The episode as NWS CAR wrote it up.
Thunderstorms developed across northern Maine during the afternoon and evening of the 5th. An isolated severe thunderstorm tracked from northwest Piscataquis...across northern Penobscot...to southeast Aroostook counties producing damaging winds at times along its track. The storm track across Piscataquis county ran from near Chamberlain Lake...across northern portions of Baxter State Park...to Grand Lake Matagamon where the storm crossed into northern Penobscot county. The storm crossed northern Penobscot county and exited into southeast Aroostook county to the north of Moro Plantation. The storm then tracked across southeast Aroostook county to Littleton where the storm exited across New Brunswick.

NWS Caribou, ME wrote its last area forecast discussion before the first event at Jun 5, 2:58 PM EST, 1 hour 22 minutes earlier.
Area Forecast Discussion National Weather Service Caribou ME 358 PM EDT Thu Jun 5 2025 .SYNOPSIS... A cold front crosses the region this afternoon. The front will stall across the Gulf of Maine tonight into Friday. Low pressure will cross the area Saturday followed by high pressure on Sunday. An upper-level low will set up to the west of Maine for Monday into early next week. && .NEAR TERM /THROUGH FRIDAY/... This evening, convective cells develop and move through the region as a cold front gradually passes over Maine. These cells are currently producing lightning. Sounding analysis shows favorable CAPE, CIN, DCAPE, lapse rates, effective shear, and moisture content for further storm development into this evening, with this risk being confined to the north this afternoon, and the interior Downeast, Bangor region, and Upper Penobscot Valley this afternoon into evening. Northern region roughly has around 1,500 J/kg, and roughly around 2,100 J/kg down south. Coastal areas are not expected to see severe weather due to the stabilizing sea breeze coming off of the Gulf of Maine. These convective cells could bring periods of strong gusts, heavy rain, and potential for some small hail. DCAPE values and dry air aloft in southern areas are especially favorable for gusts, which have begun to be reported in southern regions. Corfidi vectors continue to show a potential for some periods of slow storm motion that could cause some flash flood concerns, especially if storms train over one location. Continue to monitor forecast and practice lightning safety if outdoors at all. Tonight, front passes over Maine and goes into the maritimes. Skies stay overcast, with some isolated rain showers Downeast behind the front. Some wildfire haze moves its way in from the the northwest overnight into tomorrow morning, lingering in northern counties. Potential for some patchy fog over the waters and southern areas, given high humidities and light winds. Soundings indicate favorable inversions in the far northwest portions of Maine, but at this time, not confident that the air will be humid enough for fog development. Brief period of clearing in the north late tonight, which could drop temperatures a degree or two. Overnight lows in the mid-50s in the north, and 60s down south. Front that just passed through Maine is going to stall in the Atlantic, as a low pressure develops to our NW. Looking at some clear skies in the north, with some haze, until clouds move back over the region by afternoon. Some shortwave activity in the Penobscot/Bangor and Downeast region will cause some light rain showers. Max temperatures in the upper 70s tomorrow. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... Zonal flow will be shifting to a more swrly flow as upr trof digs into Quebec. Boundary will be sitting over the area with waves riding along it. At this time it appears the best chance for rain will be late Friday night into Saturday morning. Med range guidance, including the latest GFS/CMC and EC, has cold front dropping south out of Canada in the afternoon. Cannot rule out tstms in warm and humid airmass ahead of the front and will continue with this idea. Latest NAM on the other hand appears to be suffering from convective feedback as tightly wound low heading off of the Delmarva Saturday evening is impacting fropa, including keeping showers in longer and winds out of the northeast. Have disregarded this solution as majority of operational and ensemble model solutions do not show this. Showers will wind down Saturday evening, pulling east into New Brunswick by Sunday morning. Skies will be clearing after midnight with lows dipping into the 40s over the North Woods with locations elsewhere dropping into the lower 40s. High pressure will keep sunny conditions over the area on Sunday with highs around to slightly above normal in the 70s. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... High pressure will remain over the region into early next week. Cannot rule out an isolated shower moving in Monday afternoon but depending on the strength of the ridge and the slow movement of the digging upper low, precip may hold off until Tuesday morning. System looks to move fairly quickly as wave opens up aloft and zips through on Tuesday evening, though given discrepancies have gone with likely pops thru the day Wednesday. Showers look to continue in wrap-around northwest flow thru the end of the period. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... NEAR TERM: KFVE/KCAR/KPQI/KHUL: Potential for thunderstorms at northern terminals this afternoon as convective cells develop and move through the area ahead of a front. These thunderstorms could reduce visibility with heavy rain showers. Generally, however, predominant conditions are VFR. Winds from the S at 5-10 kts, becoming N/NW overnight. KBGR/KBHB: Potential for thunderstorms at KBGR this afternoon into evening as convective cells develop and move through the area ahead of a front. These thunderstorms could reduce visibility with heavy rain showers. Generally, however, predominant conditions are VFR. Winds from the W at 5-10 kts, becoming N/NE by tomorrow. SHORT TERM: Friday night-Saturday...MVFR/IFR in rain and possible storms in the afternoon. SSE 5kts becoming W-SW 5-10kts in the afternoon. Saturday night...MVFR improving to IFR late with showers ending. NW 5-10kts. Sunday-Monday...Mainly VFR. NW 5-10kts, light Sunday night, then SE 5-10kts Monday. Monday night-Tuesday...VFR/MVFR dropping to IFR late Monday night in showers. S 5-10kts. && .MARINE... NEAR TERM: Winds and seas remain below Small Craft conditions tonight into tomorrow. Seas at or below 3ft over the waters. Winds from the S, becoming E/SE tomorrow. Rain showers tonight into tomorrow. Potential for some patchy fog overnight. More rain showers begin tomorrow, and continue through the weekend. SHORT TERM: Winds remain below sca levels into early next week. Seas climb above 5ft over the outer waters Sunday afternoon into the evening hours in southerly swell. && .CLIMATE... Hot weather continues today with a few sites possibly approaching daily record highs within the next hour. Temperatures will drop into a more seasonable range tonight.
