The episode as NWS BTV wrote it up.
A potent double-barrel low pressure system moved across New York on April 16th. A strong low level east-southeast jet delivered some damaging winds to the western slope communities of Vermont's Green mountains. Numerous trees downed with utility lines downed by fallen trees or branches. Some trees fell on structures that caused some significant damage, including crushing a camp building at the Addison county summer music camp in Leiscester. Approximately 25,000 customers lost power due to the storm.

NWS Burlington, VT wrote its last area forecast discussion before the first event at Apr 1, 6:51 AM EST, 1 hour 9 minutes earlier.
Area Forecast Discussion National Weather Service Burlington VT 751 AM EDT Sun Apr 1 2018 .SYNOPSIS... High pressure returns this afternoon as the lingering showers exit the North Country. Both today and Monday should be quite pleasant even as temperatures trend below normal. The next widespread rain event will move through Tuesday into Wednesday. && .NEAR TERM /THROUGH MONDAY/... As of 743 AM EDT Sunday...The front is just moving into the Champlain Valley and dew points still remain in the mid to upper 30s in the Valley. The light rain will slowly come to an end this morning as the shortwave runs into more dry air. Quick updates were made to the pops and wx grids along with matching current trends in temp dew point. Have a good one. Previous Discussion...The upper level short wave that is bringing showers to the North Country continues to push north and west overnight. With large dewpoint depressions across Vermont locales and the strongest dynamics west of the Adirondacks, most of the forecast area may see some light drizzle but for the most part the reflectivity returns is amounting to virga. The surface cold front is rapidly sweeping across New York and as of 3am is currently located just west of the Saint Lawrence valley but is on the door step. I'd anticipate the front moving through within the next hour of so at MSS. Gusty winds remain the bigger focus as sites continue to report 20-30 mph winds. The CXX VAD shows 45-55kts at 1000ft so we aren't quite seeing the mixing needed to bring that low level jet to the surface. At the higher summits however its quite windy as gusts over 50 kts have been reported at Whiteface and Mt Mansfield. Temps have been tricky as ahead of the cold front warm air advection has continued to push into the region. In areas from the Champlain Valley east well likely not fall nearly as much as anticipated and should stay in the upper 30s to near 40. Then as the front sweeps through during the early morning our daytime high temps will be set at we'll hold steady to slightly cool through the rest of the day. With the cold air advection rushing in we'll start to see better mixing as lapse rates will become quite steep through the morning hours. The good news is the strongest low level jet will be out of the region so I anticipate winds only gusting to 25-35 mph this morning into early afternoon. We'll hold on to some low to mid clouds through the day and then clouds thicken overnight. Anticipate lows this evening cooling sharply but there should be enough wind to mitigate the temps from bottoming out. High pressure continues to build into Monday but temps remain on the cool side as we should only warm in to the upper 30s to low 40s under mostly cloudy skies and westerly winds. && .SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/... As of 341 AM EDT Sunday...Trends in the data suggest Monday night will essentially remain dry and warm frontal precipitation does not really move into the area until later Tuesday morning and especially Tuesday afternoon when precipitation chances essentially become categorical. Temperatures to start the day on Tuesday will be such that precipitation may be in the form of light rain or light snow at the lower elevations and light snow in the mountains. Expecting quite a it of cloud cover on Tuesday to limit high temperatures to the upper 30s and lower 40s. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... As of 341 AM EDT Sunday...Warm front lifts north of the international border by midnight and area should get in the warm sector. Thus feel precipitation will taper off toward midnight and temperatures rise through much of the night. Thus any precipitation will be in the form of rain. Concern on Wednesday will be timing of the front that moves across the region. Looks like it will be across northern New York Wednesday morning and moving across Vermont during the early afternoon hours. Feel clouds and widespread precipitation may preclude temperatures from warming significantly. Have gone with a sharp gradient with highs in the lower 40s across the Saint Lawrence Valley to the lower 50s across the Connecticut River Valley. Majority of precipitation on Wednesday will be in the form of rain with some snow mixing in across northern New York late in the day...but amounts will be light. Strong cold air advection develops Wednesday night and Thursday across the area and highs on Thursday generally in the 30s. Another low pressure system moves into eastern Canada late Thursday night into Friday and should see another burst of precipitation across the area...once again as a mix of rain and snow with highs on Friday in the mid 30s to lower 40s. While it looks like we start drying out Friday night into Saturday it looks like we will still remain in the pattern of below normal temperatures with highs on Saturday in the mid 30s to lower 40s. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... Through 12Z Monday...The aviation concern remains the low level winds and associated shear/turbulence through the early morning although the strongest winds are not out of the North Country. VAD profilers show 925mb to 850mb winds starting to weaken to 25 to 35 knots. MVFR ceilings will briefly continue at SLK but then all sites should be VFR ceilings through the period as broken ceilings turn to few to scatter cloud cover by mid afternoon. Winds will be west/northwest and remain moderately gusty through 18-21z this afternoon. Winds will finally abate during the evening hours Sunday night but should remain westerly 4 to 8 knots. Outlook... Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: Mainly VFR, with areas MVFR possible. Definite RA. Tuesday Night: MVFR. Definite RA. Wednesday: MVFR/IFR conditions possible. Definite RA. Wednesday Night: Mainly VFR, with local MVFR possible. Chance SHSN, Chance SHRA. Thursday: VFR. Slight chance SHSN. && .BTV WATCHES/WARNINGS/ADVISORIES... VT...None.
