Boston forecast calls for thunderstorms after July heat reached 100 degrees
Boston’s forecast for Sunday, Aug. 2 called for thunderstorms, with a listed high of 82 degrees and a low of 68 degrees.
The forecast page put the chance of precipitation at 51% during the late-afternoon period. The outlook is a forecast, not confirmation that storms occurred or that they became severe.
People planning outdoor activities or travel on Sunday were the groups most directly affected by the changing forecast conditions. The available reporting did not identify a Boston-specific official emergency alert.
Shift from July’s extreme heat
The thunderstorm forecast followed a July heat wave in which Boston reached 100 degrees, according to a report published July 2. That temperature was 18 degrees above the 82-degree high listed for Aug. 2.
Meteorologists also discussed the historical rarity of consecutive 100-degree days in Boston. The available report did not establish that consecutive triple-digit days occurred; it described their rarity while examining the chances for additional extreme heat.
Sunday’s listed 68-degree low also marked a substantially cooler overnight forecast than the triple-digit daytime temperature recorded during the heat wave.
What the forecast does and does not show
The forecast specifically identified thunderstorms for Boston on Aug. 2 and assigned a 51% precipitation chance to the late-afternoon period. It did not say whether any storms would bring severe conditions.
No post-event reporting in the approved material confirms storm damage, flooding, travel disruptions or injuries. The forecast therefore should not be read as evidence that such effects occurred.
The next known step is the Sunday forecast period itself. Residents and visitors with outdoor plans can use the listed thunderstorm outlook, temperatures and late-afternoon precipitation chance as the available conditions information for Aug. 2.
