The episode as NWS BOX wrote it up.
An isolated severe thunderstorm formed overnight in eastern MA, along a stalled front and in association with the nose of a low- and mid-level jet.
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 Boston/Norton, MA wrote its last area forecast discussion before the first event at Jul 8, 2:29 AM EST, 26 minutes earlier.
Area Forecast Discussion National Weather Service Boston/Norton MA 329 AM EDT Thu Jul 8 2021 .SYNOPSIS... A stalled front over southern New England Thursday will be a focus for showers and thunderstorms, especially across CT and western-central MA. Also cooler temperatures are expected given mostly cloudy conditions. Heavy rainfall late Thursday night through Friday afternoon will introduce the potential for localized flooding across southern New England as Elsa, or its remnants, moves across the region. Unsettled weather in the form of scattered showers/thunderstorms may linger into Sat, especially over RI and eastern MA. Although a drying trend should follow for Sunday. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... 230 AM update... Convection firing on nose of developing low to mid level jet across CT into western-central. Low risk for an isolated severe storm early this morning, with strong winds and large hail the main threat. Secondary concern is isolated minor flooding with PWATs near 2 inches. Although, storms are progressive and training doesn't seem to be an issue. Otherwise, frontal boundary continues to slowly sag southward with wind shift to the northeast across much of the region now, with the exception the south coast. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/... 230 AM update... After 10z... Anomalous setup for early July with 1022 mb high over southeast Quebec at 12z Thu, providing cool air damming signature across southern New England! Next mid level short wave approaches from the southwest, and this begins to lift the frontal boundary northward as a warm front. This mid level short wave will initiate a new area of convection early this afternoon, first emerging out of southeast NY and then into western CT/MA after 1 pm. Severity of convection hinges on how far northeast does warm sector tracks. Based on CAMs low level instability, warm sector penetrates into CT and possibly southwest MA, I-91 corridor westward to the NY border. This is the area for concern, strong to severe storms and given anomalous boundary in place, a low risk of tornadoes exists. 00z HREF also highlighting this area (I-91 corridor westward to NY border) with impressive 2-5km updraft helocity and max updraft. Therefore, will insert enhanced wording across this region with risk of strong to damaging winds, large hail and low risk of isolated tornado. Farther east into the cool sector across RI and eastern MA, afternoon convection should weaken with isolated risk of minor flooding give anomalous PWATs. Should be a period of dry weather after this early morning convection exits, with mid level dry air overspreading the region as seen in a decrease in PWATs and K indices roughly 12-18z. Then convection overspreads the area after 18z west to east. In fact, some of the guidance indicates afternoon convection may weaken entirely before reaching RI and eastern MA, especially southeast MA. Cooler today given NE flow and cloud cover. Tonight and Friday... *** Flood Watch Tonight into Friday *** *** Damaging winds & power outages possible *** Evening convection weakens and lifts northeast with departing mid level speed max. However, moisture from Elsa begins to stream NE and combines with RRQ of upper level jet streak over southeast Canada, along with leftover surface boundary over SNE, yielding Elsa's rain shield expanding NE and intensifying. Good model agreement that Elsa circulation will track along or near the I-95 corridor of eastern CT-RI into eastern MA Fri morning and early afternoon. Strong heavy rain/flood signal in the guidance especially HREF with 20-30% chance of 6 hr qpf exceeding 3 inches 12z-18z Fri across CT into western-central MA! In addition, HREF 48 hr mean qpf in this region is 4-5"! So given tropical connection, leftover low level boundary and RRQ of upper level jet streak, will hoist a Flood Watch for tonight into Fri from the I-95 corridor westward. Also, given track of Elsa across the I-95 corridor of eastern CT-RI and eastern MA, impressive low level circulation with multi model 925 mb winds 50-60 kt (up to 80 kt on EC!) across RI and eastern MA 12z-18z Fri. Winds of this magnitude only 3 kft AGL combined with tropical convective feeder bands, strong signal for damaging winds and power outages, especially with surface winds from the southeast. This is a direction that tends to produces tree damage given the low frequency of occurrence. Therefore will provide enhanced wording in our products and discussions to message this increased wind threat Fri. Models have also trended faster with Elsa's departure, therefore rain may taper off from west to east Fri afternoon. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Saturday through Wednesday Seasonable temperatures and unsettled conditions forecast through the weekend and early next week. A persistent Bermuda high continues to pump warm moist air into southern New England from the southwest. Meanwhile an upper-level trough at 500 hPa will be digging into the Midwest early next week. Latest model guidance suggests that embedded short-waves downstream the trough axis will produce the forcing necessary for some isolated to scattered showers each afternoon through Wednesday. There will also be the potential for some diurnal thunderstorm activity as there should at lest be some instability to work with during the afternoon hours. Daily low/high temperatures in the 60s/ upper 70s-lower 80s respectively each day. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... Forecaster Confidence Levels. Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. 0730z update... Thru 12z...Moderate confidence. Thunderstorms with frequent lightning moving across RI into Worcester Hills at 0730z will continue to march eastward and should exit offshore by 09/10z. Isolated strong wind and hail threat until then along with brief heavy rain. Mainly VFR but areas of IFR in low clouds and fog. Light N-NE winds continue. After 12z...moderate confidence. A mix of VFR/MVFR with mainly dry weather 12z-18z. Then thunderstorms enter western MA/CT after 18z. Some strong to severe storms possible in this region with damaging winds, large hail and low risk of isolated tornado in western MA/CT to the NY border. These storms likely weaken this afternoon as activity moves east, and may completely dissipate upon entering RI and eastern MA. N-NE wind become S-SE with time. Tonight and Friday...moderate confidence. Evening showers and thunderstorms dissipate and exit northeast into northern New England. However heavier rain shield from Elsa move north into MA/CT/RI after midnight and continue into Fri morning, then exiting west to east Fri afternoon. LLWS likely with strong SE wind jet moving across RI and southeast MA 12z- 18z Fri, with winds at 3 kft 50-60 kt from the SE. Torrential rainfall with IFR/LIFR likely. KBOS TAF...moderate confidence in TAF. TSRA should move offshore after 10z. Then mainly dry until 20z/21z when weakening storms approach from the west. KBDL TAF...moderate confidence in TAF. Mainly dry weather until 18z-23z when storms will enter from the west. A few strong to severe storms are possible in this time period, with damaging winds, large hail and low risk of an isolated tornado. Outlook /Friday Night through Monday/... Thursday Night: Mainly MVFR, with areas IFR possible. Breezy. RA, chance TSRA. Friday: Mainly MVFR, with areas IFR possible. Windy with gusts up to 35 kt. RA likely, TSRA likely. Friday Night: Mainly VFR, with areas MVFR possible. Breezy. Chance RA, chance SHRA, chance TSRA. Saturday: Mainly MVFR, with areas VFR possible. Chance SHRA, isolated TSRA.

High - greater than 60 percent. Through Tonight... Isolated/Scattered storms early this evening, then moving offshore and giving way to a drying trend.

Showers in the morning with isolated thunderstorms, then tapering off in the afternoon before picking back up again in the evening. Outlook /Friday Night through Monday/...
