The episode as NWS CAR wrote it up.
A combination of heavy rain and snow melt led to minor flooding along portions of the Mattawamkeag River. The river crested less than a half foot above flood stage. Minor flooding persisted into the morning of the 3rd. The flooding was minor...mostly impacting low land areas along the river. This was a continuation of flooding which began on March 31st.
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 Caribou, ME wrote its last area forecast discussion before the first event at Mar 31, 10:22 PM EST, 1 hour 38 minutes earlier.
Area Forecast Discussion National Weather Service Caribou ME 1122 PM EDT Sun Mar 31 2024 .SYNOPSIS... High pressure will drift southeast of Nova Scotia through Monday. A weak disturbance will slide southeast out of Quebec into Maine on Monday night. A large storm system develops over the Great Lakes on Tuesday. This system will give way to a new low pressure along the east coast midweek and tracks north to New England by late week. && .NEAR TERM /THROUGH MONDAY/... 11:20 PM Update...The sky is clear across the area with temps in the mid 20s north to the low and mid 30s Downeast. No significant changes were needed to the forecast overnight. Previous Discussion: A weak ridge over New England with surface high pressure will drift southeast of the Gulf of Maine tonight into tomorrow. Clouds this evening will dry up as the 850mb moisture dries and expecting a trend to mainly clear skies. Tonight, expecting winds to relax and decouple in most locations across the north and Central Highlands. Given the snowpack across the north expecting temperatures to drop into the teens for most locations from Moosehead to Baxter to the St. John Valley including the North Woods and Route 1 corridor. Lows tomorrow will bottom out in the 20-25F range across the Central Highlands to Greater Bangor region and down into Interior Downeast including Calais. Along the shore expecting lows in the mid to upper 20s. It will be a good night for stargazing although on the chilly side... Tomorrow, expecting a disturbance to track southeast from Quebec into Maine during the afternoon. Expect a sunny morning to become partly sunny in the afternoon into early evening. Expecting isolated to scattered rain/snow showers to develop across the Moosehead Region into the North Woods by late afternoon and into the evening. Temperatures tomorrow are much warmer across the area with the weak return flow on the backside of high pressure. Expecting highs into the upper 40s to perhaps a couple 50F readings across the Downeast Coast, Bangor Region into the Central Highlands. Across the Moosehead Region to Baxter up into The County expect low to mid 40s. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... Monday evening another piece of shortwave energy dives southeast through Central Quebec into Northern Maine. Operational runs are differing some with how much precip is available. Typically these are generally moisture starved systems but GFS operational is continuing to suggest up to 0.25" liquid which seems too high for this type of system. This is potent energy so expecting cloud cover for most locations with isolated to scattered rain/snow showers becoming snow showers across mainly the mountains from Moosehead to Baxter into the North Woods. Mainly mostly cloudy across the area. Expect some clearing across the north as the 500mb low tracks over the area with the drying of the lower levels. Tue AM lows look to bottom out in the upper teens to low 20s across the north, mid to upper 20s in the Central Highlands & Moosehead Region with 30-33F lows along the Downeast coast and Bangor region. Tuesday will feature that shortwave being elongated over New Brunswick and Maine because of the strong North Atlantic blocking (-NAO) which will keep partly to mostly sunny skies. 500mb ridging axis works into western New England which will keep the day as dry but moisture advection aloft will turn skies milky by late day. Tuesday night will remain dry with latest operational trends showing stronger North Atlantic blocking than previously expected. This trend has been noted so opted to back up POPs into the day Wednesday keeping Tue Night mainly dry and mostly cloudy. Winds will be northeast 5-15mph with cooler Maritime air working into the area. Expect lows down in to the mid to upper 20s with 30F at the shore and low 20s in the North Woods. Wednesday remains such a model challenge with our large storm system in the Great Lakes giving way to East Coast cyclogenesis near the Delmarva Peninsula. Moisture will be pushing northeastward into New England and likely southern Maine. At the same time with strong North Atlantic blocking and surface high pressure expecting dry air in the boundary layer to be pushing southwestward into the CWA. Intially precip working northeast will likely be Virga but the overall trend is increasing POPs throughout the afternoon. Any precip will be light falling into a dry and warmer boundary layer likely meaning rain/snow mix Downeast and Central Highlands with perhaps snow north. Warmest highs likely across the St. John Valley and Northeast Aroostook where the sun holds on the most. Expect in there areas upper 30s to around 40F. Otherwise mainly mid 30s across the Central Highlands, Moosehead Region down to the Downeast coast. E-NE winds will gradually increase throughout the day with some gusts reaching 20-25mph by late day. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... Low pressure developing along the East Coast will move towards the Gulf of Maine to start the long-term period. Most of the precipitation with this system will occur Wednesday night through Thursday night. However, given the slow movement of this system, some showery precipitation is likely to linger at least through Friday. Significant impacts are possible with this system. However, there is still a fairly large model spread with the track of this system. This will have implications as to the type and amounts of precipitation over the region. The GFS and its ensembles remain the furthest north with this system, tracking it close to the coast before slowly moving eastward into the Gulf of Maine. This would bring heavy snow to central and northern portions of the area, especially the highlands. Snow would change to a rain/snow mix in the Bangor region and Downeast, perhaps even to all rain at the coast. The CMC and its ensembles are further south, tracking the system eastward off of Cape Cod. This would bring the heaviest snow from the Central Highlands southward, with only light snow in the North. The 12z ECMWF and its ensemble suite trended closer to the GFS, though still is not quite as far north. Given the current state of model guidance, had enough confidence to go with at least likely PoPs regionwide, with categorical PoPs for Bangor and Downeast. Kept p-type all snow for central and northern areas through Thursday night. Went with a mix of rain and snow for Bangor and Downeast during the day Thursday to account for track uncertainty as well as the higher early April sun angle. P-type changes back to snow everywhere Thursday night before tapering to snow showers by daybreak Friday. Snow showers could mix with or change to rain showers regionwide on Friday thanks to the lighter rates and temperatures rising above freezing. The snow with this system will be of a heavy, wet consistency, which could lead to power issues. Strong winds are also possible with this system, but exact speeds will depend on the track of the low. The system will be slow to pull away to the east. Thus, not out of the question a few snow showers could hang around Friday night or even Saturday morning. Thereafter, high pressure will build into the region. This will result in dry weather later Saturday into Sunday with moderating temperatures. && .AVIATION /04Z MONDAY THROUGH FRIDAY/...

Seas generally 2-4ft this evening becoming 1-3ft tomorrow. SHORT TERM: Winds/seas remain below SCA conditions through Tuesday evening. Generally E-NE winds less than 15kts. Seas mainly 1-2ft. Late Tue night into Wed AM as low pressure deepens south of the waters expect E winds to rapidly increase to SCA Wed becoming easterly Gales by Wed evening. Seas generally 2-5ft Wed AM will build 6-9ft by late day. Easterly Gales expected to last into Fri AM with gusts up to 45kt. Max wave heights could reach 10-15ft on Thurs before slowly subsiding into Fri. Winds return to SCA conditions on Fri. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None.
