Area Forecast Discussion
National Weather Service Caribou ME
1131 AM EDT Sun Jun 6 2021

.SYNOPSIS...
A front will stall across interior Downeast Maine today. High
pressure will build south of the area Monday. Another cold front
will cross the area Tuesday. High pressure will build in from
the northwest Wednesday into Thursday......

......SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
A real toasty of a day expected for Monday w/record temps possible.
The latest NAM/GFS and ECMWF show a trof at the sfc and aloft,
moving across the region during the early part of the day.
Interestingly enough, the GFS wants to bring some light showers
across western and northern areas Monday morning w/the trof. The
latest run of the HRRR does hint as some weak reflectivity
across the north and even across the Penobscot region during the
morning, but this is the earlier runs were dry. The NAMNEST did
show spotty reflectivity, but looking very weak. The
operational 00Z NAM and ECMWF are dry. Therefore, decided to
keep it dry w/the westerly flow aloft and very weak forcing. S
winds will become SW and increase to 10-15 mph w/some higher
gusts. This will bring some hot temperatures to the region by
the afternoon on the leading edge of high pres to the sw. 925MB
temps are progged to reach 25-26C leading to temps in the blyr
to reach into the low/mid 90s, especially inland areas. The SW
wind will bring cooler air in from the Gulf of Maine to cool
coastal sites some. Heat indices to get close to Heat Advisory
criteria w/a few inland sites forecast to reach 94-95F for a
couple of hrs. Dewpoints climbing to 60-65F will make it for a
humid day as well. The daycrew can assess this further today to
see if a headline will be needed. A warm night expected Monday
night and continued humid w/overnight temps in the 60s to around
70.

For Tuesday, a pre-frontal trof moving is expected to move into
the region during the day w/showers and the threat for some
tstms firing up by the afternoon. There is good CAPE forecast to
set up across the region, especially across the Downeast region
w/1000+ joules and modest lapse rates to support tstms. There
is shear forecast to be around 25 kt. The lacking feature is the
depth of available moisture for organized cells. Attm, per
collaboration w/GYX, decided to go w/isold tstms. It will be
another hot day w/temps forecast to be in the upper 80s to lower
90s. The sfc cold front is forecast to slide out of Quebec and
move across the region Tuesday night w/some scattered showers
and perhaps a tstm in the evening. Some cooling behind the front
w/overnight temps dropping back into the 50s. Refreshing from
the last few nights of humid wx.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
The cold front is forecast to stall across the Downeast region
on Wednesday w/the threat for more showers and tstms. There is
some warming in the llvls w/some available sunshine during the
afternoon which will aid in destabilizing the atmosphere and
allowing for possible convection. The main activity will be
across the central and downeast areas. Much colder air set to
arrive into the region Wednesday night w/the GFS touting 925mb
temps to drop down to 3 to 4C across the northern and western
areas by early Thursday morning. This is quite a change from the
last few days. Nw winds are forecast to stay up around 10 mph,
which will help negate any frost potential. High pres is
expected to slide across the region on Thursday w/a much cooler
day as daytime temps in the upper 60s to lower 70s across the
north and west. Central and downeast areas are expected to see
mid 70s. Thursday night could be a chilly night as high pres
slides across the areas and winds drop off. Clear skies and a
good shot for radiational cooling could very well lead to temps
in the valleys to drop into the 30s w/frost a possibility. This
will all depend on the orientation of the high as the latest GFS
does show light SSE winds setting up late Thursday night, which
could offset any frost. We will have to see how this plays out
as we move through the week. Friday looks to be a rather dry day
w/a weak disturbance moving through the region and possibly
kicking off a few light rain showers, but nothing significant.
Shower chances could increase by Saturday as another disturbance
moves through the region in the upper NW flow........
