Heat Warnings For MA: Temps May Feel Like 110 In Some Areas

MASSACHUSETTS — The National Weather Service has issued heat warnings for many parts of Massachusetts, with a four-day heat wave set to begin Tuesday.

Temperatures could reach the triple-digits in some parts of the state, high enough to shatter century-old records. But the heat indices — a measure that combines humidity and air temperature — will make it feel much hotter outside.

"Dangerous heat and humidity arrives Tuesday as temperatures rise into the low to mid 90s. With dew points rising near 70F, the heat index will rise into the upper 90s to low 100s," the weather service predicted for Tuesday.

Norfolk, Middlesex and Essex counties will all be under excessive heat watches with heat index values expected at or above 105 this week. The Connecticut River Valley from the Vermont border to Springfield will also be under an excessive heat watch.

Almost the entire rest of the state from Plymouth to Pittsfield will be under a heat advisory with indices expected between 95 and 104.

"Heat and humidity peak in the Wednesday through Friday timeframe with record highs possible," the weather service tweeted Monday. "Afternoon heat indices will reach between 98 and 106 degrees away from the south coast."

But some parts of the state will remain relatively cool this week. All of Cape Cod and the Fall River area will see highs only in the mid-80s while the rest of Massachusetts swelters.

This week's heat will be especially dangerous for older residents, children and people who work outside. There will be little relief from the heat, too, with nighttime temperatures only dropping to the 70s in the hottest parts of the state.

"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors," the weather service advised.
