Hot Heat Will Stick Around In Massachusetts: Forecasts

MARLBOROUGH, MA — Thursday's heat broke records in Massachusetts, but the stroke of hot weather isn't done with us yet.

Temperatures will stay at or above 90 degrees through at least Monday, with the National Weather Service warning of continued heat advisories over the next few days. Almost the entire state is already under a heat advisory that expires Friday at 8 p.m.

The heat index — a measure of actual temperature and humidity levels — will reach 97 on Friday, 95 on Saturday and 99 on Sunday before dipping down to a relatively cool 90 degrees on Monday, according to forecasts.

On Thursday, Logan Airport reached 97 degrees, which is a new Aug. 4 record high for the airport. The previous record for this date was set in 1928 at 96 degrees.

Starting Friday, a front will move across the state bringing a few storms with heavy rain — that'll give Massachusetts an almost tropical feel as the temperatures linger in the upper 90s, according to AccuWeather.
