The episode as NWS CAR wrote it up.
Severe drought expanded across portions of central and southern Penobscot county...along with Hancock county...during September. Rain totals during the first 10 days of the month were generally less than 0.10 inch Severe drought expanded across these areas during the third week of September and persisted through the remainder of the month. Bangor experienced its driest September on record with only 0.28 inches of rain. This also represented the all time third driest month on record. Record...or near record...low river and stream levels were reported at month's end. Crops were impacted to varying degrees by the drought conditions. Grain crop yields were reduced, with hay at about half of normal. Potatoes...blueberries...apples and other crops were also affected. The impact on the potato crop was dependent on the extent of irrigation. Harvesting of many crops was in progress at months end.

Area Forecast Discussion
National Weather Service Caribou ME
1220 AM EDT Tue Sep 22 2020
.SYNOPSIS...
Hurricane Teddy will pass east of the area Tuesday into Tuesday
night. Weak high pressure slides back into the area on
Wednesday into Thursday. A weak cold front will cross the area
Thursday night. High pressure returns Friday into next weekend.
&&
.NEAR TERM /THROUGH TODAY/...
1215am update: Frost formation continues overnight under clear
skies and light winds. In reviewing the forecast into Monday
night, the biggest change was increasing winds this afternoon
and evening in the Downeast region to include Bangor. A Wind
Advisory may be needed for the coast. With leaves remaining on
the trees, gusts to 40 mph will likely result in some downed
trees and limbs with some power outages resulting. Also trending
up on precipitation amounts and cloud cover later this
afternoon and tonight.
Previous discussion:
Sfc ridge axis leading to sunny skies over the FA this afternoon,
along with light winds and temps warming into the 60s. Meanwhile
Hurricane Teddy continues to head twd the NNE, located approx 170
miles to the east of Bermuda. Outer cloud shield from Teddy is just
now coming into Nova Scotia and is not expected to mv into very far
sern tip of CWA until after 06z tonight. Moclr skies are expected
for most of the area through the bulk of the overnight with min
temps dipping down to around 30F acrs the deeper valleys in the
north with widespread frost expected once again. Rmndr of the region
wl settle into the m/u 30s by morning.
Impacts from Hurricane , or Extratropical, Teddy wl begin to be felt
acrs Washington County and adjacent coastal waters Tuesday morning.
Northeasterly LLJ wl begin to move thru the Bay of Fundy after 09z
and into Downeast by 18z. LLJ wl continue to influence sern zones
beyond end of the period. Cannot rule out a possibly wind advisory
along the coast late Tue afternoon and drg the overnight but wl
allow the mid-shift to take a closer look as models continue to
disagree on extent and strength of low-level jet associated with the
storm.
Rain begins to move in to the Eastport area shortly after 12z,
gradually increasing in areal coverage thru the afternoon hrs. Given
amount of dry air to the north and east there will be a very sharp
gradient in rain acrs the area, with far sern Washington County
seeing between 0.25-0.50" in the afternoon to Danforth in northern
Washington County being lucky to see 0.05 inches. Temps wl be in the
50s acrs this area with temps in the 60s elsewhere acrs the
region.
&&
.SHORT TERM /TONIGHT THROUGH THURSDAY/...
Overall the forecast hasn't really changed with just some minor
adjustments. Tuesday night Hurricane Teddy will be a few hundred
miles southeast of the Downeast coast. As the storm continues
north towards Nova Scotia it is in transition to a mid
latitude cyclone. The influence of the jet stream & trough will
be stretching the precipitation shield over far eastern zones.
There will be a sharp cutoff in precip as you move north &
west. Slight deviations west/east in the track are possible
which can slightly adjust precipitation totals over far eastern
areas. Best chance of beneficial rain Tuesday night into
Wednesday will be across Eastern Washington county. Along with
the rain we will see gusty northeast winds to 40mph into
Wednesday. Across the rest of the area winds will pick up to
20-30mph area wide. Winds in the 20-40mph range pose the
potential for some power outages. Wednesday into Thursday
temperatures will be above average across the forecast area
thanks to Teddy. A weak front will pass through the area
Thursday night but will be dry. Given the warmer and dry
conditions the biggest concerns from Teddy will be a fire danger
threat outlined below.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Fair conditions Thursday night through Saturday night with just
some scattered clouds on any day. There will be an approaching
cold front next weekend into Monday but there is some model
disagreements on timing/duration. Later in the period with a
southerly flow we may run the risk of some low clouds and fog
along the coast. Temperatures throughout the period will be warm
and above average with several places seeing low 70s again.
Morning lows Friday may be cool in the North Woods but over the
next several mornings lows will be in the 40s to low 50s area
wide.
&&
.AVIATION /04Z TUESDAY THROUGH SATURDAY/...
NEAR TERM: VFR next 24 hours. Expect a broken high deck at BHB
by 15z from outer flow from Hurricane Teddy. Northern terminals
will be calm tonight with winds from the north around 5kts by
mid-morning. Southern terminals will SE winds begin to gust to
near 20kts by 14z.
SHORT TERM:
Tue night-Sat. Mainly VFR. N winds 5-15 kts and gusty Tue and
Wed afternoons. W 5-10k ts Thu, becoming light Fri. S 5-10 kts
on Sat.
&&
.MARINE...
NEAR TERM: Seas will increase in serly swell late tonight with
wave heights increasing to 5 to 8 feet. Long period swell on the
order of 16s expected tonight with seas increasing 5 to 11 ft
Tue afternoon. Winds will increase to gale force Tue afternoon
as Hurricane Teddy passes to the east of the Gulf of Maine as
wind field expands.
SHORT TERM: Gale force winds continue into Wednesday morning
before dropping and SCA will likely be needed through the day on
Wed with winds and seas remaining elevated. Waves and winds
will then drop below SCA levels through the end of the period.
&&
.FIRE WEATHER...
Wednesday looks like the day with the greatest fire risk as
skies clear, temperatures climb to near 70F, relative humidity
drops below 40 percent and northwest winds gust in excess of 30
mph. Washington County may not have high risk due to
precipitation from Teddy, but rainfall amounts from Teddy to the
north and west will be little to none. Therefore, fuels could
be receptive.
&&
.TIDES/COASTAL FLOODING...
The high tide Tuesday afternoon around 320 pm and early Wednesday
morning around 4 am looks problematic as long period swell with
a period of 15 seconds will be pounding the coast. Overwash and
erosion will become an issue, thus a coastal flood watch has
been issued from Tue morning until Wed morning. The powerful
long period seas should have ample strength to push large rocks
on roads such as Seawall on MDI.
This watch not only incorporates overwash and erosion, but also
addresses the issue of high surf as waves of 4 to 6 feet break
in the surf zone in long period swell. Perhaps more
importantly, the combination of long period swell and offshore
winds during these high tides could put spectators at
significant risk at popular spots such as Thunder Hole in Acadia
National Park.
&&
.CLIMATE...
Only 0.08" of rain has been observed in Caribou, Maine so far
this September. The all-time driest September was in 1968 when
