Heat, humidity surge prompts advisory for much of Massachusetts on Sunday, Monday

A heat advisory will affect much of Massachusetts from Sunday at 7 a. m. until Monday at 8 p. m. , as temperatures are projected to reach the low to mid-90s.

Heat indices could peak at approximately 100 degrees on Monday, raising concerns about heat-related health risks. The humidity will be exacerbated by dew points near 70, creating a muggy atmosphere. Some isolated storms may develop on Monday in response to the high heat and humidity. However, meteorologists warn that a more significant storm system will move in on Tuesday, bringing tropical moisture from Tropical Storm Chantal. This could lead to tropical downpours with the storms that develop.

Residents are urged to stay hydrated and monitor local weather updates as conditions evolve. The National Weather Service emphasizes the importance of taking necessary precautions during this extreme heat event.
