New England summer weather: humid air and thunderstorms

A high‑pressure ridge kept New England under sunny, warm conditions in the mid‑70s to mid‑80s °F over the weekend of July 23‑24, with low humidity and a lingering drought. The forecast warned that daytime heating would end the dry spell early the following week, raising the chance of afternoon thunderstorms on Monday.

A subsequent Boston outlook confirmed continued sunshine for the weekend but noted that mid‑week humidity would climb sharply, increasing the likelihood of showers and isolated thunderstorms on Tuesday and Wednesday, with brief additional storm chances later in the week.

By July 25 a humid air mass was moving across the eastern United States, bringing an elevated risk of thunderstorms and heavy rain. Boston and surrounding Massachusetts areas will enjoy a final stretch of sunny, cooler weather before a low‑pressure system brings showers and possible flooding from Wednesday through Thursday. New Jersey faces spotty showers early in the week with a marginal to slight risk of severe thunderstorms Monday‑Tuesday and projected rain totals of more than an inch, prompting flood concerns. Southern West Virginia may see damaging wind gusts and heavy rainfall Tuesday, though tornado and hail threats remain low. Meteorologists advise residents to stay updated on flash‑flood and travel advisories.
