The episode as NWS GYX wrote it up.
Numerous showers and thunderstorms developed under the influence of an upper level low on the afternoon of the 8th. An area of localized convection along the Midcoast brought heavy rain to Knox County. Observations taken near Camden Maine recorded instantaneous rain rates up to 3 an hour, accumulating approximately 1.5 inches|in an hour. The heavy rainfall rates resulted in two road washouts in the Camden area.

NWS Gray, ME wrote its last area forecast discussion before the first event at Jun 8, 9:01 AM EST, 5 hours 9 minutes earlier.
Area Forecast Discussion National Weather Service Gray ME 1001 AM EDT Sat Jun 8 2024 .SYNOPSIS... An upper low moving overhead will bring chances of showers and few thunderstorms today, especially during the afternoon hours. Somewhat unsettled weather remains possible into midweek as upper level lows remain persistent over the region. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 10 AM Update...No big adjustments to the going forecast for this afternoon as upper level low pressure and attendant -20C H5 temps move overhead. This will aid in the gradual development of convective showers with isold thunder. Otherwise, gusty westerly winds of 20 to 25 mph are likely, especially across southern NH. Previously... Update... Have expanded the coverage for fog across the region. Patchy dense fog will continue over southern sections of Maine. Otherwise, only minor edits to the near term portion of the forecast. Have issued an SPS for the slow travel this morning. Prev Disc... Persistent showers and thunderstorms training over portions of Franklin County and perhaps into northernmost Oxford County has prompted a Flood Advisory for the region for the overnight hours. Radar estimates were in the 2-3 inch range over a small portion of the region northwest of Weld and Roxbury. A large scale upper level trough will remain over the region today. A slightly drier westerly flow will allow for more sunshine today than yesterday. However, this daytime warming will allow for diurnally driven scattered showers today, especially this afternoon. Models suggest a few thunderstorms as well this afternoon, primarily over northern areas. The westerly flow will allow for temperatures to be mild in southern areas including the coast. Afternoon high will reach the 70s with the exception of the mountains and the Midcoast region of Maine which will be limited to the 60s. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/... A couple showers may linger tonight, however a brief period of ridging aloft may limit any precipitation. Overnight lows will drop into the 50s in all areas with chilly readings in the northern mountains. Yet another trough will cross the region on Sunday. This will lead to another increased chance for showers especially over the northern mountains. After instability will occur once again therefore a thunderstorm or two cannot be ruled out. It will be slightly cooler with high temperatures mainly in the 60s to lower 70s. Warmest temperatures will be over southernmost New Hampshire. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... Previously... The overall pattern across the northeast in the extended will continue to consist of moist cyclonic flow due to upper level low pressure lingering across the northeast US and southeast Canada. This will lead to unsettled weather at times. But at this time it does not look like there will be any washouts, just mainly chancy to low likely PoPs for showers and thunderstorms, peaking in the afternoons with diurnal heating. This will be mainly true Sunday through Monday before a period of ridging possibly moves in. Highest PoPs each day are in the mountains, with lesser PoPs in southern NH where it could be dry most of the time. Midweek looks drier but there will still be the threat for diurnal showers. Temperatures each day will be in the 70s for most folks, with 60s in the mountains. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/... Short Term...IFR conditions will gradually improve today to VFR as a drier westerly flow enters the region. There will be scattered showers however and possibly a thunderstorm mainly across the north today and Sunday. This will lead to brief periods of IFR conditions. Long Term...Local IFR to MVFR conditions possible Sunday morning at coastal terminals. Otherwise, local MVFR conditions in showers and isolated thunderstorms Sunday afternoon and again Monday afternoon. Some nighttime fog possible, especially where it rained the previous daytime. && .MARINE... Short Term...Conditions hazardous to small craft are not expected through Sunday. Some dense fog is likely again this morning, mainly off the Midcoast. Seas will be 3-4ft with some breezy westerly wind gusts approaching 20 kts today. Long Term...Conditions hazardous to small craft are not expected through Tuesday. However, there could be areas of low visibilities in fog. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None. MARINE...None. &&
