New England heat wave brings 90°F temps, humidity, and storms

Across southern New England the week began with mild, sunny conditions and temperatures in the 60s‑70s. A warm front moving in Monday night triggered a sharp rise in heat and humidity, with inland areas expected to reach the upper 80s to low 90s by Tuesday and Wednesday. The National Weather Service warned of sticky dew points in the 60s‑70s and the potential for strong or severe thunderstorms, especially in central and western Massachusetts.

Pollen levels remain high, especially birch, oak and ash, prompting many residents to use allergy medication. A cold front is forecast to arrive later in the week, bringing cooler temperatures back into the 60s‑70s and reducing humidity by Thursday and Friday.
