What forecasters said that day

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

NWS Gray, ME wrote its last area forecast discussion before this heat advisory went out at Aug 9, 9:20 PM EDT, 5 hours 55 minutes earlier.

Area forecast discussion, Aug 9, 9:20 PM EDT, 5 hours 55 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Gray ME
920 PM EDT Mon Aug 9 2021

.SYNOPSIS...
Humid tonight with fog developing along the coast. The trend
will then be toward heat and humidity during the rest of the
work week. The likelihood of widespread showers and storms
increases through the second half of the week, culminating in a
frontal passage either Friday night or Saturday. This should
bring an end to this latest bout of heat with a Canadian airmass
returning temps to near normal this weekend.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
920 PM Update: Primary changes are to add drizzle along the
coast of ME given evening observations. Also..have increased
shower chances as band of shower activity arcing from FIT to
BOS has been holding together and should bring some showers to
SE NH in agreement with recent HRRR runs. Temperatures look good
through the overnight.

600 PM Update: Have made some adjustments to boost dewpoints and
lower coastal temperatures in line with late afternoon
observations. Also adjusted sky cover to refine area of coastal
stratus. Forecast in good shape for the overnight with VSBYS
likely beginning to fall rapidly along the coast after 8pm in
line with afternoon NARRE-TL and HRRR forecasts.

Previous discussion below...
Onshore flow continues this afternoon into tonight. Some breaks
in the clouds have developed late this afternoon over land, but
expect marine air to remain, leading to developing fog
overnight. Fog will likely be dense in areas, and have issued a
Dense Fog Advisory in anticipation of development. Many forecast
guidance products support the limited visibility tonight,
including many runs of the HRRR.

Precip wise, there may be just enough convergence over the
higher terrain and western mtns for some showers to develop amid
late afternoon heat, but instability is largely absent for more
than an isolated shower.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
Fog deteriorates Tues morning, with remaining cloud cover in
the morning tempering daytime highs. The real heat show arrives
in the extended, more on that below.

Tuesday will be dry with S flow. A weakening warm front
advances from the SW during the afternoon, which will deepen a
fairly saturated layer below a temp inversion. Overnight, not
only will this bring back the chance for patchy fog, there may
also be drizzle to mix in. Opted to go against only having
mention of showers due to dryness aloft, and weak forcing.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Hot and Humid Conditions Expected Wednesday Through Friday...

General pattern in the extended will consist of a sprawling Bermuda
High along the Eastern Seaboard midweek through Friday. This will
lead to well above average temperatures with elevated heat index
values. Relief is expected by the weekend as a 500mb trough
approaches from Quebec on Saturday leading to cooler and less humid
conditions for the end of the weekend. Forecast confidence is above
average in regards to the general synoptic flow.

Southwest flow becomes established by Wednesday kicking out any
remaining marine layer lingering on the coast as offshore flow
becomes dominate. Dewpoints will surge across the entire CWA with a
very sticky airmass as the NBM is showing very little spread
around the 70 degree mark. Confidence continues to increase for
heat advisory levels to be reached across the coastal plain by
Wednesday. Rinse and repeat will be the forecast for Thursday
and Friday with a slight trend up in temperatures on Thursday as
the possible peak in the heat with HI values breaking the
century mark in southern NH and SW ME. The biggest impact for
this heat event will be the longevity of it and the fact that
minimum temps will remain in the 70s for both Thursday and
Friday night. Broad cyclonic flow just to our west will allow
just enough instability aloft to help aid in afternoon
convection each day, with higher props the further north and
west you go. Surface cold front looks to cross the area on
Saturday with more storms, potential for severe weather will be
a good bet based on pattern recognition. A relief is expected
towards the end of the weekend.

.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
Short Term...

Summary: Weak low pressure south of New England and high pressure
over the Canadian maritimes will maintain a moist...onshore flow
across the region through Tuesday with stratus and fog. While this
low will lift north and east of the area Tuesday night...moist
conditions will continue.

Restrictions: Conditions will quickly deteriorate to LIFR along the
coast tonight...with these conditions building inland towards
MHT/CON/AUG overnight with fog developing later further inland at
HIE/LEB. Improvement comes first inland Tuesday morning working it/s
way to the coast during the afternoon with conditions returning to
at least MVFR.  Another round of fog/stratus looks like Tuesday
night although it currently looks less widespread/long-lasting than
tonight.

Winds:  Calm/light southerly winds overnight will remain southerly
less than 10kts for the day on Tuesday before returning to less than
5kts Tuesday night.

Lightning: No lightning is expected through Tuesday night.

LLWS: No LLWS is expected through Tuesday.  Winds around 2kft
increase to 20-25kts from the southwest Tuesday night but currently
look to remain below LLWS thresholds.

Long Term...Wednesday morning IFR conditions could linger along the
coastal TAF terminals but conditions should improve by midday as all
low level stratus will be scoured out of the region with VFR
conditions expected for remainder of Wed. Thursday through Friday
the region will be dominated by high pressure will limited aviation
impacts except for the heat and passing afternoon thunderstorms.

&&

.MARINE...
Short Term...Below SCA criteria, with dense fog tonight. Fog
will again be possible Tuesday evening and overnight.

Long Term...Seas and waves will stay below SCA conditions in the
extended as broad ridging is expected over the coastal waters from
Thursday through Friday. Periods of fog can't be ruled out as a
moist airmass remains over the waters. Cold front is expected by
Saturday which will bring a period of thunderstorms over the waters
with a wind switch to offshore NW flow.
