What forecasters said that day

The local office's own words before this high surf advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Caribou, ME wrote its last area forecast discussion before this high surf advisory went out at Jul 8, 12:50 PM EDT, 3 hours 13 minutes earlier.

Area forecast discussion, Jul 8, 12:50 PM EDT, 3 hours 13 minutes before
Area Forecast Discussion
National Weather Service Caribou ME
1250 PM EDT Thu Jul 8 2021

.SYNOPSIS...
A cold front has become stationary over the Gulf of Maine
tonight. Low pressure from the Great Lakes approaches this
evening and tracks along the Saint Lawrence valley tonight. Low
pressure from the remnants of Tropical Storm Elsa will approach
from the southwest and track along the coast Friday afternoon
and evening and move into eastern Canada Saturday morning. High
pressure will build into the area from the west into early next
week.

&&

.NEAR TERM /THROUGH TONIGHT/...
1250PM update...Updated sky conditions to reflect greater
clearing across the north early this afternoon. Thicker clouds
moving in now across the North Woods which will drape across
other parts of Aroostook. Scattered showers ongoing across
Downeast, but relatively light. Did bring pops down this
afternoon across the north, slightly later arrival time w/ a
pretty dry column remaining based on morning KCAR sounding.

Prev discussion blo...
Frontal bndry looks to have stalled out just to the south of
our waters, btwn Nantucket and the southwest tip of Nova Scotia
as of 07z. Line of storms mvg thru MA and into sw NH at this
time wl move east thru the remainder of the morning along
instability gradient. Gradient wl likely remain to the south of
the area though cannot rule out an isold shower mvg thru
interior Downeast this morning and wl continue to monitor the
mvmnt of this line.

An inverted trof/sfc bndry is showing signs of dvlpng early this
morning fm sfc low located over nrn Indiana. Sfc ridge axis acrs
FA is gradually being shoved east into Canada, which wl allow
boundary to nose up along the international border late this
afternoon and evening.

Overrunning wl dvlp this afternoon and allow PRE to dvlp acrs
nrn and western areas as upr lvl jet lifts north into Canada,
placing these areas in RRQ. By 00z tonight TS Elsa wl be
nearing the Delmarva with low-level theta-e axis extending up
along the coast and heading nwrd thru the night. Latest guidance
is a little further north with theta-e axis than prior days,
thus hv dropped qpf amnts acrs the North Woods and the St. John
Vly with heaviest amounts just to the north of our area though
cannot rule out it will be right on our border with Canada.

Initially looking at between 1-1.25 inches from the Allagash twd
Madawaska area with a swath of 0.5-1.0 inches over the Central
Highlands and into eastern Aroostook with interior Downeast
areas below 0.50 inches through Friday morning. This wl set the
stage for locally heavy rainfall with post-tropical Elsa in the
short term period.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
Friday and Friday Night...Rain a bigger deal than wind with
Elsa remnants. A bit of a break in rainfall intensity Friday
morning in between the predecessor rain event and the remnants
of Elsa. Still, many areas will see rain continue all the way
through the "break" between the predecessor event and the
remnants of Elsa. Elsa's track has shifted a bit north which
makes flash flooding Friday afternoon and evening a bit more of
a concern for Downeast, along and just north of Elsa's track.
Wasn't quite confident enough on the track of Elsa to issue a
flash flood watch yet, but will be monitoring closely.
Convection allowing models are showing quite intense
precipitation for a few hours just north of Elsa, with the
potential for greater than 2 inches of rain within 6 hours. Not
concerned about any river flooding as rivers are running quite
low. Again, the threat of heaviest rain late Friday with Elsa
appears to be Downeast, but will need to watch closely for any
shifts north or south in track. Winds will be stronger on the
south side of Elsa's track, which means the stronger winds to
around 45 mph should be over the waters, with gusts around 30
mph over land, mainly near the Downeast coast. Little if any
land impacts from the wind. Elsa races out Friday night, with
clearing and drying overnight.

Saturday...Weak high pressure nudges in from the north with a
tranquil day outside of a slight chance of showers near the
coast. Highs in the mid to upper 70s. Somewhat muggy Downeast,
but more comfortable dewpoints up north.

Saturday Night...Weak high pressure persists with a quiet night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
For Sunday into Tuesday, expect pretty strong ridging developing
centered over the mid-Atlantic, with the ridge axis extending up
through New England. Could be a few afternoon showers or storms
each day, but nothing too concentrated. Temperatures warmer than
average. Toward Wednesday and Thursday, some signs of the ridge
weakening with a better chance of showers and storms.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
NEAR TERM: VFR for today before conditions deteriorate to MVFR
after 23z over Downeast terminals and drop to IFR/LIFR after 03z
Friday. Northern terminals likely to drop to MVFR after 23z and
drop to LIFR in moderate-heavy rain after 05z.

SHORT TERM: Friday...Downeast, IFR/LIFR through the day with rain,
heavy at times in the afternoon. Could be an embedded storm.
Breezy mainly in the afternoon from Elsa. North of Downeast
Maine, generally IFR improving to MVFR with a W breeze.

Friday Night...Breezy in the evening Downeast as remnants of
Elsa move through. Wind shifting to the NW. IFR improving some
areas to VFR later in the night, but some fog could persist as
well.

Saturday through Monday...Mainly VFR with light wind. Local
MVFR/IFR possible with localized overnight and early morning
fog.

&&

.MARINE...
NEAR TERM: No headlines expected through Friday morning with
winds approaching marginal conditions on the outer waters
tonight as pressure gradient tightens. Seas will increase to
near 4 feet late tonight in southerly swell.

SHORT TERM: Elsa's remnants moving near or over the waters late
Saturday. This will bring the possibility of gale force winds
and seas to 9 feet Friday afternoon into Friday evening. Winds
diminish below small craft rapidly upon Elsa's exit by late
Friday night. Seas gradually diminish back below 5 feet by late
Saturday. Conditions should then remain below small craft
through Tuesday. Fog possible over the waters through the
period.

issues in areas with poor drainage.
