as
a weak secondary sfc low develops alg the Downeast coast. Snfl
in these two areas where we advertise highest likely PoPs will
be arnd an inch with lcly up to 2 inches possible in a low
QPF/high sn ratio environment. Over the Lower Penobscot vly,
Cntrl, and NE ptns of the FA, lesser fcst QPF of 0.01 to 0.03
inches only justified hi chc PoPs with msly less than an 1 inch
accumulation potential. In any event, this is the type of system
that lgt sn/sn shwrs may fall from a thin translucent cld cvr,
which will not allow for much in the way of nocturnal temp rises
inland from the immediate coast.

This fast movg system will exit the FA by daybreak Sun, with at
least partial clrg in the pre-dawn hrs. Subsequently, there
will be a short window for some radiational cooling before
sunrise Sun, making for a tricky fcst of low temps, since with
lgt sfc winds, a sig shallow sfc base invsn may have tm to form
ovr some areas under decent radiational cooling conditions.
&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
Deep layered westerly flow remains across the forecast area on
Sunday as surface high slides east across the region. Forecast
soundings across the north are showing some steeper lapse rates,
with some moisture between H80-H90. Thus expecting a bit more in the
way of mixed cloud and sun north, but mainly sunny downeast. Highs
on Sunday still expected to be 6 to 8 degrees below daily normals.

Surface high slides out into the open Atlantic to the south of Nova
Scotia Sunday night. Upper flow becomes more southwest in response
to upper trof approaching from the west, while surface low
tracks east across the Great Lakes region later Sunday night.
Models still keying on a band of snow developing across far
northern areas later Sunday night in association with a warm
front. This could produce an inch or two of snow across the
north, especially the St. John Valley by daybreak on Monday.
Otherwise, expect central and downeast areas to be mainly cloudy
but dry. Expect slowly rising temperatures overnight, with
increasing clouds and developing southerly flow.

On Monday, deep layered southwest flow is expected in response to an
approaching upper trof. Surface low in the vicinity of the upper
Great Lakes region at 12Z Monday will intensify as it tracks
northeast across Ontario province and into Quebec late Monday
afternoon. Any snow across northern areas will change to rain
showers later Monday morning, with rain showers expected downeast

Southwest flow ahead of the approaching upper trof and surface cold
front will result in an unseasonably warm day on Monday, with highs
topping out in the upper 40s to near 50 degrees north and low to mid
50s downeast. Strong H925 low level jet ahead of the approaching
front will result in increasing wind later Monday afternoon,
especially Downeast. Headlines to address to increasing winds will
likley be needed with subsequent forecast packages for portions
of the forecast area.

Intensifying surface low lifts across to our northeast Monday night
with a strong cold front crossing the region overnight. Expect rain
Monday night as the front crosses the region. The concern heading
into Tuesday morning is that any standing water from Monday night's
rainfall rapidly freezes, as temperatures quickly fall behind
the strong cold front.
&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
Tuesday will be a very cold and blustery day behind the cold front
with high temperatures expected to occur early in the day, with
steady of slowly falling temperatures expected in the strong
cold advection.

High pressure will remain across the region Tuesday night with
mainly clear and cold conditions expected. The high will slide east
early Wednesday.

Low pressure will move northeast from the Mid Atlantic later
Wednesday and then move northeast Wednesday night into Thursday.
Still plenty of uncertainty this far out regarding the exact
track of the low, but this system could bring accumulating snow
to portions of the region later Wednesday into Thursday. High
pressure will build back in on Friday.

Temperatures through mid week will be below normal.
&&

.AVIATION /18Z SATURDAY THROUGH WEDNESDAY/...
NEAR TERM: VFR conditions expected across the region this
afternoon. MVFR conditions develop this evening with light snow
or snow showers, which persist into the early morning hours with
occasional IFR also possible. Variable winds 5 to 10 knots,
becoming southwest this afternoon. Variable winds 5 to 10 knots,
becoming west/northwest tonight.

SHORT TERM:

Sun...VFR. W-NW wind 10 to 15 kt G 20kt.
Sun night...VFR, then becmg IFR in developing snow across the N
terminals. mainly VFR downeast. Light Wind.
Mon...Widespread MVFR/IFR in ocnl rain showers. S to SW wind
increasing to 15 to 25 kt with G35kt or higher vcnty KBHB. Mon
night...MVFR/IFR in rain. SW wind 15 to 25 kt G35kt becmg NW
late. Tue-Tue Night...Mainly VFR. W to NW 10 to 20 kt G 25kt.
Wed...VFR, then MVFR/IFR in developing snow late. NE wind 10 to
15 kt.
&&

.MARINE...
NEAR TERM: Expect conditions below small craft advisory levels
this afternoon. Winds and seas are then xpctd to to increase
back ovr SCA thresholds msly ovr the outer MZs late tonight into
erly Sun morn. Kept close to blended wv model guidance for fcst
wv hts with wvs composed of two spectral groups; a short fetch
4 to 6 sec and a weak open Atlc swell group of arnd 10 sec.

SHORT TERM: SCA conditions are possible Sun. Gale Force winds are
expected Monday and Monday night. SCA conditions expected Tue/Wed.
&&

.TIDES/COASTAL FLOODING...
A period of high astronomical tides will occur from now into
Tuesday. The highest astronomical tide will be on Sunday
morning, but that is not expected to coincide with any storm
surge or significant wave hts. Monday, however, is a different
story. A strong southerly flow is expected to generate storm
surge and waves could increase towards 10 ft. Therefore, there
is potential for coastal flooding and splashover at the Monday
high tide near noon.

ME...None.
MARINE...None.
