Area Forecast Discussion
National Weather Service Caribou ME
427 AM EDT Wed Aug 11 2021

.SYNOPSIS...
A moist, warm south/southwest flow will persist into Saturday.
A cold front will cross the waters Saturday night. High pressure
will build across the region Sunday.

&&

.NEAR TERM /THROUGH TONIGHT/...
Today...
Marine layer has a very strong hold over the forecast area under
low level southerly flow ahead of an approaching warm front. As
of 3am, the only areas spared from the low clouds are the tops
of mountains, areas just to the lee (north) of the larger
mountains, and NW Aroostook. Some drizzle Downeast as well.
Today will feature cooler temperatures than yesterday inland, as
we don't expect the marine layer to dissipate much through the
day...some lifting of clouds, yes, but little sunshine except
for perhaps far NW Aroostook and Northern Somerset. Downeast
will remain in the soup just like yesterday, except with clouds
being even lower than yesterday. Quite muggy with dewpoints in
the 60s, perhaps rising to near 70 late in the day. At least it
won't be too warm (unlike Thursday), with highs Wednesday
generally in the mid 70s inland, except perhaps around 80 in NW
Aroostook where there could be a few peeks of sun, and near 70
for immediate coastal Downeast. Did lower high temperatures a
bit from before. Little or no surface CAPE today for the vast
majority of the area with the strong marine layer. However,
plenty of unstable air and surface CAPE just west of the area
with approaching shortwave trough/vort max, and any storms that
form could hold together to about a Newport to Estcourt line
before fizzling to scattered showers. Trimmed back thunderstorm
area to the west of what we had.

Tonight... Shortwave trough/weak vort max moves through in the
evening with scattered showers areawide. Could be an isolated
storm Downeast as models indicate some CAPE aloft and added in
isolated thunder Downeast for the evening. With these storms not
being surface based and probably not being that impressive to
begin with, not concerned about anything remotely strong. Big
story tonight will be the marine layer that will be extremely
firmly entrenched, likely even lower than the present night.
Bumped up fog tonight, which should be widespread Downeast
though fairly significant inland as well depending on the cloud
base of the marine layer. Another mild night, even milder than
the night before, with lows around 70, except mid 60s along the
coast. Warm front will be moving through overnight which will
set the stage for a hot day Thursday, as well as shift 925/850mb
winds slightly more SW than S, which should help erode the
marine layer inland much faster Thursday than Wednesday.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
The main theme will be hot and humid conditions. The warm upper
ridge in place combined w/the SSW wind on Thursday will bring
hot temps and very humid conditions into the region. Any low
clouds and fog should be scoured out quickly to allow for
sunshine allowing for temps to soar well into the 80s and
possibly the lower 90s. The heat indices are expected to reach
well into the mid 90s to near 100 degrees across a good portion
of the region w/the exception of the Downeast coast due to the
onshore wind off the Gulf of Maine. The decision was to go ahead
and issue a Heat Advisory for Thursday for a majority of the
region w/the exception of the Downeast coast and the far
western areas. An uncomfortable day to the say the least. A
leading short wave ahead of a cold front is expected to slide
across the region Thursday afternoon into the evening w/the
potential for some tstms. As referenced by the daycrew, PWs AOA
2" and Available CAPE along w/decent lapse rates, especially in
the llvls, should be enough to get some storms going. The main
threat will be very heavy rain. However, although the shear is
not overly impressive, any stronger cell that can hit above 35k
ft will be able to bring some gusty winds to the sfc. Attm,
decided against any enhanced wording given the low confidence.
Scattered tstms will carry into the evening and then weaken
overnight. Expecting for fog to develop again w/the fog being
dense in some areas, especially across the Downeast region.
Another item to mention is that Thursday night will be warm
w/the potential of Caribou tying or perhaps setting a record
high low temp. The current record is 71F.

Friday will be another hot and continued humid day w/daytime temps
hitting well into the 80s and once again possibly the lower
90s. We will most likely be dealing w/another round of high heat
indices especially across the Downeast region. The GFS is
touting some very warm 925mb temps in the 26-28C range re-
establishing the warm ridge. The 00Z ECMWF is a bit cooler as it
tries to bring some showers and possible tstms across the
region. There is a pre-frontal trof ahead of the slow moving
cold front in Quebec that is expected to move across the region.
There is instability available, but the challenge w/be
available through 700 mbs. Attm, decided to stay w/the daycrew's
of 20-30% pops for some activity, but not expecting anything
significant. The cold front is expected to make its push into
the region later Friday night w/the threat for some showers and
tstms. The highest chance will be across western and northern
areas. It will be another warm and very humid night w/overnight
low temps in the upper 60s and lower 70s.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
The front is shown by long range guidance including the ECWMF
and GFS to push across the region on Saturday w/the continuation
of showers and tstms. Attm, it is hard to say if some of the
storms will become severe given that shower and tstms set up
Friday night, which could dampen that threat, especially for the
western and northern areas. However, areas further to the east
could have greater instability to allow for some stronger to
possibly severe storms. We'll have to see how things play out as
we move closer in. Definitely a difference in the airmass by the
afternoon w/cooler temps arriving from Canada. High pres is
forecast to build into the region on Sunday and hold right into
early next week w/much more pleasant conditions.

&&

.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
NEAR TERM:
Today... To start the day, we are seeing low MVFR or IFR north
of MLT, and mostly LIFR south of MLT including in BGR and BHB.
Marine layer/low clouds remain entrenched today with BGR/BHB
remaining IFR, perhaps even remaining LIFR BHB. Northern
terminals could improve to MVFR, though VFR unlikely except for
perhaps briefly. S breeze around 10 kt.

Tonight...
Conditions deteriorate after dark. By the end of the night,
should see LIFR areawide in low clouds and fog, with the lowest
ceilings and visibilities likely being in BGR and BHB. Could be
an isolated thunderstorm in the evening around BGR, but wasn't
confident enough to put VCTS in the TAF. S breeze around 5 kt.

SHORT TERM:

Thursday...VFR for all terminals. MVFR/IFR early in the morning
w/fog will be lifting and burning off. SSW winds 5-10 kts.

Thursday night...IFR to LIFR for KBHB and KBGR w/fog and possibly
some drizzle. Further north, VFR but an evening tstm is
possible which could lower conditions to MVFR or even IFR
briefly. Light S wind around 5 kts.

Friday...Any low clouds and fog will lift and burn off by 8 AM
w/VFR for the entire area. SSW winds < 10 kts.

Friday night...Fog developing for KBHB w/IFR and perhaps LIFR.
Generally VFR for the northern sites, but a tstm could drop
conditions briefly to MVFR/IFR as a cold front approaches from
the w. S wind < 10 kts.

Saturday...IFR/LIFR for KBHB early. VFR from KBGR northward.
However, showers and tstms are possible during the day which
could lower conditions to MVFR/IFR. SW wind 5-10 kt becoming
W later in the day w/a cold fropa.

Sunday...VFR across the entire region. NW wind around 10 kt.

&&

.MARINE...
NEAR TERM: Fog over the waters with visibility less than a mile
today and tonight. S/SW wind around 10 kt with seas 1 to 2 feet
today, building slightly to 2 to 3 feet tonight.

SHORT TERM: Fog will be the primary concern Thu right into early
Sat w/vsbys down below 1 NM. This could hamper navigational
interests. A cold front is expected to sweep across the region
by late in the afternoon w/some showers and tstms. This will
lead to improving vsbys. WInds during this timeframe will be SSW
