The local office's own words before the first event, 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 the first event at Jun 28, 1:35 PM EST, 2 hours 40 minutes earlier.
Area Forecast Discussion National Weather Service Gray ME 235 PM EDT TUE JUN 28 2016 .SYNOPSIS... High pressure offshore will allow a more humid air mass to move into the region on a southerly wind. A slow moving cold front approaching from the west will bring scattered showers and thunderstorms through Wednesday. The front will exit the region Wednesday night allowing a return to fair and dry weather. A cold front will cross the region Saturday and could produce scattered showers and thunderstorms. High pressure builds in Sunday and Monday. && .NEAR TERM /TONIGHT/... Greatest instability remains over northern areas which received nearly full sunshine today. Precipitable water values have peaked out greater than one inch in mountain areas in area of best dynamics in close proximity to the stationary surface front and back flow aloft associated with the upper level low. CAPE values in this region remain around 1000 J/KG. Will continue with enhanced wording over northern areas through this evening. Over southern counties, a stable profile will continue with patchy drizzle and fog and a chance of showers. && .SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/... QPF will be highest in the north and mountains tonight through Wednesday as the best dynamics remain over the northwestern portions of the forecast area. There will be a wind shift late in the day, mainly aloft, however still expect scattered showers and possibly a thunderstorm. Highs will be mainly in the 70s, except a pocket of low 80s can be expected over south-central NH. A westerly flow will develop both at the surface and aloft for Wednesday night, returning a more continental airmass to Maine and New Hampshire. Gradient may not be sufficient enough to prevent some patchy fog from forming, especially in areas that received heavy rainfall. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... Hazardous weather threat: Low. A few thunderstorms on Friday night. The long term begins with a strong ridge built into the Canadian Rockies with a weaker trough remaining over Hudson's bay. Short wave will rotate out of James bay around the low. The core of the low will remain to our north through Quebec, before moving to the east as the high pressure slowly shifts east by the end of the forecast period. Thursday will begin as mostly sunny with southerly flow developing. Friday southerly flow will develop helping to push higher dewpoints into the region. Friday night into Saturday the upper level vort max will push eastward driving a surface front and rain into the region. With the front timing overnight at the moment, thunder is less likely but a few rumbles are still possible. Saturday westerly flow develops behind the front with generally clearing conditions. Temperatures will be slightly cooler in the mountains but the most noticeable effect of the front will be a drop in humidity through the day on Saturday. Sunday will be mostly sunny and drier again with high pressure building in for the start of the week. A seabreeze will take over during the afternoon keeping temperatures cooler along the water. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... Short Term...Areas of IFR conditions overnight with isolated LIFR...mainly near and along the coast where patchy drizzle and fog as well as low cloudiness will occur. Showers and storms will also lower the visibility over northern areas as well. Conditions improve to MVFR and VFR on Wednesday. Long Term...VFR conditions look to prevail thru the weekend with isolated to scattered SHRA. Any heavier SHRA may be capable of MVFR or lower conditions...especially as upper low lifts on Thu. && .MARINE... Short Term...No flags. Winds have subsided and seas remain in the 3 to 4 foot range. Long Term...Winds and seas generally look to remain below SCA thresholds. && .HYDROLOGY... Increased precipitable water values and enhanced lift near the stationary front north and west of our forecast area will allow for convection to continue in the mountains. This may allow for a quick inch to two inches of rain per latest WPC discussions and will continue to monitor for flash flood potential. Antecedent conditions do remain very dry for that region. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None. MARINE...None. &&
