The episode as NWS CAR wrote it up.
Severe drought developed across northern Aroostook county during early July and persisted through the remainder of the month. In Caribou...July was the 2nd warmest July on record. July was also the 2nd all-time warmest month in Caribou since records began in 1939. This continued a trend from June. The combined 2-month June-July period was the all-time warmest in Caribou. Dry conditions occurred along with the warm temperatures during June and July. The combined 2-month June-July period was the 3rd driest on record in Caribou. Precipitation was mostly in the form of showers and thunderstorms which produced localized precipitation. The Saint John Valley in particular missed many of the showers and thunderstorms. The 60 to 90 day rain totals across northern Aroostook county were as low as 25 to 50 percent of normal. Near record low stream flows were reported across Aroostook county...particularly early in the month. The dry conditions impacted agricultural interests with reduced yields of hay and grain crops. Increased irrigation was required for potatoes and other crops.

NWS Caribou, ME wrote its last area forecast discussion before the first event at Jul 6, 10:07 PM EST, 1 hour 53 minutes earlier.
Area Forecast Discussion National Weather Service Caribou ME 1107 PM EDT Mon Jul 6 2020 .SYNOPSIS... High pressure will build over the area overnight then move southeast of the region on Tuesday. A warm front will lift across the area late Tuesday night into Wednesday. High pressure will return on Thursday. Low pressure will approach from the south on Friday and track across the area Saturday. A trough of low pressure will be over the region Sunday. && .NEAR TERM /THROUGH TUESDAY/... 1045 PM Update: The sky needed a slight adjustment to include some cloud development later tonight w/the upper low in NB. 00Z UA showed 850mb moisture w/a weak trof just n of the border. This feature is shown by the NBM, RAP and NAM to slide across the region to aid in some convergence allowing for the clouds. SREF and HREF guidance pointing to potential for some patchy fog overnight. Decided to add this to the forecast especially Downeast and eastern areas. Hrly temps/dewpoints were adjusted to match the later conditions w/the cooldown. Previous Discussion... Clouds hv diminished over most of the area late this aftn though retrograding low over the Bathurst area of NB has allowed cu to back into nern Aroostook County. Expect this wl rmn over the region and slowly spread back to the west. Patchy fog is expected once again along with low clouds dvlpng along the coast overnight. Winds should be fairly calm and cannot rule out patchy vly fog by morning. Mins wl drop into the u40s acrs the north but rmn in the 50s over Downeast zones. Tomorrow wl be a quiet day with srly winds drawing in warmer and more humid air. Temps right along the coast likely to be stuck in the 60s with outer islands possibly struggling to get into the 60s. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... High pressure will slide southeast of the area Tuesday night as a fast moving shortwave trough and associated surface warm front approaches from just north of the Great Lakes. A moderately strong southerly gradient will likely lift low clouds and cool marine air north across the region Tuesday night. Showers will push into the north late Tuesday night into Wednesday as a function of dynamic lift and some isolated elevated convection. Showers will taper off Wednesday evening as the warm front continues northeast of the region. A south wind and low level moisture will likely result in low clouds lingering much of the day Wednesday even after the rain tapers off. Weak high pressure will gradually build over the area Wednesday night into Thursday. Differential flow involving a southerly wind near the surface and westerly winds aloft may allow some stray thunderstorms to pop up late Thursday, mainly over central and western areas. Otherwise, Thursday will be partly sunny, warm and humid across the area as weak upper level shortwave ridging builds over. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... It's looking like a generally wetter pattern late this week into early next week with several opportunities for rainfall coming as a trough develops to our west and subtropical moisture gets pulled north. Our focus Thursday night into Friday will be on the trough digging to our west as a subtropical low lifts north along the Mid- Atlantic coast. Moisture pushing north ahead of this low may bring some showers and spotty thunderstorms across the area Friday, mainly over the west. The forecast challenge later Friday into Saturday will be where the subtropical low tracks. The potential for enhanced and possibly heavy rainfall will occur along the track of this low across the area, possibly Friday night into Saturday if the GFS is right, or later Saturday into Saturday evening if the ECMWF is right. A secondary shortwave low rounding the trough and lifting up across our area will bring another chance for some more organized showers on Sunday. Yet another shortwave low may lift north to enhance a chance of showers Monday into Tuesday. && .AVIATION /02Z TUESDAY THROUGH SATURDAY/... NEAR TERM: VFR expected this afternoon into this evening. May see MVFR/IFR vsbys at FVE, PQI and HUL develop after 08z as winds go calm. BGR likely to see MVFR vsbys with potential for MVFR clouds but have opted to go SCT025 due to low confidence. BHB seeing IFR between 05-12z in the morning. Al sites becoming VFR after 12z with SSE winds around 5kts. SHORT TERM: Tuesday night: IFR, South wind. Wednesday: IFR, possibly becoming MVFR north late afternoon. South wind. Wednesday night: MVFR to VFR north. MVFR Downeast. Light and variable wind. Thursday: VFR, except lower in any spotty showers. Light S wind. Thursday night: MVFR to IFR Downeast. VFR to MVFR north. South wind. Friday: MVFR. South wind. Friday night: IFR Downeast in rain. MVFR becoming IFR north. Saturday: IFR in rain. South wind. && .MARINE... NEAR TERM: Winds and seas remain below SCA through tomorrow. Patchy fog after midnight tonight will reduce visibilities to between 1 to 3 NM. SHORT TERM: Wind and seas should remain below SCA through the week. Humid air lifting north over the waters will likely result in some fog limiting visibilities. A southerly fetch off the New England coast through mid-week may build seas up to around 4 ft across the offshore waters later Wednesday into Wednesday night. && .CAR WATCHES/WARNINGS/ADVISORIES...
