The episode as NWS CAR wrote it up.
Hot humid conditions occurred during the 9th. A surface trof and upper level disturbance crossed the region during the afternoon. Diurnal instability...along with support from the trof and upper disturbance...led to the development of afternoon thunderstorms which persisted into the evening. Some of the storms reached severe levels producing large hail and damaging winds. The most extensive severe storms occurred across Downeast areas.

NWS Caribou, ME wrote its last area forecast discussion before the first event at Jul 9, 12:46 PM EST, 2 hours 14 minutes earlier.
Area Forecast Discussion National Weather Service Caribou ME 146 PM EDT Tue Jul 9 2024 .SYNOPSIS... A weak surface trough crosses the area today. Low pressure then approaches from the west Wednesday through the end of the week. && .NEAR TERM /THROUGH TONIGHT/... 145 PM Update: Current radar reflectivity shows that isolated showers and storms have begun to develop this afternoon as surface inversions finally mix out. These showers will grow in number through the rest of the afternoon prior to the weak FROPA early this evening. Previous Discussion: Another very warm and humid day is expected again today. Afternoon highs will climb well into the 80s in most areas away from the coast. Cant rule out a few highs hitting the 90 degree mark for the Bangor region and Central Maine highlands. Heat indices are expected to reach into the low 90s, just shy of heat advisory criteria in those locations. Even so, it will feel rather oppressive with dew points in the upper 60s to near 70 degrees. Partly sunny skies are expected today with patchy early morning fog expected. The fog will be more widespread near the coast before gradually burning off by mid morning. A mid/upper level disturbance will approach and cross the region later this afternoon through early this evening. As it does so, scattered showers and thunderstorms are expected this afternoon. Latest CAMs continuing to suggest a few stronger storms are possible later this afternoon through early this evening. CAMs continue to hint that any stronger storms may move eastward across the Bangor region by late afternoon. This lines up well with SPCs day one outlook for marginal threat. Although cant rule out a stronger storm or two farther north too. Considering the fairly robust mid level flow, any taller storms could produce some gusty winds. Precipitable water values will be increasing to around or greater than 1.5", thus some locally heavy downpours are possible as well. Any early evening showers or thunderstorms will be winding down early tonight. Otherwise expect partly to mostly cloudy skies overnight along with patchy to areas of fog, especially in areas that receive rainfall today. Once again, lows are only expected to fall into the mid to upper 60s. Combined with dew point sin the 60s it will continue to feel rather uncomfortable. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... Wednesday morning will be the calm before the storm. The remnants of Beryl likely to be somewhere near the IN/OH state line with warm front draped from there acrs the southern tier of NY state. CWA will be under the influence of a very brief ridge axis extending down from high pres over James Bay. This should help keep the lowest levels dry with only chc pops fcst over the Central Highlands into srn Aroostook. High temperatures on Wed will likely climb into the 80s over most locations with dwpts around 70s over central and srn areas. Fairly dry high pressure will keep dwpts acrs the north in the lwr 60s before high starts to lose it/s grip. Wednesday night will see the heaviest rainfall from Beryl/s remnants as very dynamical forcing exists over parts of the area. 00z guidance sets up warm front just north of the Downeast coast. Lift over boundary will be enhanced by RRQ of 140+ knot jet over central and areas. With PW values approaching record maximum values and with warm cloud depths > 12.000 feet expect that locally heavy rainfall will be common during the overnight hours on Wednesday night, especially with any convection that can develop and chances look good that there will be some thunder to the south and right along the warm front. Record pw values from SPC/s sounding climatology page are 2.34 inches from GYX during the record flooding in New England last July. Forecasted GFS pw values for Wednesday night range from 2.3 to 2.4 inches with NAM ranging from 2.3-2.35 inches. Soil moisture is from 98-100% acrs the north and ranges from 90-98% from the Central Highlands over to srn Aroostook. Streamflows are at 90-95% of normal acrs the north to around 50% of normal over central areas. Will continue to monitor but Flood Watches cannot be ruled out as locally heavy rainfall looks likely. Storm total rainfall looks to range between 0.5-0.75" on the coast and over the St. John Valley with local maximums of amounts approaching 2" over the Central Highlands. Keep in mind that these are basin average amounts and does not account for point specific rainfall amounts. The heaviest rain looks to end Thursday morning but pw values look to hang above 2.25 inches over Downeast so cannot rule out locally heavy rainfall during the day Thursday. However the crux of the event looks to occur Wednesday night given the current guidance. && .LONG TERM /FRIDAY THROUGH TUESDAY/... The long term will feature CWA remaining in sw flow aloft thru the early part of the weekend. Upr low that absorbed what remained of Beryl looks to cross the state at some point over the weekend with brief upr ridge influencing the weather thru the latter half of the weekend. Bermuda high looks to continue to pump moisture over Downeast at least through Friday before it gets squashed to the south on Saturday. Unsettled pattern will continue into early next week with no relief in site from the heat and humidity. && .AVIATION /17Z TUESDAY THROUGH SATURDAY/... NEAR TERM: KFVE/KCAR/KPQI/KHUL: VFR will continue through this afternoon. There is also the threat of a scattered thunderstorms this afternoon through early this evening. VFR tonight, except local IFR in patchy fog possible once again, mainly after 06Z and most likely around terminals which receive afternoon rain. SW wind 5 to 10 kt through tonight, except locally higher gusts in the vicinity of any thunderstorms. KBGR: Mostly VFR to continue through the afternoon. Scattered thunderstorms are expected 19z-01Z with brief MVFR or lower conditions possible in any thunderstorms. VFR early this evening, then IFR expected in patchy fog after 03Z. SW wind 5 to 10 kt through tonight, except locally higher in the vicinity of any thunderstorms. KBHB: VFR conditions continue through this afternoon. IFR/LIFR expected to develop again after 00Z in low clouds/fog. S to SW wind 5 to 10 kt through tonight. SHORT TERM: Wednesday...Mainly VFR. W 5-10kts. Wednesday night-Thursday...MVFR/IFR in rain, possibly heavy at times, and thunderstorms. Light E northern terminals and light SE Downeast terminals Wednesday night. E/SE 5-10kts Thursday. Thursday night-Saturday...MVFR/IFR at times throughout the period. Rain and fog look to be likely. E/SE 5-10kts Thursday night, WSW 5-10kts Friday through Saturday. && .MARINE... NEAR TERM: Winds/seas are expected to remain below SCA levels through tonight. Areas of fog will reduce visibility to less than 1 NM at times early this morning and again tonight. SHORT TERM: Winds and seas will remain below small craft levels Wednesday and Thursday. Seas and winds will approach small craft Friday morning into the day on Saturday over the outer waters. Visibilities will continue to be reduced in fog as warm air remains over cold water. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None.
